[Elecraft] K2 BFO Test fails

[Don Wilhelm]

  Benny,

Additional thoughts - check D38 for correct orientation.
Try putting a jumper from the junction on L33, X3 and X4 to see if you 
get oscillation at 4915 kHz or something close to that frequency - if 
you do, the crystals are OK and your problem is with L33, D37, C169 or Q24.
