Retevis A3 vs TYT MD-UV390

The TYT MD-UV390 is the clear winner here. The single most important differentiator is DMR digital mode support: the MD-UV390 includes it while the A3 does not. Beyond that, the MD-UV390 offers an IP67 weather rating, providing protection in wet conditions that the A3 lacks. Owners report higher satisfaction with the MD-UV390 (4.0 out of 5 from 142 reviews versus 3.6 out of 5 from 31 reviews), suggesting more users found it met their expectations. The MD-UV390 also specifies 5 watts transmit power while the A3 lists this as unknown. The A3 weighs 286g but we don't have the MD-UV390's weight for comparison. At only an 11 dollar price difference, the MD-UV390 delivers substantially more capability. The Retevis A3 might suit someone seeking the absolute lowest entry price with no need for digital modes. The TYT MD-UV390 is the better choice for most operators wanting DMR capability, weather sealing, and stronger owner confidence within an affordable budget.
