Data from Port side and South was better received than from overhead or closer

Two passes of London one at 12.45.30 at 135 miles from surface receiver and the other at 14.21 and at 535 miles from surface receiver found the window for data receipt on the first was from 12.45.40 to 12.46.37 say one minute. The second was from 14.19 to 14.23. This demonstrated that the closeness to the receiving station does not always have longer communications window period. It also confirmed that receipt from the South and from the Port (Left) side of the ISS was better than from overhead.

This is very interesting.

This is very interesting. Others have observed that reception can vary based on geometry. I once received a school contact better than the telebridge station that was closer to it. Thanks for sharing.
