The most common VHF/UHF radios are basic FM mobile or handheld transceivers. These radios usually tune the entire 70 cm band from 420 MHz to 450 MHz in 5 kHz steps. The band plan indicates the proper range of frequencies for FM operation but there is more to the story.
Single-band equipment for 70cm is rare, but many dual-band transceivers are available that operate on both 2 meters and 70cm. Available gear includes base stations, mobile units and HTs. One single-band mobile FM transceiver for this band is Alinco’s 435.

It’s important to end up on the established channels to maximize the usage of the band - same way that using WiFi channels 1, 6, and 11 prevents overlap and allows APs to avoid contention. So you’ll want to check your regional coordinator’s band plan. 70cm is usually 12.5kHz.
13 maj 2018 · Why do most HTs have 2m and 70cm as the two bands? Is it just out of history or tradition, licensing restrictions, or is there something in the transceiver or antenna design that would make these the two obvious frequency bands of choice?
