RE: Buddy Box Cord
MNHOBBIES is good to work with. I bought a number of items through him and the service is always great. In fact, I ordered an Airtronics VG400 through him to help out a flying buddy who needed one to buddy box with his Airtronics radio.
My solution when I wanted a buddy box to go with my RDS8000 was to simply buy another RDS8000. That way I got an extra receiver and I had a spare transmitter in case my original RDS8000 ever needed service. Two RDS8000s programmed identically for the same model is a pretty sweet buddy box setup!
