In the search for a way to control my Hy-Gain rotors, i found many different solutions on the market.
The one i will describe are the ERC controllers (Easy Rotor Control) by DF9GR.
The ERC rotor controller is capable of working with up to 2 rotors at same time.
They will work in AZ/AZ or AZ/EL configuration – Very nice!
For old rotors, not capable of RS232 commands you will need a “rotor card”, also supplied by ERC Team.
I ordered a ERC-M USB kit and 2 rotor cards for Hy-Gain Rotors.
