Great stories! And a way that someone dealt with subwoofers!
StuMichaels' story reminds me of another incident. Our group had just moved from our old office area into an area of the building adjacent to a manufacturing line. The assemblers had a boom box that they played pretty loud--90's pop music, wafted through our cubicles. Well the same loud pop music got tiresome after awhile, and somebody got the idea of playing a little music of their own over their boombox using a high frequency generator, and modulating it with...Saturday Night Fever. So just as Celine Dione's It Was So Long Ago song would be getting to the "Baby! Baby! Baby!" part, you would suddenly hear this mysterious ba-da-ba-da-ba-da-da-ba... and Stayin' Alive would start up. "It's the Bee Gees again!", someone one line would frantically yell. Radio Bee Gees indeed! I guess it's better than an all Elvis station, though.
If just interested in near field jamming bias up a zener diode with around 10 mA. Connect it to a couple of Mini-Circuit MAR Series amplifiers via a cap. Attach the output of the Mini-Circuit amps to an antenna wire. It will make you the prize of the FCC but hey, it will shut up all those important cell phone conversations in the restaurant.
I had a chance to have a beer and meet Bob Pease at a conference here in Phoenix. We were discussing the boom-boom cars. He prefaced the discussion with "Well, of course it would be illegal, but I heard of this guy..." And went on to describe a neighborhood kid with a boom boom car and he would let it play parked. Approaching his dad did no good, so a circuit was built. A mic with a low pass filter attached to a spark gap transmitter and a very long antenna would clobber every TV and radio within a block. The interference 'seemed' synchronous with the bass track of that kid's car. He spent hundred$ adding filters and such. He finally turned it down when approaching home.
I used this trick on my high school electronics teacher who was attempting to repair a radio. I just grabbed a test oscillator off the shelf. Every time that he got the radio tuned to a station, I faded his station out. He finally walked away and "repaired" the radio the next day.
At a company I worked for in the early 1970s, they had an FM radio playing over the P.A. system. Unfortunately, it was controlled by the secretaries who liked 'elevator music'.
I fired up our high frequency generator with a length of wire acting as an antenna and tuned it to the station the FM radio was tuned to. I found that if I slowly changed the generator frequency, I could 'pull' the FM radio to a new station. Due to the radio's AFC, it would lock on the new station.
This would work for a few hours until a secretary noticed and would tune the radio back to the original station. Of course, I would then 'pull' it again.
This went on for a few weeks until, one day, I noticed that the radio was off. I asked one of the secretaries why there was no music. The answer: 'The radio kept changing stations so we sent it out for repair.'
As others have commented, jamming a licensed radio station is illegal.
Another approach might have been to build an audio oscillator, feed it into your own high-power audio system, aim the speakers at the obnoxious neighbor, and blast her with a 10 kHz tone at high volume until she called for a truce. Of course, earplugs would be needed to preserve your own sanity :)
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
