The HF Active Auroral Research Program (HAARP) (a Google Video) radio signals are clearly heard in the 40 meter band, echoing off the Moon. This video shows S-meter readings as seen on a Yaesu FT-1000MP amateur radio (ham radio) transceiver located in San Jose, California. And of course a thorough explanation of what you are watching/hearing can be found on About the HAARP - LWA Moon Bounce Experiment.
