DMR radios to avoid!

There has been a new trend lately of the Chinese radio manufacturers making DMR radios that don't do TDMA. TDMA is the pulsing the radio does that actually makes it transmit only half the time on the channel, allowing another user to transmit in the other half. This is what allows DMR repeaters to repeat two conversations at once. TDMA is a fundamental part of the DMR standard.

These new "DMR" radios that have only come about recently are unable to do TDMA. They are being sold in many cases as tier 2 DMR radios, which means they should be able to do TDMA to use repeaters properly, but they cannot. (See my video for an explanation of the difference between the tiers).

TYT MD-380 Talkgroups use question response video

In response to people asking me the same question a few times on my TYT MD-380 programming for amateurs video, I have made this video. I do read your comments on videos so don't be afraid to ask a question. If it's a common question I'll be happy to make a video about it so I can explain it to everyone.

TYT MD-390 Firmware update

TYT MD-390
I managed to get hold of the latest (for the moment at least) update for the TYT MD-390. The version should be D013.009. Download here.

By the way, if you're new here and have come here via a search engine, I have a YouTube channel where I make videos about radio stuff, particularly DMR. If you're interested in DMR then you might like my channel.
