[TenTec] Help Understanding the Herc II Overdrive Light

[Eric Rosenberg]

Just put the station back together in time for the start of the 10m 
contest.  I've run into a couple of quirks with HERC II that I  had 
forgotten about.  I am baffled by the Overdrive light and bar graph.

Overdrive:
With power set at '49', the peaks out of the amp are ~360 watts on on RF 
Applications VFD digital watt meter.  That's approximately where the 
overdrive light goes on.  The signal doesn't seem tp be distorted -- at 
least it doesn't sound that way on the monitor and I've had no reports.

Bar Graph:
I realize it's impossible to compare the VFD when operating SSB.  Key 
down (TUNE and CW), the bar graph shows far more power than the VFD 
does.  Any way to calibrate or reset or correlate the bar graph?

Thanks + 73,
