So with the help of amishone, we found the RFI I was hearing on the 440 band last week.
It wasn't comcast, surprisingly. But it was deceptive. Apparently it was an IF product of a far more interesting frequency that turns out to be a studio loop for TV 7 (WXYZ).
Yea, it's patched straight to their intercoms. And yes, it's funny. :-)

wiat, you're picking up inhouse bleed through from a tv station?

Now if you can reason out how to overthrow that signal to have ham conversations broadcast over the news...

It's not exactly in the ham band, you see. But we presume there's another signal, one registered for mobile use that goes back into their headsets. Start saying shit like "(name of news anchor), wipe your nose You've got a boogie"
and then watch them react on live TV. Or just start sending barking dogs or something fucked up like that. See if you can cause the news anchors to lose composure.

listen to it a while to learn how to do a maunal/audio feed (make them your parrot).

Well, the funny part is it's really hard to talk and listen at the same time. You instinctively stop talking when someone else is saying something because you're trained to be polite. (This is why some TV anchors seem rude in person, because they've trained themselves to talk even when they hear other voices, because usually they are the only ones that hear the voices) It took me quite a bit of training to talk while the intercoms were going when I was working at the TV station. I wonder if their anchors are trained well enough.

doesn't that fall under the Ham rule of "can't cause inteference to others"? Being that they're technically not on Ham bands (only spilling onto the ham bands), is that rule now null and void?

shh. We can cause interference* in our own band. But not other people's bands, since we legally can't transmit there.

Not that I intend to, but I'd like to point out that if one did this only once, quickly, they'd never figure out who did it.

* We can cause interference to part 15 users in bands where we are primary or co-primary with part 15 users. Technically we can't cause intentional interference to them, but they are required to accept it either way.

yeah, like any of us could do just once, quickly :-P And just what is up that part 15 crap? I have to accept interference? I can't install filters or whatnot?
Oct. 25th, 2003 10:07 am (UTC)
You can filter all you want. But if we transmit over top of you in 900Mhz or 2.4Ghz, it's your problem, not ours.
Oct. 25th, 2003 10:56 am (UTC)
Ok, so I'm just misunderstanding the rule then...saying that I have to accept it is meaning that its my problem to deal with, not the transmitter.
Oct. 25th, 2003 10:59 am (UTC)
Exactly, And if you are unable to deal with it, too bad. That's the idea.

Think of it as the legal way of saying. "We're giving you free bandwidth. You're sharing it. You can play with the others or you can take your ball and go home, but dont come crying to us."

dammit, now if only they put that on the stickers instead of the legalese, we'd all be better off :-P
Oct. 26th, 2003 01:26 am (UTC)
Well, they'd have to add the part where you can't interfere with others. As a part 15 device you're not permitted to interfere either.
