First, the audio interface. This is a no budget setup so something like Signalink is out of the question. I've got a couple cheap USB audio interfaces that have mic in and speaker out jacks. Will those work with direwolf?

Second is PTT. The Quadra has no I/O pins or serial port to trigger the PTT. The radio does not have VOX, which I would not use anyway.

Next, is direwolf usable with other digital modes than packet/APRS, like fldigi or WSJT-X?

Thanks for any suggestions/advice.

Direwolf has an option to use the GPIO of a CM108 sound card.? It requires taking the sound card apart and adding a resistor coming off a pin of the chip, and transistor to control the PTT.
Look up CM108 PTT and you should find some instructions.? I don't bother with SQL as the Direwolf is much better at checking if a signal is coming in.

Another option would be a cheaper interface than a SignaLink-USB.?
DINAH is at least half the price, and there may be others.

Hello Thomas,

maybe someone can answer me the question please, I didn't find anything in the documentation.

What do the zeros mean in the line?
K7MBBS-4 audio level = 19(4/4)? ? 000000___

K7MBTS audio level = 99(32/21)? ? __|||||__

You have enabled FX.25 reception and that's showing that 0 bits were corrected in each of the slicers described here on page 9:

Re: Cross Fix to ALSA-LIB and GPIO PTT issues

#8598

Hi Dave,
? I went over the ptt.c file and compared the debug output I had for the Direwolf startup. There didn't seem to be any errors as it follows the libgpiod syntax completely. My guess right now is that the GPIO pins aren't identified in the dtb table for the kernel startup. I've translated three versions and see no reference in the dtc's for a simple GPIO I/O interface on the external pins. Most of the defined pins are used for chip-chip interaction. So now I have to "re-invent the wheel" and do a dtc blob for my GPIO-19 pin on gpio@209c000 (the first bank of GPIO modules) and a gpiopin@209c000 definition with the needed pinctrl and pin-gpios data. The iMX6 reference data from Technexion is forthcoming as I've hung on my access and login, TBD. Unfortunately the other iMX6 ARM users don't leave their dtc files lying around for me to plagiarize.

Hasta,
Dave

Yes, there are automated regression tests.

A Mac development expert (which I am not) will need to address the other concerns.

Hello Andre,

I bought 10 CM-108 so one for my first I-GATE site which works well

I am attaching a photo of my CM-108 key, because a picture is worth a thousand words

there I want to build another one and I have no audio ???

I don't think it's a counterfeit, it's written CM-108 on the chip

Luc,

Do you have a real CM108? Or one of the counterfeits (where they conveniently put a dab of paint on the chip so you can't read the part number)? I have found that the counterfeits can jam up and refuse to work. The only solution is to literally unplug the USB connection so the board powers off, then reconnect it. If that doesn't work, get another device. The counterfeits fail easily.

I have a few sections in my doc starting at that should help here to test your CM108 sound device with using standard sound tools, etc.? Give that a try and report back if you get it working.

Wow, indeed, good idea to check the performance of my CM108, I hadn't thought of that

but sorry there is no audio output from my CM108

Direwolf -x a

I can't hear anything in my headphones

in Direwolf I also activated the CWID and I can't hear the CW ID either

meaning again it could be the SD CARD

What do you think?
