Since you're using CW, I think the only possible ill effect of the voltage
variation could be a pulling of one of the VFOs causing a chirp on your
signal, if the K2 voltage regulation isn't good enough to take care of it
(which it probably is.) The best way to be sure is just to listen to your
Key-down tuning for QRO is a no-no, as is RTTY. They spec the power
supply at 22 amps -- 25% duty cycle -- or 5 amps continuous. 12.5
volts times 5 amps is 62.5 watts. If one figures in the usual 50%
efficiency of transistor rigs, that's 31 watts brick on key, a figure
that will be need to set
What I don't understand is why they didn't double up on the cap,
upsize a few things and get it to 22 amps 50% duty cycle...
It should be possible to parallel another 5 Farad of C by adding a DC
connector to the Gamma supply. For higher duty cycle operations, just plug
the added C into the

Hi,
The Gamma is my primary PS on my K3 (don't own a K2). Never had a problem
with it since I've been using it almost a year now. That being said, you
have to understand its limitations: SSB, it's great and gets out 100w; AM,
reduce power down to 70w-80w; Digital modes some high speed CW can
