[Elecraft] Using the Sub Receiver

[Bruce Sawyer]

Apologies in advance if I am misusing this reflector.  I just joined it a
moment ago in an effort to get some help.

 

I recently upgraded my K3 by adding the sub receiver to it.  I built the rig
myself, then used it for 5 months without the sub receiver, and just last
week had the sub receiver installed and tested by Elecraft.  That gives me
some confidence that it should be working.except that I absolutely cannot
figure out how to use it.  Initially I tried to use it the same way I did
the sub receiver in my old FT-1000MP, but I can tell this one doesn't work
that way.  If I simply tap SUB, which is what I would have expected, then
the VFO B knob has no effect on what I'm hearing through the right
headphone.  The only way I have been able to get the sub receiver to behave
like a sub receiver has been as follows:

a.       Set CONFIG:VFO IND to YES.  Then set VFO's A and B to different
bands.

b.      Tap SUB to turn the sub receiver on, then press and hold SUB to put
it into diversity mode, then tap SUB again.

If I do all of that, then I can hear a different frequency in each ear and
the VFO A and VFO B knobs are respectively controlling the frequencies of
what I hear in each ear.  But that is nonsense!  I have not been able to get
the rig to do this when both are on the same band.  What I want is to have
both VFO's on the same band so that I can listen to the calling station on A
and tune around on the pile-up with B,  all the while being able to hear
both frequencies.  How do you do that?

 

It is slowly becoming apparent to me that VFO A, VFO B, and SUB are three
different things.  I guess what I'm really asking is how do I get the VFO B
knob to control the frequency of SUB?  I have practically memorized pages
37-38 of the user manual and it's still not coming through for me.  Help!
