[Elecraft] KDVR3 installed now no RF power

[Dick Dievendorff]

You're sure that CONFIG:KPA3 is "PA nor"?  Perhaps you changed CONFIG:KPA3
when you enabled the KDVR3?

Subject: [Elecraft] KDVR3 installed now no RF power 

I installed the KDVR3 to #191 last night and it appears to work fine 
(enabled in Config) but I now have very little RF output when connected 
to a dummy load. The 100w PA doesn't appear to kick in when the power is 
increased above 12 watts and there is no power output showing on the 
meter at all.  The ATU relays click when activated but no SWR value 
appears.

I'm using the latest firmware and have double checked that all the pins 
lined up when I reassembled the front panel.   At the same time as 
fitting the KDVR3 I incorporated the speaker amp mod, front panel mic 
mod (ground pin 7) and the keying rise time mod.  After each of these 
were done I checked resistance as per instructions and all appears fine 
there and I feel confident that I didn't damage anything else while do 
these mods (famous last words!).

Any advice would be gratefully appreciated about where to check next,  
later this evening I'll remove the KDVR3 and see what happens.

TIA & 73
