[Elecraft] Not hearing signals in K2 with EC2 enclosure KPA100/KAT100 combo

[Don Wilhelm]

  Brian,

Do you have a BNC cable between the QRP antenna jack (or ANT1 of the 
KAT2) and the RF in jack of the KAT100?  That is where the RF must flow 
- RF does not flow on any of the lines in the AUX I/O cable.
