there's a couple of people on lemmy believing that immortality magic tech is real

i think it's possible that's a cost cutting measure on part of openai

it also requires zero effort on their part

wait, it sounds like you want to use something called four square antenna, but it's usually only made for HF. you'd have to rework it significantly for microwave region http://tm1o.free.fr/4SQ/80m/en_ver_final4-sq_03_04_15.pdf instead of transformers you'd have to use segments of transmission lines with right impedances and some directional couplers, gives direction immediately, no need to compare phase between different SDRs

Or if you want to get more involved, make a couple of 3el yagis, make a small phased array out of these by plugging them in a directional coupler or 4x4 butler matrix and this will get you two or four receiving directions in a 90 degree segment. If you only want to use that small segment you don't need a LPDA, regular yagi would be fine

it's a mining area (underground copper mine is in the same town)

Transformers in antennas are just transformers, but you have to use ceramic cores (ferrites) that would be right for your band. I think that what you might be trying to do would be wideband antenna of some sort, but for UHF which is likely in this case, I'd recommend you some kind of log-periodic antenna instead (it just works, directional) or some kind of spiral antenna (it just works, nondirectional). You can make both of these at home

 

some communities are stuck in past, some 1d, some 1 month+. maybe it's because of old lemmy version (0.19.3 was released 22.01.2024). release notes for 0.19.4-0.19.10 don't suggest that these are breaking updates. 0.19.4 and 0.19.6 are big ones. 0.19.4 requires postgresql 16 and pictrs 0.5+ and it passed security audit. 0.19.6 recalculates something meaning that update takes longer. most of instances still on this version are down or badly broken, and these few that still are up seem to have the same problem

i guess it promotes touching grass, if that's your intention, fine,
