Well I will have to give it a go in a 301.010.

What are the size differences between the 2?

sorry psy I got them mixed up, there are 2 versions of the 013, 1 with a single tsop (32Mb) and the 2 tsop model (2x16Mb) so if you have the single tsop then it's looking for a bigger chip, if you have a dual tsop model then it should e the right chip but the receiver needs a vidmod apparently. as well I would imagine that if you threw that chip in a dual 013 then it would have to be in the second tsop area as the first tsop would be needed for boot, kinda wished I hadn't thrown out my 013's. but there has got to be someway to jtag or program that tsop through the sta240 or something cause it looks like that decoder chip is the main processor, then it would just be a matter of sorting out the data from the tsop. if I could only find the pinout of that sta240

k found an atmega32l on my sirius board, it had a pretty ornery sticker on it, but a little isopropyl and a qtip took care of that, now I know I can jtag an atmega32l but the question is whether or not this actually contains the sub info or something else.

well looks like interest has faded for this project, I may pick it up again later on but for now I guess it's dead.

Can you elaborate on how you determined this?

Hi, guys,
I found something interesting, maybe this will give you some boost

Read this first:
http://www.larrywolcott.com/projects/XM01/index.html

This method is really cloning ID.

Next, I have schematics for Sony XM01, the same receiver the guy is talking about.
There is a chip labelled CAP which takes care of encryption, part number ST19AF08, it's secure micro similar to CAM.
If there is interest, I can post schematics, also suggest in which folder.

The next step I guess is to get actual device and start logging communications.

I would choose the path of least resistance, to quote a previous post in this thread:

A friend has three in pieces on his bench, one active and two non but different models. One has a TSOP pulled but I don't think he needed to go to that extreme. Still waiting to find more clues.

I wish my EE skills were up to par for this challenge but I'm definitely going to research this more. Why does everyone keep quoting that larrywolcott website for info about XM. We're talking about Sirius not XM and that site flat out says he tried to clone the TSOP and it failed because the TSOP had nothing to do with it. Circuit City had a sale about a month ago on a car reciever for about 5 bucks so I picked one up and I'm cracking open the case right now to view the chips involved.
