Application note Yaesu transceiver

e.g. for FT-1000, 1000D, (900)

This design can be used for all Yaesu transceivers with the 6 pin FIF-232 DIN socket. The logging software controls the transceiver over the serial or parallel port, and receives band information over the serial port. PTT keying is done with a RCA (Cinch) adaptor.
The FT-900 allows only limited functions at the moment, please ask for further developments.
