[TenTec] Orion & Tune button

[Tommy]

Mark....

I think the process you describe is correct, but the numbers may be 
wrong.

For an Orion without an internal tuner, as you state, pushing the 
TUNE button is supposed to produce a fixed 20 watt output for tuning 
an amplifier. It's true that with the TUNE button pushed, you press 
PWR and the output goes to what ever you have the rf output power 
set for. 40 watts output in the TUNE position by itself, would 
probably overdrive most amplifiers, thus the 20w is a pretty safe 
level to tune up your amp.

Ref:  Manual page 19, Section (40) TUNE
