I would have to think that when the satellite does re-enter the atmosphere it will be in the southern hemisphere because it's Parigi is down there.

But that image that was posted recently looked like the perigee really hasn't changed a LOT the orbit has become much more circular.

Correct. The drag at perigee reduces the total kinetic energy of the satellite, so when it continues it's orbit, it won't reach as high of an apogee. The initial perigee was around 212 km, but the initial apogee was over 500 km.

For anyone planning to try the next two USA passes, please note that it was WAY ahead of the current TLE's.
I had to go to manual rotor control; fortunately on the SDR display I could just slide the RX frequency over and the tracking was in the ballpark from there.
