    "content": "Hi Ron,\r\n\r\nI too am relatively new to this (and not enough time to pursue it). So \r\nfar I have just done some FM satellite work with an FT-60R and an 817 \r\n(two radios for full-duplex) along with an Arrow antenna. I'm thinking \r\nabout saving my pennies for an 818 to go with my 817 for two-radio \r\nlinear satellite operation - or I may just use an SDR for my downlink \r\nradio - we'll see. Like you I've thought about an 857 as a second radio \r\n- not so much for satellite use but for higher power HF field use - \r\nagain, we'll see.\r\n\r\nAs to rotators, this Australian school group has some interesting \r\nrotator projects for the DIY'er. I have not tried to build one yet but \r\nthe projects look approachable. They have other interesting radio \r\nprojects as well.\r\nhttp://www.sarcnet.org/projects.html\r\n\r\nI have also become interested in omni-directional satellite antennas \r\nlike lindenblad, turnstile, or helical and I may try building one of \r\nthese (which I suspect are much better at receiving than transmitting, \r\nespecially at low power). There are lots of plans on the Internet.\r\n\r\n73\r\nKen VA7KBM\r\n\r\nOn 2018-10-29 3:02 PM, ronald mosher wrote:\r\n> A very sincere thank you to all who replied to my post (below).
