[amsat-bb] HEO opertunity

Agreed, but thinking back to AO-51, weren't there some geographic
limitations to the use of 23cm as an uplink?  Have things changed since
then?

I'd love to get some use from my 23cm setup on the birds again, and the
AO-40 downlink is sitting in the attic, totally unused.

My detachments did it all the time, easy peasy.  Granted that military radios are pretty much point and shoot, and easy use for relatively untrained soldiers.  Ham gear for 23cm is common in Europe, and there is no reason we in the USA can't have that capability.  I have a 23cm module for my FT-736R and a home brew helical with which I rag chew with the other hams on 23 in the middle Tennessee area.  I am not suggesting we all mold and cast our own wave-guides, but just put some effort into the old Ham Radio "home brew" thing.  One thing about S and L and the other microwave bands is that we have bandwidth out the wazoo.
