Radioddity GA-510 vs Radtel RT-860

The Radioddity GA-510 is the clear winner here.

The most important differentiator is the TX power specification. The GA-510 delivers a confirmed 10W, while the RT-860's power output is unknown. In a direct comparison between two otherwise similar radios, knowing your transmit capability matters. Both lack digital modes and advanced features, and both have no listed IP rating, so they're functionally equivalent on paper except for this gap.

The GA-510 also benefits from CHIRP compatibility for easier programming and a stronger owner rating. Owners report 4.3 out of 5 stars across 602 reviews for the GA-510, compared to 3.9 out of 5 from 139 reviews for the RT-860. The RT-860 is slightly lighter at 255g versus 299g, and costs only two dollars more, so weight isn't a practical advantage given the price parity.

Buy the Radioddity GA-510 if you want documented performance, CHIRP support, and what owners broadly report as satisfactory operation. Buy the Radtel RT-860 only if the lighter weight is essential and you can confirm its power output elsewhere, since that spec is missing from our data.

The GA-510 is the safer choice at nearly the same price.
