The problem always started when I tried to use the UserDB. Anyway, after additional research I found that the solution is to give the radio a new software. For some unknown to me reasons the VHF version is equipped with only 1MB memory!!! Anyway, most DMR users will grab UHF version so it is not a problem. First of all I found out that the UHF MD380 / 390 has got only 16MB memory. We talk about the massive 198.000 (August 2021) database of all world’s DMR users! Imagine, you do not know who is talking on the radio, you look at the display and you see all info as shown on the picture below – it is very nice, isn’t?Īnd this was the main reason why I decided to resolve the problem. And just to make sure, we are not talking about contacts created ourselves during programming the radio. Currently in August 2021 the amateur ham radio user database is around 198.000, so obviously the standard radio’s software won’t be able to display the station’s info. One of its problem is the limitation of the digital contacts which can be created. However, the radio’s firmware is a bit rough. They are identical! 🙂 For radios like Hytera or Motorola you need to pay much much more.
All the mods below will also work for a clone radios Retevis RT3 and Retevis RT8.
The Tyt (Tytera) MD380 (or MD390 which is “water proof”) is one of the most popular amateur DMR radio, as it costs only about £80.
