Yes, we noticed that 2/3rds of all PCSAT-1 users are in Europe
in a SMALL footprint.  While in the USA, there are only half as
many users but spread out over a much larger area.  SO the
congestion must be maybe 4 times worse over there in Europe..

Yes, any collision will cause the weaker signal to not be heard.
And then the stations just keep trying, further making the
problem worse.

We need to find a way to cut back the throughput in Europe,
because it is always over Europe that PCSAT-1 dies towards the
end of its daylight period.    We have asked all PCSAT-1 users
to adhere to the User Service Agreement that was posted:


Which is posted on the PCSAT web page:
