What cable for Kenwood 732A?
Thanks in advance!
Jorge
At this time there is no pre-made cable in store so this will have to be a homebrew build.
Because the radio has no accessory port we’ll need to get signals elsewhere. Luckily, according to what I can find online, the mic connector also has receive audio which simplifies our build.
The pinout would look like this:
RJ-45 pin 2 (RD) → 3.5mm TRRS tip (RIG_AFOUT)
RJ-45 pin 3 (MIC) → 3.5mm TRRS ring 1 (RIG_AFIN)
RJ-45 pin 5 (PTT) → 3.5mm TRRS ring 2 (PTT)
RJ-45 pins 4, 6 (GND) → 3.5mm TRRS sleeve (GND)
Please report the results if you end up building this cable.
Thanks Denis for your reply!
I’ll build it and report back to the forum!

Hey Jorge:
Did you ever build this cable? Did it work?
I have a 732a that’d I would like to connect. Where did you procure the phono adapter for the DigiRig? And, I, not sure which pins go to which connectors on the phono adapter.
73’s,

Hi Eric! In Denis replay is the key.
“RJ-45 pin 2 (RD) → 3.5mm TRRS tip (RIG_AFOUT)
RJ-45 pin 3 (MIC) → 3.5mm TRRS ring 1 (RIG_AFIN)
RJ-45 pin 5 (PTT) → 3.5mm TRRS ring 2 (PTT)
RJ-45 pins 4, 6 (GND) → 3.5mm TRRS sleeve (GND)”
You can fine the phone adapter in Amazon or for that mater even in a dollar store.
The adapter or cable has to be 3.5mm and TRRS.
TRRS means the adapter has a Tip-Ring-Ring-Sleave. Regular audio adapters/cables only has TRS (Tip-Ring-Sleave) only one ring.
Hope this help!

Thanks. That is super helpful. Maybe I will attempt it with some twisted pair CAT 5/6 cable. Did you have any luck? Or, did you pass on the project?
The Denis diagram. I assume, it looking at the radio and the female port into which the Cat 5 plug is inserted.
Thanks.

Follow the numbers on the RJ-45 connector.
On Denis diagram Pin 1 is show as DWN and Pin 8 as UP.
I not make my cable yet cause some health issues, but I will do it in the near future!
Good luck!
