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
