[Elecraft] K3 phones - separate left/right volume adjustment?

[Jim]

Well I did learn something today. Like many I waited until the 2nd receiver
was available adding it to my K3 and had not even attempted to use it for
dual receive split operation until yesterday. On 20 meters working the K5D
when I would turn the sub on I would hear an increase in noise & a rumbling
sound that was very distracting. I checked to ensure both receivers were
same bandwidth, agc, volume etc. Not figuring it out I contacted Support &
was advised to check the REF CAL & VCO CAL. This did not fix it.

Here was the simple solution that I stumbled upon that's in the menu, I
changed SUB AF from NOR to BALANCE.

Now all is well.

Not sure if you have the Sub RX but this may work if you do:

MCU 2.67 / 1.96, 11-12-2008

* MAIN/SUB BALANCE CONTROL:  If CONFIG:SUB AF is set to BALANCE,
then the SUB AF GAIN control becomes a main/sub AF balance control when
the sub receiver is turned on (including diversity mode). In this case the
MAIN
AF GAIN controls the AF gain level for both receivers. When SUB AF is at
12 o’ clock, both receivers will be at full volume (main left, sub right).
If SUB AF
is rotated fully counter-clockwise, you’ll hear only the main receiver. If
it’s 
rotated fully clockwise, you’ll hear only the sub receiver. At intermediate
settings
you’ll hear both. A BALANCE control is very useful for contesting and split 
operation. But it can also save a lot of AF gain control tweaking (i.e.,
matching 
main and sub), since MAIN AF controls both main and sub receiver audio.
