val...

brand new out of the box, my omni VII NEVER did 100 W into a  
calibrated load/wattmeter

about 85ish is all she'll do

that's been two years and RF power output is still 85 watts give or  
take a few.

my biggest complaint is the SWR meter is just about useless. if the  
swr on the transmission line varies just a bit off of 2 to 1 then it  
shows 9.9 to 1.

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.........
