[Elecraft] K2 RECEIVER: WHERE ARE THE SIGNALS?

[Don Wilhelm]

Manuel,

If you can receive a signal with an antenna connected to C225, but not C226,
or 227, your most likely problem is improperly tinned toroid leads on L25 -
but check L26 while you are working in that area.

A quick check is to make a continuity check from the top end of C225 to the
top end of C227 - if you measure much more than zero ohms, the toroids are
not properly tinned and soldered.

73,
Don W3FPR
