We never saw this at J6 and the pileups were huge. Are you certain that
the radio is not broken in some way? G0DVJ said the K3 was very
impressive in its ability to handle the huge pileups and crowded
conditions. He is probably going to be purchasing one.
Are you using the noise blanker by chance? What is the build out of
that radio. Was this a multi transmitter operation? If so could it be
the other radio is trashing the K3? We used NQN bandpass filters and
never heard each other. Are you close to any high power AM broadcast
stations? Does this happen on all bands or just some?
Many times I had to crank in the filters to widths that other radios
could not possibly handle and I worked my way back into my main pile
picking out calls one at a time. The audio was always crystal clear.
If the K3 can't do it , no radio can. Maybe the FTDX5000 but it is not
a radio that can travel. The TS-590 might if they had bothered to offer
roofing filter options.
