20M sub receive

On 20M the Sub receive dose not work.On all other bands when I turn on the
Sub I can hear signals on VFO B. When I try on 20M it is dead.I have turned
the VFO A down so I hear nothing there and the B full volume and there is
nothing.
Where would I look to correct this problem.

Re: 20M sub receive

Check antenna and filter/NR settings for Sub ( use "b Set").

Hi Jay,

The most common explanation for this problem is incorrect antenna assignment on that band. The K3 remembers your selection per band so it is possible that one band might have the wrong assignment.

In a like manner other parameters are remembered per band such as filters, NR, NB, ATT or PRE, etc..

Re: 20M sub receive

Also make sure your (contest-logging?) software is not causing the problem.
I had a spell, when for reasons I don't completely understand, SUB wasn't
working on forty meters. By chance I disconnected N1MM, which was in SO2V
configuration, and the problem went away. The problem had something to do
with conflict between N1MM and a homebrew external switching scheme.
