I have no idea what power actually reaches the antenna, but, between the cable and all the connectors, I expect it's only a couple of watts at the most. Trees definitely are a factor (can't shoot through them very well), and I am on an Az/El rotor system so I can aim at the satellite pretty well.\n\nAs Drew notes, Doppler shift is really a factor on the upper bands. You'll be spinning the dial constantly. I use my satellite tracking program (predict on my Linux system) to tell me what frequency I should be on. I haven't connected the rig to the computer yet, otherwise it would be automatically controlled.\n\nGood luck,\n\nGreg KO6TH\n\n\n> Date: Wed, 26 Nov 2008 02:37:35 +0000\n> From: [email protected]\n> To: [email protected]\n> Subject: [amsat-bb] AO-51 mode L/U\n> \n> \n> \n> I heard a few passes of AO-51 in L/U mode. Most stations came in strong. I tried to get into the bird using about 8 watts out into a 23cm horizontal yagi on an elevation rotor. It was to no avail, though the bird was at 50 degree's and higher. I am working on a CP antenna for mode L. \n> \n> \n> \n> Can those that worked this mode give me an idea of wattage, EIRP or antenna for Mode L that you are using. I was sure 7-10 watts would do from the Icom 910. However, it may have been the yagi and the lack of CP. \n> \n> \n> \n> Thanks \n> \n> Greg \n> \n> N3MVF \n> _______________________________________________\n> Sent via [email protected].
