Craig,

I am fairly certain that you will find an unsoldered connection. Those things can work for a year or more and then all of a sudden, the amount of oxidation begins to increase and you have intermittent operation.

Look in the genreral vicinity of the area where the tapping was more effective.

I purchased a pre-built K2 a couple of years ago.  It seemed to work fine 
except on occasion it would stop receiving, with a tap on the right side of the 
cabinet it would be okay.  These taps became more frequent.  I also noticed 
that the K2 would not transmit at these times.  Finally, about a week ago it 
quit.  Where should I look, or what should I do to get the rig back on the air?
Thank you,
Craig K9CKA
