We used to do that kind of thing all the time in the old days of tube-type radios. I used to keep an old Drake B-line around just for use on Field Day. It wasn't until the advent of solid-state fully-synthesized radios that it became impossible to do phone and CW on the same band on FD. The K3 h

I would try it. We had two K3's in use at the Holland (MI !) field day site, K8DAA on 20 meters. One on phone the other on CW. Sometime we were within 50-75 kc's , oops, kHz of each other, with no ill effect. The antennas were maybe 200 feet apart at the most, and they were not looking into

Craig, That may have been due to the wideband noise and other products transmitted from the other, non-K3, station. The VP6DX guys ran two K3s per band at 1500w for the complete time they were down on Ducie without interference. 73, Eric WA6HHQ _..._ Craig Rairdin wrote: I don't know a
