Having purchased the Tyteria MD-380 and loading on as many contacts as I could, I found that it was limited to approximately 1000 contacts.  (I would have known this if I had read the description of the radio before purchasing.)   Now, this is probably adequate if you are using the radio for communication within a business, but I’m using this for amateur radio.  When I receive on it, I want to see the identification of the person talking.  Therefore, I need about 100,000 contacts.  The way this radio comes from the manufacturer will not do.

Fortunately, there are some hams working on a solution.  This is a popular DMR radio and some smart fellows have banded together to reverse engineer the firmware and improve it.  It now supports a lot more contacts (I haven’t found the limit yet), and it has other features that will make it way more useful in amateur radio.  And it’s free!

You can get the updated firmware at MD-380 Tools: https://github.com/KD4Z/md380tools-vm. It includes everything, even the ability to modify the firmware yourself if you are so inclined.  This allowed me to put 70,000 contacts in the radio.  That’s just what I needed.

There is another codeplug editor developed by Dale Farnsworth: https://www.farnsworth.org/dale/codeplug/editcp/, but I have not been able to get it to work correctly.  You need to install the MD-380 Tools firmware, and then you should be able to manage the contacts separately.  I have not been able to get that to work.
