With the amount of libration on the moon, what's the maximum antenna gain per band that you can get before it becomes too much of an issue.

Perhaps this should be in the Amsat FAQ =%-)

Perhaps with all the "noise" (pun intended) here recently about unlicensed transmitters on 2.4 GHz... the following line from the article:
"For a given TX e.i.r.p., signal strength received at Earth depends only on the mechanical size of the RX antenna; frequency is irrelevant [1]. Noise level however is not, and S-band (2.4 GHz) is a sensible downlink choice because very low noise performance is robustly obtainable "off the shelf"."
Is more controversial than it once was? :-)
Or maybe not. Depends on who's arguments one liked during the recent 2.4 GHz debate on the mailing list.
The above comments notwithstanding, nice article James. Thanks for sharing the link. I learned something from reading it, and that's always a Good Thing.
