There are feed providers using rtl-sdr dongles, including me.
This might be a possibility. The learning curve looks fairly steep
The sdr Radio dongles are only about $35. It looks like two are required for a digital trunk system.
Is anyone using an RTL Software Defined Radio for the West Virginia SIRN network?
It looks like the sdtrunk software may work with SIRN:
DSheirer/sdrtrunk
So far I can't determine whether or not sdtrunk supports simulcast.
I may just buy two of these dongles and give it a try before buying a new scanner. I see that they can also be used as a spectrum analyzer. If I can't get sdtrunk working I can allways use another spectrum analyzer. Also, these will be a lot more portable than my old boat-anchor benchtop spectrum analyzer
