[Elecraft] K3 sub receiver settings questions

[James Sarte]

Dear group,

 

I've been playing around with the sub receiver with a goal to SWL.  The way
I have my K3 set up is to have the general receive module on the sub.  The
main has a 13k, 6k, 2.7k, and .5k filter in FL1, Fl2, FL3, and FL4
respectively.  The sub receiver has a 13k, 2.7k, and .5k in FL1, FL3, and
Fl4 slots.

 

Now, when listening to the sub receiver, I've noticed that I cannot change
filter settings for the sub unless I go into B-SUB.  When I go into B-SUB
however, the audio level drops quite a bit, even though I'm still listening
to the sub receiver and the RF gain hasn't changed.  I'm not sure how to
best explain it, but you can definitely tell that you've gone to B-SUB mode
as the volume drops.  This does not change if the main receiver's RF and AF
settings match the sub receiver.

 

Is there a way to link the main receiver filter controls to the sub
receiver????  And what gives with the lowered audio signal when switching to
B-SUB?

 

73,
