AMSAT-BB,
I usually don't comment on the list but this is the third or fourth email string in the last month that brought up the HEO vs. LEO argument. I am relatively new to AMSAT but even then, have been working hard to learn its history, getting to know who is involved, and started volunteering to help the organization build the FOX series of satellites. I'm excited to be a part of it. Before people keep going on arguing that AMSAT is or is not developing the right technology to suit their needs or to even launch a satellite into orbit. I urge you to find out what AMSAT is currently working towards.
I have linked to an interview with Barry Baines, WD4ASW, on the HamRadioNow youtube channel. The link below links directly to minute 18:00 of the interview. To everyone not currently up-to-date with why AMSAT is developing portions of the FOX project please watch from minute 18:00 to minute 23:00.

I hope to keep learning about AMSAT, keep volunteering my time and resources, and to keep promoting amateur radio. As a college engineering student (senior) and as someone who has worked in the aerospace industry (R&D of launch vehicles and satellites) I can understand why the colleges need to educate future engineers, why launch opportunities cost so much, and why AMSAT is on the direction it is currently heading. Again, I'm not an expert in these areas and I have much to learn, but I have the background to at least understand some of the reasoning behind these topics. I look at many of the satellites that people talk about on this list, wishing they were still working, and realizing many of them were in operation before I was even born. Maybe we will see similar satellites in orbit one day, I sure hope so. Launch costs need to come down. Thank you for your time, I look forward to meeting all on the air one day!
Sincerely,
Bryce Salmi KB1LQC

Hello,
Newer technology and more advanced modes can be made available for experiment, either simultaneously, on (say) bands L, S, C, etc, and also on more accessible bands (U, V) by having the bird switch mode accordingly ... As far as meshed networks ...
Like these designs?
Proposed in 2003 - http://www.cnssys.com/files/amsat/cc_amsat.pdf Proposed in 2004 - http://www.cnssys.com/files/amsat/cc-revisited.pdf Proposed in 2006 - http://www.cnssys.com/files/amsat/SDX_and_Future_AMSAT_Missions.pdf
Thing is ... everyone knows we've been looking for a suitable launch since the dates of these papers. Other cool designs live in the Symposium Proceedings for AMSAT-Eagle and the Phase IV GEO-Rideshare projects.
Some of the good old days are archived in the "Historical AMSAT-NA Symposium Proceedings" - http://www.klofas.com/amsat_symposium/
