[Elecraft] K2 SSB install with major oops

[Sean Cavanaugh]

Hi,

I was installing the SSB module in my K2 earlier this evening, and think 
I have majorly messed up the rig. I installed the SSB module per the 
instructions. While I was plugging in the K2, I brushed the chassis with 
the end of the connector which apparently was energized and blew the 
circuit breaker for the power supply. Once I fixed everything I powered 
up the K2, and it seemed to be working fine.

The next step was to verify that the CW mode was working fine. Well, not 
so much. Now a 599+20 on my FT-950 is barely audible, and there is no 
band noise when I switch the antenna. Since this step of the 
installation says to check everything if you don't get good results, I 
went over the SSB module and the reworked RF board to look for any 
problems and didn't find anything.

Just to check, I reinstalled W2, W3 and C167 and left the SSB module out 
and still could not receive any signals, though it had been working 
before. I also tried transmitting, and was getting no power out at 
all... my FT-950 couldn't detect the signal from the K2 transmitting 
into a dummy load a few feet from an antenna.

I think I've blown something up during my power connector misadventure, 
but I'm not sure what. I'll be replacing the power connector with a 
different one that won't let me blow stuff up. ;)

Any ideas on where to start troubleshooting?

thanks,
