I think the first thing to do is to check the watt meter.
Either borrow another watt meter and compare, or try a different
transceiver.
If a second transceiver reads the same or similar, then it's the watt meter.

Hi Rick.
RF power measurements are taken both into dummy load and well matched
antenna (SWR=1.2) . Power supply voltage at back panel connector is 13.95V
key-up, and 12.85 key-down on 10, 12.75 on all other bands. More current
being drawn at the higher power outputs. Voltage measurements taken on a
Fluke 8060A meter.
You bring up a good possibility Rick. I am reading the power output on a
TenTec 1225 wattmeter which I have not calibrated in a long while, so I do
need to do that. However, the power meter on the Orion does read 100 (full
scale) on all bands except 10 and 15, where it reads about 75 % of FS on 10
and 85 % on 15. While these may be pretty close to actual power readings, I
just take these to be values relative to FS.
Tnx es 73, Art
