An auxiliary station, most often used for repeater control or link purposes or to remotely control another station, is limited in the United States to operation on frequencies above 144.5 MHz [16] excluding 144.0–144.5 MHz, 145.8–146.0 MHz, 219–220 MHz, 222.00–222.15 MHz, 431–433 MHz, and 435–438 MHz.
Repeaters are found mainly in the VHF 6-meter (50–54 MHz), 2-meter (144–148 MHz), 1.25-meter band (1 1 ⁄ 4 meters) (220–225 MHz) and the UHF 70 centimeter (420–450 MHz) bands, but can be used on almost any frequency pair above 28 MHz. In some areas, 33 centimeters (902–928 MHz) and 23 centimeters (1.24–1.3 GHz) are also used for ...
The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz, and 420 through 450 MHz (plus 1240 through 1300 MHz with the "X" model). The sub-receiver tunes between 118 and 174 MHz, and from 220 to 512 MHz (VFO ranges).
This list contains the mobile country codes and mobile network codes for networks with country codes between 300 and 399, inclusively – a region that covers North America and the Caribbean. Guam and the Northern Mariana Islands are included in this region as parts of the United States.
Apart from their main spectrum holdings across large regions in the country (listed below) the major US carriers (AT&T, Sprint, T-Mobile & Verizon) also hold various Cellular Market Area (CMA) and/or Economic Area (EA) licenses for the AWS 1700 band, as well as Major Trading Area (MTA) and/or Basic Trading Area (BTA) licenses for the PCS 1900 band.

Beacons traditionally operate in the lower part of the band, in the range 50.000 MHz to 50.080 MHz. IARU Region 1 is encouraging individual beacons to move to 50.4 MHz to 50.5 MHz. [ 4 ] [ 5 ] In the United States , the Federal Communications Commission (FCC) only permits unattended 6-meter beacon stations to operate between 50.060 and 50.080 MHz.
