    Dish sat receiver vs. XM receiver

    I have a question...it may seem stupid, but I can't seem to locate the information. What is the difference between the XM receiver and a sat dish receiver? I know that you have to point your sat tv receiver to the south for it to work...but XM radio and the like works no matter which way it's pointing...Why am I asking? I was wondering if there was a way to hack an XM receiver to receive tv signals....
    It's probably not possible...but I just thought I'd ask anyway...

    Thanks!

    That I don't know, but I think it would be cool to install a satellite (DirectTV?) on the roof of your car, but but it on some sort of rotating base which is tied into your GPS system. That way, no matter where you go, it can be programmed to always face south. Cooool...

    Yeah - plus if it would be possible to use the XM antenna, it's really small - like the size of a roll of quarters.

    I've seen them for boats, but their big (size of a basket ball) and expensive (>$2000)

    Well technically the technology is all similar.

    A radio wave somewhere in the Gigahertz bandwidth transmits digital data down to earth from the satellite.

    GPS uses a very small bandwidth.

    XM must use more bandwidth (music contains more data than the codes sent from GPS)

    Dish Network uses the most bandwidth...video and HiFi stereo audio ...something slightly less than a DVD bandwidth, maybe 3000Mbps at most. (no flames)

    So that is why the Dish needs a 'dish' and the xm/GPS do not.

    Therefore you will need a dish to receive the TV signal.

    Luckily for you there is an aftermarket solution...search the RV or SemiTruck accessories catalogs, and you will find a mobile antenna that automatically tracks the satellite...for about $1000 on up.

    Most importantly, are there XM hacks out there? There are lots of people running DSS hacked... Not that any of us would do such an illegal thing, but it certainly is an interesting question considering we have computers in our cars that could decode the signals.

    Well, that information (thanks DodgeCummins) lead me to thinking - if it's just a bandwidth issue, can you use multiple antennas to receive different parts of the signal and send them to to decoder where it can be pieced back together? Or should I just take another hit off the crack pipe?

    Yes but as they won't be in exactly the same location there will be phase differences between the signals recived, and sorting it out will be a head case and a half.

    Total re-design underway: on the whole progress is very slow as the car is taking up too much time :)

    Maybe if there was a way to filter certain parts of the feed to parse it and have it reassembled in the process, with the only drawback being a delay in replay of the programming, which wouldn't matter a whole bunch. I wouldn't know where to begin writing a program to piece the puzzle back together as my programming skills don't reach quite that far....
