Any plans to implement ThumbDV for DMR capability?

Change seems to be in the air...

You can buy a ThumbDV at the Flex store now, which would only be of any use with SSDR 1.50, so I assume that its release is "imminent".

The primary purpose is primarily to encode/decode D-Star these days. Any plans to use the Ambe chip, it contains, to implement DMR/Mototrbo capability in the Flex signature series?

I have both types of radios already if you need a beta tester...

    The codec is part of the equation. The second part is the on-air modem and any other code to support the mode. With D-STAR this required an external app to handle callsign data for example. We are making the modules open source so that others that are so inclined can expand on what we've done. We may also do more just depending on popularity, demand, etc.

    So, anyone else out there wish to show interest in a DMR module too?

    DMR would appear to be getting very popular recently, in light of the low priced Chinese HTs with this capability appearing in the market??

    Perhaps we could cajole FRS into implementing the first all mode Digital Voice transceiver while all of the others remain little more than vaporware???????

    Once more people get comfortable with writing waveform and other utilities that implement the API and FlexLib, this stuff is going to take off big-time!

    I wish I was a better programmer.....

    DMR is TDMA and requires precise T/R timing in order to function correctly, so it wouldn't be a very simple proposition. Meaning, IMO it's doubtful that any old transverter would work well enough in this application to make it worth the effort.

    I'd rather Flex spend time continuing to add HF - related functionality.

    I just emailed the smart guys at Downeast Microwave if their line of transverters could handle the 30 msec packet bursts of RF that TDMA required.

    It will be interesting what they will have to say (unless it's just "Dunno... never tried...").

    An Amateur can dream, right!?

    I don't know how much you know about DMR. I've heard they're a lot pitfalls, I could be wrong.
