[Elecraft] K2 Receiver issues

[Don Wilhelm]

Bob,

Yes, the best and easiest way to determine what is wrong is to do 
Receiver Signal Tracing.  That should allow you to isolate the problem 
to a single stage and armed with that information, we can likely help 
better.

You do not need a 10 MHz crystal.  Any crystal frequency within the 
tuning range of the K2 will do just as well.  The 10 MHz crystal is 
suggested if you have no other - they are inexpensive and commonly 
available from a number of sources.

You will also have to build up an RF Probe (or use a 'scope).  The parts 
to build an RF Probe were included with your K2 kit.

73,
Don W3FPR
