[Elecraft] Getting the sub to work on 20M

[Cady, Fred]

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,

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
