I used the equipment for the same reason, to communicate through the Oscar 10 and 13 satellites at home. Oscar 10 was launched in 1983. At that time, I was living in an apartment. I strung up some smaller yagis on the balcony that fortunately faced towards the southwest. I was able to use some, but not all passes of the satellite.
I also used the equipment for terrestrial communications. When I started renting a house, I put up a large yagi for 2-meters. With SSB, you can make contacts out to about 300-400 miles. Enough for contacts between Silicon Valley and the Los Angeles area.
I also made much longer distance contacts with that station with special propagation modes. Meteor bounce, sporadic-E and trans-Pacific (Hawaii) ducting (about 2400 miles).
For the 70cm equipment, I participated in VHF/UHF contests with multioperator groups. This is where we'd go to mountain tops to operate. I was lucky enough to operate from Mt. Pinos a couple of times before ham radio was banned from there. Mt. Pinos is a 8847 ft. mountain at the southern end of the central valley and by far the best location for VHF/UHF operating.

Of course, this was in the 80's and 90's. Nowadays, weak signal VHF/UHF may not be very active where you live.
- aspenmayer 1y ago> 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?
- drmpeg 1y agoIt'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
- aspenmayer 1y agoThank you for your response. I am not active much on GH, but mine is: https://github.com/aspenmayer https://github.com/aspenmayer > And here's a demo video of my open source ATSC 3.0 transmitter. Wasn’t yet following you on Twitter, but was already subbed on YT. I see you, but I don’t recognize you. I will review my history to appreciate further your contribution(s) to my present state. I am going to DEF CON. I hope to see you there, but if not this year, perhaps sometime soon irl or online. To circle back, how did this happen: > > They found out that I had an Oscar 10/13 satellite station Specifically, how did they know > that I had an Oscar 10/13 satellite station ? Are there people fox hunting recreationally, all the time? https://en.wikipedia.org/wiki/Amateur_radio_direction_finding https://en.wikipedia.org/wiki/Amateur_radio_direction_findin...
