In addition, a thought... Did you change the Pi's configuration when you tried to start it at boot, for example, making the Pi "Headless". Removing an HDMI display can change the order of sound cards,

After years of fumbling through the menus to adjust the Windows 10 Sound sliders every time I changed digital modes apps, I discover that each application has its own level setting. Go to Settings |

Hello Herber, When you run the dw-start.sh script from the command line, does it give any errors? What do you see in the /var/tmp/dw-start.log log? Only guessing here w/o seeing any specific errors

Hello I have DW 1.6 installed on Raspberry PI 3 b+ with and SDR dongle. If I call the program from the command line it works great. When I try to use the dw-start.sh script it will not start on the

Hello Dennis, Is this a new installation or is this a setup that has been running for a long time and it just started to have issues? Are there any specific log entries shown via "sudo journalctl"

I'm running version 1.6 on a Pi 3b+ and debian. I have noticed that sometime during the night, it appears to stop decoding packets. I will check the screen and I may see a lot of incoming igate

What you suggest sounds like an incredible amount of flexibility.? Let me first start by saying that I am new to python programming and have a lot to learn.? I do however have a fair amount of

If you are already using the PI, why not configure it to accept a certain message with certain content to control its GPIO?All that would be required on the PI is a simple, 'specialized' APRS client

I think you'd have to build a timeout timer into your code

This is one really cool piece of tech- the dual radio control board.? Not exactly what I was going for here though due to price.? I'm looking to cut the cost of a reliable pi tnc to less than or

This sounds like a winning solution.? Monitor the gpio that works with the sabrent usb soundcard and that would do it.? Does the activation of that gpio currently have any tx timeout or is that

By putting things on the i2c bus, it lets you manage multiple things vs one GPIO pin to one thing... [email protected]> wrote:

The day is coming though. This is exciting.

Edge of Space Sciences (www.eoss.org) in Colorado routinely flies high altitude balloons with multiple APRS beacons on the flight string for redundancy, etc.. Each of which is on a different 2m

Yes! Wild. It’s getting there!

Using basic tools like rtl_fm, no but when using say RTLSDR-Airband, you should be able to create multiple slices, pipe the audio through say netcat, and get it into multiple direwolfs. SDR# also now

I was just reading about this in the User Guide for Direwolf, in section "9.1.6.4 Gnu Radio – multiple simultaneous channels".? That seems to be in the spirit of what you are trying to do?

Is it possible to take an SDR listening to some segment of the 2m band, and decode 1200 baud packets on multiple channels at once? 144.91, 93, 95, 97, 99, 145.01, 03, 05, 07, 09, into 10 separate

Then just run that bit of python code as a service through systemd, and it'll happily sit in the background waiting for Direwolf to trigger the GPIO and do its thing.
