Is this the correct cable for a Yaesu FT-90R?
“Yaesu RJ-12 Cable for Digirig Mobile”
Thanks
Yes, RJ-12 cable looks right for FT-90R
Has anyone tried programming their FT-90 via CHIRP using this cable?
Current revision of this cable only supports audio and PTT lines.
From this page it sounds like the radio uses CI-V type serial port (supported by Digirig) connected to pin #4 or RJ-12 connector. Please let me know if somebody wants to prototype this with Digirig.

I have an FT-90 and will help with prototyping.
Awesome, looking forward to your report. The pinout needs to be confirmed.
Additionally to the connections to Digirig’s audio socket (audio + PTT), you’ll need to connect tip of the serial socket (tip) to CI-V line on RJ-12. According to the linked resource this is pin #4 of RJ-12 connector which doesn’t line up with Digirig sketch where it’s GND. Pin 2 is said to be GND.
Here’s the info on Digirig’s RJ12 cable with audio/PTT connections:
Let me know if you need help figuring out connections.
Here is the verified pinout for the FT-90r.

Looking at your drawing and comparing it to the manual this is for 1200 baud use, correct? For 9600 baud pins 2 4 5 6 are used and no ext spkr jack. Page 17 has the pinouts.
Yes, my config is for 1200 baud packet.
The FT-90R Operating Manual page 6 shows the MIC Jack pinout and page 16 shows the connections for 1200 baud packet setup.
I take it that I would have to roll my own cable, correct?
If there isn’t one in the store then yes.
