As a result, it was not authorized for use in the GMRS and FRS, only for amateur radio. [5] [6] Baofeng launched a number of other models based on the UV-5R technology, since 2012. Other radios from other Chinese manufacturers have mainly the same range of functions, specs and menu like the UV-5R, for example the Retevis RT5. [7]
While radios designed for the Taiwan market have FRS/GMRS frequencies as part of their channel plan, it is still technically illegal to use equipment designed for the Taiwan market in the United States. FRS, 14 channels, 12.5 kHz spacing: 467.5125 MHz; 467.5250 MHz; 467.5375 MHz; 467.5500 MHz – US GMRS Repeater Ch 15/23 Input
In some repeater systems, the time lag can be significant. The lower tone may cause one or two syllables to be clipped before the receiver audio is unmuted (is heard). This is because receivers are decoding in a chain. The repeater receiver must first sense the carrier signal on the input, then decode the CTCSS tone.
The manual frequency provides a common frequency for all members of the network to verify that the equipment is operational. During initial net activation, all operators in the net tune to the manual frequency.
