[Elecraft] K3 - No RX/TX

[Alan Sewell N5NA]

I had a similar problem a month or two ago.  I had upgraded my 
synthesizer back in February.  It turns out I had not fully seated all 
of the TMP connectors on the new KSYN3A.  It worked great for months, 
even running mobile for several QSO parties, before I had the problem.

So, check those TMP connectors on your synthesizer board.

73, Alan N5NA
