P3 Panadapter while transmitting

I have a K3 with the P3 Panadapter and I notice that if my ESSB is OFF and
I transmit and then turn on the P3 I can monitor my audio bandwidth at the
correct center frequency..... Audio playback works great for this - giving
me plenty of time to re-boot the P3 during the K3's transmit.

However if I enable ESSB this is no longer the case. The signal is no
longer where it should be - does anyone know why?

It would be nice if the experts at Elecraft could work into the K3/P3
firmware so that we could monitor the transmit audio instead of the P3 just
freezing!!!

Thank you,

Re: P3 Panadapter while transmitting

I do support the demand that Elecraft should reconsider the K3/P3 control while transmitting.

My recent posting "[P3] Display freeze during CW keying" does address the same deficiency.

The addition of a P3SVGA would make no sense before the reported imperfections are fixed.

Hopefully the P3 will remain a fully usable 1st class Spectrum Analyzer instead of becoming an All-in-one device suitable for every purpose (in german: eierlegende Wollmilchsau).

Currently a missed opportunity...

Unless/until Elecraft introduce a separate RF sensor for the K3/P3
monitoring during transmit makes absolutely no sense. The IF output
*is not valid in transmit*. It does not accurately reflect the RF
output, it is offset to the actual transmit frequency and any signal
is the result of random coupling in the circuit.

Although the P3 might make a pretty picture in transmit, the picture
is not worth the electrons it takes to make it.

The P# is not a "fully usable Spectrum Analyzer" ... it is a limited
function "panadapter" (narrow range spectrum analyzer - dedicated to
the transceiver IF).
