OK, hard to say but that is quite the change in amplitude.? There
are other variables as the other guys have mentioned but the 250
hz drop out specifically is definitely indicating some kind of a
problem which could be the filter or something in the switching
chain.

Jeff-
?
I'm running a 29MHz test signal directly into the antenna
jack as a reference. I don't know the amplitude of the signal
but probably <1.0 microvolt.??
SSB filter - S8 on the meter
1.5KHz filter - S4.5
500 Hz filter - S8
250 Hz filter - does not move the S meter, audible above
noise floor but significantly quieter.?
