Pick an FRS, GMRS or MURS channel and get the exact frequency and settings to program into your radio.
TrailBand is built for offroad and overland groups, where some vehicles carry bubble-pack FRS walkie-talkies from the hardware store, others carry programmable handhelds, and nobody can work out how to make the two talk to each other. It covers all 35 channels: FRS/GMRS 1 to 22, the eight GMRS repeater pairs, and MURS 1 to 5.
Every channel shows what a radio actually needs to be told: receive and transmit frequency, the repeater offset and shift, bandwidth, tuning step, and which power setting keeps you inside the legal limit for that channel. The tone screen maps the “privacy codes” printed on consumer radios onto the real CTCSS tones, so when somebody says they are on channel 16, code 22, you know that means 462.5750 MHz with a 141.3 Hz tone.
When the whole group needs the same setup, export the set as a CHIRP-compatible CSV and program the radios over USB, or send a plain text programming card so everyone can key it in by hand. Agree the channel once in the staging area, and every radio in the convoy ends up identical.
Features
- All 35 channels: FRS/GMRS 1 to 22, GMRS repeater pairs 15R to 22R, and MURS 1 to 5
- Receive and transmit frequency, offset, bandwidth, tuning step and power setting for every channel
- 38 standard CTCSS tones shown with their bubble-pack privacy code numbers, plus 12 extra tones and 104 DCS codes
- Search by channel number, or by a frequency you heard and want to identify
- Favorites for the channels your group actually runs
- Export a CHIRP-compatible CSV to program a radio over USB, with the tuning step set correctly per channel
- Share a plain text programming card so nobody has to be talked through it over the air
- Reference articles on FRS against GMRS, MURS, matching consumer radios, using a repeater, and choosing a trail channel
- Works fully offline. No accounts, no ads, no tracking, no network access at all
Frequencies, bandwidths and power limits follow the United States FCC allocations in 47 CFR Part 95, Subparts B (FRS), E (GMRS) and J (MURS).
