Although the government has conventionally used jamming at its will, the personal use of jamming has become a deadly issue, with $100,00 fines per incident, for jamming cell phones or GPS devices. For the scoop see Paul Thurst’s “Engineering Blog.”

The GPS jamming, I see no reason why that should be an issue either, especially when big brother has nothing better to do than to constantly monitor innocent civilians just going about their daily business. Big brother should mind it’s own business and take care of business and get this country’s economy back on track and clean up DC instead of being infatuated with knowing every single bit of every person’s daily routine.
As the article points out, gonna be one heck of a task to try to track down these jamming devices or prevent them from being obtained by those who want them.
As long as there is a demand..there will always be a source.

Total posts : 45366An engineer friend who now owns a station told me a story in the 1970s about a jamming device he made for his girlfriend.
She had a son who blasted the acid rock music from a particular FM station and she couldn’t stand it. Like many kids, the son was willful and uncooperative and his music was forced on the household.
The engineer built an FM transmitter into a metal band-aid box with a 9-volt battery and a single on/off switch. When the music was too much to stand, the mother turned on the band-aid box and sweet silence filled the house.

Total posts : 45366Last year we had this very unsocial neighbor who used to crank up their stereo at night and kept my wife from getting her sleep. On several occasions I would go next door, knock and kindly ask them to please turn down the music because my wife is sleeping. More often, they would
just say ok and shut the door, and the loud music would continue.So being an engineer myself, and with plentiful transmitters on hand to play with, I decided to do something about it.
At first, they were blaring a thrash metal rock station, that was easy to silence…but then they would put on a CD or some other audio source and blast that.
Well I had a simple fix for that too.
I took out my 400 watt MW linear from the X closet, connected that into my LPB AM 25 low band TX, ran the output through a home made inductor coil, and tied that to the chain link fence separating the two properties.
Then fired it up.
The next thing we heard was a very loud THUMP from their speakers, and then sweet silence.
Never had a problem since.

Total posts : 45366the answer to cellular jamming is to permit private, commercial, and municipal use of captive cellular portals that permit outgoing/incoming calls to a 911/psap but disallow any other type of calls. it won’t jam emergency services radios or emergency cell calls but will disallow regular cell phone use in theaters, public transit, churches, etc.

Total posts : 45366Yes that is the way to have it set up instead of just jamming out the entire system. But even with allowing for portals to emergency communications, people are not going to go for that at all because it would seem like it would be keeping them from communicating with family, friends etc…may even get some resistance from free speech groups.
Technology…it’s wonderful, it makes our lives a little better, but it can also make life miserable when used and implemented improperly.

Total posts : 45366Uh-oh! Maybe I shouldn’t bring that up.
Anyway, yep, being a Taxi driver, we all use cellphones because we self-dispatch. Small area, income absolutely will not support anything like a central dispatch system. Radio comm on the island is even worse than cellphones (neither is capable of full coverage), so we use them all the time, even dispatch backup drivers.
But we all use Bluetooth headsets … it’s the law.
A local store tried to use a cellphone jamming device inside the store, but when they found out customers were complaining, couldn’t talk to kids, husbands, wives, about renting a movie, or what food to buy, the customers just shrugged it off and went somewhere else. The store was alienating customers and losing business, cutting its own throat so-to-speak.
I also mentioned, in my case, it could be considered restriction of business. A week later, the cellphone jammer was gone.
Sooner or later, some semblance of common sense has to happen on both sides of the equation, or else there will be damage.

How about a professional jamming service, “We accept government contracts.”

Total posts : 45366In college, the kid in the room next
to mine had his radio up against his
wall. It was not that loud, but he would
play it at weird hours sometimes. The
dorm walls were not that thick. So
sometimes when I wanted to sleep,
– on the other side of the wall –
I wouldn’t be able to because his
radio was on.The college was in Providence, RI. But
the FM station he listened to was in Worcester, MA,
some distance away. The station’s signal was
weak in Providence – it was near the edge of
the coverage area.I only did this once. He had the FM station on and
I really had to sleep, because I had a morning exam
at 8:AM. So I took MY radio, and tuned
it until the local oscillator signal was on top of the
Worcester, MA station. Silence. Just to be sure
it was really my radio that had done the trick,
I turned my radio off. The music started coming
through the wall again. I turned my radio back
on, and the music disappeared again. Then I turned
my radio off and on one more time to repeat the
effect. I heard some movement through the wall –
something was happening next door. Then I heard
a “Click.” That sound I heard was him turning his
radio off. He had had enough of his radio playing,
not playing, playing, etc.I can’t believe I actually heard the off “click” sound
right through the wall! That dorm was a noisy
place with thin thin walls.Then, I went to sleep, got up, went in to the 8:AM exam,
took it, and received an F for the grade.Actually, I’m kidding! I really don’t remember what the
grade was. It probably was a D. Those college days
were not good ones for me. But I eventually pulled
things together and everything turned out OK.Best Wishes,

Total posts : 45366With interesting instructors and good subjects college can be a very enjoyable experience. I think the trouble begins with dorms. Living in a group situation can turn into various shades of party.
If possible, live at home or in a private apartment when attending college.
I hear there are jammers in some dorms.
