[Elecraft] BFO Test fails

[Don Wilhelm]

  Name and call please - now required by reflector guidelines.

I assume this is a K2 - although you did not state it, it only makes 
some sense with the K2.

Is the internal counter probe working?  What do you get when in CAL FCTR 
if you plug the probe into TP3 or TP1?

The BFO frequency of the K2 should be near 4915 kHz.  At U11 pin 6, the 
BFO signal should be at least 200 mV peak to peak (70 mV RMS).

73,
