Note that the first filter has not been specified with a number. This will automatically be assumed to be number 1. In this case, we have said reject all HF spots in the CW section of the bands but accept all others at HF. Also accept anything in VHF and above spotted in or by operators in the zones 14, 15 and 16. Each filter slot actually has a 'reject' slot and an 'accept' slot. The reject slot is executed -BEFORE the accept slot. -
