I wouldn't be too quick to discount the K2's power measurement, Chuck. =
It's
quite good IF you have the rig connected to a good 50 ohm dummy load.
(Hooking it to an antenna or ATU with an SWR saying 1:1 isn't good =
enough.
SWR meters aren't THAT accurate).=20

If your K2 is showing normal RF output on the bar graph in transmit in =
to a
good 50 ohm load, that would take two completely different failures in =
the
K2 to produce the results you are seeing on the OHR: something wrong =
causing
low  transmit power and something wrong causing high power output =
readings
on the bargraph.

Help!  I just assembled my K2, and did the adjustments as best I could
without fancy equipment. =20
Recently I bought and assembled an Oak Hills QRP Wattmeter, and (to my
dismay) it shows that I'm running less than half the power I thought I =
was
on the K2 on all bands. (It varies from about 40% down to 20%, depending =
on
the band. I don't think it's the wattmeter.) As per the manual, I =
checked
the transmitter section, and the readings were OK except for the Q7
collector - 68 ohms instead of >500.=20
I'm kinda green on the technical side, so whatever fix is necessary has =
to
be step-by-step in the dark!=20
Thanks!
