The TIDRADIO TD-H8 is a versatile dual-band radio with GMRS (2w low/5w high) and HAM/Unlocked modes (2w low/5w middle/10w high). In HAM mode, it transmits on 144-148MHz & 420-450MHz, and receives on 136-174MHz & 400-520MHz. The unlocked mode extends transmission to the entire receive range. With a 10-watt output, this radio surpasses typical 5 or 8-watt models, offering extended communication range. Features include the first phone programming support from TIDRADIO, firmware updates, mode switching, wireless programming, and more like dual-watch, NOAA weather channels, and a vibrant 1.77-inch LCD color screen. Programming is simplified with the ODmaster App, which allows frequency editing, repeater searches, and sharing without data, alongside options like CHIRP and CPS software. Firmware updates introduce new features, keeping the radio up-to-date. Additionally, one-click repeater import and adjustable MIC gain from 0 to 32 enhance usability, responding directly to user feedback.
