I think the radio visualizer has developed nicely and now there are band edges for the broadcast FM range. Really hoping to publish it to cargo soon but there's still some things I want to fix and add. #rust #rustlang #sdr02 May 2025 20:07 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lo7mt7tnq22hhttps://bsky.app/profile/73s.bsky.social/post/3lnqnlzms6c2xAs part of the work I'm doing on my new SDR radio thing, I released a Rust library for handling the Winamp skin format. The crate can unpack skins and generate a mockup screenshot from them. It also makes it easy to access the sprites programmatically. crates.io/crates/wsz #rust #rustlang26 Apr 2025 21:11 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lnqnlzms6c2xhttps://bsky.app/profile/73s.bsky.social/post/3lnh6rk5inc2rOPN's garden of delete album goes so hard23 Apr 2025 02:51 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lnh6rk5inc2rhttps://bsky.app/profile/73s.bsky.social/post/3lngjvoabrk2cI went down the rabbit hole on rtl-sdr last night and found this wonderful deep dive superkuh.com/rtlsdr.html . People did some great research back when these devices came out. https://superkuh.com/rtlsdr.html22 Apr 2025 20:38 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lngjvoabrk2chttps://bsky.app/profile/73s.bsky.social/post/3ln3fjbn3x22uMy WIP #sdr application now has scanning! This feels like a big step towards being a "proper" radio. Next up will be band plans and then hopefully some narrowband FM stations too. #rustlang #egui18 Apr 2025 10:20 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3ln3fjbn3x22uhttps://bsky.app/profile/73s.bsky.social/post/3ln3eetmtr22uThis code is nasty. This code is fetid. This code is disgusting. I need to clean up this code.18 Apr 2025 10:00 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3ln3eetmtr22uhttps://bsky.app/profile/73s.bsky.social/post/3ln3c6tvzws2uI'm kind of surprised that #rustlang mpsc channels have no way of checking the length of the queue. I guess you could implement this yourself by keeping a counter on the sender and receiver sides and then sync them up, but it feels kind of cumbersome.18 Apr 2025 09:21 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3ln3c6tvzws2uhttps://bsky.app/profile/73s.bsky.social/post/3lmxskwa27c2cI feel like my FM de-emphasis filter isn't quite right. Does anyone happen to know if FM broadcasts typically have this kind of spectrum after de-emphasis? (left: before, right: after). I used a very basic Butterworth IIR filter to but it feels like the slope is too steep. #sdr #radio17 Apr 2025 00:03 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lmxskwa27c2chttps://bsky.app/profile/73s.bsky.social/post/3lmxf3jkpos2kWorking on this has been my fixation for the past few weeks. It's an SDR application dressed in a Winamp skin. There's still quite a lot that needs doing but it's also exciting to see where it is now. I didn't demonstrate it in this video but it does support the Winamp skin format. #rustlang #sdr16 Apr 2025 20:02 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lmxf3jkpos2khttps://bsky.app/profile/73s.bsky.social/post/3lmaysltml22eI've been steadily making progress on a little Rust app that turns an rtl-sdr into an FM station receiver. The twist is that it uses Winamp skins. I'm hoping to demo it soon. I've got the 12-band equalizer working but I still need to make the classic visualizer. It's dumb and gimmicky but I like it.07 Apr 2025 22:23 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lmaysltml22ehttps://bsky.app/profile/73s.bsky.social/post/3llq63n4yzs27Getting FM decode in uda felt like a good milestone.

I've managed to get more than 65% test compatibility with liquid-dsp so far. I would like to go back and clean up the module organization and docs soon. Just added agc and FM demod which should be useful for uda. #rustlang #sdr24 Mar 2025 20:14 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3ll5kztbahs2lhttps://bsky.app/profile/73s.bsky.social/post/3lk7iyido2s27This is the first video I've made of the SDR library I've been working on. There's not much here, and I still have all the "Hello World" egui bits attached to it, but there are plots. One little step at a time. #sdr #rust #egui12 Mar 2025 21:17 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lk7iyido2s27https://bsky.app/profile/73s.bsky.social/post/3lk2fc57amc2nProgress in the uda SDR library continues. Recently I looked into how to render a large waterfall plot on the UI using egui. I wrote a little post going through some of the options I tried. https://cqcqcq.bearblog.dev/rendering-pixels-in-rust-with-egui/ Having a spectrum plot really makes it feel like it's coming together :D10 Mar 2025 20:28 +0000at://did:plc:sof6hwwnanyp7lwtipnfeyvk/app.bsky.feed.post/3lk2fc57amc2nhttps://bsky.app/profile/73s.bsky.social/post/3ljnvvtelac23Last night I got to a new milestone on the uda library. After working on it for a few weeks, I can now build a generic graph very much akin to gnuradio. There are not very many cores yet, but I do now have a demo of the graph pulling samples off my RTL-SDR and doing an FFT on them.
