Scanners and public safety professionals have had a turbulent love/hate relationship over the years. While many public safety professionals (me included) started off by being scanner users, many of these same people have had some serious issues with other scanner users. From so-called “cop-watchers” harassing police while they try to do their jobs to burglars listening in to avoid arrests and those that actively interfere with radio communications to some more innocent guys standing behind the caution tape listening in, the interactions can be difficult.
Not all the time, however, are scanner users the bad guy. Sometimes they can actually be a real help. Here are a few instances I have seen over the years.
Having the AVLS Blues:
Back in the 80’s, there wasn’t the widespread availability of GPS like we have now. Back then if you wanted to track your police cars you needed to install an AVLS (Automatic Vehicle Location System). These usually transmitted a beacon signal that was either tied to some sort of location device (early GPS or even older technologies) or used fixed receiver sites for triangulation.
One town in the south suburbs of Chicago had one of these systems and it transmitted short data bursts on their old dispatch channel, then used for car-to-car and secondary use (as many VHF channels were after most suburbs switched to UHF T-Band in the 70’s). This was not really a problem for them as they used PL for voice traffic and none for the data. The problem arose when the radio shop apparently wired the AVLS system into the radio of at least 2 cars incorrectly, sending the data to the selected channel instead of steering it to the desired channel. Most of the time this wasn’t an issue, but some guys would set the channel switch to ISPERN, the statewide emergency police channel on 155.475.
Now suddenly ISPERN was getting inundated with these data bursts. They would start most days at 3PM and stop at 11PM. Of course, us scanner guys knew what was happening, but we had to prove it to solve it. One of us lived close by and recognized the data bursts as the same used by a nearby town’s AVLS system so we met up down there and staked out the police station. We got lucky the third night and started hearing the data come up on ISPERN, we then were able to pinpoint it to the specific car.
We went into the PD, spoke to the watch commander and explained what we found. He was skeptical but after a couple of us identified ourselves as police officers from other towns he relented and went out to the parking lot with us. We showed him the car we thought it was coming from and sure enough the radio was selected to ISPERN. We shut that radio off and no more data. Turned the radio back on and there was the data again.
It turned out that the officer assigned to that car may have figured out that his location would not be shown if that radio was selected to ISPERN. We were asked not to say anything for a while and the Watch Commander had that radio fixed shortly thereafter. He called a week or two later and let us know that the officer assigned to the car was spending quality time with a girlfriend outside his assigned beat and that that issue was now resolved. We let the State Police district there now what we found, and they were thankful it had been resolved.
Another town way up north had a similar system that they decided to use their town’s Public Works channel for. The problem was they never bothered to tell PW about that. It wasn’t a problem on night shift but during the day PW was torqued off when they started hearing this data, it was strong enough to cover their voice traffic. They had no idea what was happening until one of their employees mentioned it to a friend who was a scanner club member. He asked around and some of us quickly figured out where it was coming from. Eventually PW added PL to their channel and that helped somewhat. As for the relationship between the police and PW, I think it didn’t recover soon enough, I had heard gossip on the grapevine of tensions for several years after this.
Gypsy tow trucks and “Sandra”:
Another user of the GMRS channel we used back in the 1980’s was a gypsy tow truck operation on the North Side of Chicago. Ever hear of the “Lincoln Park Pirates” (Lincoln Towing), infamous for towing legally parked cars or even occupied cars for ransom? These guys made Lincoln Towing look like polite kitty cats. They would talk about jacking cars off the street and falsifying the paperwork to say they were in their contracted lots, hiding around the corner with spotters to pounce on cars parked in or near to the lots and other nefarious activities that would make even a politician blush.
Why would we bother going after these guys? Well, for one, they could swear up a storm. Such foul language would make a Marine quiver. This is a family story so we will leave it at that. Second, they were running a totally illegal operation and preying on people. They openly talked about grabbing cars off the street to claim they were in a client’s lot, how they would break into the cars and steal valuables as well as other illegal activities. Third, they had no license for the radio system and that made us mad.
We were able to find the trucks soon enough, but they were (illegally) unmarked and the license plates were illegible (likely on purpose). A friend who worked for the State Department of Revenue searched state records and could not find any business licenses for them, and (in the days before the Internet became available to mortals like us) we spent hours searching phone books, city records and other records trying to get a hint who they were. We could find the parked trucks occasionally and would see them with a victim, but we couldn’t find their lot or shop.
One point of order here: A couple of us were cops or other law enforcement employees. We had contacts in several layers of the state and city governments, including the regulatory agencies governing towing and recovery companies. They were very interested in these guys!
The apparent patriarch of the family business would call out the name of whom we finally deduced was his daughter by yelling “Sandra” in a very distinctive eastern European accent. She would send them on calls and coordinate spotters working the lots they trolled.
For over a year they defied probability and evaded identification. Many nights were spent by MRG (Metro Radio Group, our CARMA-affiliated GMRS club at the time) members trying to track them down and eventually a year or so later they were found at a former gas station on the far North Side of Chicago.
When we finally did catch up to them, we took copious notes and pictures and even some video. Remember that this was before the days of smart phones, video cameras were huge and expensive, photographs were done with film and voice recording was done in cassette tape.
Some detailed sleuthing and a certain amount of stalking eventually turned up home addresses for the various family members. A few letters sent with incriminating evidence were sent and they were requested to remove themselves from the planet, or at least the frequency. One bright and sunny winter’s day they up and disappeared, never to be heard of again. We never found out for sure if they just moved to another channel or maybe even shut down the business. As far as we were concerned, they were off the frequency and that was all we cared about. Our friends in the state government were sent what we found but we never heard back from them.
Ambulance Chasing:
In the mid 1980’s the 7 GMRS interstitial frequencies sandwiched between the regular pairs were not authorized for any use. While later on (1989) they would become legal for low power use by GMRS licensees and later by FRS users, at this time they were not authorized for anyone. Occasional simplex use would be heard here and there but for the most part they were quiet. Then one day a couple CARMA members started hearing what sounded like car-to-car traffic of a fire department or ambulance service operation on a repeater on one of these interstitials. A few hours of DF’ing found that the repeater was located on a tower in Arlington Hts., across from Buffalo Grove High School. This tower was the site of a high-power FM radio station (WYEN, “Request Radio 107.9”) as well as several land-mobile antennas. One of these antennas was being used for this illegal repeater a couple hundred feet up the tall broadcast tower.
Traffic on this repeater was recorded onto cassette, photos taken and eventually the mobile units were found. They turned out to be a local private ambulance service, using it to chit-chat about the runs they were on and the traffic conditions they dealt with. CARMA members who had contacts in the FCC provided the information collected, including the recordings, photos and activity logs. A few days later the repeater disappeared, never to be heard from again. According to the FCC Field Office in Park Ridge a fine was levied, and the repeater owner was advised to remove the repeater or have it confiscated.
