[Elecraft] KX2 remote control via the MH3 mic: ready for mobile/portable testing

[Wayne Burdick]

Hi all,

We’re looking for volunteers to test new firmware that allows extended control of the KX2 via an MH3 mic. This feature enables “HF Pack Lite” operation, where the radio is inside a backpack with a whip attached. It’s also useful for mobile operation since it allows eyes-free radio control.

I’ve been using it on hikes, with excellent results. I use a small REI sling pack and a thin, flexible 44” whip to get as close to “stealth” HF operation as possible.

Mic-based functions include:

- VFO up/down (default)
- CW message play
- CW handkey
- filter bandwidth
- AF gain
- VFO A/B swap
- mode
- band
- ATU tune
- power output
- battery voltage
- power OFF

The UP/DN buttons are used to access the various functions. Tapping PTT returns to VFO up/down, while a double-tap of PTT reports the operating frequency in kHz (using audio Morse tones).

If you’d like to give the new firmware a try, please email me directly.
