Alinco DX-70 Cable

Which pre-made 8-pin round cable is available for the Alinco DX-70 hf xcvr? DIY cable?

At this time there is no pre-made cable for Alinco DX-70, but if there is enough interest I’ll add it to the repertoire. Please signup to email updates on the homepage to receive notifications about new items added to store.

I found this pinout for the mic connector (pins view side on the radio’s male connector or solder view side on the cable’s female connector). From the looks of it appears to be GX16-8F

Alicno Wiring Diagram

Based on it, Digirig audio cable will look like this:

GX16-8F pin 1 (MIC) → Male 3.5mm TRRS ring1 (RIG_AFIN)
GX16-8F pin 2 (PTT) → Male 3.5mm TRRS ring2 (PTT)
GX16-8F pin 6 (SPK) → Male 3.5mm TRRS tip (RIG_AFOUT)
GX16-8F pin 7 & 8 (GND) → Male 3.5mm TRRS sleeve (GND)

I’m ordering the connectors and will whip a prototype, please PM if you would like to give it a try.

From some of the ebay listings for mics/cables it appears that the same pinout is used in “virtually all Alinco, Icom, Kenwood and Yaesu radios that an 8-pin round type microphone jack”. This could be a viable option for those models that don’t have an accessory port.

I received a Digirig for Christmas and have several Alinco radios. I am interested if you do make the cable setup.

Got a confirmation from Bernie KB1DGY that the cable with the above pinout worked with Alinco DX-70. Please be on the lookout for the availability announcement in the mailing list.

This cable is now available in store:

Thank you, this is probably the one that I am waiting for to use the digirig for Echolink node on my old Kenwood TM-201A.

But, do we need a connection to the speaker behind the radio?

Pin 6 is for receive audio and connected on the Digirig side.
You can refer to radio’s manual to confirm that the audio output is available on the Mic connector.
If it turns out that many radios don’t have that, I’ll add another cable with the additional headphone TRS connector.

I got a report that this cable doesn’t work with Icom IC-756PRO2.
Upon inspection the pinout for the mic connector is indeed different:

This cable was confirmed on Alinco DX-70 and I copied the entire compatibility list of the mic that had Alinco DX-70 in it among others (see my first post in the thread). It appears that the list needs to be revisited.

I’ll be looking into this further, but if you already got the cable from the first batch for the purpose of using it with ICOM, please let me know. The pinout for other brands needs to be re-checked.

There is now a new cable listing for ICOM’s GX16 Mic pinout (pin 7 grounded) and using headphones plug:

Please email me if you previously ordered Alinco version of GX16 cable with the plan to use it with ICOM.

Did you have to use a separate audio cable for the DX 70? If not I am interested in how. I bought the new cable but cannot seem to get it to work. I’m interested in your settings for WSJTX and getting VARA to work also.

The cable supplied for the DX-70 is all that’s needed.

It’s the settings in Windows and the app, e.g. Winlink, VARA HF, etc. that are critical.

Recommend reviewing:

That’s what I used.

Also, suggest joining “digitalradio” in for more specific Q/A regarding the specific application.

There is now a variant of this cable available with audio pulled from the separate 3.5mm socket (speaker/headphones):

Digirig keys up Icom IC-25H

So if I’m following correctly, the Icom 8 pin round jack with 3.5 mm audio jack has not been made available yet. I can order a generic 8 pin to RJ 45 cable somewhere and then build a crossover RJ 45 cable to get the pins in order if this is still on hold. I have verified that the Digirig will key and deliver audio to the Icom 25H. This is not trivial as I have two other interfaces that will not key the radio. The only interface I have been able to key up with is a Buxcomm (no longer produced). I have not tried the Signalink, but I think it might. I have some sound card issues, so knowing the Digirig soundcard produces a strong audio is reassuring.
Here is a pic of my test bench with the mess of cables and jumpers used to test the Digirig on the Icom 25H which is the 50 watt version of the IC-25A. If you look at the mic jack on the radio and label the pins A through G clockwise starting at the 1 oclock position, I used:
Audio GND A
Mic Audio G

Obviously triple check this on your cable because documentation for the IC-25 is not as common as some rigs.

Happy to purchase a prototype if you have it and report back.


This is timely! @vwstuart is setting out to wrangle cables to be able to connect the Digirig and maintain the mic connection for the Alinco DX-70:

Any ideas for them?

Alinco (and others) has a mic extension cable to give more room to work . At some point there will need to be a mic splitter and a quick internet search reveals none of this type. So likely some custom cable builds, gender changers, converting back and forth to RJ45, etc. To buy it all would probably be pushing $100 if you can find all the pieces. 8 pin connectors are not that hard to solder using Cat 5 cable. I split my mic on a Yaesu and got audio complaints from the mic. It seems to work fine on my Kenwood and Icom. Maybe reconsider just putting the mic extension on and plugging in one at a time. Here are some pieces I put together to get my Ten Tec Scout to run digital. Notice the RJ45 splitter and gender changer in the middle which I use for different situations.

Good luck.

Question about using this with an Alinco DR-150. The 150 has a 2.5mm 9600 baud packet jack. (pg. 63 of the user’s manual: Do you know if connecting through the 9600 baud jack would allow me to use VARA FM wide? Would I need to rewire the cable to route the receive audio from the ring on the 2.5mm jack to ring 2 on the 3.5mm jack to the Digirig (instead of receive audio coming from pin 6 from the GX16 mic connector)? Thanks very much for any thoughts.
