My mobile APRS Digipeter doesn’t look suspicious at all… once up and running it pulls 0.11 Amps. With that 4.5Amp battery it should last 36 hours at 90% efficiency give or take. I can’t imagine trying to take this on a plane! #bioenno #aprs #digipeter #digirig #amateurradio #hamradio #packetradio #direwolf #photo

So far I’m liking the output of the APRS Foundations steps to document the protocol. I finally learned the correct format of the ACK message! Thank you for pulling together this report of info! :ack001

And thank you for John Langner (WB2OSZ) for documenting the protocol!

I think it's worth me doing a new #Introduction:

Hi! I'm Chris! I write code, I make things, and I parent.

My posts are generally about a few key areas: #Programming, #HamRadio, #TTRPG and #Parenting.

As far as programming, I mostly focus on #DotNet #CSharp professionally, with a smattering of #WebDev using #TypeScript. For my "not professional" development, I do a lot of #GameDev in #Godot (usually using C#, though not always!), and I adore #FunctionalProgramming, particularly in #FSharp, but also in many other languages! I stream software and game development on Twitch at https://twitch.tv/b4ux1t3. The schedule on there is not currently correct (January 2025), but should be soon.

When it comes to ham radio, I mostly focus on #DigitalModes, though I do a little bit of #POTA and #SOTA (well, I want to, anyway!). I'm a big user of #APRS and #PacketRadio. I try to be active on #YSF via the inimitable KJ7OMO@mastodon.radio's (edit: removed the mention here to prevent accidental mentions!) pride radio network, though mostly I listen. If you'd like my callsign, feel free to DM me. I do not list it publicly, but I'm not shy about handing it out in a more private setting.

Regarding TTRPG, I'm mostly a forever GM who runs #ShadowdarkRPG, #BladesInTheDark, #MorkBorg and #Mausritter, though I love most #OSR games and often mix and match rules and stuff. I don't _hate_ #DnD, #dnd5e or otherwise, it's just not the sort of thing I enjoy running. I also GM professionally on https://startplaying.games/gm/b4ux1t3!

Outside of that, some of my posts are about #Crochet, #BookBinding, #Woodworking, #Mathematics, #Linguistics, #TokiPona and, well, lots of other things

I have lots of links in my profile if you'd like to know more about me!

Oh I still own my Montreal Packet radio modem I built in 1980? on a 24 pin card for an AIM6502 I wrote my version of the Packet Assembly Disassembly PAD in 6502 assmebler and we communicated with the Montreal packet radio folks via a repeater.
Yes there are EXAR modem parts on that board.

Currently I am developing a cross-platform #PacketRadio client. Supported are Hardware TNC's via Hostmode and Soft/Sound Modems via AGW Server. The software is OpenSource and will be released next year. As you can see from the screenshot, the communication works perfectly. ANSI color codes are also supported. I will publish the features step by step in the coming months. Of course, I am also happy to receive feature requests from the Radio community. #hamradio #ax25

On #Network105 20m today. #hamRadio

I'll even add some context for anyone who knows less about #packetRadio than I! Basic info at https://www.qsl.net/ww2bsa/ww2bsa-network105.htm.
