I want to know how to make a signal jammer. Thanks! :)
my roommate is jamming 10.1 on my t.v. which is CBS so I can't watch football, how do I stop it now and make sure it never happens again.

Do you mean an IR remote jammer? Or a jammer to jam over-the-air terrestrial TV signals? I suppose it could be you want to jam satellite TV signals? Anyway, if you feel up to it, some disambiguation would be nice.
Also note that if you mean jamming radio signals, that's generally illegal... and because you have to broadcast to do it, you're announcing your location every time you turn the device on.
It's only illegal if you don't have a license to use that part of the spectrum. So I wouldn't say that it's illegal in general. If that were true, then no one would be broadcasting any TV signals of any kind, because it would be illegal to do so. Technically the license holders are jamming everyone else who might want to use the spectrum, but did not pay for a license. More importantly, is this right? Does the FCC own the ether? Or does it belong to the people who live in the same space where the radio waves travel? And what do these various government regulatory agencies the world over, what do they do with all the licensing fees they collect? If the electromagnetic spectrum belongs to the people, then I think the FCC should be sending me a dividend check, commensurate with the amount of space I inhabit filled with other people's radio waves, i.e. my share of the space where officially licensed radio waves are allowed to travel. That would really be the equitable way to do things.
The FCC does "own" the ether, and license fees are handled like other taxes... so they _are_ sending you a check, or more accurately deducting it from the bill the government sends you.Even with a license, there's the question of what kind of license. Low-power consumer equipment is almost all under licenses which require that it not interfere with anyone else's use of the same bandwidth; if your device creates interference that anyone notices, it's your responsibility to repair it or replace it so it doesn't. A jammer, obviously, would blatently violate that. As you increase power, you're under increasingly stringent requirements to negotiate who gets to monopolize what frequencies BEFORE you turn the power on rather than waiting for someone to complain.
I know they use some of it to police users who are infringing on the rights of those who paid -- like when truckers or out-of-country construction crews bring in their mobile radios and talk over our ambulances on legacy radio repeaters...simply because they don't know its in use.
Related to your comment, the switch over to HDTV opened up radio/TV frequencies for use by police/fire/military. It's a over simplification of the reasoning behind the government forcing it but I think you get what I'm alluding to.
