Anyone here have first hand experience using a Kenwood TS-590 with the DX Engineering RF-PRO-1B Magnetic Loop? I have been unable to get the relay actuation circuit to turn off the antenna pre-amplifier when I transmit. What menu items did you turn on/off with the TS-590? Did you use the "DRV" connection? Or something else? Did you have to change the dip switches inside power inserter?
