    I got my hands on the much-awaited Baofeng DM-5Rhttps://*************************/e/ir?source=bk&t=hamradiorev07-20&bm-id=default&l=ktl&linkId=b20281b5965a07ca3f704b19088d78d0&_cb=1476994480336 DMR radio today. The radio is based on the highly popular UV-5Rhttps://*************************/e/ir?source=bk&t=hamradiorev07-20&bm-id=default&l=ktl&linkId=8dec4a21f2bdeb1df99705bb07b2b37c&_cb=1476993911975 model (and its variants). At $70 US, it seems like a bargain. A big advantage over other radios on the market, is that it is dual-band. A big disadvantage, however, is that it currently comes as Tier I, which can be upgraded to Tier II.


    Here is the video, enjoy:

    I have a UV-5R that if you plug the programming cable into it, it makes it transmit. I have had one other person tell me they have the same problem. Anyone know why and what can be done?

    What is meant by "Tier I" (or Tier II)?

    They all do that, that's why the manual says to tune to an used frequency when programming

    Tier I can be thought of as DMR for FRS (not legal in US), SIMPLEX only. Tier II is higher power and repeater operation.

    when the UV-5R goes into transmit with the programming cable plugged in.... you didn't plug the plug in ALL THE WAY IN... I admit it is a tight fit but you need to push the connector in a little further.

    If your UV-5R or other Baofeng radio goes into transmit full-time when plugged into the programming cable, it may be because you have a Windows 6/7/8/10 computer which automatically downloads the "correct" Prolific driver for that cable. That driver won't work. You can try the site for an older version of the driver but don't have the computer c0nnected to the internet when you install it. Other than that, you can buy a newer programming cable with an FTDI chipset (on or elsewhere) which should work. 73!

    Tier I uses FDMA and is meant for a FRS like service overseas. Tier II is TDMA (multiple time slots), higher power and repeater capable.

    I have heard that the upgrade doesn't make the radio a true TDMA radio (duh, pretty hard to imagine the hardware would be capable of the quick TX/RX), it just makes it work in a software sense, filling in null packets on the second slot instead of actually turning of for 10 ms.

    Needless to say, using a non true TDMA radio will kill using the second time slot of the repeater you are on.
