[Elecraft] K2 SSB install with major oops

[Sean Cavanaugh]

Thanks to all who replied with suggestions. I traced the signal and 
found the problem. Turns out to be user error... I have the K60XV module 
installed using BNC connectors on the top cover. Well, when installing 
the SSB module, I removed the top cover and hence the K60XV, but didn't 
bypass it breaking the connectivity through the BPF. I put the module 
back in and everything is working correctly. I was worried for a while, 
but now my baby is working again.  :)
