Radio Frequency Guide

Most off-the-shelf radios use Family Radio Service (FRS). You can tune your programmable UHF radio to the matching frequencies below to use the two types of radios together:

CTCSS Privacy Codes

Often these will be called "privacy codes" or "subchannels" on FRS radios.
Set both CTCS-R (receiving code) and CTCS-T (transmitting code) to the matching frequencies below on your programmable radio to communicate with FRS radios using subchannels:

DCS Privacy Codes

Some FRS radios use DCS privacy codes instead of or in addition to CTCSS.
Set both DCS-R (receiving code) and DCS-T (transmitting code) to the matching frequencies below on your programmable radio to communicate with FRS radios using subchannels:
