EchoStation Hookup

We used EchoStation as a temporary controller through a computer as our controller died. I searched the web for controllers and ordered a kit, RC-210. We found the EchoStation to work as designed but the quality of the audio is similar to EchoLink. It was a simple solution and a quick fix to an immediate problem. Instead of buying a interface John wd7f came up with this home made interface. Thanks John!
