[Elecraft] Help with troubleshooting K2 receiver?

[Don Wilhelm]

Glenn,

Yes, you do have a problem. Either with T5 or the capacitors in the VFO 
Range Selection area or the Varactors.  See my post from your question 
yesterday.  If you do not correct the VFO range problem you will 
encounter difficulties later should you add the K160RX option and/or the 
K60XV option.
