    This antenna array is used for EME. For those not familiar with that acronym, it means using the moon as a radio reflector to send signals back to earth: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Earth%E2%80%93Moon%E2%80%93Earth_communication" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Earth%E2%80%93Moon%E2%80%93Ear...</a>

    I love reading about the exploits of radio amateurs. This is some seriously impressive engineering too. It&#x27;s surprising what one can do with off the shelf components assembled on a human scale (instead of microwave frequencies which need much smaller circuits).<p>Also, there&#x27;s a certain beauty in staying close to the physical layer and working the airwaves yourself.

    The caption for the WAS aware clearly mention 52 US states.<p>Is that a typo or some quirk of radio amateur?

      I believe that&#x27;s a mistake. The page of the award mentions only 50 states: <a href="https:&#x2F;&#x2F;www.arrl.org&#x2F;was" rel="nofollow">https:&#x2F;&#x2F;www.arrl.org&#x2F;was</a>

      It seems to be a typo, unless the criteria for the award have changed: <a href="https:&#x2F;&#x2F;www.arrl.org&#x2F;was" rel="nofollow">https:&#x2F;&#x2F;www.arrl.org&#x2F;was</a>

      Or perhaps incredibly prescient!

    Just 10W of RF to hear your own voice relayed by the moon is insane
