This is my current antenna setup: http://www.pa3guo.com/a7.jpg Basically, 6 ele for 145, 17 ele for 440, 23 ele for 1200, small quad for 23, and a multiband vertical. I am planning revise and clean this. AZI rotor kr400, 30 years old, 20 years by me, and 20 years in use. ELE rotor kr500, also 20 years in service. I know how to clean these rotors, but consider to replace the AZI rotor with a new one. Any advice? G450, seems less strong as the kr400. G650? G1000sdx or dxc? G5500? I do control these for sat tracking. Is variable speed in that case a disadvantage? Other thoughts? Here is a comparison table: http://kur02.com.au/index.php?option=com_content&view=article&id=23&... I tend towards a G650 which costs around 425 dollar here, the G1000 dxc is 600 dollar. -- Henk, PA3GUO
