That's awesome, seems like a great contribution to the community. CB radio, too, that's not so common these days. I scan for it sometimes but never find any local traffic.
- zhengyi13 3y agoI get the sense that there are some folk still actively using CB, but I also have the sense that for most people, their needs are better met nowadays by GMRS radios (which are in the UHF/~70cm bands, rather than 11m CB), which provide for legally higher power transmissions, at the cost of a nearly completely unenforced license. Part two of course is location: I'd expect CB to be more prominent on big cross-country highways; GMRS in wide-open country where folks might be overlanding. If you're hanging out in a city and expecting to hear either, I think you're liable to be disappointed.
- jstarfish 3y agoCB is line-of-sight, isn't it? It's mostly used by freeway truckers for very short-range comms that you don't need to broadcast across the entire state (accident/speed trap ahead/nearby Hooters fails health code inspections).
- ddingus 3y agoNot quite. It has a long wavelength. 11 meters, and that means it will propagate like "Short Wave" and HF (high frequency) commercial broadcasts tend to do. The line of sight signals happen at much higher frequencies. VHF and higher. (GHZ)
- themodelplumber 3y agoQuite a few interesting trans-Atlantic CB contacts on YouTube these days. They are all using SSB though I think. Not super common in handhelds.
