Hi Red, A couple of things come to mind. Foremost, try using VO-52 to get your station up and running instead of AO-07. There have been a couple of posts recently that indicate AO-07 is getting a bit intermittent and hard to get into (esp. SSB). I do VO-52 passes most evenings and it's working well, so it will take one variable out of your equation.
As for the SatPC32 setup, I have some screenshots on my webpage that show the settings I'm using. I use 2 x FT-817, but the setup should be similar to FT-817 + FT-897 systems. http://kb5wia.blogspot.com/2010/10/satellite-portable-station.html One thing I'll also do is to quickly spin the tuning dial as I transmit, just in case the PC control isn't working properly. If you don't hear any downlilnk when spinning the dial up or down a few kHz, then you're likely not making it into the sat and something else needs to be checked. Hope this helps! 73 de Dave KB5WIA On Mon, Jul 30, 2012 at 5:50 AM, W M Willoughby <red...@bellsouth.net> wrote: > I have made a few QSOs on the SSB birds while running half-duplex.
