In case you don't follow the Unitrunker V2 development it now has a direct receive feature for my Airspy Mini SDR. This means I can track the system directly with UT and it will also voice follow the system w/o the need for 2nd dongle or other software.
It's pretty stable so far and seems to work pretty good. The only requirement is that it has a good, stable RF signal from your dongle.
To get the latest beta versions you need to join the UT google group but here's version 73 in case you want to try it for yourself:
