Interference From Home Satellite System's

[radiolalaland]

Is it possible to recieve interference from Satellite's?

My base set up I use a base antenna attached to RG6 cable that is coming into the house to my radio.

The antenna is about maybe 6-8 ft. away from the satellite dish. Which I believe also uses the same type of coax cable.

Now I'm in a multiple unit dwelling with one other unit that is probably sharing a split off of the dish on the roof but two seperate acct's. I know lot's of building's around town that are doin the same thing. Is it possible that they might have an illegal setup (meaning a hack card), that would interfere with my VHF Signal's that i'm getting more an more interference off of. Or would it be that I'm getting interference through my own system.

I myself don't own one of those illegal cards, but I thought I'd just ask. I am noticing the cross interference though when I'm watching a channel on tv, but I hear some faint but obnoxious signal's interfering on the radio.

Both lines for the scanner an the satellite run almost parallel into the house, an both use the same type of coax.

How can I fix this problem? Mind you, this has only started happening with in the last couple of months, after I had put up the base antenna.

Look for a strong birdie on 121.5000Mhz and/or 243.000Mhz. That's usually the sign that someone has put something into the smart card slot which brings all sorts of signals outside of the box.

Not much you can do about it unless you can find out who they are and report them to IC.

wITHOUT QUESTION (some) HACKED CARDS ARE KNOWN to be a source of interference to other electronic devices, a few things you can try...
see where the coax goes off the dish (you say its split) see if you can have a coversation with your neighbour to see if he is doing the hack,
try quad shield RG6 if that is all you can use for coax, (not my first choice)
also the fact that it is parallel should not matter much but seeing as wires in parallel in generally can interfere with each other, if you can eliminate that it might help, especially if the hack is going on.
Also in my setup I run an isolated power bar that regulates incoming ac and attempts to mute RF on the line, make a big differnce for me,
BTW my sat box is on the opposite wall to my shack (no problemo)

Yeah, it's hard to say where exactly it's coming from. There's many dishes around the area.

Not much I can do about it really, and no, I don't know which unit it is that's hooked up to my dish too.

You mention power bar's an such. How does this affect the way one would listen to scanning signal's with out intermod signal's?

Holy cow !

Creating interference on the VHF and UHF Aviation Emergency freq's
is really looking for trouble !

I still get birdies as they are internal to the scanner, thankfully they are not on any programmed frequencies I listen to, and still can get intermod, it is more or less the fact that the radios now get clean power supply , no surges and for the noise floor of the overall sound is cleaner, you gotta experiment to hear the difference.

Yep. My parents got a visit from an IC inspector a couple of years ago after he chased down a 121.5 birdie to their house. They have LEGIT satellite so it wasn't that. Turned out to be the "flying saucer" antenna they use for OTA broadcasts.

The signal is being radiated from the hack card which projects out the front of the satellite receiver. 121.5000 and 243.000 are internally generated in the receiver but the shielding provided by the case keeps them from leaking out. Once these signals are brought outside of the box by inserting an emulator or avr card, they radiate. It's made worse if a cable is attached between the hack card and a computer. They only way to contain these signals is to place your emulator or avr inside the box.

Changing to quad shield coax or putting rf chokes on the ac line will not do anything to this signal. It will stop other signals from radiating via these cables.

This has caused a big problem. Industry Canada's website had a press release on the subject not too long ago. It's probably still there if you search hard enough.
