If you compare the license holders and the population, the kind of "growth" that amateur licenses got is my point: proportion to the population of the US 2018-2023 had an increase of roughly 500 members, so around 100 per year. https://www.arrl.org/fcc-license-counts

Thank you for clarifying the point of its usage. Compared to something like SDRs, and meshtastic it's way more mature and has a lot less interesting specs to me besides it's frequency. I skimmed your blog and didn't see anything related to either radio. Is there a lot of overlap between sdr and ham? I only knew one who was a trucker that mostly just listened to local people.
