Smallest computer I’ve ever built!
Fits in my hand, 13x14cm
The build was easy
ODROID-H5 SBC
Intel Core i3-N300 processor
16GB RAM (up to 64GB)
1TB NVMe SSD (4 slots)
It’ll run NixOS in headless mode

My FT8 decoder is open source, MIT:

Pure Rust FT8 Decoder - Vox Tenuis
Clean-room implementation. Zero lines of WSJT-X. Thread-safe. All Rust.
Just logged the first ten QSOs with it!
It's just my FT8 decoder paired with my FT8 Terminal User Interface (TUI)

FT8 Terminal User Interface (TUI)
I vibe-coded an FT8 program, just got some of my first QSOs with it!
WSJT-X is *NOT* running, although this program *DOES* very much use the WSJT-X audio encode and decode functions, which were extracted into a library.

That was my coding spot today, working on a thing, not ready to talk about it just yet 😏

You can just make TUIs

WSJT-X wrapper library for encoding/decoding FT8/FT4 was updated.
This C and Rust library wraps WSJT-X's FT8 and FT4 encoding and decoding functions.
Why? So you can create standalone FT8 programs while still embedding WSJT-X's encode/decode functions.
Download Tegmen here:
https://w4ho.com

2025-12-25 23:33:01 GMT

Just released: WSJT-X FT8 encoder and decoder available as a library for C and Rust, called Tegmen.
Tegmen encodes an FT8 message and then decodes the generated .wav file. It uses the WSJT-X source code version, 3.0.0-rc1.

I don’t know, but from what I’ve read, people using Meshtastic tend to not have other Meshtastic people within range.
That seems to be the largest issue I’ve read about.
Just one ham’s opinion! 😀

I would say no. Portable to me just means you’re carrying your radio somewhere on your person to operate somewhere.
(As opposed to mobile, which seems to mean your radio is in a vehicle.)
Whereas Meshtastic is a low power radio system with cool capabilities that could be in a fixed position, portable, or mobile. 😀

Ahhh, Arca is just the name I gave my personal AI. Like Jarvis
It’s just Ollama running locally on my Mac.
My Rust code captures my input, sends it to the local Ollama, gets the response, displays it.
The Rust code maintains a history of the convo and things about me so the the LLM has a “memory” of me.

2025-06-08 14:39:26 GMT

I wrote a Rust program to have a 2-way chat with the AI running on my laptop, named Arca:
Me: Let's play a game. Limit your answers to 8 words or less.
Arca says: Sounds like fun! I'm ready, let's go.
Me: What's your opinion about ham radio?
Arca says: Cool hobby for tech-savvy people.
Me: I like it, too! My call sign is W4HO.
Arca says: Nice to meet you, W4HO!
