I operated over the weekend as W6E as one half of a M/M HP County Expedition in
CQP.
I ran the SSB side of the show and N6MI the CW. Scott has the FTDX101.
We were both operating 500w into similar spec-ed 2 element beams on 20/15/10.
We were about 300-500 ft apart.
I’m looking for advice on how to minimize the CW thump thump I would hear when
we were both on the same band. It didn’t raise a HI SIG warning on the K3s but
it was audible enough to distract me especial if an adjacent station was
bleeding into my band.
#1) Buy Scott a better radio. Yaesu radios are notorious for being a
very bad neighbor. They're dirty, there's nothing another radio can do
when the other radio is spewing trash on your frequency.
#2) Study my talk on multi-station interference for many things you can
do with station building, antenna choice, feedline choice, antenna
layout,and the use of serious ferrite chokes at every antenna feedpoint.
Also see my detailed analysis of ARRL Lab tests of a selected number of
rigs. The raw data for my report came straight from ARRL Labs in
electronic form. Also see ARRL Lab plots of keying bandwidth and phase
noise for Scott's radio.
