Just finished a basic website for SDR++
Has links to everything related to the project and automatically redirects to the latest release or latest nightly build when clicking the download buttons.
(and yes it doesn't behave very well on mobile, will fix)

Small weekend project, a full M17 decoder for SDR++
I'm already mostly done, just need to make a fancy UI, finish the FEC decoding and setup the codec.

SDR++ Server streaming a HackRF over ethernet from a headless

. This really is how seamless it is. You get the remote source's menu directly in the UI. This works with unmodified SDR++ sources so all devices/protocols supported by SDR++ are available.

Who needs a scope when your FFT rendering algo is so efficient 😎
Here is SDR++ running its FFT at 15000FPS with the FFT algo and rendering done entirely in CPU. And with more reasonable speeds it can of course use a much bigger FFT size!

The scanner prototype is working and it is extremely fast. On airband with a 6 MHz bandwidth SDR it's able to reliably scan 2500 channels per second. This means it can scan the entire band in 0.3 seconds...
Demo soon!
(note: this is a temporary UI, not final at all)

Working on a complete rewrite of the SDR++ DSP to both increase performance and selectivity. I'm also fixing some bugs along the way and making the code easier to use outside SDR++.
Might take a few weeks but it's worth it.

Been a busy weekend of assembling my new 1.5m dish and making the parts for mounting the feed. The end goal is S+X band on a rotor. Mounted a vivaldi as a test and as expected the results are dreadful. I'll grab the materials I need for a S band VE4MA feed tomorrow.

After a month of exams, I'm finally getting back to the DSP rewrite of SDR++. And good news, it's basically almost done! It's now much more selective, much more efficient and has new features! The AM enthusiast will be happy to learn that the AGC now has a carrier option :)

Thanks to

IT WORKS! A bit of DSP fuckery (custom costas loop) and even the currently messed up signal of

, it yields almost perfect images! First is the normal demodulator, next is the one with the DSP magic :)

Ham radio operators hunt down people like you for sports. There is no such thing as "getting on the air license free" outside of purpose built FRS/PMR radios, especially when transmitting in ham and (worse) public safety bands. I think the
@FCC
may want to have a talk with you.
Programming the Baofeng by hand and getting on the air license free. No excuse to be without communications.

- Fixed FFT size change causing a crash
- Added PPM setting to RTL-TCP and RTL-SDR sources

I've got a working M1 .app (which means basically a one click install, don't need to mess with dependencies) version of the latest SDR++ with almost all modules included!
it now probably follows the MacOS standards instead of being a hacky linux-like mess...

demodulator(NOT decoder) plugin coming soon. It's fully compatible with LRPTOfflineDecoder.Still need to write a good UI for it and tune it for best demod performance.I'll add the decoding part as soon as it's done(that way no external software will be needed)

Since the IQ Exporter module has been pretty popular, I'm adding a Network Source to allow sending data to SDR++ from any software. Again, there is a predefined list of samplerates to avoid geniuses setting a prime number as the samplerate and wondering why it uses 50GB of ram...

Got my first HF transceiver friday. A Kenwood TS 850 SAT in perfect cosmetic and working condition. Had just been adjusted by WiMo a few months ago (according to the seller). I'll check the caps on the VCO and display boards just in case though...
Got a Pretty sweet deal imo 😅

The first version of the SDR++ scanner module is now available in the latest nightly!
It is only meant for range scanning and is a work in progress, so don't expect bug free operation for now.
You can add it through the module manager like usual.

Quick evening project, reverse engineering the serial protocol of those cheap RF power meters from aliexpress. Was tired of having to use dodgy chinese software for it, so I'll publish the library as well as a FOSS control program for it. Might include more advanced calibration.

Now testing the
#SpectranV6
at 245MS/s IQ and only 8 to 10% CPU usage (same benchmark as usual: Broadcast FM, 200KHz bandwidth, Stereo and RDS enabled). I think it can still be improved but it's already pretty good.

Thanks for this hilarious read. I've never seen someone so precisely ignorant in a subject before. HackRF being the best SDR and a blue RTL-SDR in the top 8? Seriously? Where are the Airspy, BladeRF, LimeSDR, Perseus, hell even USRP if you're looking for raw performance... (1/2)

First time I've sent a signal through a satellite! This is a very rough test literally pointing a wifi grid out the window with much less than 1W (my preamp is broken so the PA isn't putting out much). Also it's super unstable and inaccurate, haven't got the a GPSDO yet.

The waterfall and audio are perfectly fluid, no artefacts or glitches. World's first for a RSP?

Introducing the new SDR++ frequency manager. This allows you to create lists of important frequencies and switch between then quickly. It currently saves frequency, bandwidth and demodulator.

Currently working on a scanner module for SDR++. It'll be quite basic at first but will gain more features as time goes on. When this is done, I'll finish the noise blanker, maybe implement basic AF noise reduction and 1.1.0 will be ready for release!

Just added an Audio source to SDR++. It allows to play IQ from a soundcard. This is available on Windows and Linux. MacOS and Android will have to wait as they use a different API. This along with the soon-to-come rigctl client will allow to use soundcard based SDRs easily.

The first alpha version of SDR++ has been released! Keep in mind that this is an alpha (not even beta) version and can be very buggy at times ;) (don't scream at me if it keeps crashing lol)
Also, please check current issues before reporting a bug :)

I just relicensed the complete rewrite of the SDR++ DSP library as LGPL. This way it can be used in any software without requiring a GPL license.
SDR++ itself of course stays GPL.

This is the kind of abuse I have to deal with from users too stupid to read the manual for working around a bug caused by RtAudio. This is how people treat open-source developers and you wonder why we start to hate our users or abandon projects.

"Full waterfall update" feature I just added to SDR++. As its name suggests, it allows to update the entire waterfall history instead of just the new data. I'm sure it could come it plenty useful 😂
(once again, the UI is just for debugging)
PS: It can off course be disabled.

Yesterday I tried to speedrun a decoder for the SG-STV mode that was used today on the ISS. Unfortunately I only got the point of demod and FEC working. The spec is just too vague about the image block encoding to write software without reverse engineering. And that's a shame...

Releasing the first public alpha version of SDR++ tonight 🥳

Don't expect it to be super stable. It's mostly usable but still has a lot of random bugs. Feel free to try it and give feedback :)
