I’m super new to radio with nobody I know knowing it, so noob alert - plus some extraneous details in case you can comment on any of those.
I got a pair of BaoFeng BF-F8HP radios with recommended antenna upgrades with the idea that my brother and I can eventually get licensed and talk over the 5 miles between our houses in dense suburbs. Seems plausible from the reviews, but haven’t tested yet.
Anyway, we’re just listening for now and there are a few emergency services I found through radioreference. Most in my area are encrypted and some are at like 700+Mhz that are beyond this radio’s uhf & vhf bands. (I think I can pick up P25 and FM, but not other modes). I was able reach more stations by decreasing the Freq Step size to the minimum 2.5khz, and also going to Narrowband mode for easier scanning (although scanning has been fruitless). Infrequently I hear morse go out on the otherwise vox channel. Perhaps they’re different bands and my narrow-band is still too wide? I haven’t found any broadcasts that sound like anything but regular old walkie talkies.
Main question: Why don’t these unencrypted FM emergency services seem to use any call signs or ham codes? Are they not required to because they aren’t operating as “amateur”s? And if not, why wouldn’t that type of activity get isolated bands instead of mixing two different vocal protocols in the same bands? And if I broadcast on any of the vast empty areas of the spectrum as a range test, who would know I wasn’t just some emergency/government service?
