Something like that (a glow-in-the-dark trim ring for the tuning knob)
could actually be useful on the KX1. Just the thing to make it easy
to find the rig in total darkness without putting additional drain on
the batteries.

Hi Rich,
You could control 12 V to an external RX antenna or preamp using the

during receive, and goes to 0 V (ground) during transmit. The timing
is perfect for such an application, because there's a delay between

antennas (active and/or preamp). It would be really cool if the 12v output

set in the menus to 0v (OFF) on PTT we could power our preamps via that jac

I'd like to clarify this a bit.
While the K3 does have some protection against over voltage on its supply, we
do not garantee it will survive an overvoltage event in all cases.

Why bother? The K3 already provides all of the capability of the
W2IHY 8 band EQ/noise gate, adds downward expansion in the noise
gate and there is no issue with external hum loops, RF pick-up, etc.

It is my experience that it takes more "set up" to get your transmitted

John,
Try putting a low pass filter in the 28 MHz output path from the K60XV.
Most any with a cutoff frequency above 30 MHz will do.
Sometimes the transverter couples a bit of its output frequency energy
back into the K60XV and overwhelms the power detection circuit. If that
happens, the K2 '
