Well… today was quite a wet and rainy day. Not a lot of activity here other than blowing the dust off an AX.25 stack I've been working on for a little while. This is written in pure Python and implements both AX.25 and APRS standards, including connected mode. It's shipped as a library to include in your Python (asyncio) applications.

I'll probably do a release soon, as I've spent the day refining the API a bit and cleaning up the unit tests. I've finally now got 100% code coverage on this and it's being tested on Python 3.9-3.14.

One thing I'm considering is some sort of stream socket protocol (TCP, AF_UNIX and maybe websocket) that can be used to expose the functions of the stack to a separate program. Something like the AGWPE protocol in concept — but different as I don't want any legal trouble. I also think the AGWPE protocol is a bit limiting.

OK, so last post I talked about #hamradio and #ax25. I said more on NET/ROM. Well, I thought NET/ROM would let me connect to a distant station that my station couldn't hear through some routing protocol.

It looks like it doesn't work that way?

Does anyone actually use this? It appears I have to connect to a node, and try to find a path manually to where I want to connect, if that's even possible at all. No concept of default routes, etc...

Revive #ax25 #packetradio on #CBradio keyboard-to-keyboard in 2026?

lets go!
QRV - JO76 - 27,235 MHZ (CH24) - 1200Bd - FM

(would USB and 300Bd be better? I guess, but less popular. Can hardware TNC's even do that?)

So I've made significant progress on my #hamradio #ax25 packet station. Last post I mentioned that I was using my Yaesu FT991a. My goal was to have a dedicated VHF radio and antenna, and finally I have that.

I'm running a Compactenna 2m/440+ antenna on my RV roof, an ICOM IC-V8000 radio, a Digirig, and Direwolf. I'm using the Linux AX.25 kernel networking code!

My latest endeavor is learning about Net/ROM. More on that later...

Ich habe schon länger das #Reticulum Netzwerk [1] auf dem Zettel, weil das auch Datenaustausch über #PacketRadio (#AX25, #KISS) verspricht [2].

Sieht leider so aus, als wenn die Software im #Amateurfunk nicht legal einsetzbar ist:
"It is not possible to send unencrypted packets to any destinations in the network" ([1])

Die Entwickler scheinen auch ziemlich klar darin zu sein, dass sie jegliche Workarounds wie das Abschaltbar-machen der Verschlüsselung oder das Veröffentlichen der privaten Schlüssel nicht unterstützen werden. [3]

Schade.

#HamRadio

Ich würde mir ja eine App wie bei #Meshtastic / #Meshcore für #APRS wünschen.

Also eine Möglichkeit, einfach und komfortabel über Bluetooth am Smartphone Nachrichten zu schreiben und zu lesen, die dann durch den #Amateurfunk-Transceiver ausgesandt und zwischengespeichert werden.

Ich denke, eigentlich müsste man dafür nur einen ESP32 so programmieren, dass er das Meshtastic/Meshcore-Bluetooth-Protokoll spricht, das ganze Knotenmanagement macht und dann über normales #AX25-#KISS-#PacketRadio mit einem Transceiver spricht. Zumindest Meshtastic hat bereits einen #HamRadio-Mode, in dem die Verschlüsselung deaktiviert wird, somit sollte auch regulatorisch dem nichts entgegen stehen.

Denn, ohne jemandem auf die Füße treten zu wollen, am Spruch "Life is too short for QRP" ist schon was dran. Nachrichtenaustausch mit Signalen knapp über der Grasnarbe kann unglaublich frustrierend sein.

I've released FlexPacket v0.8.0 with a lot of fixes and new features.🎉 The list is to long for mastodon. 😅 So, here are just some points:

- ADD: Editor to write multiline messages.
- ADD: [mail] Offline mail support for LinBPQ.
- ADD: [convers] Separate window for convers.
- ADD: Progressbar to show the state of message/file download.
- ADD: External software can use FP as PR modem via pipes.

Thinking of getting an FT-991A. I like the fact that it's all band and all mode. How is it with digital modes like JS8? AX.25? What about CW?

Is the fan replaceable with a Noctua without soldering?

I've released v0.6.0 of APRSMap with a lot of bug fixes and some new features.🥳

- CHANGE: PoI data move into seperate tab
- ADD: Window of the last seen APRS objects.
- ADD: [raw] Show RAW Messages from APRS objects.
- ADD: Weather charts.
- ADD: Support for RS41 Ballon probes.
- FIX: ModeS airplane visibility.
- FIX: Wrong APRS overlay images.
- FIX: Delete old PoIs

At altitudes above 30 km, the hardware used here for weather probes appears to have problems.

By the way, APRSMap now displays data from RS41 weather probes. Of course, only visible when data is available.

If there is any other hardware that you would like me to include in APRSMap, please let me know. 🙂

@JSkier Meshtastic nodes are fun, but I've only used them with the flaky #android app. I have plans to flash them so they can do plain-old #AX25 and #reticulum.

Two more nice features.

1) Progress bar for message and file downloads.
2) When FlexPacket displays the BBS software, it should also support offline mail reading.
