Here is a short video starring the LimeNet Micro being used (tested with SDRTrunk) as a DMR tier III BTS in the 430 MHz amateur radio band:

Just a small note, the hardware is being used here as a peripheral instead of standalone due to the compute resources needed for this.  
The trunked radio implementation is based on MMDVM and is entirely open source, will be released at a later date this year.

And this page: [Implementation of a DMR Tier III trunked radio Base Station Transceiver in Software Defined Radio](http://qradiolink.org/DMR-tier-3-trunked-radio-BTS-software-defined-radio.html) now contains a more detailed description of the DMR tier III base station as used with the LimeNet-Micro and LimeSDR-mini hardware.

This is very cool indeed. Thanks for sharing details!
