Mike - everyone, 

Not that this will be of much help but for what it's worth I decided to run
a quick check on output power levels and thought I'd pass the results along
to everyone. I have the AT installed but checked the SWR along with power
levels while in bypass mode. 

160m - 99w   SWR 1.2:1 
 80m - 98w   SWR 1.2:1
 40m - 95w   SWR 1.1:1
 20m - 92w   SWR 1.1:1
 17m - 90w   SWR 1.3:1
 15m - 89w   SWR 1.4:1
 12m - 87w   SWR 1.5:1
 10m - 86w   SWR 1.4:1
  6m - 65w    SWR 2.1:1

The load being used is a Microwave Devices model 636N - with silver braid
coax &  silver connectors (from a professional radio shop).  The numbers
above were from a Drake MN75 but I checked with two other meters I have
available and all were +/- only a watt or two. 

Good luck and keep us posted after you talk with the Ten-Tec folks.

The plot thickens!

Looks like this one may have to make a trip back to the factory

Not only is the swr metering out of wack, but the total RF power  
output is quite low

on 40 meters with the power set at full bore, I get about 76 watts out.

14.0 volts, 22 amp

50 ohm load

NO band produces more than 80 watts output

While I know that there is +/- 10% power output, less than 80 watts  
is out of spec----especially for a radio that costs $3k
