I speak as a relative newcomer to the world of amateur satellites but
suffice to say, I am totally immersed in them now!
My thoughts are that whilst it would/will be nice to have an HEO, it is
imperative that we replace those easy sats that are coming to the end of
their lives or risk losing a whole new generation of amateurs who like
me will stand in the parking lot of a hamfest one Saturday morning while
Drew gives a demonstration and say to themselves, "Wow, that's cool"!
AO-27 is MIA, FO-29 was rescued thankfully. More recently we learn that
DO-64 will not be available....these are the birds that we should
concentrate on replacing!
Newcomers will spend a little extra to be able to work FM and SSB LEO's
but surely no-one is expecting people to spend a lot of dollars on
microwave stuff for a bird that might not a) make it to orbit or b) work
properly or at all.
I would be prepared to donate $1000 for a share in getting another FM or
SSB bird up as soon as possible and then once one, maybe two are up
there then worry about an HEO.
The way things are going it seems unlikely that an HEO is going to get
up in my lifetime and by then all the LEO's will have gone anyway. The
LEO's are our bread and butter so to speak, the HEO's are the caviar!
Just my two cents!

I have read the background of many of our members and BOD, we indeed have many very smart educated people in high places. Am I naive about the details? No doubt. I'm just a retired old ham with a back yard full of unuseable antennas, and a lack of comprehenson about what is going on (or not). If this diatribe is all wet I can take the slings and arrows. Talk to me about it on AO-7.
