    "content": "Hi Michael, if your scanner is pretty deaf you could use a CJU antenna. It's \na small handheld antenna that hears the birds quite well (like a 7 elements \nUHF yagi) and, best of all, it's a simple homebrewed work. You will need \nnothing but a piece of plastic boom, a pair of rods and a short coaxial run \nwith a BNC plug.\nYou can see the CJU in action in this video \nhttp://rcfo.batcave.net/fo29movil.html and here \nhttp://eb4dka.batcave.net/ea4cyq1.html\nIn the first one I'm working the FO-29 using a Kenwood TH-F7E HT as UHF SSB \nreceiver and in the second one Juan Antonio EA4CYQ is using a Kenwood TH-D7 \nas receiver on the FM birds.\nThe schematics and building instructions for this antenna can be found here \nhttp://miguel.servihosting.com/eb4dka/ea4cyq/cju.pdf It is in Spanish \nlanguaje, but if you want I could email you (or anybody interested) the \nEnglish version (I´m working to translate my website to English).\n\nBest 73 to all,\n\nPedro EB4DKA\nwww.eb4dka.tk\nhttp://eb4dka.laserenadigital.com\n\n\n\n----- Original Message ----- \nFrom: \"Michael Tondee\" <[email protected]>\nCc: <[email protected]>\nSent: Thursday, May 31, 2007 9:41 PM\nSubject: [amsat-bb] Re: Using a scanner to hear the FM sats?\n\n\n> Thanks to everyone who replied to my question.
