For those who don't know,
I absolutely cannot upgrade to the latest P3 FW (1.25). I had similar
issues with 1.24, but it eventually loaded after several attempts.
I have tried about seven or eight times and it always gets to the same

This morning I removed the entire shack from AC and left only the K3/P3
on battery and the antennas disconnected. No change on the screen. Bunch
of work for nothing and was exactly what I expected.
Of note: The ghosts vanish when the band is active - covered by the
ambient background noise
An update:
I have tried different USB ports on the computer and a different cable.
I cannot use a true RS232 cable as I have no true RS232 port.
So, I don't know if the P3 is fully loaded or not.

I fought the same problem Dave W8FGU had and also tracked it to the cables for

was no tension in the connector when seating them and thus there was eventually

Just bought one of these boom mic-headsets and plan to use with my K3's.
Is the battery bias supply included with the headset needed?
And do I need to adapt the microphone's 3-conductor mini phone plug to a

Thanks any help
Jon,
Just plug it in, turn bias on and set the Mic gain range to L (low) -
the microphone is quite sensitive. (MIC SEL RP.L bias)
You do not need the battery on the K3, but hang onto it, you may need it
with another transceiver that does not supply bias internally.

It sounds like you are having a problem with your USB/Serial Adapter. Make sure

A signal near the I.F. that is picked up by the P3 or P3 cable will not move
as you tune.
Other signals appear to move only because their frequency relative to the

Thanks Ron - great explanation.
This afternoon the desk comes out from the wall so I can get behind
everything and I will try a few more tests and cable replacements. At
least I will know if it is internal. Slow process and easier to just
ignore - but I'd like to know where it is coming from.

The thumb drive is plugged into the USB-A connector on the back of the SVGA

The P3/SVGA manual will be updated shortly.

The K3 is one of the highest-performance radios available (very high

I see no reason it would not work. If the amplifier presents a good 50
ohm load to the exciter, then I would suggest you forst tune the KAT2
into a 50 ohm dummy load for ANT1. Connect the amp to the ANT1 jack
from the KAT2 and it should drive the amp just fine.

The combination of mouse-based point-and-click tuning within the stable
