Washington County ARES/RACES 
 
TM-271A Mods

The American version doesn't come with the packet data connector. Fortunately that's easy enough to fix.

You can open the rig by removing the plastic cover, the rubber gasket, and eight screws from the top. The pads for the packet connections are clearly visible on the left side of the board.

Hot-glue the wires after soldering to reduce stress on the joints and put a small cable tie on the cable just inside the notch in the case to keep it from getting yanked out accidentally. The wiring diagram for the connector is shown in the manual.
