Put the 20 m antenna, not the dummy load on the rig. Then look at the
output SWR on 20 when the power is low. Let me know whether the SWR is
normal or high.

Subject: [TenTec] omni 6+/ power issue
My OMNI 6+ has a power issue on 20m and 17m, it drops to 50w output on 20m
and
15w on 17m. All other bands are okay. I've checked the output of the L.O.
Mixer
board, port 26, across a 50 ohm load. 160m through 40m, the the output is
800
mvpp and and drops to 100mv on 20m and up. I don't think it is the output
filters of the PA because 20m and 17m don't share the same filter. The
L.O.
Mixer is nested below another board so I can not make any measurements on
that
board other than ohm meter readings. Has anyone seen this before?
Thanks,
Wayne/w8aju
