Hi Kent, Apologies as it might seem as if I am pointing out something which you have checked out. Apart from the clock setting which has been mentioned two other main factors are common things that I have found users to have wrong. The kep set being accessed by the programme is not reading from the correct source in your set up. The location of the user has not been set identical for each programme and in some cases has even been the default setting! You will find slight very minor differences between software but not to the extent that you appear to be getting results for. To find out which programme is correct for your location try using the Amsat web page which will give you either live tracking or predictions for any amateur satellite. Again make sure that you do put in your correct location ( either LAT /LONG or grid square and convert this) Good Luck I am sure that it is something very obvious. Ken Eaton GW1FKY Amsat -Uk Amsat NA
