Tap DISP {8} and use VFO B to show time, supply voltage, etc. on VFO B (pg.

I have a factory built K3 (s/n 3668, Nov 2010) that has developed a problem.
Looking for suggestions or remedies.
For the past year the radio will occasionally have a fluctuation in power
output. I will be transmitting on CW and the power will suddenly jump to
120+ watts out. Then it will dro

Bill,
Does this occur on a dummy load?
Tell the K3 to monitor the supply voltage and check what happens when you
transmit.
Do you have a new antenna, or has the possibility of RF feedback increased?

Hi Bill,
Have you set the power to 30 watts and then switched to another band? Power
levels are saved on a per band basis if you have set CONFIG:PWR SET to PER
BAND.
Are you running some PC software that could be sending power level data to
the K3?
Are you connected to a KPA500 amplfier where th

How do you tell the K3 to monitor the supply voltage? I checked the
owner's manual under voltage and meter - nothing there. Same for the
Cady manual.

Hi Bill,
Very simple. See page 36 of the manual under VFO B Alternate Displays. Here
are the two steps required.
1. Press the DISP button
2. Rotate VFO B knob until the voltage is display on the bottom display
Press the DISP button again when you want to go back to monitoring VFO B
frequency.

Hi Randy,
It sounds like you need to do a transmitter gain calibration. See page
49 in the manual in the Calibration section.
The procedure in the manual will work fine but the K3 Utility automates
the process to the point of being fool-proof.

Adrian,
The power cable in good heavy duty type wire.
The power supply is also a good solid heavy duty supply.
Have also switched the PS and get the same results.
I do not have a P3.
Thanks for your input. Looking for all the h
