37 Final Conclusions All equipment at the station is controlled directly over the ethernet, - no PC is required at the remote site. Equipment used includes:, Lantronics serial ethernet servers for rotor, wattmeter, and Alpha 87A, Ten Tec Omni VII. Antenna switching is automatically through a band decoder interfaced with the rig. Audio is handled directly via the Omni VII, with near zero latency.
