@npub18yt…f75r Threw together a simple Rust program to brute force these. It works but is very slow. How long did it take you to generate the list you posted?

I wonder if you could run pci-e over a bunch of SFP fiber links. It's differential signalling and I think you get two lanes per SFP. I wonder if it would actually work in practice

Do 1 bit FIFO memory chips exist? A quick search says they're obsoleted by microcontrollers, but what if I need something relatively quick? (~100MHz)
May have to design my own using some SRAM, shift registers, and a bit of glue logic

@npub15zk…s5wp It's a CATS companion - it's designed for CATS: https://cats.radio
Not much info on it yet, I still have a lot more to do

2024-04-04 22:53:37

Current status of the CATS Companion. Haven't had a ton of time to work on it, and there's still lots to do. I'm not using a real gui library, so re-implementing everything I need using primitives is taking quite a while. The latest project was completely rewriting the display driver to use DMA - this sped things up significantly and has solved the lag problem

@npub1dp9…z3n2 Yeah, the biggest issue here (aside from them often landing hours away) is that if they're more than about a km from a road, they're pretty much impossible to get

@npub1qnn…zdec In North America I believe it's 400-406MHz. You can use sondehub.org or auto_radiosonde_rx to run your own station

@npub1dp9…z3n2 Yup! They launch every 12 hours from Maine and depending on wind patterns, sometimes they land near-ish to me

2024-04-03 21:21:33

Got another DFM-17 radiosonde! This is my second one. Landed relatively close to my house, though it was still about 45 minutes of driving each way

CATS, in the palm of your hand! Spent this weekend writing a GUI library that I can use to develop the rest of the software. Just the textbox alone took hours - so many edge-cases and I had to rewrite a lot of stuff. Definitely has some rough edges I still need to fix.
There are other issues - the screen refresh rate is slower than I'd like - but not bad for a bit of free time this weekend. #hamCATS #CATSradio
