These are identical to the actual flight hardware, used for testing and measurements. They now reside at the W2DU Florida QTH, and while the batteries have long since expired, if the solar cells are illuminated by a 100 watt bulb, or the actual sun, you can receive the transmitted beacon signal at 108 MHz. Low Tech by today&#8217;s standards, but in those days it was hard to find transistors that would work above audio frequencies.<\/span> <span style=\"font-style: italic;\">Photo 21 shows a complete beacon system. To the bottom left is another transmitter, before potting. To the bottom right is another transmitter, potted and ready to be incorporated in the styrofoam &#8220;dish&#8221; assembly.<\/span> <span style=\"font-style: italic;\">Photo 22 is a close-up of the two transmitters from photo 21.<\/span> <span style=\"font-style: italic;\">Photo 23 shows an entire dish assembly, prior to potting in styrofoam.<\/span> <span style=\"font-style: italic;\">This space project, and many other early space projects from the Astro Electronics Products division of RCA will be chronicled in the soon-to-be-published Reflections III by W2DU.<\/span><\/p>\n<p><a onblur=\"try {parent.deselectBloggerImageGracefully();} catch(e) {}\" href=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEh_bxMjGsX2Kn8Sg97u3mNaZu1rNidbjoiECx5Oq1LAW_5KIuYDgIYskQHXExJXSjKBE8zflnemUMaIcEeOFw-chh0m46hLos92daoFQpH1x6loIWYHzeUg1e53Jf7qzVJ5w2JmHVgY2bU\/s1600-h\/Photo+23.jpg\"><img decoding=\"async\" style=\"margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 400px; height: 335px;\" src=\"https:\/\/www.homebrewradio.us\/blog\/wp-content\/uploads\/2008\/12\/Photo23.jpg\" alt=\"\" id=\"BLOGGER_PHOTO_ID_5283601969372336658\" border=\"0\" \/><\/a><br \/><a onblur=\"try {parent.deselectBloggerImageGracefully();} catch(e) {}\" href=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEi056fB0vwljioIpc-OdM16l_yV6FHrE1_1IqqnCdXucdwsFZ-9Z-NaAX6D3oaGaiifsSKECAwFtoxv4x4PQgpFRP-fOPz7oNwntQN4n0CPHkLS5IBvVTAUXEHeTiCIMt5vKVOyQqd0qII\/s1600-h\/Photo+22.jpg\"><img decoding=\"async\" style=\"margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 270px; height: 400px;\" src=\"https:\/\/www.homebrewradio.us\/blog\/wp-content\/uploads\/2008\/12\/Photo22.jpg\" alt=\"\" id=\"BLOGGER_PHOTO_ID_5283601758668769650\" border=\"0\" \/><\/a><\/p>\n<div style=\"text-align: center;\"><span style=\"color: rgb(255, 0, 0);font-size:180%;\" ><span style=\"font-weight: bold;\">MERRY CHRISTMAS FROM ROME!<\/span><\/span><\/div>\n","protected":false},"excerpt":{"rendered":"<p>W8KHK gave a very nice Christmas present to the AMfone group.
