K3 AGC with Dual Receivers

[Chuck Guenther]

I've been using my trusty K3 for years with a single receiver, and
frequently experiment with AGC THR and SLP settings for best DX
reception.  As I seldom am in a position to "Run" stations, I have not
been bothered by what has been referred to as "pileup mush," except
perhaps when I switch briefly to VFO B to comb through a DX pileup.  My
main concern with AGC is to protect my ears, so I tend to use one of the
nearly flat slope settings. BTW, I really like the AGC action in my KX2.

I recently sent my K3 to Elecraft for installation of many
procrastinated hardware upgrades, including a second receiver. From my
reading of the manuals, I gather that I can adjust each receiver
independently, and can use different AGC settings on each.  Am I
correct?  If so, it seems like (for DX'ing purposes anyway) I might want
vastly different AGC settings for my left and right ears.  I am thinking
I might want one set of AGC parameters for optimum reception of a weak
DX station, and another set of parameters setup to listen to the howling
hordes in the pileup. Surely others have done this (if it is indeed
possible).  How does this work out in practice?

Thanks & 73,

Chuck,

If you look at the chart of CONFIG menu listings, all menu items that
have [SUB] indicated are separate settings for the main and the subRX.

There is no such indicator for the AGC parameters, indicating that those
menu entries apply to both the main and the subRX.

The AGC parameters *are* Tech mode entries, so you have to set TECH MD
to on before you can see them.
