Anytone 6666 interface to Android

Hey All, new here !

Getting back into HAM radio and looking for a way to interface a 10m radio via digirig to my android phone using FT-8 app.

The radio is an Anytone 6666 - i can get raw audio from the speaker jack at the back of the radio.

The front six pin mic connector i can get mic line and ptt. A cable could be made i am sure…as the radiomis low end and has no cat control…treating it like a down and dirty HT connection.

Ideally i should also be able to connect the android s20 ultra via cable to the digirig and using a Y usb cable provide off phone power via battery to the digirig


This should be pretty straightforward. I found this pinout:


Based on it, the cable should look like this:

GX pin 1 (MODULATION) → 3.5mm TRRS ring 1 (RIG_AFIN)
GX pin 3 (TX) → 3.5mm TRRS ring 2 (PTT)
GX pin 5 (GROUND) → 3.5mm TRRS sleeve (GND)

3.5mm TRS tip (SP) → 3.5mm TRRS tip (RIG_AFOUT)
3.5mm TRS sleeve (GND) → 3.5mm TRRS sleeve (GND)

Hopefully the receive works without need for RX line activated. You can test that by running the radio without mic plugged in and confirming that you get RX audio on the speaker.

You can start with one of the store cables (RJ-45 or RJ-12) that have similar layout and replace the MIC connector.

Anytone 6666 with the digirig and the FT8 app, works on Samsung S20 Ultra, howver pinout anove is wrong.

Pinout should be pin 3 not 2.

Audio is live from the rear speaker without the mic connected

Anecdotal info: All seems to work better with volume set at 15

Given the proximity to the antenna to the cables, i was getting some RF in i believe, a toroid on the USB from phone to digirig worked.

Lastly, the Y usb cable i have will not deliver power to the digirig or phone - need to find one.

Possible solution to keep phone charged while in use is a proximity charging plate in lieu of plug in.

Nick, thanks for the info. I’ve updated the pinout.
