Grant comment: "Output power listed is ERP. This device is authorized to operate in GMRS (Part 95E) radio service." The filed Part 95E test report (AGC10590240102FR02, test model TD-H3) gives a rated output of "1.5W/0.5W," an "Inseparable Antenna" of 2.15 dBi and a 7.4 V 2600 mAh battery. TIDRADIO's separate ham/unlocked TD-H3 grant, 2A4FBTD831, has no Part 95E transmit rows. Check that the label on your radio reads 2A4FBTD831G before using it on GMRS.

Maker's claims vs FCC filing

Maker says

"5W Radio Handheld" (TIDRADIO TD-H3 listing) source

FCC filing shows

GMRS grant 2A4FBTD831G: 1.4 W ERP max (462 main). Filed test report: rated output 1.5 W / 0.5 W grant

Our read

This is the biggest gap in our database. TIDRADIO's 5 W listing is for the Ham/Unlocked TD-H3, and the GMRS-certified version was filed at about 1.5 W. On GMRS, expect the GMRS version's filed power, not 5 W.

Maker says

Ham, GMRS and unlocked versions sold under one TD-H3 name source

FCC filing shows

2A4FBTD831G is the GMRS (Part 95E) grant; 2A4FBTD831 lists only receive rows and Bluetooth grant

Our read

Only a radio carrying the 2A4FBTD831G label is certified for GMRS.

"Not listed" means this model isn't on the NWS list of radios approved for the NOAA Weather Radio All Hazards logo. It doesn't mean the radio can't receive weather broadcasts. The maker pages we checked don't say whether alerts use SAME county codes. See the weather radio guide.
