[TenTec] Orion problem

[K9RT at aol.com]

Well it has finally happened. First problem in an otherwise flawless  
operational Orion classic..
My Orion receives fine, keys fine BUT no rf reaches the SO239 on the back  
panel and the keying line also won't key the amp. Panel meter says it is  
transmitting etc.
Have triple checked everything I can think of. Last time it worked  
flawlessly the day before with no hint of a problem.
Have turned it off an on several times with no improvement  noted.
Only thing I haven't done yet is a full reset.
Any suggestions before I do that would be most welcomed. Hate to do a reset  
due to having to reset all parameters but will do so gladly if that is the 
next  sep.
Thanks
