Bsaed on recommendations here and a few other places around the net, I use Ham Radio Deluxe (HRD). While HRD has WAY more bells and whistles than I need right now, it is impossible to beat the integration and list of features for the price (free). With the latest version, the log book and satellite portions of the program are separate programs, so I normally only open 1 or the other.
In the satellite program, the radar scope is easy to use during a pass and the "Tuning Bar" allows me to quickly glance to check doppler shift on the UHF side. The easy integration with eQSL and LotW are big selling points for the logbook program to me.
I am also trying out "Satellite Tracker" on my iPhone. The free version seems to have all you need. Big benefits of this app:
- it keeps an updated page of "next passes" for all of your selected birds with a countdown timer. I rcvd APRS beacons from ISS last night because the little program alerted me to a pass that I had missed in HRD. GREAT pass by the way... ISS was extremely bright at the beginning of the pass (thought it was an aircraft). ISS AND PCSat (I beleive) were both visible and appeared to be flying in formation.
- it has an elevation ring that changes based on the elevation of the iPhone. Doing my pre-pass practice arcs is very easy once I have my AOS/LOS bearings.
