Re: Please help with udev rules - non-root GPIO for PTT

 

Each GPIO has properties and member of groups. Check the properties of
the particular GPIO you are using and either set it so everyone has
write access or that you are a member of whatever group it belongs to.

Thank you for that. The nice thing about Linux is that there several ways to accomplish a goal.

E.g., I use cron to both start and restart direwolf (if necessary) as user "repeater". Adjust arguments as needed:

# start at boot ...
@reboot sleep 10 && /usr/bin/screen -S direwolf -d -m /usr/local/bin/direwolf -c /home/repeater/direwolf.conf -L /home/repeater/direwolf.log -T "\%H:\%M:\%S \%d\%b\%Y"
# check every minute to see if it's running, restart if needed ...
* * * * * if [ x$(pidof direwolf) = "x" ]; then /usr/bin/screen -S direwolf -d -m /usr/local/bin/direwolf -c /home/repeater/direwolf.conf -L /home/repeater/direwolf.log -T "\%H:\%M:\%S \%d\%b\%Y"; fi

This again allows one to ssh from any device, type "screen -r direwolf" to observe activity, and Ctl-a Ctl-d to detach the screen session.

Thank you for this, Adam. I changed the systemd service on my pi to your configuration and it's nice to be able to use screen in an SSH session to monitor my digipeater's activity. I want to add that Control A followed by D (case-insensitive) detaches screen from monitoring Direwolf and returns you to the command prompt.

Hi David,
?
The audio problem has been solved in another message. Thanks.
I have the levels around 50 now. Radio output level is set to '2' on the Retevis and around 50% on the slider in the soundcard properties.
These are the two images after I made all changes.

Re: Direwolf 1.7 "plughw:" doesn't match any of the input devices

Hi David,
?
After adjusting the ADEVICE command for use with Windows all devices where listed with the asterix for the Digirig for both rx and tx as you can see in the picture I've added.
?
?
I put this line in de config file:
?
ADEVICE0 4
?
Before using Windows 11 I had a raspberry pi 4B running Direwolf and took that config file not knowing some commands differ so the line said:
?
ADEVICE plughw: 4,4

Re: Frequently setting when starting

 

¿ªÔÆÌåÓý

Hi Mike

My APRS system startup bash script on the vehicle Debian laptop starts rigctld then direwolf and puts them in background, then sleeps a seconds before running some rigctl commands to save/set opfreq. As I am only using it to TX posn on 30m every 10 minutes I have the transceiver toggle between the APRS and voice frequencies.

The second delay is about the rig setting VFO mode (inadvertently) on dw start, when I am actually using a rig memory. (which also covers mode and bandpass. I have also used it to "auto" QSY to the 2m APRS frequency then back to HF for voice)

Not within the direwolf conf file but works reliably.

The base script steps then;
/usr/local/bin/rigctld -m 3068 -r /dev/icom9100a -s 19200 -c 0x7c &
sleep 2
rigctl -m 2 E 1
sleep 2
/usr/local/bin/direwolf -t 0 -a 300 -X 1 -c /home/<user>/direwolf/hf-std-30m-inet-aprs-beacon.conf | tee -a logs/dw.log &
sleep 1
rigctl -m 2 V MEM

In my case the above is within a timed process kill loop, the end of which has;
rigctl -m 2 V currVFO

Hope this is helpful.

Cheers Bob VK2YQA

I have a ft-897 that I also use on psk31, hence the desire to set frequency apon start of direwolf ....

Or when choosing another radio setting for hf packet ... 300 baud at another favorite hf frequency?

But would still be the same radio

This might work with rigctl. I doubt this will work from within the
direwolf configuration file.



>Maybe even to FM

Also that should be possible, depending if the radio supports it.

Re: Good volume level to start with?

Hello Phil,

If I was to guess, you have the input mixer level on your digirig set to 100% listening to your Retevis radio.? Bring that input mixer level down to say 50-60% and then increase the radio's output audio level up to have Direwolf's heard audio level average around "50".?

Beyond that.. when you start Direwolf, send us the output of that window to see how it's starting up.? Also send us your direwolf.conf file to see if there are any other possible optimizations.

I'm using the same radio on VHF for APRS and WINLINK.
If you are using the correct Digirig cable for this radio, I set my volume to 2 on the Retevis. (VOL 1 is bearly hearable). I split the audio to the Digirig and a small Kenwood speaker. I'm using Windows 11 right now and my setting for the input is set to -3,5 dB. My packets are around 50% when received by Direwolf 1.7. But sometimes the RX is not working (other question asked here in this group). So I'm not receiving packets. It has worked before. It does work perfect with Soundmodem.

When you start Direwolf up for Window, it should list all the available sound devices.? You need to pick from that list and but the correct one in your direwolf.conf file.

Re: Direwolf 1.7 "plughw:" doesn't match any of the input devices

 

Hi Phil,

The plughw device name is specific to Linux. For Windows you will use different naming. See the section in the user guide titled?

"Audio Device selection - Windows". Should be found around Pg. 52 in the user guide.

That will walk you through setting the ADEVICE name for your system.

Hope that helps.

Re: Transmitting 100hz tone with dire for voice alert.

 

I understand your intent, but I recommend against it. I was strongly admonished for using a Morse ID on my digipeater.
If APRS users in your area are more tolerant, I suggest using an external tone encoder and some method to enable it during speech output. (I'm a hardware guy, the coding for this project is beyond my skill set).

The following command will synthesize a 100Hz tone:

ffplay -hide_banner -nodisp -autoexit -f lavfi -i 'sine=f=100'

There is likely a way to use ffmpeg/ffplay to mix this synthesized tone with the output of espeak but I haven't been able to figure it out.

Re: How to change APRS-IS connection port?

 

I'm working with Javaprssrvr application.? Pete AE5PL the author of the software suggested all clients use port 10152.
?
My DW clients are feeding the local server, but regardless of the server-side filtering I try, no traffic coming out of the server except on port 10152.
?
My testing is using a local server to allow multiple RF clients (LoRa, IL2P, etc) to feed a local/rural server in case the Internet isn't available.? The server can be ran on a RPi with AREDN.
Re: How to change APRS-IS connection port?

 

The first question is, why were you advised to do that? That port number is for when you want unfiltered full-planet feeds from the APRS-IS. Do you really need that much traffic flooding into your DireWolf instance? Remember, DireWolf's purpose is to be an RF TNC; it supports I-gate connections primarily so you can _contribute_ to the APRS-IS by forwarding received RF traffic to the Internet, and optionally re-transmit Internet traffic specifically addressed to RF stations you have heard. You really don't need to hear any other Internet traffic in DireWolf. Make a connection like that in an APRS display client like APRSIS32 or YAAC if you want to see planet-level traffic, but DireWolf won't present that data in a usable form.
