I have had several inquiries lately regarding the wiring diagram for the
Yaesu part number D40000019, which connects the FL-7000 amplifier to the FT
990 and FT 1000 rigs.
Here is the info.
One end of the cable goes to the Band Data socket on the transceiver. It has
an 8 pin DIN connector on it. The other end of the cable has a Molex
female, nine pin receptacle. It is Molex part number 3061092. Radio Shack
(special order) parts number 910-2748 available from www.radioshack.com for
about a buck. (IT IS NOT THE 274-239 9-PIN MOLEX available in RS Stores!)
Use 8-conductor SHIELDED cable to make up the cable.

This will NOT work with the FT 980
