Baofeng MP31 Review: A GMRS Pair With an FRS Radio's Power

Baofeng sells several radios that look alike and behave very differently, and the MP31 is the one people find by searching the model number after seeing the price. It is a certified GMRS handheld — FCC ID 2AJGM-MP31 — sold as a two-radio box with two earpieces and a single charging cable, at the very bottom of the budget tier.

This review is built entirely from what Baofeng and its US dealer publish, read on 2026-10-26, plus the FCC rules the radio has to live inside. We do not test radios, and we say so plainly on how we rank. That turns out to be enough here, because the most important thing about the MP31 is printed in its own spec table.

What the MP31 is

A sealed-battery, keypad-and-display GMRS handheld, 9 in tall without its 5.1 in antenna and 0.2 lb each, rated IP54 for dust and splashing. The box contains two radios, two batteries, two antennas, two belt clips, two wrist straps, two headphones, a charging cable, an adapter and a manual (Baofeng's MP31 page). Both Baofeng's own store and Radioddity's listing showed it in stock on the day we read them.

Two details separate it from the toy end of the shelf. The antenna is a removable SMA-female fitting, so a longer whip is a legitimate upgrade later — something no FRS radio is allowed to offer, because FRS antennas must be permanently attached. And it charges over a "2-in-1 Type-C Charging Cable", meaning both radios fill from the cable already in your truck.

The published specs

The headline numbers, all from Baofeng's own page unless noted: 2 W on GMRS channels 1 to 7 and 15 to 22 and 0.5 W on 8 to 14; 22 GMRS channels plus 8+8 repeater channels; 10 NOAA weather channels to scan and receive; 260 tone and code combinations (50 CTCSS, 210 DCS); IP54; a 1500 mAh 3.7 V Li-ion pack charged by a 2-in-1 Type-C cable, with Radioddity listing up to 18 hours; a removable SMA-female antenna; and 0.2 lb per radio. The full table, with every figure linked to the page it came from, is in the card further down this page.

The catch: a licensed radio with an unlicensed radio's power

Here is the line that decides whether this radio is right for you. Baofeng states the MP31's output as "2W (1-7&15-22 Channels) /0.5W(8-14 Channels)". Those are, almost exactly, the legal power limits for the license-free Family Radio Service: 2 W on channels 1 to 7 and 15 to 22, and 0.5 W on channels 8 to 14 (47 CFR 95.567). Meanwhile GMRS allows considerably more on those same main channels (47 CFR 95.1767), which is why most GMRS handhelds advertise 5 W.

So the MP31 is a radio that requires an FCC license — it is certified under the GMRS rules, and GMRS requires an individual license before you transmit (FCC: GMRS, 47 CFR 95.1705) — while transmitting no harder than a radio you could have bought with no license at all. The FCC fee table lists $35 for a new GMRS license (FCC application fees), good for ten years and covering your immediate family.

What the license does buy on this radio

• Repeater channels. Baofeng lists "22 common GMRS Channels and 8+8 GMRS repeater channels". A repeater sits at what the rules describe as a favorable, high antenna location and re-sends your signal, which is the one jump that genuinely beats terrain — how GMRS repeaters work covers finding one and asking for access. FRS radios cannot use repeaters at all.
• A removable antenna. SMA-female, so a longer half-wave whip is an option on this radio and is illegal on any FRS radio. Our GMRS antenna picks list the handheld whips that fit that thread.
• Headroom to upgrade one end. A GMRS license also covers a 5 W handheld or a 15 to 50 W mobile in the truck later, talking to the same channels — see handheld vs mobile range.
• Your household, under one license. One license, ten years, and it covers immediate family (47 CFR 95.1731). For a family with a cabin or a property that is genuinely useful; for a team of friends it is not, and license-free FRS is the right answer.

Range: the two numbers do not agree

Baofeng's own MP31 page claims "up to 3 miles with obstacles". Radioddity, its US dealer, lists the same radio at up to 5 miles with obstacles. Both are advertising figures rather than measurements, and we label them as claims wherever they appear on this site — but when a maker and its own dealer differ by two miles on the same model, that is worth knowing before you plan around either number.

What a 2 W handheld with a stubby antenna actually does is more like a few hundred yards to a mile in timber or suburbs, and several miles only with height and a clear path. That is not a knock on this radio specifically; it is physics, and how range claims are generated explains where the box numbers come from. If you need more, the honest fixes are height, a longer antenna or a repeater, in that order — how to increase walkie-talkie range.

Who should buy it

Buy it if you want a licensed pair for a family at a camp, a property or a convoy at short range and you value the hardware: USB-C charging, IP54, earpieces included, a removable antenna and repeater channels for later. At this price it is also the cheapest way for one household to find out whether GMRS and a local repeater are worth going further with, before spending real money on a 5 W handheld or a mobile radio.

Skip it if any of the following is true:

• You wanted the power step up. At 2 W it transmits no harder than a license-free pair. A 5 W GMRS handheld is the radio you are actually thinking of.
• The radios are for friends, a crew or a team. A GMRS license does not extend to people outside your immediate family (47 CFR 95.1705). FRS radios are the lawful answer there — the license-free picks.
• You will not file for the license. Transmitting on GMRS without one is not legal, and this radio is certified only under the GMRS rules (47 CFR 95.1761). Buy an FRS radio instead; it is the same 2 W.
• You need long battery days. 1500 mAh is small, there is no AA fallback, and the only runtime figure published anywhere is Radioddity's "up to 18 hours".
• You want to program channels from a computer. Baofeng states plainly that the "Programming cable not included", so out of the box it is keypad editing only.

The alternatives, if the MP31 is not the one

Three radios cover the three reasons someone walks away from this one — wanting real 5 W, wanting no license at all, or wanting a radio with a support story and an antenna jack:

If you are weighing the brand rather than the model, our Midland vs Baofeng comparison sets the cheap-and- programmable approach against the factory-set-and-supported one, and the best Baofeng for a beginner sorts the lineup by what a first-time owner can actually operate.

The verdict

The MP31 is better hardware than its price suggests and worse value than its service label suggests. Judged as a cheap pair of radios it is strong: USB-C, IP54, two earpieces, a removable antenna, 260 tone and code combinations, NOAA weather receive and repeater channels. Judged as a GMRS radio it is the weakest kind, because the headline advantage of the licensed service — more power — is not there.

That makes the buying decision unusually clear. If the $35 license is going to happen anyway and you want repeater access in a family's hands for the least money, it is a sensible buy. If the license was going to be the price of extra range, spend a little more on a 5 W radio, or save the fee and buy a license-free FRS pair that transmits exactly as hard — GMRS vs FRS is the five-minute version of that decision.
