This Logic board is design and tested for Icom IC-970H and Yaesu FT-736R, however other radios can be used with it.

I have decided to install mine inside of the radio.

To use it with Yaesu FT-736R use the following connections:

Microphone Pins

 
Pin 2 = +5 Volts
Pin 1 = UP Key
Pin 7 = GND - Ground
Pin 2 = DOWN Key

Don't forget to adjust 5K Pots to center Sat Frequency.
