[amsat-bb] HO-68 orbit comments.

[John Hackett]

Hello Dom,
                You are of course right.

I have been in contact with Alan Kung regarding various aspects of HO-68 but as you correctly state, 
The Chinese don't seen to want to share the workload.

I went as far as offering donations to help Amsat China  but was politely refused (!) ... the implication being that subscriptions would require reciprocating with 'information' - (which was NOT my intention).

I think your comments will give people a better understanding of why the orbits are not always otimum
for certain times/areas.
