I love the ease of the user interface on the ISS fan club tracking program however I've noticed substantial differences between the pass predictions from it compared to other prediction s/w. Last night the prediction was about 4 minutes earlier than the ISS. I also sometimes find the attitude & azmiuth to be significantly different as well. Is there anything a user needs to do to correct for this for their local area? The location I am using is less than 1 mile from my station, so it should be relatively accurate.
Thank you in advance.

I´m very happy today. I used a homebrew arrow antenna for receiving a powerfull packet radio signal from ISS. Stations displayed in UISS: EA5AEL and CT2ECS. From Madrid, Spain. 18:44 UTC

Next time I wish to hear to Bill or Valery in 145.800 Mhz.
