Ok...not familiar with your antenna but it sounds like you may have a RFI
problem. What happens if you turn the transmitter power way down or off. Do
you still see the same behavior?73,Gary K9GS

Corky;
1. You can shove some probes (needles or something) into the Anderson's
to check the voltage at the back of the radio.
Or pop the lid and measure at the circuit breaker terminal, but beware,
this is always HOT even with the radio turned off!
We recommend 1/2 volt or less drop at 100W TX.
Have you checked the 5.0 volt reference value In the CONFIG Menu at ADC
REF? See page 57 in the manual under CONFIG Menu for instructions.
This will/can affect things like rigs supply voltage.

I'm not sure where the voltage displayed on the K3 is sampled, but I have
found it to be consistently about a volt lower than the voltage present at
the Power Pole connector on the back of the radio, especially when in
transmit mode. I have found this to be the case on both the K3 I use for

Don, I am not sure exactly what "problems go away" means here.
Moving it to the separate power supply, cleaning the power terminal contacts on
the K3, and upgrading the power cable eliminated the brownout problem with the
K3. Increasing the voltage will certainly give me more headroom to play wi
