Great to see that the HydraSDR packages are now available in Debian Forky and SID packages.debian.org/search?searcho… Lets see when it will also be present in Trixie #sdr @hydrasdr

A nice full pass from Meteor M2-3 on this rainy May day at EM00 Kerrville. HydraSDR, SDR++, SatDump, and my 1M dish.

Hey Scott if you want to share the IQ capture (contact me in PM), I've got a dedicated LoRa encoder/decoder I built from scratch. Works across all modes and actually exceeds spec: it decodes down to -25 dB SNR at SF12, where the spec only calls for -20 dB. Happy to run your capture through it.

@pe0sat @amsatdl First test w/ gr-lora_sdr repository (github.com/tapparelj/gr-l…) output a correct decode! TX'd my callsign from an Arduino-R4. Used their example 'lora_RX.grc' & customized for my SDR hardware (@hydrasdr) & output preferences. Modified GRC: dropbox.com/scl/fi/s4bwnul…

And then there were three! Another sat from the 5-Feb-2026 launch of Russian Military satellite 'Cosmos-2600' w/ the same LoRa parameters as the 2 previously found, but #3 in the area of 430.630 Mhz. If anyone has info on these ride-along sats, please speak up

inspectrum-ng v0.5.4rc0 is out ! github.com/hydrasdr/inspe… What's new: SI suffixes now work everywhere. Type "10MHz", "125u", "2.5G" directly into Sample rate, Pos X, Offset and Period fields. Dropped the QDoubleValidator that was blocking k/M/G/m/u/n keystrokes. All physical-unit fields parse through parseSIValue uniformly. Sub-1 values keep their precision. formatSIValueSigned now handles m/u/n/p prefixes. Symbol period read-out used to collapse to "0.000s" for typical us..ms periods, now correctly shows "125.0us", "1.5ms", etc. #SDR #DSP #HydraSDR #inspectrum

Good results with the new Hydra SDR setup. MetOp-B today 2026/04/26 14:50UTC.

@DL8LAQ @ea4gpz @pe0sat @VERON_Nederland @IARU_R1 Do not hesitate to create an Issue if you can reproduce it with latest nightly build github.com/hydrasdr/inspe… You can create an issue here github.com/hydrasdr/inspe…

@ea4gpz @pe0sat @VERON_Nederland @IARU_R1 inspectrum ng v0.5.3-rc2: Is there anyone able to move the Time Selection cursor just by typing in an Offset of eg. 10.40000? That does not move the cursor. I only can use the mouse.

What is activated on 70cm that is causing this interference being received at multiple locations in the Netherlands ? @VERON_Nederland @IARU_R1 can this be a Wind profile radar ?

@ea4gpz @DL8LAQ @pe0sat @VERON_Nederland @IARU_R1 You should definitely try latest nightly github.com/hydrasdr/inspe… there is also a crash dump logs for any platform, if you reproduce any crash (so far I have stress tested it very hardly and never reproduced any crash ...)

@DL8LAQ @pe0sat @VERON_Nederland @IARU_R1 No idea. I use regular Inspectrum. I tried inspectrum-ng once trying to get a larger FFT size than what Inspectrum supports. I wasn't able to, the UI for the new options was somewhat confusing, and the thing crashed on me. So I've never used it again.

@mrTeigen @MehdiHacks I guess... I can try making a port also for the ECO. Here is the link for the new SAN90 as the SDK is different from the current line for the moment: youtube.com/watch?v=nx1Mwp…

🚀 New RF Swift images v0.1.6 out! ✅ URH-NG and Inspectrum-NG now default ✅ Signal Hound SDK (BB60/SM200/SP145) ✅ Firefox pre-installed ✅ CyberEther v1.0.3 ✅ Better ARM64 & RISC-V support ✅ Rust ≥ 1.85 Pull & enjoy 🎉 rfswift.io #RFSwift #SDR #RF #OpenSource

@corelyse_net I've done a cleanup and rebuild of the CI/CD pipeline the nightly prebuilt binaries are back, now on the latest v0.5.2. github.com/hydrasdr/inspe…

@hydrasdr the prebuild version vanished 👀👀 It was there yesterday

inspectrum ng v0.5.0 (fork of inspectrum v0.4) 22 new features: binary/hex/ASCII overlay, auto ASK/OOK symbol rate, session files, bookmarks, IQ WAV, spectrogram PNG export, tuner crop & resample, SI units, FFT zero-padding. All known crashes fixed. Heavily optimised. Builds on Windows, Linux & macOS Pre-built version available on github.com/hydrasdr/inspe…

New version v0.5.1 available in nightly build github.com/hydrasdr/inspe… For more details see github.com/hydrasdr/inspe…

@n6rfm @cemaxecuter Feedback is always welcome ! There's a lot of work behind inspectrum-ng v0.5, and it's provided for free to the community. Hope you find it useful !

@hydrasdr @cemaxecuter THANK YOU!🙏

🔓 URH-NG is in beta; Universal Radio Hacker, Next Generation -> github.com/PentHertz/urh-… 327 protocols. 23 automotive ciphers. New Signal Analyzer. New SDR hardware. And it plugs directly into RF Swift.

@vk5qi If you can share in PM the iq file (the Chirps look like LoRa) I can analyze and decode it with hydrasdr-lora tools which support analyze and decode sf5-sf12 with all different options...

Whatever it is, it appears to be transmitting every 10 minutes, starting 4 minutes past the hour (e.g. 00:04, 00:14, 00:24). Given I can still hear it, it's probably someone local experimenting.

No inter-lane skew. All decoders consume the same sample buffer from the same ADC clock, so they're inherently phase-coherent at the input. Each decoder independently tracks its own STO/CFO during preamble sync, but that's per-stream synchronization state, not cross-lane drift. SIMD lanes are lockstep on the same data. Channelization offsets are deterministic. The real engineering challenge isn't skew, it's keeping 1024 independent sync state machines fed without stalling the pipeline.

@hydrasdr That many decoders in parallel is impressive. Timing skew across lanes?

LoRa RF Visual Autopsy. Coming soon hydrasdr-lora enterprise-grade framework for HydraSDR SDR. Bare-metal C99 SIMD scanner. Up to 1024 parallel decoders brute-forcing every SF, BW, channel, sync word... Real-time/Recording/Replay Open-source edition TBD #LoRa #SDR #HydraSDR

@amoswap @QVHenkel That swappable frontend is where all the cost hides. LNAs, filters, matching, layout iterations... You spend more on band-aids than on the ADRV itself. HydraSDR RFOne delivers the RF performance upfront, no frontend gymnastics, at a price that makes the ADRV route hard to justify

@hydrasdr @QVHenkel Most of the drone applications will have a custom frontend put in front of it - the flexibility is in just having that part easily swappable.

Who needs a WiFi module if you can have a 6GHz (40MHz BW) SDR instead 😄 I've received some requests to add a capable radio to the high-vibration resistant variant of the PiMX8, so this version will feature an ADRV9002- and XCAU7P-based SDR. The FPGA interfaces with the iMX8M plus via PCIe Gen3
