Hi leo:
Leave the dish alone -- don't realign it. What Michael is telling you is to check the satellite parameters in your receiver to those on
www.lyngsat.com ; you must verify 3 things on each transponder -- frequency, polarity and symbol rate. The actual transponder number (like TP17, for example) is, like Michael says, irrelevant. It doesn't matter what transponder number the receiver says it is -- as long as the parameters mentioned above are correct you will pull in channels.
