the reality of a lunar transponder (or even a packet system) would be that it would encourage a lot of things that the FM sats do not...and discourage a lot of bad things...it wont happen I know because of a lot of reasons...but it would change our hobby and the satellite part of it for the better.

Bob...its been done here a zillion times...it wont be done with an HT and a small yagi...it will however be possible whereas a "Mars" effort is really not possible for anyone except "Goldstone class" stations (and the time delay makes it well a unique form of transportation).  A small linear transponder with some horizon omni gain antennas would be a challenge, but it would be easier then moonbounce Robert G. Oler WB5MZO life member AMSAT ARRL NARS

Just for the sake of conversation and thinking.  What would the link budget look like for a transponder on the moon.

to bad there cant be an amateur radio payload even a really small one...this probe should be "longer lived" then most as it should have a constant energy source...

Wonder why the Europeans are thinking of sending Phase 5A to Mars?  It will probably never fly and almost no hams can be a part of that...so well why not send it to L2 in the Earth Moon systems...a halo orbit...
