I am trying to put together a computer controlled az-el rotator system with BS2 processor control like KO6TH using U-100 rotors. With Orbitron for satellite prediction and Wispdde comunication I do not get data display on the LCD display. The display works for other program titles. I tried Nova (demo) thinking the BS2 needed different input but still nothing to display. I used Free Serial Port Monitor and could see ASCI output that looked like what I wanted with satellite name, AZ and EL with numbers but the values did not match the satellite tracking program, they never changed! This was true with both Orbitron and Nova. I am using Orbitron 3.71, Wispdde 4.2, 4.3.0.7 and 4.3.0.2 modified by AD5JN. I have tried all the Wispdde programs at 1200 and 9600 baud. My radio is a FT726 so there is no CAT control there to confirm operation of other equipment. I have tried BS2 programs off the web from KO6TH and SAEBRTrack with out success. My BS2 is rev G and I am using a SC-IOREL4 relay board to mount the BS2. Demo display and relay programs run fine. I do not understand why the data into the BS2 isn't the same showing on Wisp panel. Any thoughts? Gary AB3ID Snow Hill, MD
