The FCC cited the Houston, Texas based importer Amcrest Industries which owns and operates Baofeng radio US for illegally marketing UV-5R, "capable of operating outside the scope of its equipment authorization," the FCC Citation said, which is outside of its Part 90 authorization granted. The FCC asserts Amcrest marketed "UV-5R-series FM hand ...

The original allocation of channels consisted of only channels 1 to 28 with 50 kHz spacing between channels, and the second frequency for full-duplex operation 4.6 MHz higher. Improvements in radio technology later meant that the channel spacing could be reduced to 25 kHz with channels 60 to 88 interspersed between the original channels.
Channel 16 VHF (156.800 MHz) is a marine VHF radio frequency designated as an international distress frequency. [1] Primarily intended for distress , urgency and safety priority calls, the frequency may also carry routine calls used to establish communication before switching to another working channel.

Channels 4 and 5 may use either "wideband" FM (5 kHz deviation; 20 kHz bandwidth) or "narrowband" FM. [5] All five channels may use amplitude modulation with a bandwidth up to 8 kHz. [ 6 ] MURS falls under part 95 and was not mandated for narrow-banding, such as those of Part 90 in the public service bands by January 2013.
Many hybrid radios have an ERP that is lower than 0.5 watts on channels 1–7, or can be set by the user to operate at low power on these channels. This allows hybrid radios to be used under the license-free FRS rules if the ERP is less than 0.5 watts and the unit is certified for FRS operation on these frequencies. [ 2 ]
