I think that voltage must be an indication that the transistor oscillator
is at least drawing the right amount of current through R9. I'm going back
to recheck all my work on the default output attenuator.
No, sorry - I meant that in the 50uv position it generated an S9
reading. In the 1 UV position it was easily audible, but no S meter
deflection at all.

It reminds me of methods to receive weak signals with other radios. Adjust
crystal filters for a single peak, reduce RF gain, play with ATT K3

All what K3 needs for NR (and NTCH) is to put them inside the AGC loop, like
for instance in IC7000.

I don't think that should be a problem. The crystal has only 2 leads,
so if you can pull it a little while heating up one of the leads, the
end you are heating will break loose. Do the same with the other lead
and it should come out painlessly. Then clean up the holes in the PCB.

To remove the crystals, first clip off the ground lead. Then most
likely you can heat one of the pins while putting a bit of pressure
against the side of the crystal. As soon as you feel it move, heat the
other pin and repeat. It will get easier after 2 or 3 passes, and you
can get

The K3 audio channel is designed for communications audio in a bandwidth
of 5 kHz or less. There are a number of reasons for this.
Using the 13 kHz roofing filter doesn't change that. It does widen the

signals. Think of
