In RTTY contests we can define the 2 receivers as 2 different radios (2
instances of K3 in ports using same com port) I have not heard of anyone
doing this in any other mode and certainly not in mixed mode. But it might
be possible for the WriteLog code to be updated to allow this. Doesn't
happen
My guess is that there is something in you're bandplan settings in the HRD that
causes this behavior.

Update on my low output issue:
I ran the TX Gain Calibration this morning, and everything passed with
flying colors.
I am seeing about a 4-4.5V drop across the radio when going from rx to
tx. Rx voltage sits at 13.8V, but when I transmit, voltage across the
rig drops to between 9 and 9.5V.
One other thing I forgot to mention in my last post - when I change
bands, I get the message GEX on the display of my K3. I can't find a
reference to that message in my K3 owner's manual, Fred Cady's book, or
the Elecraft web site. Can anyone shed any meaning on what that message
means? I'm

I figure you have the blue bodied trimmers and not the older ceramic ones.
Look at them carefully - one end is rounded (that will be the wider end
with rounded corners) while the 'shorter' end has angular corners and a
flat between those corners. That is the 'flat' side and should be
Using a DVM or other self-contained voltmeter, measure the voltage at

Wow. That will certainly explain the drop in RF power output.
I would not suspect corroded pins on the KPA connectors since resistance
there will limit the current the PA can draw and actually reduce the voltage
drop.
Are you looking at the voltage reported by the K3's display? If so, can you

Hello again,
A simpler way that would only involve changes to the KAT500 utility would to
have the utility talk to both the K3 and the KAT500. Even if the K3 is
already busy talking to a logging program, LP-Bridge unmodified can fix that
conflict. So now we have just created more work for Dick.
LP-Bridge alone will not help. While K3 Utility can obtain the
frequency information through LP-Bridge, that information would only be
sent out the same serial port back to the K3 - nothing gained. Remember
that the KAT500 uses a different serial connection than does the K3, so
