[Elecraft] K2 freq. counter

[Don Wilhelm]

LS,

That test is *only* to test the functionality of the counter probe - the 
reading will always be close to 4 MHz.  Do not be concerned about the 
exact reading - if it reads FAR from 4 MHz, that is a problem.
After you have the K2 fully assembled and want to do a good job of dial 
calibration and filter alignment, that is when you need to be concerned 
about setting the 4 MHz reference properly (may not be exactly 4 MHz).  
Use the procedure and tools that I mention in my website article on K2 
Dial Calibration - www.w3fpr.com.

73,
