Key differences

Filed power: the GM-30 is a little higher, mostly on channels 1–7. Both grants list ERP (measured with the radio’s own antenna), so they compare directly (2AN62-GM30, 2AGND-GMRS-V2):

• 462 MHz main channels: GM-30 4.91 W vs GMRS-V2 4.6 W (about 0.3 dB).
• 467 MHz repeater inputs: 4.9 W vs 4.59 W (about 0.3 dB).
• 462 MHz interstitials (FRS 1–7): 4.89 W vs 3.64 W (about 1.3 dB). This is the one gap worth knowing about.
• 467 MHz interstitials (FRS 8–14): 0.49 W vs 0.46 W. Both are just under the 0.5 W ERP handheld limit (§95.1767(c)).

The GM-30 sits at 98% of the limit on channels 1–14 (4.89 of 5 W, 0.49 of 0.5 W). A longer, higher-gain whip adds to what radiates, so on those channels a stock antenna is the safe choice. Use an upgraded whip on 15–22 and repeaters, where the limit isn’t set as ERP (handheld antenna upgrades). r/gmrs has a thread on measured power output of the GM-30; those are owner measurements, not the FCC figures above.

Antennas: opposite SMA types. BTECH lists an “SMA-Female antenna” for the GMRS-V2. Radioddity says the “GM-30 uses SMA-M antenna.” So the two radios have opposite jacks, and a whip for one won’t thread onto the other without an adapter. Both have removable antennas and a Kenwood-style 2-pin (K1) accessory jack, so speaker mics and programming cables are shared (connectors explained).

Water and dust. BTECH rates the GMRS-V2 IP54 (“weather-resistant / splash resistant”). Radioddity lists no IP rating for the GM-30.

Where the grants come from. The GMRS-V2 grant is BTECH’s own original filing (2021-10-26). The GM-30 grant (2021-04-19) is a change in identification of 2AJGM-P15UV, granted 2021-04-13 under grantee code 2AJGM, the code that also holds Baofeng’s UV-5G Plus and GM-15 Pro grants. The FCC figures above are the ones filed for the GM-30’s ID.

Emission codes. The GM-30 grant lists 16K0F3E on the main channels and channels 1–7, and 11K0F3E on 8–14. The GMRS-V2 lists 15K1F3E on the main channels, 11K4F3E on 1–7 and 8K48F3E on 8–14. Both use wideband FM on the main channels and repeaters.

RF exposure. Both grants say to hold the radio at least 25 mm from your face and set a 50% maximum duty factor. Highest reported SAR: GM-30 0.74 W/kg face-up and 1.29 W/kg body-worn; GMRS-V2 0.88 and 1.46 W/kg.

Range claims. Radioddity says the GM-30 “can go up to 5 Miles.” BTECH says “1–5+ miles” simplex for the GMRS-V2. The FCC doesn’t certify range, and the filed power difference is too small to change it much (GMRS range).

r/gmrs threads on these two: Radioddity GM-30 vs ???, Should I go ahead and get a GM-30 now or wait and Radioddity GM-30 Plus or Pro. The GM-30 Plus is a separate model that isn’t in our database yet.

Which one fits you

• Lowest cost, or a family set: the GM-30. At $24.99 it has the lowest list price of any handheld in our database, with the highest filed ERP on channels 1–7 of the two.
• Rain, dust or a stated weather rating: the GMRS-V2 (IP54). For full waterproofing, look at IP67 handhelds in best GMRS handheld radios.
• You plan to buy a Nagoya NA-771G or similar SMA-Female whip: the GMRS-V2, which BTECH sells it for.
• You run two channels at once (a repeater and a simplex channel): the GMRS-V2’s dual PTT.
• Comparing with Baofeng’s GMRS models: see UV-5R vs UV-5G vs GMRS-V2, or GMRS-V2 vs GMRS-PRO if you’re thinking of stepping up.

Licensing: both transmit on GMRS, so you need an FCC GMRS license (how to get one). Both grants list rule part 95E.

The GM-30's weight and IP rating, the GMRS-V2's battery capacity and warranty, and SAME support for both radios are not yet verified.
