RigRef

RigRef is the offline quick-reference and toolkit your two-way radio forgot to include. When you can't remember which menu unlocks the keypad, sets a repeater offset, or turns on the weather alert — and there's no signal to look it up — RigRef has the answer, saved on your phone.

36 RADIOS, 980+ HOW-TO CARDS
Step-by-step instructions for the radios people actually own: Baofeng UV-5R, UV-82, UV-9R Plus, BF-F8HP, AR-5RM; Quansheng UV-K5/K6 (including egzumer custom firmware); Yaesu FT-60R, FT-65R, FT-4XR, VX-6R, FT-70D, FT5D, FT3D; Icom IC-V86, IC-T10, ID-52; Kenwood TH-K20A, TH-D74A; GMRS from BTECH, Wouxun, Radioddity and Midland; DMR from AnyTone, TYT and more. Every card lists the exact buttons and menu items.

Search across every radio at once ("how do I scan?") or browse one radio by category — power, memory channels, tones, repeaters, scanning, digital, and more.

OFFLINE TOOLKIT
On-device tools that work with no signal:
- RF calculators: antenna length, coax loss, repeater offset, SWR/return loss, power & ERP, DC voltage drop, range/line-of-sight, grid square, and battery life.
- A contact (QSO) logbook with one-tap ADIF export.
- A channel/memory editor that validates entries and imports/exports CHIRP CSV to program your radio.
- An ICS-205 net log to build a comms plan and track check-ins.
- Repeaters Near Me: sort imported repeaters by distance and bearing using GPS and the compass.
- A tone generator: DTMF, 1750 Hz tone burst, CTCSS and reference tones.
- A camera scanner that reads a printed frequency list into editable channels.

WORKS WHEN NOTHING ELSE DOES
Everything is stored on your device. No account, no sign-in, no internet required.

EMERGENCY & PREPAREDNESS FREQUENCIES
A bundled, offline list of common US frequencies — FRS, GMRS, MURS, CB, marine, NOAA weather, and ham calling channels — with notes on what needs a license.

REPEATERS, OFFLINE
Import a CHIRP/CSV repeater list (export from RepeaterBook in CHIRP format) and browse it offline with band and mode filters. Data courtesy of RepeaterBook.com.

FIELD COMMS PLANNER
Build the channels your team will actually use on a trip or operation, then share them phone-to-phone with no internet (Supporter feature). Receiving a plan is always free.

READABLE IN THE FIELD
Field Mode bumps the text size for gloves, bright sun, or shaky hands — free for everyone.

FREE, WITH AN OPTIONAL SUPPORTER UNLOCK
All reference content and tools are free, forever. An optional Supporter unlock adds color themes, alternate app icons, a red Night Vision mode, and over-the-air plan sending. Tips are welcome but never required.

IMPORTANT
RigRef is a quick reference, not a substitute for your radio's manual. Procedures vary by firmware and region — always confirm against your actual radio. Transmitting on some services requires a license; you are responsible for operating legally.
