Also had the Drake \nSC-2 receive converter for modes T and KT... Made lots of Q's with some \npeople who were very amused at my \"hollow state\" station! Not sure if your \nAllied receiver is quite as stable as the R-4B was after it had warmed up \nfor a half hour or so, but hey, my first SSTV and RTTY SWL'ing was with an \nold Hallicrafters S-41G (talk about drift...) and a Radio Shack Color \nComputer...\n\n73,\nGeorge, KA3HSW\n\n\n----- Original Message ----- \nFrom: \"Tyler Harpster\" <[email protected]>\nTo: <[email protected]>\nSent: Tuesday, February 06, 2007 9:49 PM\nSubject: [amsat-bb] AO-07 RX - TX more questions...\n\n\n> With my ARR 28 MHz preamp sitting here beside me and plenty of plans for\n> antennas, I have a few more questions:\n>\n> 1) Can I really pick up AO-7 with my antique Allied Communications tube\n> receiver if I put the preamp at the antenna?\n>\n> 2) How much EIRP do I need on the uplink?
