Retevis HA2 vs Retevis RA79

The HA2 is the clear winner here, though the margin is narrower than the price difference suggests. The single most important differentiator is APRS capability. The HA2 includes APRS functionality, making it significantly more valuable for location tracking and digital communication, while the RA79 strips this feature entirely despite costing one-third the price.

The HA2 justifies its higher cost through APRS support, which opens up modern amateur radio capabilities that the RA79 simply cannot match. However, the RA79 does offer CHIRP compatibility for easier programming, something the HA2 lacks. Both models frustratingly omit critical specifications like transmit power and weight, making full evaluation difficult.

The HA2 suits operators who want to participate in APRS networks and don't mind manual programming. The RA79 is best suited for budget-conscious beginners who prioritize ease of setup over advanced features.

If you plan to use digital location sharing or modern digital modes, spend the extra seventy dollars on the HA2. If you're a casual operator on a tight budget willing to program via CHIRP, the RA79 provides acceptable basic functionality. The HA2 edges out a recommendation for most users.
