K3 AF Gain

I know I'm probably stupid and missing something obvious, but when I turn
on the sub receiver it is much louder in my right ear than the main is in my
left with the AF gain set the same on both receivers and both VFO's tuned
to the same frequency. RF gain is set the same on both receivers. I have
one antenna connected to ANT 1 (which then goes to KPA500 then KAT500).
The settings are as came from the factory and diversity is not on. I've
looked through the K3 manual and Fred KE7X's book and don't find anything. Is
this the 3 db attenuation when signal split to both receivers? I would
think the attenuation would be equal. Firmware is the latest. Sorry for the
bandwidth, it's probably something obvious. Thanks.

Re: K3 AF Gain

The AF Gain dial can also be used like a balance control. When you say
they are both set the same, what is probably happening is you have the
balance control over to the one side. Look in the Tech Menu for a
setting called SUB AF. The choices are nor and balance.

If you are in balance mode and you want them to be the same you have to
set the Sub AF Gain knob to the middle.

SUB AF is set to nor. I think I figured it out: the Noise Reduction was
set differently for each receiver. When NR is off for both the problem is
gone. I KNEW it was something stupid. Thanks. Sorry.
