Since I am controlling the \nradio and rad-shack rotor manually, doppler and azimuth are too fast going \noverhead for me to track anyways. I also happen to use a little less \nelevation, which doesn't help the overhead part one bit! I think it's a \nnice compromise untill I can afford a new rotor system.\n\n73's\nAuke\nVE6PWN \n\n", "attachments": [] }
