Radioddity GD-88 vs TYT MD-UV390

The GD-88 edges ahead, but this is genuinely close. The single most important differentiator is feature set: the GD-88 adds APRS and GPS capability plus higher transmit power, while the MD-UV390 offers better weather sealing at IP67 versus IP54. Owners report similarly positive experiences with both radios, giving the GD-88 3.9/5 from 92 reviews and the MD-UV390 4.0/5 from 142 reviews.

The GD-88 costs $34 more and adds functional features that matter for specific use cases. The MD-UV390 costs less and delivers the core DMR handheld experience with tighter weatherproofing, though we lack its weight specification. Buy the GD-88 if APRS, GPS, or the extra wattage align with your operations. Buy the MD-UV390 if you want the lowest entry price for DMR, value the superior IP rating, or need minimal features done well.

For most operators choosing between them, the MD-UV390 offers better value given the minor specification differences and marginally higher owner satisfaction. Only choose the GD-88 if those specific features justify the premium.
