Common Ham Radio Repeater Channel Spacings and Offsets
| Band | Output Frequencies of Each Group (In MHz) |
|---|---|
| 222 MHz or 1-1/4 meters | 223.85 – 224.98 |
| 440 MHz or 70 cm (local options determine whether inputs are above or below outputs) | 442 – 445 (California repeaters start at 440 MHz) |
| 447 – 450 | |
| 1296 MHz or 23 cm | 1282 – 1288 |
What frequencies are in the 70cm band?
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
Is 2m UHF or VHF?
Common dualband transceivers, both mobile and handheld, operate on the 2m and 70cm bands. These radios are so common that we often refer to them as VHF/UHF dualband radios. Accordingly, you will often hear hams refer to the 2m band as simply VHF and the 70 cm band as UHF, as if VHF means 2 meters and UHF means 70 cm.
What frequency is best for ham radio?
20 meters – 14.0–14.35 MHz – Considered the most popular DX band; usually most popular during daytime. QRP operators recognize 14.060 MHz as their primary calling frequency in that band. Users of the PSK31 data mode tend to congregate around 14.070 MHz. Analog SSTV activity centers on 14.230 MHz.
Can ham radios talk to CB radios?
Can ham radio be used as a CB radio? Generally, the answer is no. If a licensed amateur radio operator wanted to speak on a CB frequency range, the operator would need to use a CB radio. That said, amateur radio can be used in many applications where people currently use CB radios.
Why is it called 70cm band?
The reason it is called the 70 cm band is because the approximate wavelength of an RF signal in that band is 70 cm. If you recall, wavelength in m = frequency in MHz / 300. 432/ 300 is about 0.7m or 70 cm.
