[TenTec] Omni VII Query

[Val Erwin]

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.........
