he doesn't need the trainer cord. He needs the actual buddy box.

wzak29,
Unfortunately it looks like the dedicated Airtronics buddy boxes are sold out. But if you look around you might find somebody with an Airtronics radio you can use as a buddy box. You can use just about any Airtronics radio all the way back to the Vanguard radios as your buddy box here. Ask around your club and see if anybody there is flying an Airtronics that will help you out.
