I was wondering if when you pick up lojack with close call would that mean a vehicle is getting stolen or a stolen vehicle in the vicinity around you?
The Lojack transmitter is activated when a vehicle has been stolen.you pick up lojack with close call
Thanks for These links. I never have looked into LoJack monitoring because I just assumed that it was probably a signal up a few gigahertz at least. I do find it interesting that there is only one frequency in the United States used for LoJack.
I’ve always scanned LoJack frequency in my normal scan list and in 15 years, I’ve found 2 stolen items... a boat and one of those BobCat earth movers.
Turned on my scanner both times and it stopped on LoJack with the tell-tale squawk. So decided to investigate. Here’s how I tracked them down with a Uniden 396T, then 396XT
Put on a low gain UHF (yes UHF) with squelch set to 0 and went driving around with the attenuator turned off. When the signal got full strength, turned on the attenuator till the signal went full strength. Removed the antenna and turned off the attenuator till the signal got close or full strength. Attenuator turned back on went walking around until the signal went to close to full scale. Now I’m in a construction site building a few homes. Now I put a 50 ohm SMA terminator on the antenna port with a 1/32” hole drilled through the side metal shell. This acts like a beam antenna where the small hole is. Using my body as a RF shield and the 1/32” hole pointed away from my body, I went around all the heavy trucks and machinery and got a strong hit on a BobCat. Put on another 50 Ohm terminator without any hole and there was no question the BobCat was emitting the LoJack signal.
Called my local PD and they showed up, quite skeptical honestly. They ran the serial number and it came up stolen from another state 3 weeks earlier. Asked how I got a LoJack receiver, I showed them my simple scanner and antennas used to hunt it down. Long story short, they staked out the BobCat and arrested the owner of the construction company and the BobCat was returned to its owner. Same thing happened to a docked boat I got a hit on 7ish years later.
As far as I know, no PD within 100’s of miles has a LoJack receiver in their squad car.
Most people are going to hear the base stations only...It inly worked for XTS3000 as he was in a location where that is not true There are states with no base stations but along the east coast, for example, each state has at least several base stations tranmitting every 64 seconds. LoJack is now used primarily to secure items other than cars--particularly industrial equipment and sometimes even boats. At my location (Virginia), I can hear 8 base stations, a different one every 8 seconds, until the pattern starts up again at 64 seconds. The nearest base station (high power and licensed to the state police, as done in most states, and among the other antennas on a tall tower) is 2 miles from me.I’ve always scanned LoJack frequency in my normal scan list and in 15 years, I’ve found 2 stolen items... a boat and one of those BobCat earth movers.
Thank you for that information and also for the link. I was just about to start looking on YouTube to see if there were any examples. I don't guess we can actually decode the signal but I'm guessing it will make a different sound when it is receiving a signal from a stolen or tripped vehicle. Thanks again for the help full information!
You are hearing one or more of the towers.I'm just put in the 173.075 frequency on my SDS200 and I get a squawk about every 10 seconds or so.
