I was merrily rolling along with a full-dir then all of a sudden WISP loses all it's config data. Sats disappeared, my lat long is set to 0, etc. There doesn't seem to be a corrupt file involved. I try to redo a sat and it doesn't seem to accept any data, just the sat name. Is there anyway around this other then a complete re-install? I'm running WIN10... 73 Jeff kb2m
