My understanding is the KAT500 will overcurrent the K3 Aux DC output.
The KAT500 specification is 1.5A max (200 mA typ) from my IB (page 2 Rev B3
Nov 20, 2012. The 200 mA should be ok but the 1.5A is greater than the K3 1
amp mod is rated for.
I power my KAT500 from my station power supply.
My ancient Prolific USB to serial converters have been ported from XP to

They work flawlessly - both versions of Windows installed the proper drivers

You might uninstall the USB converter, unplug it, reboot and then

Condenser Dynamic microphones can both be used with a K3 or KX3.

Bias is added to the tip via menu.
The voltage you read on the 1st ring is the pull-up for the PTT UP/Down

David - Those are very good reasons to keep UHF connectors.
The impendence mismatch of UHF is probably far less than the other

Not to mention that BNC come in 2 flavors - 50 ohm 75 ohm. A 75 ohm BNC in
a 50 ohm system will have a far worse mismatch than the worst
Last week (Monday) I left a message for a replacement VFO B knob for my K3 @

The reply from a technician about an hour later was that the order had been

confirm that was what I actually needed.

Mark,
My understanding from the manual is that the KAT500 must be on when the K3
is turned on for the Aux connection to work properly.
In my shack this is accomplished by connecting the KAT500 directly to the 12
volt buss; that way it is already on when I turn the K3 on. This works well
for me.
I know we don't vote on this reflector; but I would prefer the Default FW
load to be as is now so it matches my manual.
Personally I do not use Link/Unlink!

My observations:
The K3 is delivering only the KPA500 drive level power not 100 watts. So at
least the K3 thinks it is driving the PA in operating mode. The KPA500 has
only the first one or 2 power leds lit.
The PA has the *. I think that indicates key is being generated.

I might tend to agree with you had the P3 control been labeled WIDTH!
But it is labeled SPAN.

The P3 is more of a kin to a spectrum monitor but
My Got Ya:
One part of the learning curve that I discovered is that you must turn on

On my desk it was just more logical to turn on the KPA first and while I was
there to press Oper. I Then had to figure out why I
I was under the impression that the KAT500's form factor was P3 size.
Since I already have antenna switching the way it needs to be with still
about 30% growth built in, I would prefer the tuner be small enough to
stack onto my P3.
I doubt that could happen if it included a high power RF routing

I use macros for PF1 PF2 to switch between the front rear microphones.
