21 <sect1>What is a DX Cluster?
24 A DX Cluster is a packet node where DX chasers on any band or mode can
25 post rare or interesting stations that they have worked or heard. Of
26 course other people are doing the same thing too, so you can find new
27 DX as well as telling others about the stations you have worked.
28 Clusters tend to be linked to each other so that the amount of people
29 using them is increased, thereby increasing the amount of posted DX.
30 Other information can be found on clusters such as on-line call books,
31 mail etc. You can talk to other stations connected to the cluster
32 network too, in real time, whether at the node you are logged into or
33 on another node connected to the network. You can also use converse
34 mode, where several stations can talk to each other in the same way.
35 Of course, the DX is still posted to you all the while!
37 <sect1>So what is DXSpider?
40 PacketCluster nodes have been around since roughly 1985. The original
41 PacketCluster idea came from Dick Newell, AK1A, and ran under DOS.
42 In about 1992 Dick stopped the development of the PacketCluster
43 software for amateur radio. Many systems are still using this
44 relatively old DOS software today.
46 There are several new compatible cluster programs around now,
47 including DXSpider. DXSpider is a clone of PacketCluster software that runs
48 under the Linux operating system. Linux is fast becoming the choice
49 for amateur radio stations because of it's flexibility, reliability
50 and the lack of the memory limitations of DOS. Linux supports
51 multitasking and is also multiuser. It has support for AX25, ROSE,
52 NetROM and TCPIP built in, making it the ideal choice for amateur
53 radio. It is also totally free!
55 DXSpider was conceived and begun in 1998 by Dirk Koopman, G1TLH as an
56 exercise in perl programming. It has developed rapidly and today is a
57 very powerful cluster program. It was designed to be totally compatible
58 with the AK1A program, although several commands have been extended to
59 try and improve functionality.
61 This manual is designed to help you become familiar with the commands
62 that DXSpider supports and to help you get the best from the program so
63 you can enjoy working that rare DX! As DXSpider is being improved all the
64 time, commands will be added as time goes by, so make sure you have
65 the most upto date version of this manual. The latest version will
66 always be included with the cluster program so if you are unsure, simply
67 ask your sysop. The manual will also be available on the wesite.
70 <sect>Logins and logouts.
73 You might not think that there is a lot of point of including a
74 section on how to log in and out of DXSpider. However, you would be
75 suprised at the difficulties some people have in simply getting in
76 and out of the cluster!
78 There are several ways a login might be achieved, dependant on how
79 the sysop has DXSpider configured. It is impossible for me to cover all
80 variations but here are the basic ones.
85 Simplicity itself. The usual <bf>CONNECT</bf> command will log you straight
86 into the cluster and you will not have to do anything else.
87 Obviously, you will have to connect to the correct callsign. Some
88 nodes use an SSID with their call so you would have to add that.
100 There are several possibilities here, dependant on how the sysop has
101 configured his system. If you are connecting via netrom then you are
102 most probably connecting from another station. Listing the nodes in
103 that station with the <bf>NODES</bf> command will tell you what callsign
104 or netrom alias to connect to. Then just issue the connect command
105 from there. It is possible that the netrom alias may connect you to
106 a node with an alias for the cluster, such as DXC. Just type this
107 and you will be connected.
114 <sect1>Telnet logins.
117 Because DXSpider runs under the Linux operating system, it is possible to
118 make a direct telnet connection into the cluster. With telnet
119 connections, the source callsign is not seen by DXSpider, so you will be
120 asked to login with your callsign.
121 To telnet to DXSpider, you would connect to a specific port. There is no
122 standard at the moment for a cluster telnet port but ask the sysop if
131 All the above are possible ways of connecting to a DXSpider cluster. You
132 may have some or all of these available to you. There may be one or
133 two additional ways to connect dependant on the network local to you.
134 However I am sure you get the idea.
139 Logging out can be done by simply issuing the standard <bf>BYE</bf>
142 You could also send a disconnect if you are using AX25, or a <bf>CLOSE</bf>
143 command if you are connected via telnet.
144 If you do not log out gracefully using one of the above commands,
145 you may find you are unable to get a full connect next time. This
146 may also happen if a NETRom connection drops. You may get connected,
147 but nothing else will happen because the program thinks you are still
148 connected and will not let you connect twice under the same call.
149 However you could reconnect by adding a number to the end of your call,
151 This can be done by either altering your MYCALL setting in the TNC or
152 by altering your program configuration.
155 <sect>Setting your personal details.
158 Once logged in to the cluster, you should set your details so that
159 anybody who wishes to contact you can find out who and where you are.
160 There are four items to set, your name, qth, location and home node.
161 Setting these details also allows the use of the SHOW/HEADING and
162 SHOW/SUN commands from within the cluster. Unless you set your QTH
163 and location, these commands cannot function.
164 Once you have set your name, DXSpider will greet you with it next time
165 you login. Your QTH setting is where you live and it is a good idea
166 to add your locator to this as the location setting is converted to
167 latitude and longitude once inputted. You can actually set your location
168 in latitude/longitude or as a locator. Setting your home node will
169 tell the program where you wish mail to be sent to you.

181 <sect>Getting and posting DX.
184 When all is said and done, this is the main function of a DX cluster.
185 In its simplest form you can just connect to the node and you will
186 start to receive DX spots almost immediately! You can check on
187 recent postings in either a general manner or on a particular band or
188 mode. You can even check DX by callsign or a fragment of a callsign.
189 Of course, once you get the hang of things, it is expected that you
190 start posting some yourself! After all, there would be no clusters
191 if people did not post DX and you get the added thrill of the hunt!
196 As we have already said, it is possible just to connect to the
197 cluster and you will receive spots automatically. However, you may
198 wish to check on spots just posted. Maybe you wish to see if a
199 particular band is open or if a certain callsign is active, perhaps a
200 DXpedition. The command to do this is <bf>SHOW/DX</bf>. Without any
201 other arguments, this command will output the last 10 spots
202 posted. It is possible to look at more than this, for example the
203 last 20 or 50 spots, by adding the number to the command. You can
204 make it even more specific by adding a band in either wavelength or
205 frequency, and/or any additional information such as QSL details.
215 will show the last 10, 5 and 20 spots received by the cluster
226 will show the last 5, 10 or 20 spots on 20 metres only.
228 It is also possible to check for certain callsigns, or fragments of
229 callsigns in the same way.
238 would show the last 5 or 10 dx spots containing the callsign g0vgs.
241 You can check for DX by offset and also by specifying a comment to
252 would show the spots that arrived between 30 and 40 spots ago and any
253 spots with the word <em>iota</em> in the comment field. The case of
254 the comment is not important.
256 Checking DX posted on a certain day is possible too. All you have
257 to do here is to specify how many days ago it was like this ...
265 It is of course possible to specify multiple arguments.
270 show/dx 20 prefix 9a on vhf day 30
273 This would show the last 20 spots posted by or about calls with the prefix
274 9a on vhf 30 days ago.
276 As you can see the <bf>SHOW/DX</bf> command is very flexible, so if you are
277 not sure whether something will work or not, try it and see! More
278 information can be found in the Command Set section.
283 To post DX you use the <bf>DX</bf> command. The syntax is shown below.
288 dx (frequency) (callsign) (remarks)
291 Where frequency is in kilohertz and the callsign is the callsign of
292 the station you have worked or heard, (ie not your own callsign!).
293 The remarks section allows you to add information like the operators
294 name or perhaps a location. Actually DXSpider will allow the frequency
295 and callsign fields to be entered in any order.
300 dx 14004 pa3ezl OP Aurelio 599
303 In fact, all the following will give the same result...
306 dx 14004 pa3ezl OP Aurelio 599
307 dx pa3ezl 14004 OP Aurelio 599
308 dx pa3ezl 14.004 OP Aurelio 599
311 This posting, or callout as it is known, will be forwarded to all
312 other connected stations both at the cluster you are connected to and
313 other active clusters in the network. The callout will also be sent
314 to you as proof of receipt.
316 <sect>Headings and propagation
319 There are three commands in DXSpider to help you get the best DX possible.
320 These are <bf>SHOW/SUN</bf>, <bf>SHOW/MOON</bf> and
321 <bf>SHOW/HEADING</bf>. These commands will only work for you if you
322 have entered your personal details. They use your entered location as
323 a reference, so if you have not entered it or have entered it incorrectly
324 they will not return the correct information.
329 The <bf>SHOW/SUN</bf> command can be used in three different ways. It
330 can be used to show sunrise and sunset times for your own station, a
331 particular callsign or a prefix.
339 The output from this would look something like this ..
343 Location Rise Set Azim Elev
344 G0VGS Morecambe, Lancashire 07:08Z 17:39Z 205.3 24.1
351 would look like this ...
355 Location Rise Set Azim Elev
356 5B Cyprus-5B 04:23Z 15:40Z 244.0 18.8
359 You can also specify multiple arguments like this ...
362 sh/sun gw4veq 5b4ab zs
365 and then the output would look like this ...
368 sh/sun gw4veq 5b4ab zs
369 Location Rise Set Azim Elev
370 GW4VEQ Brungwran, Isle of Anglesey IO 07:14Z 17:48Z 204.9 24.9

373 ZS So-Africa-ZS5-ZS 03:44Z 16:34Z 278.5 32.0
374 ZS So-Africa-ZS6-ZS 03:59Z 16:42Z 277.6 35.0
380 The <bf>SHOW/MOON</bf> command works in the same way as the
381 <bf>SHOW/SUN</bf> command. This program however, calculates the
382 rise and set times of the moon for a prefix or callsign, together
383 with the current azimuth and elevation of the sun at these
392 The output from this command would look like this ..
396 Location Rise Set Azim Elev RGain dB
397 EA Spain-EA 08:15Z 20:09Z 257.2 9.5 -0.6
400 You can see that the output is similar to the <bf>SHOW/SUN</bf>
401 command, with slightly different fields.
406 The <bf>SHOW/HEADING</bf> command works in the same way as the
407 <bf>SHOW/SUN</bf> and <bf>SHOW/MOON</bf> commands but outputs beam
408 headings for a specified callsign or prefix. Reciprocal beam headings
417 The output from this command would look like this ..
421 ZL New-Zealand-ZL1-ZL: 7 degs - dist: 11238 mi, 18087 km Reciprocal heading: 355 degs
422 ZL New-Zealand-ZL2-ZL: 9 degs - dist: 11540 mi, 18574 km Reciprocal heading: 353 degs
423 ZL New-Zealand-ZL3-ZL: 19 degs - dist: 11634 mi, 18724 km Reciprocal heading: 345 degs
424 ZL New-Zealand-ZL4-ZL: 34 degs - dist: 11783 mi, 18963 km Reciprocal heading: 332 degs
429 <sect1>Making announcements.
432 Occasionally, you may wish to post something that does not fall into
433 the normal parameters for a DX callout. You may wish to tell
434 everybody connected that 10 FM is open for example, or ask if anyone
435 knows the QSL manager for a certain callsign etc. You can do this
436 using the <bf>ANNOUNCE</bf> command.
441 announce 10 FM is open in IO84NB to europe.
444 That would let everyone know locally that this was the case, however
445 it would not be forwarded to other nodes connected. To send
446 announcements to other connected nodes as well, you would use the
447 <bf>FULL</bf> extension.
452 announce full Anyone seen EA7WA today?
455 Be cautious in your use of announce full. There are many other tools
456 available to get the information you require and the judicious use of
457 this command is frowned upon as it creates a great deal of traffic
460 <sect1>Listing announcements.
463 You can list previous announcements in the standard format with the
464 <bf>SHOW</bf> command. As before you can list just the last 5 or as
471 show/announcements 10
474 <sect>Nodes and users.
477 You can check which nodes are connected in the network, who is
478 logged on locally, who is logged on at all the nodes or even
479 just one node in particular. This is handy if you wish to see whether
480 a friend is connected at the node they use. To see who is connected
481 to the nodes, the <bf>SHOW/CONFIGURATION</bf> command is used.
487 show/configuration/nodes
488 show/configuration (node_call)
489 show/configuration (prefix)
492 The first of our three examples would output something like this,
500 GB7BIG (GD0TEP) GD3UMW
501 GB7BPQ (G0INA) G0RCI G3AKU G3OCA
503 GB7DJK G0FYD G0REK G1TLH G4PEL G4SOZ
504 G4TVR G7SQW K8AZ M0CTQ-1 MM1CXE-10
507 GB7DXC (G0HDB) G0WFK (G1FYC) G3KWK G3LME
508 G3OIL G4BGW G4FUJ (G4PDQ) GW7SMV
510 (GB7DXG) GU6EFB GU7DHI
511 GB7DXK G1NTW G3IBI G3NSM G3XAQ G4CUS
513 GB7DXM G1EUC G3GAF G3LAS G4ZTR G8WXU
517 You will notice that EI5TCR is showing only that it has 7 users and not
518 giving the actual callsigns. This means that this node is on a limited
519 protocol of some kind, probably because of a contest situation where
520 slow radio links can block up and fail if too much information is sent
523 The second example would just show the nodes connected in the
529 GB7BAA GB7BAA GB7BPQ (GB7CDX) GB7DJK GB7DXA
530 GB7DXC GB7DXE (GB7DXG) GB7DXK GB7DXL
531 GB7DXM GB7DXS GB7IPT GB7MRS GB7UJS
532 GB7YDX KL7G N2TLY (ON0DXK)
533 GB7BIG EI5TCR GB7ADX GB7BIG GB7UDX
539 If we insert the node_call pi4tue-8 into the third example, then
540 this would be the output,
544 PI4TUE-8 9A1CMA-6 DF6PW DL4FAY DL4KAK DL4WF-2
545 F5NOD-2 F5PAC IZ0CSR N6CR OH2BLD
546 ON1LVL-13 ON4CBT ON4CJP ON5DXL-14 ON7NQ
547 PA0RCT PA3DYS PA3FDO PA5KW-4 PI4TUE-9
551 As you can see, only the users of the requested node are shown.
553 You can also use a prefix to show only a group of nodes. For example
554 you may only wish to see who is connected to the nodes in the UK. To
555 do this simply use a prefix like this ...
558 show/configuration gb7
561 To show the locally connected users, the <bf>SHOW/USERS</bf> command is
570 The output of this command would look like this,
573 Callsigns connected to GB7MBC
574 G0JHC G0NEI G0VGS G0VGS-2 G0YLM
581 You can send a single comment or start a dedicated talk session to
582 another user by using the <bf>TALK</bf> command.
585 Talk mode is used to send a one line comment or greeting to a
586 specific user connected either at your node or another in the
587 network. You can also enter into a dedicated talk session with
588 another user. Talks will be automatically forwarded to other nodes
589 if the station you are talking to is not connected locally.
590 You can find out who is connected by using the
591 <bf>SHOW/CONFIGURATION</bf> command, (described earlier).
596 talk g0rdi Having a good day Iain?
599 This example would send the line "Having a good day Iain?" to the
600 user g0rdi but would leave you in normal mode.
604 Entering Talkmode, /EX to end, /<cmd> to run a command
608 As you can see, you can still run commands whilst in talk mode.
609 Simply prefix the command with a / like /sh/dx and you will get
611 If the user is connected to another node, you may have to use a
612 slightly extended version of the <bf>TALK</bf> command.
618 To exit talk mode, you issue the command <bf>/ex</bf>.
620 Whilst in talk mode you will still receive DX spots. This means that
621 you can chat to a friend whilst working DX.
626 You can send and receive both personal mail and bulletins with DXSpider
629 <sect1>The "directory" command.
632 To list mail you would use the <bf>DIRECTORY</bf> command. On its
633 own, this command will output the last ten messages received by the
634 node, either to or from yourself or bulletins such as "DX" and "ALL".
635 As with other commands you can display more by specifying a number
636 with the command. You should be aware that Spider will accept
637 these commands by separating with either a slash or a space, so
638 <em>dir new</em> and <em>dir/new</em> work in the same way.
648 Of course most of the time you will only want to list new mail sent
649 to you personally since your last login. However you might also like
650 to check for general mail received by the node. In fact if there is
651 new mail for you, the cluster will tell you when you login. You will
652 also be informed if new mail arrives for you during the time you are
654 Mail is not only sent to callsigns though. Mail can also be sent to
655 subjects like "all" or "local" or "dx" etc. You can treat these
656 bulletins in the same way as personal mail with the directory
666 directory/from <call>
669 The last option will only show mail from a callsign if it was sent to
670 you personally or was sent as a bulletin. There are some additional
671 commands and these can be found in the DXSpider Command Reference section.
676 The output of the <bf>DIRECTORY</bf> command could be something like

694 The first column is the actual message number. If the message is a
695 personal one to you, you will see a letter 'p' after this number. If
696 the message has been read, there will be a '-' between the message
697 number and the 'p'. This only works for personal messages. The next
698 column shows the file size of the message. The third column shows the
699 address the message was sent to and the next column shows who sent it.
700 The rest is fairly self-explanatory.
702 Reading a message is as simple as typing read, followed by the
703 message number that you wish to read.
711 will read message number 25. However the mail will be displayed in it's
712 entirety unless you specify a page length. You can set your page length
713 to any number you like and when the message reaches that number of lines
714 you will get a prompt giving you options.
726 Sending mail is done in the time honoured way. First you specify
727 a recipient for the message, then you will be prompted for a subject.
728 Once you have done this you will be asked to type your message.
729 Please remember that there is no automatic word wrap, so unless you
730 are using a client that wraps lines automatically, remember to hit
731 return at the end of each line.
737 Enter Subject (30 characters):
739 Enter Message /EX to send or /ABORT to exit
741 Just a quick note to say that I can make Thursday after all. The
742 appointment I had has cancelled so we are go!
747 At this point you can either hit return and enter /ex to send the
748 message or use /abort at any time to abort it. You can now display
749 the message in the normal way. There are several send options and
750 these are listed in the Command Set section. These include sending
751 mail to several recipients and asking for a return receipt.
754 <sect1>Replying to mail.
757 If mail is addressed to you or to a bulletin address, you can use the
758 <bf>REPLY</bf> command to reply to it. Using this command, the
759 subject will be automatically set for you as "Re: subject", whatever
771 To delete a message, you use the <em>delete</em> command.
772 You can only delete messages sent to or received by yourself.
773 Bulletins are dealt with automatically or by the sysop.
775 <sect>Filtering (From version 1.45)
777 <sect1>General filter rules
780 Upto v1.44 it was not possible for the user to set their own filters. From
781 v1.45 though that has all changed. It is now possible to set filters for just
782 about anything you wish. If you have just updated from an older version of
783 DXSpider you will need to update your new filters. You do not need to do
784 anything with your old filters, they will be renamed as you update.
787 There are 3 basic commands involved in setting and manipulating filters. These
788 are <em>accept</em>, <em>reject</em> and <em>clear</em>. First we will look
789 generally at filtering. There are a number of things you can filter in the
790 DXSpider system. They all use the same general mechanism.
793 In general terms you can create a 'reject' or an 'accept' filter which can have
794 up to 10 lines in it. You do this using, for example ...
801 where ..... are the specific commands for that type of filter. There are
802 filters for spots, wwv, announce, wcy and (for sysops) connects. See each
803 different accept or reject command reference for more details.
805 There is also a command to clear out one or more lines in a filter. They are ...
812 There is clear/xxxx command for each type of filter.
815 and you can check that your filters have worked by the command ...
822 For now we are going to use spots for the examples, but you can apply the same
823 principles to all types of filter.
825 <sect1>Types of filter
828 There are two main types of filter, <em>accept</em> or <em>reject</em>. You
829 can use either to achieve the result you want dependent on your own preference
830 and which is more simple to do. It is pointless writing 8 lines of reject
831 filters when 1 accept filter would do the same thing! Each filter has 10
832 lines (of any length) which are tried in order. If a line matches then the
833 action you have specified is taken (ie reject means ignore it and accept
837 If you specify reject filters, then any lines that arrive that match the filter
838 will be dumped but all else will be accepted. If you use an accept filter,
839 then ONLY the lines in the filter will be accepted and all else will be dumped.
840 For example if you have a single line <em>accept</em> filter ...
843 accept/spots on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
846 then you will <em>ONLY</em> get VHF spots <em>from</em> or <em>to</em> CQ zones
850 If you set a reject filter like this ...
853 reject/spots on hf/cw
856 Then you will get everything <em>EXCEPT</em> HF CW spots. You could make this
857 single filter even more flexible. For example, if you are interested in IOTA
858 and will work it even on CW even though normally you are not interested in
859 CW, then you could say ...
862 reject/spots on hf/cw and not info iota
865 But in that case you might only be interested in iota and say:-
868 accept/spots not on hf/cw or info iota
871 which achieves exactly the same thing. You should choose one or the other
872 until you are comfortable with the way it works. You can mix them if you
873 wish (actually you can have an accept AND a reject on the same line) but
874 don't attempt this until you are sure you know what you are doing!
877 You can arrange your filter lines into logical units, either for your own
878 understanding or simply convenience. Here is an example ...
881 reject/spots 1 on hf/cw
882 reject/spots 2 on 50000/1400000 not (by_zone 14,15,16 or call_zone 14,15,16)
885 What this does is to ignore all HF CW spots and also rejects any spots on VHF
886 which don't either originate or spot someone in Europe.
889 This is an example where you would use a line number (1 and 2 in this case), if
890 you leave the digit out, the system assumes '1'. Digits '0'-'9' are available.
891 This make it easier to see just what filters you have set. It also makes it
892 more simple to remove individual filters, during a contest for example.
895 You will notice in the above example that the second line has brackets. Look
896 at the line logically. You can see there are 2 separate sections to it. We
897 are saying reject spots that are VHF or above <em>APART</em> from those in
898 zones 14, 15 and 16 (either spotted there or originated there). If you did
899 not have the brackets to separate the 2 sections, then Spider would read it
900 logically from the front and see a different expression entirely ...
903 (on 50000/1400000 and by_zone 14,15,16) or call_zone 14,15,16
906 The simple way to remember this is, if you use OR - use brackets. Whilst we are
907 here CASE is not important. 'And BY_Zone' is just the same as 'and by_zone'.
909 As mentioned earlier, setting several filters can be more flexible than
910 simply setting one complex one. Doing it in this way means that if you want
911 to alter your filter you can just redefine or remove one or more lines of it or
912 one line. For example ...
915 reject/spots 1 on hf/ssb
918 would redefine our earlier example, or
924 To remove all the filter lines in the spot filter ...
930 <sect1>Filter options
933 You can filter in several different ways. The options are listed in the
934 various helpfiles for accept, reject and filter.
936 <sect1>Advanced filtering
939 Once you are happy with the results you get, you may like to experiment.
942 The previous example that filters hf/cw spots and accepts vhf/uhf spots from EU
943 can be written with a mixed filter, for example ...
948 acc/spot 2 on 50000/1400000 and (by_zone 14,15,16 or call_zone 14,15,16)
951 Note that the first filter has not been specified with a number. This
952 will automatically be assumed to be number 1. In this case, we have
953 said <em>reject all HF spots in the CW section of the bands but accept
954 all others at HF. Also accept anything in VHF and above spotted in or
955 by operators in the zones 14, 15 and 16</em>. Each filter slot actually
956 has a 'reject' slot and an 'accept' slot. The reject slot is executed
957 BEFORE the accept slot.
960 It was mentioned earlier that after a reject test that doesn't match, the
961 default for following tests is 'accept', the reverse is true for 'accept'.
962 In the example what happens is that the reject is executed first, any non
963 hf/cw spot is passed to the accept line, which lets through everything
964 else on HF. The next filter line lets through just VHF/UHF spots from EU.
967 <sect>Hints, tips and common questions.
970 <bf/Q./These commands seem very long! Can I shorten them?
972 <bf/A./Of course you can and the usual abbreviations work. If you
975 <bf/Q./I am not sure if this command is correct. Can I cause any
978 <bf/A./Do not be afraid to try a command to see if it will work,
979 at the worst you will get an error message. If you require any
980 help on a command, just type help followed by the command you
981 want help on. Look at the "DXSpider Command Reference" section to see
982 what help can be found.
984 <bf/Q./How should I use the announce command?
986 <bf/A./With respect. Use the command by all means, but please
987 only use the "full" extension if absolutely necessary. It can
988 create a LOT of messages passing between clusters.
990 <bf/Q./I like to be working in the shack while logged into the
991 cluster but I can't be looking at the screen all the time. How
992 can I be alerted when anything happens?
994 <bf/A./Use the <bf>SET/BEEP</bf> command. You can find information
995 on this in the "DXSpider Command Reference" section.
997 <bf/Q./I keep getting disconnected from the cluster, what is
998 happening and how can I stop it?
1000 <bf/Q./I got disconnected from the cluster and now I can't log
1001 back in again. What is wrong?
1003 <bf/A./Probably the cluster thinks you are still logged on and
1004 will not let you reconnect using the same call to prevent loops.
1005 Try logging on again adding an ssid to your callsign as DXSpider
1006 treats G0YLM and G0YLM-1 as different users.
1008 <bf/Q./I notice that all the commands are shown in lower case in
1009 the main section of this manual, but in upper case in the "DXSpider
1010 Command Reference" section. Why is that?
1012 <bf/Q./How do I know if I have got the latest version of this
1015 <bf/A./The latest and greatest will always be on the Website. It will
1016 also be included with every release of DXSpider. As always, if unsure,
1017 ask your sysop what version number is the latest.
1019 <sect>The DXSpider command reference
1022 Below is a complete list of commands available from the cluster prompt.
1023 These are listed below in alphabetical order.
1025 <sect1>accept/announce
1029 <bf>accept/announce [0-9] <pattern></bf> Set an accept filter
1034 Create an 'accept this announce' line for a filter.
1036 An accept filter line means that if the announce matches this filter it is
1037 passed onto the user. See HELP FILTERS for more info. Please read this
1038 to understand how filters work - it will save a lot of grief later on.
1040 You can use any of the following things in this line:-
1043 info <string> eg: iota or qsl
1044 by <prefixes> eg: G,M,2
1046 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1047 origin_itu <numbers>
1048 origin_zone <numbers>
1053 wx 1 filter WX announces
1054 dest <prefixes> eg: 6MUK,WDX (distros)
1061 acc/ann 2 by_zone 14,15,16
1062 (this could be all on one line: acc/ann dest 6MUK or by_zone 14,15,16)
1071 This filter would only allow announces that were posted buy UK stations.
1072 You can use the tag 'all' to accept everything eg:
1078 but this probably for advanced users...
1084 <bf>accept/announce [0-9] <pattern></bf> Set an accept filter
1089 Create an 'accept this spot' line for a filter.
1092 An accept filter line means that if the spot matches this filter it is
1093 passed onto the user. See HELP FILTERS for more info. Please read this
1094 to understand how filters work - it will save a lot of grief later on.
1096 You can use any of the following things in this line:-
1099 freq <range> eg: 0/30000 or hf or hf/cw or 6m,4m,2m
1100 on <range> same as 'freq'
1101 call <prefixes> eg: G,PA,HB9
1102 info <string> eg: iota or qsl
1104 call_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1115 For frequencies, you can use any of the band names defined in
1116 SHOW/BANDS and you can use a subband name like: cw, rtty, data, ssb -
1117 thus: hf/ssb. You can also just have a simple range like: 0/30000 -
1118 this is more efficient than saying simply: freq HF (but don't get
1119 too hung up about that)
1125 acc/spot 2 on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
1128 You can use the tag 'all' to accept everything, eg:
1134 but this probably for advanced users...
1140 <bf>accept/wcy [0-9] <pattern></bf> set an accept WCY filter
1144 It is unlikely that you will want to do this, but if you do then you can
1145 filter on the following fields:-
1148 by <prefixes> eg: G,M,2
1150 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1151 origin_itu <numbers>
1152 origin_zone <numbers>
1160 There are no examples because WCY Broadcasts only come from one place and
1161 you either want them or not (see UNSET/WCY if you don't want them).
1163 This command is really provided for future use.
1165 See HELP FILTER for information.
1171 <bf>accept/wwv [0-9] <pattern></bf> Set an accept WWV filter
1175 It is unlikely that you will want to do this, but if you do then you can
1176 filter on the following fields:-
1179 by <prefixes> eg: G,M,2
1181 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1182 origin_itu <numbers>
1183 origin_zone <numbers>
1193 accept/wwv by_zone 4
1196 is probably the only useful thing to do (which will only show WWV broadcasts
1197 by stations in the US).
1199 See HELP FILTER for information.
1205 <bf>announce <text></bf> Send an announcement to local users
1209 Send an announcement to LOCAL users only, where <text> is the text
1210 of the announcement you wish to broadcast
1212 <sect1>announce full
1216 <bf>announce full <text></bf> Send an announcement cluster wide
1220 This command will send your announcement across the whole cluster
1227 <bf>apropos <string></bf> Search the help database
1231 Search the help database for <string> (it isn't case sensitive),
1232 and print the names of all the commands that may be relevant.
1238 <bf>bye</bf> Exit from the cluster
1242 This will disconnect you from the cluster
1248 <bf>clear/spots [1|all]</bf> Clear a spot filter line
1252 This command allows you to clear (remove) a line in a spot filter or to
1253 remove the whole filter.
1255 If you have a filter:-
1259 acc/spot 2 on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
1268 you will be left with:-
1271 acc/spot 2 on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
1280 the filter will be completely removed.
1286 <bf>dbavail</bf> Show a list of all the databases in the system
1290 The title says it all really, this command lists all the databases defined
1291 in the system. It is also aliased to SHOW/COMMAND.
1297 <bf>dbshow <dbname> <key></bf> Display an entry, if it exists,
1302 This is the generic user interface to the database to the database system.
1303 It is expected that the sysop will add an entry to the local Aliases file
1304 so that users can use the more familiar AK1A style of enquiry such as:
1310 but if he hasn't and the database really does exist (use DBAVAIL or
1311 SHOW/COMMAND to find out) you can do the same thing with:
1321 <bf>directory</bf> List messages<newline>
1322 <bf>directory all</bf> List all messages<newline>
1323 <bf>directory own</bf> List your own messages<newline>
1324 <bf>directory new</bf> List all new messages<newline>
1325 <bf>directory to <call></bf> List all messages to <call><newline>
1326 <bf>directory from <call></bf> List all messages from <call><newline>
1327 <bf>directory subject <string></bf> List all messages with <string>
1329 <bf>directory <nn></bf> List last <nn> messages<newline>
1330 <bf>directory <from>-<to></bf> List messages <from> message <to> message <newline>
1334 List the messages in the messages directory.
1336 If there is a 'p' one space after the message number then it is a
1337 personal message. If there is a '-' between the message number and the
1338 'p' then this indicates that the message has been read.
1340 You can use shell escape characters such as '*' and '?' in the <call>
1343 You can combine some of the various directory commands together eg:-
1348 DIR SUBJECT IOTA 200-250
1351 You can abbreviate all the commands to one letter and use ak1a syntax:-
1362 <bf>dx [by <call>] <freq> <call> <remarks></bf> Send a DX spot
1366 This is how you send a DX Spot to other users. You can, in fact, now
1367 enter the <freq> and the <call> either way round.
1375 will all give the same result. You can add some remarks to the end
1376 of the command and they will be added to the spot.
1379 DX FR0G 144600 this is a test
1382 You can credit someone else by saying:-
1385 DX by G1TLH FR0G 144.600 he isn't on the cluster
1388 The <freq> is compared against the available bands set up in the
1389 cluster. See SHOW/BANDS for more information.
1395 <bf>help <cmd></bf> Get help on a command
1399 All commands can be abbreviated, so SHOW/DX can be abbreviated
1400 to SH/DX, ANNOUNCE can be shortened to AN and so on.
1402 Look at the APROPOS <string> command which will search the help database
1403 for the <string> you specify and give you a list of likely commands
1404 to look at with HELP.
1410 <bf>kill <msgno> [<msgno> ..]</bf> Delete a message
1411 from the local system
1415 Delete a message from the local system. You will only be able to
1416 delete messages that you have originated or been sent (unless you are
1423 <bf>links</bf> Show which nodes are physically connected
1427 This is a quick listing that shows which links are connected and
1428 some information about them. See WHO for a list of all connections.
1434 <bf>read</bf> Read the next unread personal message addressed to you<newline>
1435 <bf>read <msgno></bf> Read the specified message<newline>
1439 You can read any messages that are sent as 'non-personal' and also any
1440 message either sent by or sent to your callsign.
1442 <sect1>reject/announce
1446 <bf>reject/announce [0-9] <pattern></bf> Set a reject filter
1451 Create an 'reject this announce' line for a filter.
1453 An reject filter line means that if the announce matches this filter it is
1454 passed onto the user. See HELP FILTERS for more info. Please read this
1455 to understand how filters work - it will save a lot of grief later on.
1457 You can use any of the following things in this line:-
1460 info <string> eg: iota or qsl
1461 by <prefixes> eg: G,M,2
1463 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1464 origin_itu <numbers>
1465 origin_zone <numbers>
1470 wx 1 filter WX announces
1471 dest <prefixes> eg: 6MUK,WDX (distros)
1477 rej/ann by_zone 14,15,16 and not by G,M,2
1480 You can use the tag 'all' to reject everything eg:
1486 but this probably for advanced users...
1492 <bf>reject/spots [0-9] <pattern></bf> Set a reject filter
1497 Create a 'reject this spot' line for a filter.
1499 A reject filter line means that if the spot matches this filter it is
1500 dumped (not passed on). See HELP FILTERS for more info. Please read this
1501 to understand how filters work - it will save a lot of grief later on.
1503 You can use any of the following things in this line:-
1506 freq <range> eg: 0/30000 or hf or hf/cw or 6m,4m,2m
1507 on <range> same as 'freq'
1508 call <prefixes> eg: G,PA,HB9
1509 info <string> eg: iota or qsl
1511 call_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1521 For frequencies, you can use any of the band names defined in
1522 SHOW/BANDS and you can use a subband name like: cw, rtty, data, ssb -
1523 thus: hf/ssb. You can also just have a simple range like: 0/30000 -
1524 this is more efficient than saying simply: on HF (but don't get
1525 too hung up about that)
1531 rej/spot 2 on vhf and not (by_zone 14,15,16 or call_zone 14,15,16)
1534 You can use the tag 'all' to reject everything eg:
1540 but this probably for advanced users...
1546 <bf>reject/wcy [0-9] <pattern></bf> Set a reject WCY filter
1550 It is unlikely that you will want to do this, but if you do then you can
1551 filter on the following fields:-
1554 by <prefixes> eg: G,M,2
1556 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1557 origin_itu <numbers>
1558 origin_zone <numbers>
1565 There are no examples because WCY Broadcasts only come from one place and
1566 you either want them or not (see UNSET/WCY if you don't want them).
1568 This command is really provided for future use.
1570 See HELP FILTER for information.
1576 <bf>reject/wwv [0-9] <pattern></bf> Set a reject WWV filter
1580 It is unlikely that you will want to do this, but if you do then you can
1581 filter on the following fields:-
1584 by <prefixes> eg: G,M,2
1586 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
1587 origin_itu <numbers>
1588 origin_zone <numbers>
1598 reject/wwv by_zone 14,15,16
1601 is probably the only useful thing to do (which will only show WWV broadcasts
1602 by stations in the US).
1604 See HELP FILTER for information.
1610 <bf>reply</bf> Reply (privately) to the last message that you have read<newline>
1611 <bf>reply <msgno></bf> Reply (privately) to the specified message<newline>
1612 <bf>reply B <msgno></bf> Reply as a Bulletin to the specified message<newline>
1613 <bf>reply NOPrivate <msgno></bf> Reply as a Bulletin to the specified
1615 <bf>reply RR <msgno></bf> Reply to the specified message with read
1620 You can reply to a message and the subject will automatically have
1621 "Re:" inserted in front of it, if it isn't already present.
1623 You can also use all the extra qualifiers such as RR, PRIVATE,
1624 NOPRIVATE, B that you can use with the SEND command (see SEND
1625 for further details)
1631 <bf>send <call> [<call> ...]</bf> Send a message to
1632 one or more callsigns<newline>
1633 <bf>send RR <call></bf> Send a message and ask for a read receipt<newline>
1634 <bf>send COPY <msgno> <call></bf> Send a copy of a message
1636 <bf>send PRIVATE <call></bf> Send a personal message<newline>
1637 <bf>send NOPRIVATE <call></bf> Send a message to all stations<newline>
1641 All the SEND commands will create a message which will be sent either to
1642 an individual callsign or to one of the 'bulletin' addresses.
1644 SEND <call> on its own acts as though you had typed SEND PRIVATE, that is
1645 it will mark the message as personal and send it to the cluster node that
1646 that callsign is connected to.
1648 You can have more than one callsign in all of the SEND commands.
1650 You can have multiple qualifiers so that you can have for example:-
1653 SEND RR COPY 123 PRIVATE G1TLH G0RDI
1656 which should send a copy of message 123 to G1TLH and G0RDI and you will
1657 receive a read receipt when they have read the message.
1659 SB is an alias for SEND NOPRIVATE (or send a bulletin in BBS speak)
1660 SP is an alias for SEND PRIVATE
1666 <bf>set/address <your_address></bf> Record your postal address
1670 Literally, record your address details on the cluster.
1676 <bf>set/announce</bf> Allow announce messages
1680 Allow announce messages to arrive at your terminal.
1686 <bf>set/beep</bf> Add beeps to terminal messages
1690 Add a beep to DX and other terminal messages.
1696 <bf>set/dx</bf>Allow DX messages to arrive at your terminal
1700 You can stop DX messages with the <em>unset/dx</em> command
1706 <bf>set/dxgrid</bf>Allow grid squares on the end of DX messages
1710 Some logging programs do not like the additional information at
1711 the end of a DX spot. If this is the case, use the <em>unset/dxgrid</em>
1712 command to remove the grid squares.
1718 <bf>set/echo</bf> Make the cluster echo your input
1722 If you are connected via a telnet session, different implimentations
1723 of telnet handle echo differently depending on whether you are
1724 connected via port 23 or some other port. You can use this command
1725 to change the setting appropriately.
1727 You can remove the echo with the <em>unset/echo</em> command
1729 The setting is stored in your user profile.
1731 YOU DO NOT NEED TO USE THIS COMMAND IF YOU ARE CONNECTED VIA AX25.
1737 <bf>set/here</bf> Set the here flag
1741 Let others on the cluster know you are here by only displaying your
1742 callsign. If you are away from your terminal you can use the <em>unset/here</em>
1743 command to let people know you are away. This simply puts brackets
1744 around your callsign to indicate you are not available.
1750 <bf>set/homenode <node_call></bf> Set your home cluster
1754 Tell the cluster system where you normally connect to. Any Messages sent
1755 to you will normally find their way there should you not be connected.
1766 <bf>set/language <language></bf> Set the language you wish to use
1770 You can select the language that you want the cluster to use. Currently
1771 the languages available are <em>en</em> (English) <em>sp</em> (Spanish)
1772 and <em>nl</em> (Dutch).
1778 <bf>set/location <lat and long></bf> Set your latitude and longitude
1782 You can set your latitude and longitude manually or alternatively use the
1783 <em>set/qra</em> command which will do the conversion for you.
1786 set/location 54 04 N 2 02 E
1789 <sect1>set/logininfo
1793 <bf>set/logininfo</bf> Show logins and logouts of nodes and users
1797 Show users and nodes when they log in and out of the local cluster. You
1798 can stop these messages by using the <em>unset/logininfo</em> command.
1804 <bf>set/name <your_name></bf> Set your name
1808 Tell the cluster what your name is, eg:-
1818 <bf>set/page <n></bf> Set the number of lines per page
1822 Tell the system how many lines you wish on a page when the number of lines
1823 of output from a command is more than this. The default is 20. Setting it
1824 explicitly to 0 will disable paging.
1831 The setting is stored in your user profile.
1837 <bf>set/qra <locator></bf> Set your QRA locator
1841 Tell the system what your QRA (or Maidenhead) locator is. If you have not
1842 done a SET/LOCATION then your latitude and longitude will be set roughly
1843 correctly (assuming your locator is correct ;-). For example:-
1853 <bf>set/qth <your QTH></bf> Set your QTH
1857 Tell the system where your are. For example:-
1860 set/qth East Dereham, Norfolk
1867 <bf>set/talk</bf> Allow talk messages to be seen at your console
1871 Allow talk messages to arrive at your console. You can switch off
1872 talks with the <em>unset/talk</em> command.
1878 <bf>set/wcy</bf> Allow WCY messages to be seen at your console
1882 Allow WCY information to be seen at your console. You can switch off
1883 WCY messages with the <em>unset/wcy</em> command.
1889 <bf>set/wwv</bf> Allow WWV messages to be seen at your console
1893 Allow WWV information to be seen at your console. You can switch off
1894 WWV messages with the <em>unset/wwv</em> command.
1900 <bf>set/wx</bf> Allow WX messages to be seen at your console
1904 Allow WX information to be seen at your console. You can switch off
1905 WX messages with the <em>unset/wx</em> command.
1911 <bf>show/date [<prefix>|<callsign>]</bf> Show
1916 This is very nearly the same as SHOW/TIME, the only difference the format
1917 of the date string if no arguments are given.
1919 If no prefixes or callsigns are given then this command returns the local
1920 time and UTC as the computer has it right now. If you give some prefixes
1921 then it will show UTC and UTC + the local offset (not including DST) at
1922 the prefixes or callsigns that you specify.
1928 <bf>show/dx [options]</bf> interrogate the spot database
1932 If you just type SHOW/DX you will get the last so many spots
1933 (sysop configurable, but usually 10).
1935 In addition you can add any number of these options in very nearly
1936 any order to the basic SHOW/DX command, they are:-
1939 on <band> - eg 160m 20m 2m 23cm 6mm
1940 on <region> - eg hf vhf uhf shf (see SHOW/BANDS)
1942 <number> - the number of spots you want
1943 <from>-<to> - <from> spot no <to> spot no in
1946 <prefix> - for a spotted callsign beginning with <prefix>
1947 *<suffix> - for a spotted callsign ending in <suffix>
1948 *<string>* - for a spotted callsign containing <string>
1950 day <number> - starting <number> days ago
1951 day <from>-<to> - <from> days <to> days ago
1953 info <text> - any spots containing <text> in the info or remarks
1955 by <call> - any spots spotted by <call> (spotter <call>
1958 qsl - this automatically looks for any qsl info on the call
1959 held in the spot database.
1961 iota [<iota>] - If the iota island number is missing it will
1962 look for the string iota and anything which looks like
1963 an iota island number. If you specify then it will look
1966 qra [<locator>] - this will look for the specific locator if
1967 you specify one or else anything that looks like a locator.
1974 SH/DX on 20m info iota
1975 SH/DX 9a on vhf day 30
1986 <bf>show/dxcc <prefix></bf> Interrogate the spot database by country
1990 This command takes the <prefix> (which can be a full or partial
1991 callsign if desired), looks up which internal country number it is
1992 and then displays all the spots as per SH/DX for that country.
1994 The options for SHOW/DX also apply to this command.
1999 SH/DXCC W on 20m info iota
2006 <bf>show/files [<filearea> [<string>]]</bf> List
2007 the contents of a filearea
2011 SHOW/FILES on its own will show you a list of the various fileareas
2012 available on the system. To see the contents of a particular file
2016 SH/FILES <filearea>
2019 where <filearea> is the name of the filearea you want to see the
2022 You can also use shell globbing characters like '*' and '?' in a
2023 string to see a selection of files in a filearea eg:-
2026 SH/FILES bulletins arld*
2029 See also TYPE - to see the contents of a file.
2035 <bf>show/filter</bf> Show the filters you have set
2039 Show the contents of all the filters that are set by you. This command
2040 displays all the filters set - for all the various categories.
2046 <bf>show/moon [<prefix>|<callsign>]</bf> Show moon
2051 Show the Moon rise and set times for a (list of) prefixes or callsigns,
2052 together with the azimuth and elevation of the sun currently at those
2055 If you don't specify any prefixes or callsigns, it will show the times for
2056 your QTH (assuming you have set it with either SET/LOCATION or SET/QRA),
2057 together with the current azimuth and elevation.
2059 In addition, it will show the gain or loss dB relative to the nominal
2060 distance of 385,000Km due to the ellipsoidal nature of the orbit.
2062 If all else fails it will show the Moonrise and set times for the node
2063 that you are connected to.
2076 <bf>show/muf <prefix> [<hours>][long]</bf> Show
2077 the likely propagation to <prefix>
2081 This command allow you to estimate the likelihood of you contacting
2082 a station with the prefix you have specified. The output assumes a modest
2083 power of 20dBW and receiver sensitivity of -123dBm (about 0.15muV/10dB SINAD)
2085 The result predicts the most likely operating frequencies and signal
2086 levels for high frequency (shortwave) radio propagation paths on
2087 specified days of the year and hours of the day. It is most useful for
2088 paths between 250 km and 6000 km, but can be used with reduced accuracy
2089 for paths shorter or longer than this.
2091 The command uses a routine MINIMUF 3.5 developed by the U.S. Navy and
2092 used to predict the MUF given the predicted flux, day of the year,
2093 hour of the day and geographic coordinates of the transmitter and
2094 receiver. This routine is reasonably accurate for the purposes here,
2095 with a claimed RMS error of 3.8 MHz, but much smaller and less complex
2096 than the programs used by major shortwave broadcasting organizations,
2097 such as the Voice of America.
2099 The command will display some header information detailing its
2100 assumptions, together with the locations, latitude and longitudes and
2101 bearings. It will then show UTC (UT), local time at the other end
2102 (LT), calculate the MUFs, Sun zenith angle at the midpoint of the path
2103 (Zen) and the likely signal strengths. Then for each frequency for which
2104 the system thinks there is a likelihood of a circuit it prints a value.
2106 The value is currently a likely S meter reading based on the conventional
2107 6dB / S point scale. If the value has a '+' appended it means that it is
2108 1/2 an S point stronger. If the value is preceeded by an 'm' it means that
2109 there is likely to be much fading and by an 's' that the signal is likely
2112 By default SHOW/MUF will show the next two hours worth of data. You
2113 can specify anything up to 24 hours worth of data by appending the no of
2114 hours required after the prefix. For example:-
2123 RxSens: -123 dBM SFI: 159 R: 193 Month: 10 Day: 21
2124 Power : 20 dBW Distance: 6283 km Delay: 22.4 ms
2125 Location Lat / Long Azim

2128 UT LT MUF Zen 1.8 3.5 7.0 10.1 14.0 18.1 21.0 24.9 28.0 50.0
2129 18 23 11.5 -35 mS0+ mS2 S3
2130 19 0 11.2 -41 mS0+ mS2 S3
2133 indicating that you will have weak, fading circuits on top band and
2134 80m but usable signals on 40m (about S3).
2142 will get you the above display, but with the next 24 hours worth of
2150 Gives you an estimate of the long path propagation characterics. It
2151 should be noted that the figures will probably not be very useful, nor
2152 terrible accurate, but it is included for completeness.
2158 <bf>show/prefix <callsign></bf> Interrogate the prefix database
2162 This command takes the <callsign> (which can be a full or partial
2163 callsign or a prefix), looks up which internal country number
2164 it is and then displays all the relevant prefixes for that country
2165 together with the internal country no, the CQ and ITU regions.
2173 <bf>show/qra <locator> [<locator>]</bf> Show the distance
2174 between locators<newline>
2175 <bf>show/qra <lat> <long></bf> Convert latitude and longitude to
2180 This is a multipurpose command that allows you either to calculate the
2181 distance and bearing between two locators or (if only one locator is
2182 given on the command line) the distance and beraing from your station
2183 to the locator. For example:-
2190 The first example will show the distance and bearing to the locator from
2191 yourself, the second example will calculate the distance and bearing from
2192 the first locator to the second. You can use 4 or 6 character locators.
2194 It is also possible to convert a latitude and longitude to a locator by
2195 using this command with a latitude and longitude as an argument, for
2199 SH/QRA 52 41 N 0 58 E
2206 <bf>show/qrz <callsign></bf> Show any callbook details on a callsign
2210 This command queries the QRZ callbook server on the internet
2211 and returns any information available for that callsign. This service
2212 is provided for users of this software by http://www.qrz.com
2218 <bf>show/route <callsign></bf> Show the route to <callsign>
2222 This command allows you to see to which node the callsigns specified are
2223 connected. It is a sort of inverse sh/config.
2229 <sect1>show/satellite
2233 <bf>show/satellite <name> [<hours> <interval>]</bf>
2234 Show satellite tracking data
2238 Show the tracking data from your location to the satellite of your choice
2239 from now on for the next few hours.
2241 If you use this command without a satellite name it will display a list
2242 of all the satellites known currently to the system.
2244 If you give a name then you can obtain tracking data of all the passes
2245 that start and finish 5 degrees below the horizon. As default it will
2246 give information for the next three hours for every five minute period.
2248 You can alter the number of hours and the step size, within certain
2251 Each pass in a period is separated with a row of '-----' characters
2257 SH/SAT FENGYUN1 12 2
2264 <bf>show/sun [<prefix>|<callsign>]</bf> Show
2265 sun rise and set times
2269 Show the sun rise and set times for a (list of) prefixes or callsigns,
2270 together with the azimuth and elevation of the sun currently at those
2273 If you don't specify any prefixes or callsigns, it will show the times for
2274 your QTH (assuming you have set it with either SET/LOCATION or SET/QRA),
2275 together with the current azimuth and elevation.
2277 If all else fails it will show the sunrise and set times for the node
2278 that you are connected to.
2284 SH/SUN G1TLH K9CW ZS
2291 <bf>show/time [<prefix>|<callsign>]</bf> Show
2296 If no prefixes or callsigns are given then this command returns the local
2297 time and UTC as the computer has it right now. If you give some prefixes
2298 then it will show UTC and UTC + the local offset (not including DST) at
2299 the prefixes or callsigns that you specify.
2305 <bf>show/wcy</bf> Show the last 10 WCY broadcasts<newline>
2306 <bf>show/wcy <n></bf> Show the last <n> WCY broadcasts
2310 Display the most recent WCY information that has been received by the system
2316 <bf>show/wwv</bf> Show the last 10 WWV broadcasts<newline>
2317 <bf>show/wwv <n></bf> Show the last <n> WWV broadcasts
2321 Display the most recent WWV information that has been received by the system
2327 <bf>sysop</bf> Regain your privileges if you login remotely
2331 The system automatically reduces your privilege level to that of a
2332 normal user if you login in remotely. This command allows you to
2333 regain your normal privilege level. It uses the normal system: five
2334 numbers are returned that are indexes into the character array that is
2335 your assigned password (see SET/PASSWORD). The indexes start from
2338 You are expected to return a string which contains the characters
2339 required in the correct order. You may intersperse those characters
2340 with others to obscure your reply for any watchers. For example (and
2341 these values are for explanation :-):
2344 password = 012345678901234567890123456789
2352 aa2bbbb0ccc5ddd7xxx3n
2357 They will all match. If there is no password you will still be offered
2358 numbers but nothing will happen when you input a string. Any match is
2365 <bf>talk <callsign></bf> Enter talk mode with <callsign><newline>
2366 <bf>talk <callsign> <text></bf> Send a text message to <callsign><newline>
2367 <bf>talk <callsign> > <node_call> [<text>]</bf>
2368 Send a text message to <callsign> via <node_call>
2372 Send a short message to any other station that is visible on the cluster
2373 system. You can send it to anyone you can see with a SHOW/CONFIGURATION
2374 command, they don't have to be connected locally.
2376 The second form of TALK is used when other cluster nodes are connected
2377 with restricted information. This usually means that they don't send
2378 the user information usually associated with logging on and off the cluster.
2380 If you know that G3JNB is likely to be present on GB7TLH, but you can only
2381 see GB7TLH in the SH/C list but with no users, then you would use the
2382 second form of the talk message.
2384 If you want to have a ragchew with someone you can leave the text message
2385 out and the system will go into 'Talk' mode. What this means is that a
2386 short message is sent to the recipient telling them that you are in a 'Talking'
2387 frame of mind and then you just type - everything you send will go to the
2388 station that you asked for.
2390 All the usual announcements, spots and so on will still come out on your
2393 If you want to do something (such as send a spot) you precede the normal
2394 command with a '/' character, eg:-
2397 /DX 14001 G1TLH What's a B class licensee doing on 20m CW?
2401 To leave talk mode type:
2411 <bf>type <filearea>/<name></bf> Look at a file in one of the fileareas
2415 Type out the contents of a file in a filearea. So, for example, in
2416 filearea 'bulletins' you want to look at file 'arld051' you would
2420 TYPE bulletins/arld051
2423 See also SHOW/FILES to see what fileareas are available and a
