Think it was indicating HIGH actually. If I remember right, set at 5W,

Nick,
In your original probelm description, you did not state how much power the
K2 display was indicating - and I would tend to believe it indicated that
the power was near the requested power value.
Of course, the actual power was not that high, but since the base K2 uses an
RF probe type detec

OK, this is kinda annoying, and kinda good news.

Nick,
Read that paragraph with the undertanding that the most important shared
circuits are the PLL Reference oscillator, the VCO, and the BFO stages - and
they are also measured with the RF Probe even for receiver testing - the VCO
and BFO should also be tested for correct frequency using CAL FCT

That's what I figured... or something confusing the power meter into
thinking it's kicking out far more than it really is (EG set to 5W, it

Jim,
Of course you are correct - Nick did not mention that he had the ATU
installed, and since it is a newly built K2, I ASSUMED it was not - shame on
me!!
If the ATU is installed, pressing TUNE and DISPLAY at the same time will
produce full power output.

Don and Nick,
Doesn't the K2 drop the power to 2 watts during tune? Or am I thinking
of a K2 with the ATU?
I know that I was bitten by this once - I thought something was wrong
with my K2 when I was
trying to tune it up with a new antenna and I had a power meter in
line. I had set the K2 to
Nick,
With both low power out and low current drawn, there is clearly not enough
energy being developed by one of the transmit stages.
If you have not already, build up the RF Probe that came with the K2 kit and
do the Transmitter Signal Tracing steps detailed in the Troubleshooting
