The FCC asserts Amcrest marketed "UV-5R-series FM hand-held radios capable of transmitting on 'restricted frequencies'". [10] Later revisions of the UV-5R sold in the US had transmission frequencies locked to the ham bands, however, there exists a key combination to unlock the ability to transmit on the full band. [11]
BaoFeng UV-5R. The Baofeng UV-5R is a hand-held radio that has been marketed in the United States [6] and was produced since 2012. [7] It has been used in a number of projects involving radios. [8] [9] It is described as a popular inexpensive model. [6]
In 2013, the BaoFeng UV-82X, an inexpensive 2-meter / 1.25-meter handheld, became available. [citation needed] During 2021, Baofeng then introduced its latest, and cheapest, UV-5r III handheld transceiver, which now includes the 1.25 meter band as standard. Several 1.25-meter base/mobile transceivers are available.
Naval air traffic controller communicates with aircraft over a two-way radio headset A variety of portable handheld two-way radios for private use. A two-way radio is a radio transceiver (a radio that can both transmit and receive radio waves), which is used for bidirectional person-to-person voice communication with other users with similar radios, [1] in contrast to a broadcast receiver ...
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.
Five 2.8 kHz-wide channels are available in the U.S., centered on 5.332, 5.348, 5.368, 5.373, and 5.405 MHz. Since most radios in SSB mode display the (suppressed) carrier frequency, in USB mode the dial frequencies would all need to be set 1.5 kHz lower. Voice operation is generally in upper sideband mode, which is mandatory in the U.S. . The ...

A walkie-talkie, more formally known as a handheld transceiver, HT, or handheld radio, is a hand-held, portable, two-way radio transceiver.Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski and engineering teams at Motorola.
