A few customers have reported an issue with the clock that can be resolved by using the programming software. If programmed through the keypad, the clock may lose time, however, when programmed through the PC using the MD-390 programming software, the clock keeps time with no issues. We tested this with our units for an extended period and it does work.
The MD-390 is a single band radio. TYT plans to manufacturer two models, one UHF and one VHF, however, it is currently available in UHF only. We currently list the MD-390 as a UHF radio.
It is confusing because TYT lists both frequency bands on their product sheet and in their user manual, but does not specify they are two different models. They do list the bands and frequency ranges on separate lines, and although they don’t state this is a dual band radio, they don’t clearly state these are two different versions, either. It confused us too at first and we had to get clarification from TYT. We didn’t know this for sure until we received the demo units.
The radios are nice and they are a great price for DMR, but no doubt their user manuals and spec sheets could be better.
