Icom IC-970H (IC 970 H IC970H) AFC Sat Control

Material
  • IC - LM 339 x 1
  • Resistence 22k x 1
  • Resistence 2,2k x 2
  • Green Led x 1
  • Red Led x 1
  • Pot 5k x 2

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.
