Here is a list I had of the sats from 61.5-139 on both C & KU. You would need Channelmaster to load it
I think on the 3500 you need to use a RS232 cable so once that is hooked up
unzip file
open Channelmaster
open file
select "write to STB"
select Pansat 3500
it will write the list to the receiver but I do not guarantee anything (I can guarantee that lots of folks have used this list with no issues)
