[TenTec] Centurion and AM

[George Fritkin via TenTec]

I am sorry, for some reason I was thinking Centaur!!!!

The Centurion, I got it right this time, does it in a breeze.  

Looks like hot weather got me too.

Nothing wrong with this as I am one that did exactly that with no issues.  There is a duty cycle rating that needs to be followed but everything else works.

However if you are using low level AM from your xcvr you probably won't get 100% modulation so it might not be a problem. If it were me, I would drop the power to 150 watts to be safe
