Good points, John,One thing we perhaps can do is stir up enthusiasm among ourselves - I have listened on LF but never attempted transmit activities, and I suspect I am not alone in that.
I am a complete ingrate when it comes to HTML, but did once make a website, so perhaps I can help. Let's discuss that ;-)
Antennas are pretty recalcitrant in sticking to physics, but I do feel it is interesting to explore more on this, as there might be value (and general understanding to be learned) for some specific cases.
Oh. And I am still trying to dream up ways to make LF signals without using typical electronic devices.
It is great to see active discussion on the board!
