P3

I've been asked a question that I cannot answer. Would the P3 work with a
KWM2 or 75S-1? If so, he'll buy one.

Re: P3

Phil,

I do not recall those transceivers having an IF Output.
If the KWM2 or 75S-1 is modified to provide an IF output, then the
answer is yes the P3 will provide a panadapter function centered around
the IF. The P3 will not display the operating frequency because that
information is not available.

I don't think so either, but I'm thinking it should be easy to tap off
the 455 khz signal path and bring it out to a BNC or RCA connector.

Re: P3

Tony and all:
I agree it should be easy to tap off the IF but I suspect that will be a
relatively high impedance point and will require a source follower (cathode
follower) circuit to drive the coax without dragging down the signal.
I seem to remember a QST article on adding a pan adapter to the KWM2 but
that was some time ago.

Re: P3

One trick people used to use was to wrap a wire around the mixer tube.
That picks up enough signal for the panadapter without having to tap
into the circuitry , which would likely require an IF re-alignment.

Gee, this takes me back - in the 50s you could pick off enough signal to
drive the Heath Q-multiplier by wrapping a couple of turns of insulated
wire around a pin on the mixer tube. Maybe the plate?
