[Elecraft] KRX3 delivered - KRX3 Problem

[Phil & Debbie Salas]

"... Installed: 12 August 2008 but horrendous problems!  K3 has ceased to 
function..."

I had a problem with the KRX3 as well.  With the KRX3 installed, my K3 audio 
was completely silent, and the K3 would no longer transmit.  I emailed K3 
support, and they told me to check everything, especially the cables and 
also re-run the VCO cal.  This didn't help.  So, I disconnected everything 
easy and the problem was still there.  Finally, I opened up the front panel 
and removed the aux-DSP board (I did this last as it was the most difficult 
thing to do).  Once that aux-DSP board was out, my K3 was back to normal.  I 
reconnected the KRX3 completely and everything still worked fine (of course 
the KRX3 wouldn't work without the aux-DSP in place).  I emailed K3 support 
with my results and they sent me a replacement aux-DSP board.  I installed 
this, and now everything seems to be working OK.
