[Elecraft] K2 deaf on 30m and 12m

[Don Wilhelm]

Werner,

Since there is no relationship between 30 meters and 12 meters in the 
hardware, then I suggest that you first check the RANT menu setting for 
those bands.  Problems like this are usually the rresult of 
inadvertently setting RANT (receive antenna) to ON for the bands that 
seem 'dead'.

Just for those who are wondering, the 30 meter bandpass filter is shared 
with 20 meters, and the 12 meter bandpass is shared with 10 meters - if 
there is a hardware failure, both bands would likely be affected and 
both transmit and receive would fail.

73,
