(1) I can control my radio remotely
(2) I can rotate my Hexbeam remotely. This was enabled by installation of an ERC-H USB controlled interface in my Hygain Rotor Control Box. I made a short YouTube clip showing activation of the rotation from a tablet computer remoted into the shack computer.
(3) The only remaining task is to be able to select and tune antennas remotely. That should be complete October 31. By then I will have remote tuning and selection of 3 antennas (5W to 500W) and a 4th antenna (5W to 100W)
