Automatic Direction Finder, or ADF is a basic instrument that transmits location information on the AM band. To use, tune it to a non-directional beacon (or NDB). The arrow on the ADF will always point to the station.
ADF is daisy chained with DME, NM, KT and Transponder.

Thanks, I didn't realize that they were set up differently than the com/nav set. I will have to wait until the new chips arrive to complete the build, then on to the buttons and encoders. How did you space the LEDs to the proper height for the face plate? the rotary switch seems a bit high. Second question, the Com/Nav group has an encoder that seems like it should be a pot not encoder, can I leave the encoder in place? I will post some picks of the card build so far shortly.

I suggest you print the faceplate and then solder the leds so you can adjust them as needed (same with the rotary switch which will tell you how high to solder the displays as well). Regarding the Com/Nav yes it is a potentiometer which was intended to turn off the radio and dim the lights. If you are going to go with buttons with leds, you can use that pot, otherwise it will be there just to simulate the look of the real radio.

What value pot or do you have a part number already?

So there won't be anything in the com/nav pot holes? or is it the same but no switch, or mount them to the faceplate and wire them to the board? I don't plan any back lighting or lighted switches at this point.

If you won't use backlight, than use an encoder for decoration purposes. You can solder the encoder to the pcb.

Cool, thanks. maybe the volume pot and switch will be the first mod. ;-)
