With my K3/KPA500/KAT500 combo I occasionally get a soft or hard alarm on the
KPA500 due to the K3 briefly giving a high power burst.
I now have a digital peak power meter between the K3 and KPA500 and I can
see the surges.
The power output from the K3 is steady apart from these brief bursts. The

The K3 KEYOUT can handle up to 200 volts as long as it is a positive

Jim,
Just assign each transverter to a unique TRN address number. The XV144
can be TRN1,2,3, or 4 depending on the setting of the DIP switch inside
the XV144. The internal K3 k144XV option is INT TRN1.
I don't have either the internal or external 144 transverter, so I

I see both a sine wave and a square wave version available on ebay. The

Initially, I'll only be connecting a K3, is one a better choice than the
other?

Doug,
Many do not understand what how K3EXREF improves accuracy and
stability. Its commonly thought that its a phase locking system
(which it is not doing).
Basic frequency accuracy and stability is established by the TCXO in
the K3 which provides frequency reference to the VFO's. Per
Bruce,
The bottom line is that the BFO frequency is 'drifting'.
The most probable cause is a defective solder connection in the BFO area.
Carefully lift L33 and reflow the soldering of the BFO crystals. Reflow

The "end user" symptom was and is that filters would over time "drift"

Sorry about that. I'd be glad to help you. You can email me off-line

Hi Rich,
Do the TX Gain calibration again and then retest into your dummy load on all
bands. You don't need to use the amp or tuner since it's a K3 problem that
you can see with your power meter.
You indicated that the overshoot occurs on the lower bands. If it only
occurs on 1 or 2 bands you
