Interested in knowing what satellite element files others are using and which ones they use most. I currently download the NASA files from CelesTrak, the tle.zip file from Don Gardner, the dklist file from SatEvo and the grouptle.zip file from OIG. Do many of you use the BIG one Alldat.zip file from Mike McCants? 8000+ satellites seems like an awful lot of satellites to keep track of especially for visual purposes. I have the disk space but whether to use it in combination with the other files is my big question. Getting too many files in the database at one time could prove to be a pain. Any response would be greatly appreciated. Thanks ahead of time to all those that respond. Jack jackwx@aol.com 40 51N 81 56W
