How about a voltage comparator and a little logic. I'm not sure what kind of power one has at one's disposal inside of a mouse but something tells me if there is room for the logic it can be done.
Not on any bandwidth regulated by 47CFR97. Hams aren't allowed to obscure the meaning of a message (47CFR97.113(a)(4)), except in the telecommand of satellites and certain emergencies (by my interpretation). The idea is everyone who is listening should understand what you're talking about if they speak the same language, in fact we're not even really allowed to use 10-codes, we have our own system. Ham bandwidth is more for experimenting than implementing an email system (however doing that is a very cool thing). If we need to have lots of these email systems the ITU would have to set aside a chunk of bandwidth, and the FCC could make rules specifically for that purpose.
If you want to read the prohibited transmissions they are mostly here
.
Being a ham I know there are a lot of people out there who know a little bit about satellites (There are also a lot of people who know a lot about satellites, make a satellite, name it AO-40, and when it gets up it doesn't work, but thats beside the point) There are enough people around who have some understanding of the radio side of things.
Now as for someone radio-DOSing you I don't want to say more than I know but I do know of an important property of FM called like selection effect or something. In certain (or most, like I said I don't want to speak beyond my knowledge) cases a significantly stronger signal is selected over a weaker one and the weaker one isn't heard (I should remember more details but I'm a little sleep deprived today).
The question is how are you modulating this? The selection effect might not be as present in AFSK I DON'T KNOW. Are you doing some pulse-mod thing, FSK, or whatever (I assume this is digital, not like DTMF thing where you can just tape the tones and replay them, can you say air raid siren control)? That should influence the DOS possibilities. Anyway there will always be the noise issue, I guess I'm talking more about the DOSer overpowering you.
As for obscurity, people will still try to get in. Obscurity just makes it more of a challenge. By the way I'm not a cracker.
Now...
These jammers will ultimately become available to unqualified persons (probably the same ones who don't know they need to cut coax to an appropriate length or they'll have reactance, and bad impedence mismatches), these people will set up the crapiest jamming systems you've ever seen and they'll end up interfereing with a lot more than cell phones...
Maybe we should set power density or other field strength limits for this too. No more than x1 mw/cm^2 off your property and x2 mw/cm^2 on your property, these regulations on top of the rf exposure limits.
Aside from that I would love to see it in the US too!!!!!
Unresponsible jammers, please read:
If you interfere with me I give you notice, you don't stop I contact FCC enforcement...
One way communications may be acceptable if intended for the amateur community. Simply relaying this to yourself and other amateurs would almost be close to acceptable. Just don't be broadcasting to the public, and make sure no one is making money from your transmissions, unless it is another amateur in a one-time (read "not regularly occurring") exchange of radio equipment.
You may want to give Riley Hollingsworth (please excuse me if I spelled his name wrong) or another FCC attorney a call, or maybe the ARRL can help you too. Do call one of them to discuss the legalities.
I would suggest ATV, as was explained in the previous message. THERE IS A SMALL HAND-HELD ALL IN ONE ATV RADIO mfged by Kenwood I believe, you may want to check it out.
Now if I remember everything from my studies (I am a fast code extra if you couldn't tell by my call) this is all reasonably accurate. Again, contact someone else for the fine lines.
You know this doesn't have to be img tags. The same thing can be achieved through server-parsed html. Cookies don't even have to be used if every link has an id string in it. This term "web bug" doesn't mean much. The problem here is tracking by whatever means are used.
You can use Perl. Just write a simple cgi script to take the address you want out of the uri and send it to lwp then take the return and write it to stdout, when you're bored, add support for post and other http modes. This worked to get around my schools censoring stuff, maybe it will work for you too. If not, sorry.

I don't think I'd spend the time doing it though.

Just some thoughts...
They'll never take it down
But if they do it can die with Caesar as far as I'm concerned.
