With his permission, I'm forwarding the following message I received today
from Michael Tracy, KC1SX, of the ARRL Lab. I call your attention in
particular to the expanded test report for the IC-756, which includes
spectrum analyzer displays for several other radios.
Can one of the more technially-versed among us comment on how well this
test characterizes the "clickiness" of a given radio? Should a test also
be run using split frequencies, to check for synthesizer issues? Or RIt on
I'd be interested to know how the FT-1000MP, FT-1000D and Omni 6+ would
compare under comparable conditions.
