  1. So what's new in the world of digital ham radio? This could be a big deal and might knock proprietary protocols and waveforms on the head. #Mercury #Hermes #opensourcesoftware #vara #packetradio

    Good news for Linux ops too!

  7. Today a Video about my PacketRadio Software called "FlexPacket".

    Sorry @scott, still no PR sound. 😅 It's a 9k6 connection. But in the next PR Video, I will show my APRS Software and then you will also get the great sound of 1k2 PacketRadio. 😃

  13. 44Net wasn’t just built online: it was built in person. In the early days, regional coordinators helped operators modify radios and build TNC’s for packet operation. This hands-on approach is still part of the community today. #44net #44yearsof44net #amateurradio #packetradio

  14. Late night #APRS #bike ride with my budget #PacketRadio setup. 14 miles around the #Illinois State Capitol. Baofeng with a magnetic mount 2m/70cm antenna on a pizza pan in my rear basket.

  15. The backbone of 44Net is IP address space, but the heart is sharing notes, fixing links, and helping newcomers get on the air. That was true decades ago, and it’s still true today. #44net #44yearsof44net #packetradio #amateurradio

  16. Can't get #DireWolf to actually transmit the packet audio burst via my FT-991a. I have this config setting:

    ADEVICE  plughw:CODEC,0

    Which corresponds to these devices:
        VID  PID   Product                          Sound                  ADEVICE        ADEVICE            HID [ptt]

    Bus 001 Device 017: ID 08bb:29b3 Texas Instruments PCM2903B Audio CODEC

    I'm listening in on 144.390 MHz on my handheld while my FT-991a is transmitting, but all I get is the transmission starting and ending with no audio inside it. Any suggestions?

  17. Anyone know why #DireWolf is hellbent on using /dev/ttyS0 with hamlib? I have this in direwolf.conf, which should force it to use /dev/ttyUSB1:

    PTT RIG 1035 /dev/ttyUSB1 38400

    But it refuses:
    Dire Wolf version 1.7
    Includes optional support for:  gpsd hamlib cm108-ptt
    
    Reading config file direwolf.conf

    If I make /dev/ttyS0 a symlink to /dev/ttyUSB1, it works flawlessly. What gives? :/

  18. 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.

    codeberg.org/sjlongland/aioax2
    github.com/sjlongland/aioax25/

    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.

  19. Volunteers have helped manage 44Net since its earliest days, when packet radio linked local networks. The ‘Regional Coordinator’ emerged to help support new operators and manage infrastructure. #44net #amateurradio #packetradio #amprnet #44yearsof44net

  20. Looking to see what is interesting to do with #PacketRadio ... I was really into it in the 90s for sending messages to family across this country, and I now have a VHF station up 24/7. I read the BBS, and get a message here and there.

    What else can you do on packet radio?

    If you want to make it really cool, respond via Packet.

  21. Just stumbled on this tonight looking around for information on UUCP. So, my loony idea at the moment, is to see if I can funnel UUCP over AX.25 packet radio, with the idea that I can send email over that.

    My principle gripe right now is that most UUCP implementations (I've dealt with SCO UUCP and Taylor UUCP) require you to list up-front, all the nodes you might want to talk to… but aside from that limitation, the technology choice seems sound on paper.

    Here, a group has managed to make UUCP talk over ARDOP.
    rhizomatica.org/hermes/

    ARDOP has its own problems, but that project looks interesting in what they've achieved. They're using conventional Icom HF radios to provide both text, recorded voice and photo transmission between communities in the Amazon (the rainforest not the megacorp).

  27. 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...

  28. HF packet radio on M2 macOS with Xiegu X6100, direwolf, hamlib, and paracon (quick notes)

    Install Stuff

    Configure Stuff

    • update direwolf.conf with call sign, name of audio devices, and PTT setup
      • ADEVICE "USB Audio Device" "USB Audio Device"
        • Those are actual names, not placeholders
      • PTT RIG 3087 /dev/cu.usbmodem53620077003
        • Xiegu X6100 is hamlib rig 3087
        • Device list can be found with ls /dev/cu.* and copied into the line
        • This probably changes every time you plug it in?

    Get Going

    • plug X6100 (dev) into computer
    • assuming direwolf config folder at ~/direwolf:
      • run cd ~/direwolf & direwolf
      • run python3 ~/direwolf/paracon_1.3.0.pyz
    • Paracon: AGW connection
      • AGW host 127.0.0.1
      • AGW port 8000

  29. 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.

  30. 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.

  31. @sacha @screwlisp @dougmerritt @zagebo @vavakado I'm trying to figure out how to maintain a wireless terminal connection with my home computer up to 10km away (further's edge of town)

    I'm not sure where this is going if anywhere ¯\_(ツ)_/¯

  32. 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.

  33. 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. 🙂

  34. 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.

  35. FlexPacket will get a separate Convers window so that you can “surf” in PR without missing any messages in Convers.

  36. @W1CDN is really putting packet radio on the map.

    That's all I'm gonna say at this time.
