Radioddity GA-510 vs TIDRADIO TD-H3

The TD-H3 edges out the GA-510 with better listed specs for the money, scoring 68 versus 64 overall. Both radios share identical core features: no DMR, APRS, or GPS support, and both offer CHIRP compatibility for programming. The GA-510 delivers 10W transmit power, while we lack the TD-H3's TX power figure, so direct power comparison isn't possible. The TD-H3 is notably lighter at 245g versus 299g, a meaningful difference for pocket carry.

Owner feedback slightly favors the TD-H3, with a 4.4 rating across 534 reviews compared to the GA-510's 4.3 from 602 reviews. Both show strong buyer satisfaction with minimal practical difference. Price heavily favors the TD-H3 at $32 versus $36, giving you the higher-scoring radio for less money.

The single most important differentiator is the TD-H3's weight and lower price, making it the better value proposition with comparable user satisfaction. Buy the GA-510 if you specifically need confirmed 10W output and can't find the TD-H3's power spec. Buy the TD-H3 for most users seeking a lightweight, budget-friendly option with strong owner reports. We recommend the TD-H3.
