Hello! Happy owner of a digirig for other radios. I was wondering if there is an existing cable that would be compatible with the Wouxun KG-XS20H, which is a tri band base/portable radio. It uses an 8-pin DIN style connector but I cannot find a connector schematic in the user manual.
If there is not a compatible cable, I hope you consider making one as there still aren’t a lot of 1.25m-band capable base/portable radios. Thanks! -Peter
I’m not finding the reliable source for the mic connector info for this radio, but it looks like it uses a common GX16-8 connector. You can use a continuity tester to see which pins have connection to radio’s chassis. That will likely match one of the existing GX16 cables from the store (see pinout info in the product pages):
Please post your findings.
Hi Denis, thanks for your reply. I have tested and only have continuity on Pin 7.
I triple-checked all other pins, but quadruple checked Pin 8 to make sure no connectivity there, as well.
So it looks like from what you posted, the Yaesu GX16 cable is the leading candidate? I assume I should purchase a 6.35mm to 3.5mm adapter for my radio’s speaker jack?
Thanks. -Peter
Following… were able to access Wionlink via your KG-XS20H? Respectfuly Harry KN6NXJ
Yes, it is worth the try. For additional check you can short pins 6 and 7 and see if the radio keys up.
For the adapter, you’ll need something with additional cable since the speaker jack is on the back, maybe this:
Ok thanks for the additional testing suggestions. The test was not as expected. Here is what happened when I tested each pin with the adjacent pin and each pin with pin 8. Hope you can sort out what this means.
Shorted pins 6 and 7: The display screen went all white and freezes radio. Radio restart restores normal operation.
Shorted pins 3 and 8: Radio keys up.
Shorted pins 5 and 6: Screen flickers. I think one time it detected a button press but unable to replicate.
Uh, could have been an expensive experiment. These results don’t correspond to any of GX16 pinouts that I remember. Also in pretty much all radios PTT is activated by grounding the line. It doesn’t sound like it’s the case here with your earlier test determining that pin 7 is ground.
We should probably source the pinout before trying the cable on the radio.
Understood. I have written buytwowayradios.com and Wouxun asking for the pinout info. Buytwowayradios initially wrote back saying simply “Unfortunately we do not have that information” but I wrote them back asking them to contact Wouxun to ask about it. We will see if I get any more info from the inquiry.
Hello K4KE and K0TX!
I have Wouxun KG-M70 which is dual band radio (2m/70cm) and it has also GX16-8 connector.
I am in interested in using digirig on my radio.
Have you obtained the pinout scheme for the connector?
I have contacted official Wouxun website with polite request for the pinout but there was no answer.
Let me know if there is some advance in this case.
Thank you, Hynek 9A3CRX
@suchyh, can you give this a try to determine which of the offered cables is most likely to have a matching the pinout:
Hello K0TX!
I have tested continuity and it has yielded same results: only pin 7 is connected to ground/chasis.
So I guess it is the same case as with K4KE!
Hynek 9A3CRX
Ah, right. That was discussed earlier. In the absence of the documentation, if you are interested in taking the next step, please share the pictures of both sides of the PCB inside the handmic and I’ll try to make sense of it. We’ll also need to ring the wires by color to the pins of the connector.
I will open the mic and take pictures of both sides of the pcb and will try to identify colors of the wires of the connector. It will take some time.
Hello Hynek, I just wanted to follow up and report that no, I was not able to obtain the pinout scheme from Wouxun or their U.S. distributor. I wish you the best of luck in your testing.
I have opened the microphone and tested connections in connector. Enclosing photographs and schemes.
Thanks for the pictures. I was hoping for a bit better documented PCB with some labels etc.
We can still try reverse engineer some of the signals.
My guesses are:
The copper pour connected around the mounting screws is ground.
We can check if these ring to the pins on the header and the functionally test the connected signals with the Digirig.
Hello K0TX!
I will check suggested connections to header. I cannot check with digirig, I don’t have one.
Hynek 9A3CRX
Understood. You can test with whichever system you are integrating. I would use 100-1000 ohm resistor in series while probing for the audio lines for good measure. This will prevent any conditions that can cause overload.
Hello K0TX!
This needs some clarification. I am interested in purchuasing Digirig and cable for my radio, that’ s why I asked for your help. So now I don’t have any system to test. Maybe there is some other way how to probe the audio lines. Also this resistor in series maybe needs some more explanation for me.
PTT connection I should be able to test with continuity measurement on my multimeter, is that right?
yes
