Paul,

Thank you for your reply - I think I have solved the problem

I use SatPC32 to control my rig and I have calibrated it to be fairly close for receiving my own transmission early in the pass.

HOWEVER - today, I had to tune 6.5Khz higher than I normally do to hear my own signal ! Once I found my own signal everything was back to normal

I know there are other people having the same issue, so I wonder what has happened to the satellite?

Thanks to everyone who has replied.

Peter
