[Elecraft] Did I fry my KXPA100?

[Tom]

Hi,
No, I didn't.
However, it seems that the amp is not blown.
I have no idea what's happening...

Ok, Elecraft recommended a TX Gain calibration.  That was successful on all 
bands.
I changed all the RF cables and the KXPA100 still shows no output...

However, this was on 20m.
If I switch bands, the KPXA100 is working fine on all other bands.  It just 
so happens that this seems to happen only on 20m.
Everything looks the same as far as I can tell, same antenna (all testing is 
into a dummy load)
So it is only on 20m.
What have I missed?

Thanks, Tom

Tom,

Did you connect the KX3 Keyout signal into the KXPA100 PA KEY input?
That is necessary for 'Basic Operation' - see page 18 of the manual.
