Tytera MD-UV380 2m/70cm Radio for FM & DMR

I already owned a TYT MD-380, 70cm analogue and DMR radio but I recently bought a MD-UV380 which does both 2m and 70cm analogue and DMR. It also has other improvements.



The MD-UV380 is well built and robust. It looks very similar to its predecessor. Differences include:

  • Covers 2m and 70cm.
  • Zones and Scan Groups can have up to 64 channels.
  • You CANNOT use Toolz, software that added functionality to older TYT radios.
  • You need different software, from TYT site, to edit, upload code plugs etc.
  • I have not figured out how to upload the world-wide Contacts database but individual contacts can be added as required.
  • Zone members can be added from radio.

Other code plug editors, such as the one by G6AMU are easier to use but the current version will not talk to MD UV380, so edit in G6AMU save and upload with Tytera software - a bit of a pain but not difficult. 


A word to the wise! Save a backup copy of your existing code plug BEFORE you edit it so if you get in a muddle you can revert to a known, working version!


When you get your 380 it’s just a paperweight until you load a code plug to define channels etc. You can write this yourself or ask online or at your radio club for a ready made version suitable for your area. A major drawback of this radio is the very poor user manual and no ‘Help’ file with the TYT software (or the G6AMU editor). So, although I like this radio it is not great for anyone unfamiliar with DMR, unless you have a mentor to help you. 


On the air, the radio works well and, once I had figured out how it works, it is fairly easy to use. The display is clear except in very bright light. Audio reports of my transmissions were good and received audio clear. Battery life is good and don’t forget DMR transmissions are more economical than FM as the duty cycle is 50%.


In summary, this is a great radio and currently sells at a good price. Its documentation and software help files need to be greatly improved.

FM Switch Off - OFCOM Response

In August ast year I published a post on the governments plans to switch off FM radio in UK(http://m0bgr.blogspot.co.uk/2011/08/dab-radio-switching-off-fm-and-am.html ). At that time OFCOM was holding a 'consultation' and they have now responded to its findings. Their report is at http://stakeholders.ofcom.org.uk/binaries/consultations/dab-coverage-planning/statement/statement.pdf .

As predicted, OFCOM have swept aside all objections to the plan and asserted their previously held position that DAB is very wonderful so we don't need FM (subtext, the government have told us to sell the spectrum, just like they are now selling part of 143MHz - 156MHz band).

I have nothing against DAB radio, but I do not see it as a replacement for FM. It is technically inferior in many ways, particularly its coverage charateristics. DAB is based on obsolete technology and UK will have to adopt DAB+ or DRM at some point. DAB and FM do not use the same spectrum so, unlike the TV digital switch over, there is no need to close FM to allow expansion of DAB. Reading the consultation responses, the radio industry seems distinctly like warm about  switching to DAB.

If you use FM radio in UK, please let OFCOM know what you think.
