With those nice dishes on the lunar rover and next to the lander? Those 
will produce a wonderful ERP if fed with any nontrivial power!

(since you seem to have highlighted what's apparently a transmitter, I 
assume you have no clue what I mean by the ERP and only care about the 
transmitter power. So, go back and reread the post where antenna gain is 
discussed)

(and you deleted the part about hams bouncing radio signals off the moon 
with a 1 kW transmitter [actual input power, not ERP]. I have seen that 
done _in person_. US law for amateur radio restricted transmitter power 
to 1kW input, meaning even less than that actual output power. But no US 
restriction on ERP! Just the laws of physics!)
