Nope. The key inputs of both amps are buffered. Partial schematic of

Not a great choice. SWR gets increasing nasty above 15M because the
construction uses chassis as signal return rather than carrying it on
the circuit board. It's a two-sided board, but the "ground" layer is
broken under the traces that carry the RF, so return current can't flow
on that layer. I

So the different voltage sources from each amp do not bother each other when
connected together with a Y or was only one amp turned on at a time?

From my formal training in audio tech, a 10 dB gain is needed to get a
perceived doubling of audio. With an audio sampler device listening for volume

Your settings should look something like this:

Power - 50 Watts looks good

12900kHz sounds like a proper frequency for the PLL Reference Oscillator

Mike,
No matter what you do, make certain the TXD and RXD lines have only one
driver on them. That would be the driver in the K3 and the other in
your computer.
Configure any other gear to "listen only" to the traffic between the
computer and the K3/P3.

The mics work. My problem was a burst of noise when the rig went into

It appears re-seating the USB cable in the back of the radio has cured
the problem. It did not appear to be lose. And the noise would appear

It sounds like that noise is coming from whatever computer software
