Hi i like to show you the remote yeasu control box. Yeasu is asking 500 dollar for a remote print to get it working. It is very expensive. So i have been looking on the internet and found Arswin. Arswin is a software program with a interface that works on a parralel port from the computer. So you need arswin to run first before making the rotor remotely connected. If you like the info just see the website from EA4TX to get more information.
