How do you do this? This field day, I found that having a station on SSB
in the same band with me when I was on CW was really problematic.
Antennas were oriented for minimal coupling and power was 100 watts.
Rigs in this case were various Kenwoods, but I've also experienced this
with other Japanese radios. The problem seems to be transmitted wideband
phase noise that starts when the ptt is closed (the actual SSB signal
does not seem to be a problem). We do have bp filters, but of course
they don't help on the same band.
We haven't had K2's at FD (I am the only one who has one). What kind of
rigs are in use at NQ4I?
