Shankle, Lyngsat is often out of date and confusing. I'd use the "list " at the top of the page here. Also Global-cm.net is good as well. Check those list first and what I'm saying should make more sense. Example on Lyngsat would be HITN, use 3877 H 4444. The 104 your looking at was either the audio or video PID.
Example if you were to manually enter a channel with a tp of say 3876 H 5182...info from Global-cm.net,
the 5182 is the symbol rate. If you're blind scanning the VPID or APID wouldn't matter it usually finds it if you locked the transponder in ok. If you manually enter the info...example the receiver lets you add a channel manually....you'd enter 3876 H 5182 then APID 512, VPID 513, and PCR 512. The PCR usually is the same as the APID. Here's an oddball situation...If you were blind scanning say 91W Cband most receivers won't pick up the CW channels....that's one example of something you'd have to manually enter all the info including APID, VPID, and PCR. Several radio channels require you to manually enter the APID info as you can't blind scan them.Believe me if you look at one of the other lists if will make better sense than starting with Lyngsat. Hope this helps and wasn't more confusing If I missed something others will let us know.....Blind
