  • You can buy a cheap Chinese HT like a Quansheng UV-K6 for like $40. These have open firmware and there’s a bunch of custom options radio nerds have whipped up. Get the USB programming cable even if you’re not doing custom FW, makes programming frequencies and tweaking options much easier. You’ll also need a license and in the US, HamStudy.org has the exact questions from the test. There’s a ton of YouTube channels you can watch and books you can read for general purpose radio knowledge. Then it’s just a matter of getting a proper antenna and pointing it in the right place at the right time; there’s free resources online, paid apps, all that is out there and it’s just a matter of wanting to learn it. The actual hardware you need to get started is really cheap these days.














  • This costs “less than $70”.

    You can get a cheap Geiger counter for $50 today and it’s about the same size. I see some for $30-40. These are based on old, proven technology, not some new thing with new unknown problems and an app.

    Not that it isn’t neat, but it’s kind of a solved problem.

    To put this into perspective, a 10 Gray dose to the skin is high enough to cause permanent hair loss.

    A 10Gy exposure is well, well beyond hair loss range and into the fatal within days zone. The LD50 is 5Gy, LD99 is 9Gy IIRC. Methinks the author did not do their research on the topic.
