Did you know that you can take a telescope and LOOK AT THE LANDING SITES ON THE MOON?
If you can afford the simple equipment necessary, you can literally send and receive a ping to a device left at one of the landing sites that proves without a doubt we have been there.
I'm not a radio engineer, but my understanding is you're just bouncing signals off the moon itself, there isn't a device that echos the signal back or anything. There are mirrors on the moon to reflect lasers back though.
They left a couple retro reflectors on the moon during the moon landings so we can bounce lasers off them to accurately measure the distance to the moon.
