[Elecraft] K2 - No Signals on 7MHz Band, All other Bands OK

[Don Wilhelm]

Mark,

"No signals on one band" usually means that you have the RX antenna 
selected - a quick check can be made by putting the antenna on the RX 
Antenna jack.  If it is set on, the menu for RANT is what you are 
looking for.

The ANT1/2 selection is also per-band, so check that as well.

If those do not fix it, go to the secondary menu and check the setting 
for D19 - you do not have the K60XV, but if you installed the rework 
eliminators, you would have changed C71 - with rework eliminators or the 
K60XV installed, D19 must be set to "Y" - without either installed, D19 
must be "N".

73,
Don W3FPR.
