Radio type compatibility checker

Pick two of 19 radio types and a country. The checker says whether the two can talk directly, under which conditions, how they can be linked, and lists band, channels, power and license side by side.

Compare two radio types

Pick two kinds of radio: see how they differ and whether they can talk to each other.

How the checker works

Two radios talk only when they share a band and a protocol. The checker first looks for a pair that standards or makers document. FRS and GMRS are one such pair: they share 22 channels.1 For any other pair it gives the reason they cannot talk. The bands may differ, one radio may be analog and the other digital, or two digital standards may not decode each other. DMR446 and dPMR446 are an example: same 446 MHz band, no common language.23

When a direct link is impossible, the checker lists the equipment that joins the two. That can be a dual-mode radio, a mixed-mode repeater, a radio-over-IP gateway or a cross-band repeater. It also shows the rules that limit them. PMR446 radios, for example, may not work as a repeater or as part of a network.4

The license row reads the rules of the chosen country from our license table.
