Hello I am new to this group.? I tried this in the beta release 1.7 and when I run Direolf I only see my channel 2 ports?

In short :
ADEVICE? plughw:1,0
ACHANNELS 1

As I understand it, the goal is to use the connected mode packet radio protocol implemented in direwolf.
KISS is not capable of accessing this layer so it is necessary to use the AGW protocol.

I'm not aware of a turnkey solution but you might find these helpful:
src/agwlib.c? -? library to encode and decode the AGW protocol.
src/appserver,c? - sample packet radio server application.
src/tnctest.c? -? application which uses connected mode packet over AGW protocol.

Doug,

I've long started Direwolf from systemd and the significant difference I see between your Unit file and mine is I start "After=sound.target"? I used to start from screen as you do but for me, systemd's journalctl provides all I need, without additional complexity.

journalctl | grep direwolf produces output like this ....

I have a weather station and I want to connected to the aprs service using my existing I get and DG Peter can anyone with me in the right direction please thank you

Bi-directional interaction.

Also, are you stuck on AGW or are you willing to entertain KISS over TCP/IP?

Yes, I would consider using the KISS interface to software modems. Of course, that would require the terminal to implement most of the AX.25 protocol.

Hello John,

I'm aware of a few various packet programs for various OSes here:

Since you're only interested in AGW-based communications, there aren't many options.? BPQ32 for Windows might work for you here though non-GUI terminal program aka something running from the cmd prompt be it AX.25 packet, serial, whatever is VERY rare.? In the first link, there are tools like "telmgr" to translate TELNET to AGW calls.? If you have Linux running, any specific reason not to enable Linux's native AX.25 stack with Direwolf?? Once you have that running, you can use axcall, linpac, the console in FBB or JNOS, etc.

Perhaps try using the sound target instead of network?
After=sound.target

You might benefit from understanding why it's exiting. I'm not sure if you'll see the logs in journalctl if you're running it through screen like that. Maybe try adding -L to enable logging on screen.

I'm trying to run DW from a service on boot.? It starts and then stops.? I suspect it's stopping because the USB soundcard isn't initialized yet.? Wondering how to start the service after the USB soundcard is ready.? Here is my setup:

Can you recommend software to interact with a remote station from a command line, using the AGW interface to Direwolf? I'm aware of QtTermTCP and EasyTerm, but those are GUIs. I'm looking for something more like or , which you start from a shell and use like a shell, just by typing. I've heard of , but I'm told it doesn't work with AGW.

Something that works on Windows and Linux would be good. Short of that, I prefer Windows.

Hi All,

Its a custom modified cm108 originally built for AllStar

I have only seen this happen on the "communication device" with VOICE command active for microphone activity.
But I assume it may have similar capability on the speaker side.?
? ? Also, some devices have AGC for outputs - I think the speaker output was the issue.
I am not sure why the receive signal would mess with the sound card output volume - other than the COS.

Hello Matthew,

Which CM108-based device are you using?

--David
KI6ZHD

Are you talking about DINAH?

If so, you need to cut jumper JP3.? It is mentioned in the second paragraph of the Overview section in ? and a couple times in?? .

That is 'THE" most likely the cause and if you can disable the COS on the radio, it should solve the problem.
However, I will add one additional comment.? With Windows 10 and even more so with Windows 11, the "communication device" is often used for computer and computer-to-computer actions.
? ?Some of these applications don't show in the normal checks for applications that may be using the sound card.
? ?Also, there are times when Microsoft 'decides' to act on these devices - such as reduce background noise (prevent from sending to others).
? ?Double check the AGC setting (Sound settings for the USB device) - just to be sure.

Better yet, if you can - select something else as the communication device.? Unfortunately, I have not found a way to have that set to "none".
If your HDMI monitor doesn't have speakers, that is a great choice for one of the default that you don't want.

Hi Thomas,

Of course, that makes total sense. This sound card has COS hooked up to VOL DN. I'd rather not modify the sound card but I should be able to disable the COS output on the radio.

Thanks

Hi Matthew,

This is a somewhat common issue when using C-Media CM-108/109/119 based USB sound fobs/dongles. Some of the instructions (especially those for Allstar Nodes) for using C-Media chips as your radio interface include connections to the "volume up" (CTCSS) and "volume down" (Squelch / COS) inputs of the chip.

Depending on your intended use, those connections can be problematic because by default they will result in changes to the audio volume.

In many cases the only connections between the radio and the C-Media sound chip should be:
PTT (typically coming from GPIO #3 on pin 13)
Microphone Audio-In
Speaker Audio-Out
Ground.

Hi all,

I'm testing the 1.7A Beta Release on Windows 11 with a CM108 based sound card. For some reason when Dire Wolf receives, the output volume? of the CM108 reduces. On longer packets it reduces to zero and mutes itself.

I've looked in various settings, made sure no other programs are interacting with the sound interface etc etc but can't get to the bottom of it.

One observation is Windows has marked the CM108 as a "communications" device. There is a related setting buried in Windows to reduce the main volume when a communications device is in use, but I've disabled it and there's no change.

Has anyone seem something similar?

?

Thanks

Matthew
