Jailbreak firmware now available for cheap digital walkie-talkie allowing DMR scanning
In the last years, DMR and MOTOTRBO (a.k.a. TRBO a Motorola Solutions branded DMR Radios ) has become a very popular digital voice mode on the UHF and VHF bands and the MD380 radio is the latest cheap DMR walkie-talkie to come out of China.
The question is, is it any good? The longer answer is slightly more complicated, and involves discussing the difference in price between this radio and other more expensive, but higher quality, radios. But i can tell you that a group of hams here recently purchased the Beihaidao DMR radio (also sold under brands like Tytera, KERUIER or Retevis) and have been having excellent results with them.
Every once in a great while, a piece of radio gear catches the attention of a prolific hardware guru and is reverse engineered. A few years ago, it was the RTL-SDR, and since then, software defined radios became the next big thing. Last Shmoocon, Travis Goodspeed presented his reverse engineering of the MD380 digital handheld radio.
