Hi Guys,

I have been dealing with a sick Centurion.  Still having problems.  I am going 
to rebuild the QSK board and try again.

However, when I was testing the Centurion with my Orion 1, I had keying loop 1 
connected and it was working….for a short time.   Something happened when I was 
testing and suddenly the amp would no longer key.  I think the problem lies in 
the QSK board.  I’m sure something failed there again.

But, when the amp stopped keying, so did the radio.  If I have the keying loop 
turned on, the radio will not key at all.  If I turn the key loop off, the 
radio keys fine.  if I turn on keying loop #2, the radio keys fine.  So the 
radio keys fine except when I have key loop 1 turned on in the menu.  

So my question is, have I damaged keying loop #1?  If so, what do I need to do 
to fix it?

thanks for all of the expert advice!
