[Motorola] Interface MTS 2000 w/Aircraft Comm System?

[Dave Marshall]

Ken,
I've done exactly the same thing in my plane (2M/440 FM but same
principle).  I'll have to do a little research and refresh my memory exactly
how I did it.  I've got a daughter getting married tomorrow, so I'm a little
swamped right now.  I'll try to look it up later this weekend.
