MacDoppler

Simply said....two steps forward, one step back. There appears to be a shift in Celestrak reporting names/format, and while the 2.0.7 release should be compatible, they're not there yet. If you use this, use the AMSAT keps, but be prepared, AMSAT does not keep a list as comprehensive as CelesTrak, and it only updates once per week, which is not suitable for tracking the ISS. Also, apparently, they are now referring to the ISS as "ZARYA" instead of "ISS" or "ARISS". MacDoppler really needs to have an "Append" or "Add To" function for the satellite keps list. This business of just pulling the pre-packaged sets from CelesTrak is just not robust enough. Without such a function, it leaves the user having to manually pull all of your desired keps, assemble them into a text document, and then finally importing the complete list into MacDoppler. Partial lists cannot be used as it will delete any sats not in your upload list.

I just started using satellites in the past 2 weeks, and I'm dedicated to Mac. This package is an absolute must have if you're interested in this communications mode. I use it with an ICOM-910H, and after an initial doppler recalibration, it does all of the troublesome tuning and tracking automatically. It completely eliminates all of the hassles that have kept me from trying satellite modes all of these years.
