    "content": "You're definitely approaching it in the right way, Bill!\n\nAn FT-847 is an excellent satellite rig, and in combination with a small \ngain antenna, will be an excellent station.\n\nThe 50 Watts the '847 provides is more than enough RF power, even with \nthe Arrow, or similar Elk, antenna.\n\nA preamps are highly recommended, especially with a smaller antenna.\n\nUse a diplexer \"in reverse\" to help get rid of desense. It's more \nimportant than you'd think.\n\n  http://www.amsat.org/amsat-new/articles/Mode-J/\n\nA few other tips to help you.......\n\nIf you're going to be running tracking software, like SatPC32, make SURE \nyour PC has the correct time set!\n\nAn error of 10~15 seconds may not sound like much, but it can cause you \npoint your antennas wrong, and ruin a pass.\n\nSame with your Lat/Lon. I use a GPS, which also supplies an accurate \nclock to the laptop, but a lot of people get by with just using grid \nsquares.\n\nKnow precisely *WHERE* North, South. East, and West are at your station \nlocation.\n\nYou'd be surprised how many people don't, and then can't find the sats \nas they come up over the horizon.\n\nHave a helper to point the antenna, as you'll be busy doing the \"Doppler \nDance\".\n\nAgain, if you run SatPC32, the Doppler correction is fed to the rig, and \nit's one less manual operation to split your limited time amongst.\n\nKeep the TenTec on the shelf, in the collection.\n\nAnd as somebody else pointed out, get started setting up and practicing \nNOW!!\n\nIf you wait until Field Day weekend, you'll wind up extremely \nfrustrated, with few or no contacts!\n\nI know, as I used to do it that way every year. I think the best I ever \ngot was three contacts one year.\n\nThe next year I started two months early, and I made THIRTY FIVE \ncontacts that year, just because:\n\nI didn't forget anything at home, requiring numerous unnecessary trips \nback and forth (I also bought some Tupperware tubs to keep all the \nsatellite stuff in!)\n\nEverything worked because I had six weekends to practice setting up and \noperating before Field Day, ensuring all the bugs were worked out\n\nI was a lot more comfortable using the station because I knew it all \nworked, and the stress level was much lower.\n\nGood luck, get going, and listen for K6AA on Field Day, and KQ6EA the \nweeks before while I'm practicing!\n\n73, Jim  KQ6EA\n\n\nOn 05/21/2013 08:09 PM, Bill W1PA wrote:\n> I may set up a Field Day satellite station for our local club.
