I've been playing around with RTL-SDR and Unitrunker attempting to get a police scanner working. I followed the tutorial here: https://sites.google.com/site/policescannerhowto/
Everything works as expected until I run Unitrunker and try to add the two receivers. When I do so I only see the top section as seen in this image:
This happens when I add the control receiver as well. In the tutorial and all the other examples I've seen all over the net, there are many more fields underneath those which are necessary to get things working. I know the RTL-SDR receiver is working, I am able to tune to various radio stations with SDR#.
What could be causing this? And what steps can I take to fix it?
