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!)
