Recently erected my own kit and now I'm getting to grips with the hardest part - discovering what my kit is capable of.

To this effect I've discovered a whole new tech language that details how to locate a satellite channel. Can anyone fill in the blanks for me and other newbies? Here's an example

I understand from this that a new channel 'Russian Travel Guide' can be seen via the Hotbird sat located at 13 degrees East. Clear = Free to view. The frequency is 11013MHz, Horizontal polarity. But what's the SR, FEC, SID and PID?

Specifically with reference for my TM machine - where the users manual describes the Video PID, Audio PID and the PCR PID. I understand these are specific control details, but for what? E.g. Which of these should contain the 'PID' details described in the quote above? Also, is that PID 369/625 for English and PID:369/881 for Russian or something else entirely?

And I haven't started on cams yet! Which looks to me like a minefield with active target-seeking mines!!

SR = Symbol rate (commonly 27500)

FEC = Forward Error Correction How much of the frequency is used for error redundancy. A FEC of 1/2 uses half the signal as error checking and will be a robust signal although low quality (half the data stream is redundant info) A FEC of 7/8 will be a high quality signal but not robust as only 1/8th of the signal is used for error redundancy.

SID = Signal Identification (unique to one data stream on any one frequency)

PID = Program identification. The first number is the video stream, the second one the audio

Thats correct The video stream is obviously the same, audio 625 gives you English, 881 Russian. (Note - most receivers just allow you to change between audio soundtracks just by selecting a soundtrack - you dont need to worry about the actual numbers in 99.99% of cases.
