Ken, That sounds like something did not get properly soldered, but was making marginal contact until now. Look for it on the KSB2 board and/or its connectors to the RF board for the most likely place. You may want to just reflow the solder joints in case there is one that moved on you while it was cooling - such cold solder joints are often difficult to spot visually.
As a second thought, what kind of antenna are you using? If you are experiencing 'RF in the shack', that can cause a myriad of strange things to happen. 73, Don W3FPR > -----Original Message----- > > Murphy's law struck down K2 #4913 today. :-( > > I was taking pre-net checkins for the Central States > Traffic Net (7.253.5) when I started getting reports > as if I had a bad antenna connection.
