Was able to create a working home brew cable for my AnyTone, but then developed a box to avoid swapping the Mic out every time I want to switch Voice to digital and back. I can also change frequencies or power settings without plugging and replugging the Mic. PS my bet is this will work with most Mobile radios but for a tweak here or there… Good luck…

Ty for the pinouts! Can you advise the best radio settings you have found to work with this, such as vox or ptt? Ty and 73
PTT for sure…Other than that just the normal recommendations from digirig. Nothing else comes to mind. On the other hand, If you ever make the connection I showed for a more permanent connection (no need to unplug the mic) and the ability to use the mic to change frequency, power, etc. in digital mode - Suggest you pull the jack out of the digirig to talk or it draws power and you will sound faint.
Thank you, very much. Been up and working like a charm for a few days now testing both Winlink and APRS. Have a great evening.
Greetings. Ty for manual. I went to some dissonance, please tell me.
According to CTIA standard of 3.5 mm jack, tip is left channel, ring 1 is right channel, ring 2 is GND and sleeve is MIC, but in your manual you wrote:
Tip to red wire —— speaker
RJ45 Pin 3 (green*) to White —— Mic
RJ45 Pin 2 (brown and white*) to green —— PTT
RJ45 Pin 1 (brown*) to Black —— Ground
At first, I wanna try this cable with external soundcard.
You are describing connections for two different devices.
CTIA is for the speaker/mic accessory (stereo audio output + mono mic) vs. Digirig (mono audio input and output + PTT). They are not compatible or interchangeable. Check out PTT cable, that will bridge the difference:
Thanks for the explanation!
I just wanted to add that my Digirig Mobile with this cable plus a shielded USB-A to C cable and a Raspberry Pi 3B+ with PiOS and Direwolf 1.7.0 installed on it let me use my Retevis RT95 as my area’s first and only APRS digipeater and igate. Everything worked flawlessly once I blacklisted the snd_bcm2835 sound card driver (which IIRC was for HDMI sound) in /etc/modprobe.d/raspi-blacklist.conf so only the Digirig’s sound card was available. (I think I had to create that file as root too but I don’t remember for sure.) That was my only stumbling block besides learning how to properly configure Direwolf, beacons, and so on.
Now my challenge is to try to get people in Cebu, Philippines interested in using APRS. 
. Anyway, the Digirig’s working flawlessly and will be my go-to digital mode interface unit for any future projects that require one. Thank you!
