Unlike many other mobile Yaesus, this one uses RJ-45 (8 pin jack same as in Ethernet cables) instead of RJ-12 (6 pin jacks similar to the land line phones). On the positive side, the connector has the audio out from the transceiver so we don’t have to collect that signal with the separate headphone jack.
Here’s the pinout and info from the manual:
With that in mind, the Digirig cable should look like this:
RJ-45 pin 2 (RX AUDIO) → 3.5mm TRRS tip (RIG_AFOUT)
RJ-45 pin 3 (PTT) → 3.5mm TRRS ring 2 (PTT)
RJ-45 pin 4 (TX AUDIO) → 3.5mm ring 1 (RIG_AFIN)
RJ-45 pin 5 (GND) → 3.5mm sleeve (GND)
Please post your requests for this cable or reports of the homebrew builds.
If there is enough interest, I’ll add it to the store and announce here and in the mailing list.
