Amateur Radio UHF Simplex Frequencies
Amateur Radio frequencies in US/Canada within the 70 Centimeter (aka 440) band include a segment of frequencies allocated for FM simplex operation. The frequencies range from 445.000 MHz to 447.000 MHz, inclusive, with a commonly observed spacing (or stepping) of 25 kHz. This makes available 81 possible frequencies for two-way FM operation in this allocation. (In areas where a 12.5 kHz spacing is being observed, there are 161 possible frequencies.)
This band (400 MHz UHF) and mode of operation (FM, Simplex) is fairly identical to the popular Family Radio Service (FRS) and General Mobile Radio Service (GMRS) blister pack radios popular in the United States and Canada, and with Australia UHF Citizen's Band (UHF CB) radios, and with Professional Mobile Radio (PMR446) radios in the United Kingdom. In fact, PMR446 overlaps with the 446 MHz Amature Radio band being described here, but use a different set of channelized frequencies. Indeed, equipment intended for any one of these radio services can often be used on the others.
Standard Repeater Offsets
Band | Offset MHz |
---|---|
10 m (29 MHz) | - 0.1 |
6 m (50 MHz) | - 0.5, - 1.0 |
2 m (144 MHz) | +0.6, - 0.6 |
1.25 m (222 MHz) | - 1.6 |
70 cm (440 MHz) | +5.0, - 5.0 |
33 cm (902 MHz) | - 25.0, - 12.0 |
23 cm (1.2 GHz) | - 20.0 |
- Some repeaters have non-standard offsets. These are often referred to as odd split repeaters.
- Some areas may use band plans with different offsets.
