Thanks for the reply. The puzzle is I update keps almost every day. I changed over to nasabare after the failure this morning, so we’ll see what happens next.

It sure sounds like your keps are out of date.  A couple thoughts:

nasabare.txt is updated more frequently than nasa.all--several times a week vs ~weekly.  The ISS especially needs frequent updates since it can maneuver.  

Another thought:  How recently did you update your elements?  SatPC32 does not update them automatically (unless I've missed something--I use MacDoppler more frequently).

My SatPC32 Doppler control is way off and I can’t figure out why. Seems to affect only the ISS. As it approaches, the incoming signal is almost 10kHz high — about where it would be with no Doppler adjustment at all. My Doppler.sqf line reads
ISS,437800,145990,FM,FM,NOR,0,0,Cross band repeater
and keps are current from nasa.all. I also notice that SatPC32 is off on predicting LOS. I was still copying signals 59 well after LOS had supposedly occurred.????????
