I have SatPC32 working with the Yaesu G-5500 and FT-847, and just about everything seems to be working. (great)
Working the FM satellites are pretty easy, however, I am having a tough time with the SSB satellites.
My issue is with the frequency tracking on the FT-847. The frequencies change (on the 847), however, the changing of the frequencies doesn't seem to keep up the satellite. I get the satellite dialed it and sounding good and within a few seconds the signal is way off frequency and I cannot understand the station.
So far I have been having better luck tuning the radio manually, though I would like to use the computer CAT tuning.
Has anyone did a YouTube video on how to set up SatPC32 and how to correct this issue?
Thank you

Hi Brian. You may already do this but: Is your computer clock right on? I have a simple program running that goes out often and checks my computer clock against a time standard and resets the computer clock to the correct time. Another important items is are you using relatively recent Keplerian elements? With some birds, week old keps can make a difference. I am a member of AMSAT and appreciate everything they do for us. However, sometimes the Keps on AMSAT are a week old. I download them from CelesTrack with Space Trak TLE Retriever, they may be hours old. Finally with the low, high drag orbit of the ISS you can be off by minutes when they boost it’s orbit once in awhile. 73, Rick WB3CSY
