Can someone briefly explain how this works and if it is possible to
build homebrew equipment to recieve these signals........ what
frequencies its on, does it need some sort of signal decoder......

thanks

Okay, I see you're likely a DirecTV thief, but let me tell you what I know.

It's an S-Band downlink to the receiver. Each receiver has a unique ID Tag
that needs to be registered with XM before you can receive anything. I
suppose you could build an S-Band receiver and listen to the preview
channel.

Attempts at hacking the XM network have largely been unsuccessful.

Not only do you need the ID Tag, but you need the software to decode the
transmission. It's a variation of MP3, can't remember what it's called. It's
hard wired into the XM Receiver.

So far no one has "Cracked" the XM system. They HAVE successfully "cloned"
receivers by copying the RCVR's ID to another like unit.
I personally own 3 of them...for $9.95 for the first one and $6.95 a month
for the other 2...just pay the freight, it's a good deal for less than you
would pay for a month's consumption of cigarettes or coffee at
Starbucks....Eddie
