With my learner's permit in hand, I wonder how you
tested output - CW... SSB ... or some more exotic
measure?
Also what is the error tolerance (+/-) of the meter, I
have read some have as much as 10% variance +/-
and if so, it could be that you are getting 95 watts out
and reading only 85 ?
Also, when you tested, what was the load - antenna, or
dummy load, or can/do you test at a point earlier in
the system? I am taking it that the "lab grade" 50 ohm
load is a high quality dummy load (i.e., a known quantity).
I am not being critical... just looking to learn and apply
a limited knowledge at this point.
Thanks.

Omni VII-ites'
I have an Omni VII that is appx. 2 years old. Over time, I have noticed a gradual decrease in RF output power.
With 13.8 VDC measured at the radio power connector, the Omni VII digi-panel states: "Power 100W". Yet, when the RF output power is measured with a lab-grade 50-ohm load and either a Bird 43 or a calibrated oscilloscope, the measured RF power is actually on the order of 85 watts output, regardless of band.
I suspect I have an aging component sitcheeashun'..........Is there an internal control to crank the RF back up to spec??
TNX in advance for any feedback.........
