i have performed a micro-jam in real life! i was using the cordless phone and turned on the microwave and then the phone got all messed up and they couldnt hear me and then wen the microwave shut off it was normal! that truely was KR style and it worked.

micro jamming

I've been in the field of electronics for over 30 years now, and I've never heard of "micro-jamming" in the real world as it was used in Knight Rider, but jamming obviously does exist. I think in this context, it refers to a tightly directed beam of interference, not unlike the parallel (collated)beam of a laser. Where it's possible to use parabolic dishes (terrestrial and satellite-platformed) to isolate a small point by using peripheral nulling, it would be very hard to focus the footprint of a noise field to a small area. Just my observation. Weather radar uses fan or pencil beams to scan, but this is a scanning function, not a jamming function--two differnet things entirely. My point is this..you can use jamming, but if you do, you will affect others in the nearby area. Perhaps you could loosely use the term "micro-jamming" to mean "pencil-beamed" jamming. But this would only work if you knew the exact frequency in use by the target. There is also saturation jamming, but that is a very inefficient and dirty way to jam and typically takes much more power.

Well, the "microwaves" from the MICROWAVE does scramble the reception on the phone.

A micro-jam can also be preformed by a cellphone. Just text or call someone on the cell and stand near an ordinary telephone. The phone will pick up the noisy interference signals of the cell (quite annoying really if someone is using the telephone).

I sometimes hear "pops" in my computer or answering machine speaker if my cell phone is too close to either one of them. When I first discovered it, it was going through the answering machine and I couldn't figure out what that was. I thought the answering machine was possessed. :lol:

saturation

yep, the two above cases are "saturation"-type jamming. Simply overwhelming a local area with a lot of power.

Annoying nonetheless. :lol: Something I don't tend to practice on a regular bases. ;)

If I'm on the computer and have my cell phone next to it, I know when I'm about to get a call from interference on the speakers. Microwaves scramble household items among other things, imagine their effect on the human brain as a large percentage of the world emits cell phone microwaves directly into their heads every day, including myself. :x

Or sitting in front of a computer monitor. Maybe not as much radiation these days but back in the 80s I would sit for hours, even until sunrise in front of a computer monitor. Also not the greatest thing.

Then there's the famed telephone/electrical wires, appliances, etc. It's everywhere. They won. :twisted: ;)

Quite right, which is why I use a Stealth Radar Shield on my cell phone.

kitt-x - Where can I pick up one of those and how much do they go for? I don't feel like developing a brain tumor in 20 years. :?
