They can definitely track the person doing it. Ham radio operators are trained how to do this. Its called foxhunting. You get a group of guys together from that area. All you need are radios receiving the signal. Figure out what area the guy is in, then break out your maps and compasses and triangulate the signal. Its actually easy to do and fun. I used to participate in foxhunts many years ago with the ham radio just for fun. Being that it is on analog frequencies makes it even easier for anyone to foxhunt this guy. It makes me wonder if this is still the same guy from back around 2013 when LCD was getting messed with by the guy in Mass. He had a boafeng radio and was causing Public safety calls to be diverted and putting out fake calls. Its hard to get hams out there to help with this because most hams are off on HF frequencies talking around the world. They dont care for VHF/UHF communications (where this guy is sitting causing a load of it for public safety). Its one of the reasons I gave it up. The sad part about all of this is that the FCC doesnt care one bit about this. Until it goes on too long and/or a life is lost, they wont bother catching the person causing issues on the radio. Ive seen it happen several times in CT before.
Being a HAM as well, one or two members of the club I am in have been asked by AARL/FCC to triangle some offenders on HAM repeaters and such as well.
In addition to that guy in 2013 messing with either LCD or NWD and diverting calls, there was another before that that used MURS frequencies that Walmart uses and broadcast some bad stuff over one of the Walmarts in the state's radios causing a panic and evac of the store.
Both of those were met with full force of the law quickly. This person.. burping into the Mic... may be a disruption, but it's at least not causing panics or redirecting public safety calls. Priority is low.
I enjoy listening to the scanner at home myself. I also know that sometimes people will carry a scanner during commission of a crime to keep ears on the pd, thats a big reason why I have my opinion. Also because I see private information get posted all over facebook a lot, which always starts with "I heard this on the scanner"
I use it to know what's going on around me. Lucky for me I set up stationary scanners in the towns I frequent so I have ProScan record and also broadcast over the internet PRIVATELY (private link, no public feeds). Oxford, Woodbury, Southington mostly. I turn it on if I hear sirens near me. The other week myself and 10 others, both on the sidewalk and crossing the road on the Farmington Canal Trail on Center St, were almost run over by a car doing 50+ the wrong way on Center St. Ears on quick and heard there was a stolen car that matched the description that took up on them. Flagged down an officer, pointed them in the right direction, listened and that night they had the car back and got the driver that matched the description a bunch of us saw. Also we had gunshots in my area one night 2am last summer, twice actually, in little old Woodbury. One was defensive to scare off someone trying to steal a car, but resulted in an officer driving up our long set back driveway at 3am with full search lights, my ProScan recordings helped figure out why that happened and happy they did. The other was some actual mischief by some kids, but itut my mind at ease knowing what was going on and they were on top of it.
I for one am happy they have encrypted tactical channels, but dispatch is in the clear on CLMRN. On the old Smart Zone II system the Emergency Response Unit TalkGroups were in the clear, the states SWAT essentially. There were things being broadcast on there in the clear no one should be able to hear that could have put the officers in danger, positions, views, etc. These TG's are now Encrypted, as they should be being their tactical channels. Each CSP also has their own encrypted channel for Personal ID transmission as well and I've never seen them used, but can be for operations in a quick pinch. Waterbury has their VICE TG encrypted, dispatch in clear. I think these all have a good balance of public safety and safety of responders with this setup. Encryption for the sake of encryption, especially on dispatch channels, is stupid and lacks government transparency, but for tactical channels I fully support it.
