Getting the sub to work on 20M

K3 & sub Rx installed.

I rarely use the Rx antenna on the upper bands but today went to work
TN2T on 20 SSB to work split and discovered I don't hear anything Rf
wise coming from the sub Rx. I have no problems with the sub hearing
independently on the other bands & used it to find the right split on
10M & it works fine on the lower bands, seems like it's confined to
20M.

Any ideas if there's anything I can check to see if it's not set up
right?

Thanks,

Gary

Re: Getting the sub to work on 20M

I've looked through the manual (PDF version & searched memory and
antenna & sub) and I can't seem to find anything that helps me in
this problem.

When I go to B Set to configure the sub Rx when I'm on 20M, nothing I
do gets the sub Rx to work regardless of the antenna I'm using. I
hear a loud hiss but nowhere do I get Rf with the sub on 20M. All
other bands I do.

Anyone have any specific suggestions what I can try to get the sub
working on 20?

Thanks

Re: Getting the sub to work on 20M

Hi Gary,
Sure sounds like the sub receiver is using a different antenna than the
main when on 20 meters. The antenna configuration is kept on a per-band
basis so it could be different on 20 than on the other bands. What I'd
think I'd do is tap A>B twice to make sure all the filters are the same
in each receiver (maybe try some different filter width settings to make
sure something hasn't gone wrong with the sub rx's filter
configuration). Then make sure the sub is using the same antenna as the
main. In B-Set, tap ANT to select ANT1 or ANT2, which ever is being used
by the main. If not in B-Set, holding RX ANT will show MAIN or AUX for
the sub rx. You want MAIN.
That's about all I can think of.
73 and cheers,

Did the VCO calibration on the Sub receiver go OK?
