With electronic log submission easy to enforce, just invalidate any QSOs by W/VE run stations in the window. That's not practical to enforce via logs because some participants may be using radios that have no connection to the computer other than the key line. 73 Charlie, N0TT

Carol, N2MM Rule 6.1 for the ARRL 160... The segment 1.830 to 1.835 should be used for intercontinental QSOs only. Note that it says should be. IMHO, following the suggestion just makes the contest more fun for everyone. Charlie, N0TT On Sat, 1 Dec 2012 00:54:30 -0500 Carol Richards

I can only figure one possible how someone is exactly on PTOS Fx and repeated keep calling directly on the DX Transmit frequency and that is that they have their radio set split and then reversed it while still listening to both frequencies simultaneously. This way they would hear the DX
