I agree, he can tell us exactly what is different. I opened it up in my PRL editor and it shows three systems, SIRAB 6505, 5117, and 5035 using PCS block W. Not sure what block W is. AWS maybe?
Edit:
Upon further research I used a different editor to view the file and this one showed PCS blocks: Any. As a note, all the other cricKet systems have specific PCS channels listed and not channel blocks.
