Let your Ariza 700 do a power scan on each satellite, then modify your active channel list using EDIT & SKIP, do not try to delete channels right on the receiver. If you try to delete channels, you might have problems, like I do, because of glitches in the BINs. Once all satellites have been edited, then you can transfer data to your computer with a null-modem cable. I use G-tools & it works fine. You can save your files, then delete channels you have skipped, if you want to. You can also do Alphabetic channel sorting right on the receiver, or in G-tools.
