Petr,
It sounds like the typical behavior when the receive antenna (RANT) is
set on - the setting is available on a per band basis.
Set the K2 to 20 meters, enter the menu and scroll to RANT. If the
parameter is ON, press the EDIT button and change it to OFF.
There is little else that can effect the receive sensitivity on a single
band.

Hi folks,
as my K2(sn:4800) is probably sick I would like to ask for help. I found
few days ago that on 20m (and maybe higher bands too) rx lost
sensitivity. No sigs and even ATU tunning a lot and much more hard the
same antenna.
First time it lost sensitivity only partly then even more often and now
for all the time.
I remember that few days ago when pb started helped sometime to touch
key when after dots comes sensitivity back. Now does not help anything.
When I switch to 40m or lower it sounds all good...
Thank You for tips to all,
73 Petr, OK1RP
