0404 EDT pass i was alone signal good S4 S5 start to copy at 12 deg
0612 EDT pass start to copy at 8deg copy was peaking at 20 db over my noise floor signal only interrupted by blocking object. It was a 65 
deg elevation pass here. Made QSO with N8BBQ Edward and N8MH Mark

Near the end of the pass a rapid pulsating tone carrier appears it was just at the same level as other signal at times.

As per my test S band signal is lower at this attitude on low pass to a point to be weak to be received. Depending where the satellite is 
also made a big change in the signal strength when he pass my latitude on one occasion the signal increased by 1 s unit
