I've used the Stab positioner with several different Pansat receivers in 'USALS' positioning mode and never had a problem. Set my Lat / Lon and it hits every satellite dead on. I seem to be missing something with the Pansat TC-1000 however. For some reason it just isn't landing on the satellite, or I should say it isn't landing on the correct satellite. I've done a factory reset on the TC-1000. I've reset the Stab HH 120, but still no joy. I can connect my 9200 or 3500 and it works perfectly. I must be missing something. Any ideas?
