K2 deaf on 30m and 12m

[oe9fwv]

hi all,

I am back from a trip to Panama and the K2 did a good job especially on 40
and 20m, had S7 contacts to Europe with 10W.
But I also found out that the receiver of the K2 is deaf on 30 and probably
also on 12m band.  Transmitting seems to work fine, I can measure full
output on all bands.
Where should I start to search?

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.

Don,

as usual, you are perfectly right.
the RANT was on, and no antenna connected.   blush....

I'm not a complete idiot - several parts are missing.
