Yes, but they are not cheap. The comment below using SDR would be much less expensive, but I don't know a lot about digital trunking with an SDR unit.

Here is a standalone portable unit: https://www.amazon.com/Uniden-BCD436HP-HomePatrol-TrunkTracker-Programming/dp/B00I33XDAK/ref=sr_1_1?ie=UTF8&qid=1549520011&sr=8-1&keywords=digital+trunking+scanner+p25

It's about $50 cheaper if you get a base unit, but still crazy expensive. If you do happen to invest in one, there is software to program it easily using data from radio-reference.com. It's called freescan.
