The receiver audio is sent to a ACER PC (Vista Windows) line input. The audio is encoded running Edcast using AAC at 16Kb.

The radar&#8217;s primary mission is to track satellites and space debris for the US Space Command. It can detect objects as small as 10 cm orbiting 15,000 km above the earth&#8217;s surface. <\/span> <span style=\"font-family: Arial,Helvetica,sans-serif; font-size: small;\"><a href=\"http:\/\/www.spaceweatherradio.com\/index.php\" target=\"_blank\" rel=\"noopener\">Source<\/a> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>LISTEN SPACEWEATHER RADIO (Live) Live Radar Audio Feed&#8211;how do we do it?
