      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.

I would like to see 23cm and above seriously considered.  My military experience (30 years) demonstrated to me how easily we can communicate with lots of bandwidth up there.  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.

Is there a reason why S band is not being considered. It was good on AO-40 (sobsob). Probably because of local QRM etc.

Nick, Zach et al,
The suggestion for an L band uplink, or any uplink or downlink above 70cm 
for that matter, is very welcome. We absolutely need to populate the higher 
UHF and SHF bands in a way that we can justify their allocation to the 
amateur radio and amateur satellite services when we amateurs sit with 
regulators to defend them. Higher bands are more challenging to use, but 
they do offer advantages -- wider bandwidths, higher data rates, etc.

AHHH, sorry, i screwed that one up.
Two birds with L-band up (1Cliff and 1D), but not the one with the linear 
(1E).
Somehow I can't get that straight in my head (this isn't the first time 
I've mixed that up).
So many Foxes of various band/mode combos on the way! I suppose in a way 
this is a good problem!
Sorry, Jerry (and everyone else). I hope I didn't cause too much 
confusion there. And thank you very much for the correction.

I would just like to correct this information, so that everyone is aware 
and not surprised by what will be in orbit. 
Fox-1Cliff and Fox-1D have the L/v band capability that Zach mentioned. 
RadFxSat-2 (Fox-1E) will not.
Thanks.
