You can get a pack of 4 of these for £17. They are advertised as 400-470mhz 3km range, but are actually on pmr446. They are badged Retevis, Floureon and a few other names. How cheap radio has become! Since they are probably wideband SDR technology like most Chinese rigs, I was wondering if it would be possible to jailbreak them for wideband coverage. No ctcss though.
