> For the 70cm equipment, I participated in VHF/UHF contests with multioperator groups. Why? This is a genuine question! I know I am genuinely uninteresting because I don’t know why I would do this if there wasn’t already a built-in audience. This seems adjacent to shouting into the void if one doesn’t already know that there are listeners/receivers. Why does anyone do this at all?

It's an organized event, just like Field Day. The most popular one is in June, since sporadic-E propagation on 50 MHz is available. https://www.arrl.org/june-vhf https://www.arrl.org/june-vhf To be honest, I've pretty much phased out on conventional ham radio. The last time I was out in the field was 2010. These days all my ham radio activity is for SDR (Software Defined Radio) development testing. Here's my Github. https://github.com/drmpeg https://github.com/drmpeg And here's a demo video of my open source ATSC 3.0 transmitter. https://www.youtube.com/watch?v=bLn5L-k4EPA https://www.youtube.com/watch?v=bLn5L-k4EPA
