Hello Everyone, I am new to the list (I'm sure you could have guessed that on your own) After 30+ years of being away from satellite work I have decided it's time to get back into it.. I used to work AO-6 AO-7,RS-15,ect.. Had an old Ameco TX-62 Xmit and used my "new" Kenwood 599D twins for downlink. I have looked for a week or better to find answers but still have several I can't find. I will be using the old (rebuilt) Cushcraft A144-T10 and a new homebrew 22 element 70 cm (11 vert, 11horz). 1. What circular polarization should I be using, LH or RH? I will not have polarization switching (at least not for a while) 2. What is good software for my Yaesu G-5400B rotator? 3. What is a good Interface for my Yeasu G-5400B rotator? 4. Need some good links for reference. thanks.. de wd9apy
