Disabling the AGC in the K3 certainly does "do the trick" in terms of
preventing strong signals in the passband from reducing receiver gain
and thus affecting the weaker signal I'm decoding - that's exactly why
I do it.
As for ADC overload -that's a risk I'm well aware of but most of the
time it's
Bob,
That will do the trick in an analog only receiver, but a receiver like
the K3 has an analog front end followed by an ADC and DSP processor.
The trick is to keep from overloading the ADC - should that happen, the
copy will be garbage.
That situation is not limited to the K3 - overload of
I simply disable AGC when I wish to run a wide receive bandwith with
PSK31 for "point and click" tuning - precisely to avoid such a
problem.

Thomas,
I will not answer your questions directly,
BUT
From an operational standpoint, using a wide bandwidth for data modes
is *not* the best way to do it.
The reason is AGC in the radio. Any signal in the receiver passband can
activate the AGC - and that is fine *if and only if* the stronges
This is the current state of the radio :
the 6 khz filter is in FL2, the 2.7 khz filter is in FL3. ESSB is on, and set

USB/LSB is used (note that it is off during DATA modes). AM TX is set to FL2,

I have been using several programs (Cocoamodem, mostly) to do PSK31, via Data
A. Instead of being able to use the full 4khz waterfall bandwidth available in,
say, Cocoamodem, I have been limited to the available width in the only filter
I had in the rig, the 2.7 khz 5-pole appeared to limit me
