Very lightweight SOTA microphone

I have been looking for an alternative to the rather bulky and heavy Elecraft MH3 handheld microphone for quite some time. Since I mainly operate CW, the solution could be somewhat improvised.
Inspired by an article about a very light microphone in the SOTAreflector, I started the following mini-project:

A headset from my Baofeng UV-5R was available, lying around unused. The aim was to replace its weird dual plug with a simple 3.5 mm stereo plug and change the wiring so that it could be used with the KX3. The tiny speaker I would simply trim as I’m already using earbuds for my activations.

Happy anniversary!

100

The activation of DM/BW-852 (Herrenwald) was my 100th activation of a SOTA- reference. As I started activating on a regular basis back in 2015, it has been approximately 16 summits per year in average since then. The most active year was 2020, though, with 40 activations.
I’m quite happy with this achievement as I have family, job and several commitments, all with higher priority than playing radio and climbing mountains.
