Inspired by a paper from HB9BCB I built my own version of a small and lightweight coupler for an EFHW dipole. It helps reducing the weight of my radio equipment for long hikes to alpine summits (see here).
Sometimes a summit offers little space to deploy an antenna. Either because there isn’t much room or because there are many people at the top – or both.
Then an antenna with a small footprint is required.
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.
Some time ago I had an S2S-QSO with N1ZF. In the following e-mail contact we exchanged information and photos about the antennas used for this QSO. This is when I became aware of the „Random Wire Antenna“ Paul had successfully used.
