Retevis Radios Frequency List

Looking for the frequencies used by your Retevis radio? Whether you own an RT22, RT21, RT29, RB27, or another popular model, finding accurate channel and frequency information can save time when programming radios, troubleshooting communication issues, or verifying compatibility with other systems.

Retevis manufactures radios for several different radio services, including FRS, GMRS, MURS, and commercial business bands. As a result, two radios that look similar may operate on completely different frequencies and have different licensing requirements.

This guide provides a comprehensive frequency list for popular Retevis radios, making it easy to identify your channels, understand how your radio operates, and choose compatible equipment for your next upgrade.

Here is a list of frequencies commonly used for Retevis radios, including the RT21, H-777S, and RT22 models:

Retevis RT22 Frequencies

The Retevis RT22 has 16 preset channel positions. An important point is that the RT22 channel number is not necessarily the same as the official FCC FRS channel number.

For example, RT22 preset Channel 1 uses 462.6250 MHz, which corresponds to FRS Channel 18 under the FCC frequency plan.

Here is the corrected mapping for the RT22 configuration shown below:

RT22 Preset	Frequency	FCC FRS Channel	CTCSS
1	462.6250 MHz	FRS 18	127.3 Hz
2	462.7250 MHz	FRS 22	136.5 Hz
3	462.5625 MHz	FRS 1	67.0 Hz
4	462.5875 MHz	FRS 2	71.9 Hz
5	462.6125 MHz	FRS 3	74.4 Hz
6	462.6375 MHz	FRS 4	77.0 Hz
7	462.6625 MHz	FRS 5	79.7 Hz
8	462.6875 MHz	FRS 6	82.5 Hz
9	462.7125 MHz	FRS 7	85.4 Hz
10	462.5500 MHz	FRS 15	88.5 Hz
11	462.5750 MHz	FRS 16	91.5 Hz
12	462.6000 MHz	FRS 17	94.8 Hz
13	462.6500 MHz	FRS 19	100.0 Hz
14	462.6750 MHz	FRS 20	103.5 Hz
15	462.7000 MHz	FRS 21	107.2 Hz
16	462.7250 MHz	FRS 22	110.9 Hz

Why the RT22 Channel Numbers Look Different

The numbers announced or selected by the RT22 are memory or preset positions, not the standardized FRS channel numbers defined by the FCC.

This particular RT22 configuration uses FRS Channels 1–7 and 15–22. It does not use FRS Channels 8–14, which operate on frequencies between 467.5625 and 467.7125 MHz.

Notice also that FRS Channel 22, 462.7250 MHz, appears twice in the RT22 preset list. RT22 presets 2 and 16 use the same RF frequency but different CTCSS tones.

CTCSS does not create a separate radio frequency or private channel. It simply allows a radio to mute transmissions that do not carry the selected tone.

RT22 Power Limits

Under current FCC rules, FRS Channels 1–7 and 15–22 may operate at up to 2 watts ERP, while Channels 8–14 are limited to 0.5 watts ERP.

Current Retevis specifications list the RT22 as a 16-channel FRS radio with transmitter output power of 2 W/1 W, depending on the setting.

A Note About Different RT22 Versions

Retevis has sold different versions and production revisions of the RT22 over the years. Factory frequency and CTCSS/DCS programming may therefore differ from the table above.

If you need to match an RT22 with another radio, check the actual frequency and CTCSS/DCS settings using the appropriate Retevis programming software or documentation for your specific radio.

Correction: Thanks to a OneSDR reader who contacted us and pointed out that an earlier version of this article incorrectly treated the RT22 preset numbers as official FCC FRS channel numbers. We appreciate the correction.
