multimon-ng VS direwolf

I have little experience with decoding radio signals so I don't know if any software decoders are expected to handle the clipping. I tried using multimon-ng and found that its UFSK1200 demodulator can get something out of the audio, but it also keeps repeating Error: stop bit is 0. Bad framing if verbose mode is enabled.

Sorry I gave wrong name, it is multimon https://github.com/EliasOenal/multimon-ng and is capable to decode:

It's likely that the signal is extremely strong. You can probably just pick it up with a short antenna indoors. I used MultiMonNG to decode. It's was pretty boring to be honest.

Give multimon-ng a whirl. This is CLI based, but can output what it decodes to a simple text file or hex data to do what you need with.

multimon-ng

POCSAG, FLEX (pagers), Morse, APRS and more with multimon-ng

multimon-ng for decoding various protocols.

Try this tool; https://github.com/EliasOenal/multimon-ng - It's CLI and you'll ideally want a Linux, but this can decode an awful lot more data modes like such.

144.800 is the APRS frequency in Europe. That's part of the 2m amateur band, and you can use tools like Direwolf to decode the packets. See https://aprs.fi/ for a display of the packets that make it to the internet.

Yes, recommended. https://github.com/wb2osz/direwolf

Since you're trying to save money, I'll second the direwolf software TNC. There's packet-radio.net with info about setting up direwolf.

By default it should be printing any successfully decoded packets to the terminal window. Did you follow https://github.com/wb2osz/direwolf/blob/master/doc/Raspberry-Pi-SDR-IGate.pdf or similar?

I use Direwolf with a Pi Zero and I believe there is a way to get the packet data out or passed to a script. I was going to look into this myself as some point as I wanted to just have a small screen on the Pi just to see traffic passing though my iGate on occasion.

Hardware TNC's were a thing in the 90s but nowadays software TNC'S such as Direwolf are far more efficient

On this topic, has anyone here used direwolf (https://github.com/wb2osz/direwolf) to communicate between two computers without radios?

Wheel successfully reinvented :)

Nothing stopping you setting up a whole AX.25 network between multiple machines using Dire Wolf [1] and the built-in AX.25 [2] (a derivation of X.25) support still in the Linux kernel. You get a proper network interface that shows up alongside eth0. Nice short instructions at [3]. Just don't hook it up to radios unless you're appropriately licensed. Speakers and mics only.
