Avionics Bending: VHF COMM Radio

Over the past few weeks I have designed a multi-purpose I/O interface for the Lockheed L-1011 project that will allow me to attach a number of radio heads to X-Plane. The first radio head to attach to the flight simulator will be a VHF COMM radio. A few postings ago, I showed you the
breadboard prototype of the proposed electronics.

Over the next few days, I will take you through the following:

Posting 1: The schematic for the I/O interface
Posting 2: The PCB design
Posting 3: The finished PCB
Posting 4: The assembly and attachment of the PCB to the VHF COMM radio head
Posting 5: The radio head firmware
Posting 6: The computer receiver module
Posting 7: The X-Plane plug-in

So stay tuned, over the next few days we are going to go deep into hardware and software interface design.
