No current ability to track trunked radio units, though arguably thats 'just a software problem'.
I have one and have found it to be quite easy to hunt down ham repeaters that you can get to transmit more or less non-stop... but relatively hard to use for intermittent transmitters.
I need to see if I can figure out how to plub in my GNSS compass output because inferring orientation from motion requires an awful lot of moving around and is less reliable than I'd like.
also the "kraken" may be $700, but there was kerberosdr/hydrasdr which was much cheaper. Furthermore, trunking is usually done within the bandwidth of a typical SDR so it doesn't really obfuscate it as much as one would think. Also i bought one; not to find repeaters, but to find trolls who were using repeaters. I'd monitor the input frequency to the repeater, apparently the same as mitnick would.
there were trunking scanners in the late 90s / early 2000s, as well. my neighbor had one.
