Ken,
I notice something similar on my Pegasus with reduced RF gain.
My guess is it's some artifact of the DSP AGC implementing higher gain .
With no signal on my Pegasus (i.e. dummy load), numerous birdies are
noticeable. With real noise and signals, most of these end up below the
noise floor (though a few still remain).
73,
Mark

Subject: [TenTec] intermod on Jupiter when decreased RF Gain?
Dear Jupiter owners,
did anyone ever notice intermod when they lower the RF Gain? I
have been tuning around on 80M tonight with the RF Gain set to
only about 25% because of QRN crashes. I hear a lot of SSB, AM and
what I would call birdies - until I crank up the RF Gain to more
than 75% where everything is normal (but very noisy).
your thoughts?
