Amateur Radio

[InbetweenDreams]

I think my biggest interest in this topic, is attempting to find the same (band?), (frequency?) cell phones use. Mimick(?) it or inverse it(?) with a powerful broadcaster to try and cancel it out .
that would be cool

could probably have a computer receiveing across a spectrum, constantly incrementing through. Once a signal is discovered decide the best counter signal and broadcast it .

Cell phones use 700 MHz, 800 MHz and something around 1800-1900 MHz and is completely illegal to listen to those portions of spectrum...However, it is all encoded and encrypted. All receivers in the US are supposed to have those segments blocked out, however a lot of the stuff from China isn't.

Now...

When I was a kid my grandpa had this old portable TV/Radio..



Well I found out if I tuned it to the highest channels like channel 83 I could hear people's phone calls...all sorts of tones and people talking, pretty neat... I was like 7-8 years old roughly I think at the time...probably heard a few drug deals lol
