Radioddity GS-10B vs Radtel RT-880

The Radioddity GS-10B is the clear winner here. Despite both radios lacking modern features like DMR, APRS, and GPS, the GS-10B delivers better performance at a significantly lower price point.

The single most important differentiator is the confirmed 8W transmit power of the GS-10B versus the unknown output of the RT-880. Combined with the GS-10B's substantially higher overall score of 65 versus 52, this suggests meaningfully better real-world performance. The $34 price difference further tilts the scales decisively in favor of Radioddity's offering.

Both radios are barebones units without computerized programming capability, limiting their appeal to users who prefer manual frequency entry. The GS-10B suits budget-conscious operators who want solid baseline performance for simplex communication and basic repeater use without breaking the bank. The RT-880 might appeal only to someone with specific niche requirements, but those aren't evident from the specs provided.

Buy the Radioddity GS-10B. It offers the better value proposition, documented power output, and superior scoring. Unless you have a compelling reason to choose the RT-880, spending less money on the higher-performing radio is the logical choice for any amateur operator evaluating these two models.
