We are happy to announce that we are releasing the beta version of our new KrakenSDR Suite, which includes heimdall V2, and krakensdr_doa V2. The new code is written entirely in C++, so it is significantly faster than the previous Python based software.
The spectrum view is now real-time, and the Web GUI is a lot more responsive. The Web GUI also has WFM/FM/AM audio demodulation, scanning features and more.
Heimdall also has improved lag and phase convergence algorithms.
We have uploaded an image file here https://drive.google.com/file/d/1hR-RrXhLgLFimqfGLT0nXZzb_Ffzzl-m/view?usp=drive_link
The image works with both Raspberry Pi 4 and Pi 5 devices with 2GB or more. Like the previous images it connects to a hotspot from your phone with SSID: KrakenLink PW: KrakenLink (or legacy SSID: KrakenAndroid, PW: KrakenAndroid), or if there is no hotspot available it will generate its own hotspot with SSID: KrakenSDR, PW: krakensdr. You can of course connect it to your own WiFi network or an ethernet cable.
Note that the KrakenSDR web UI now requires HTTPS, so the link will be https://krakensdr.local:8080, or https://PI_IP_ADDR:8080. Heimdall now also has a web UI available at http://krakensdr.local:8080 or http://PI_IP_ADDR:8070.
The code is open source and available here GitHub - krakenrf/krakensdr_suite · GitHub
If you test it, please let us know your feedback and bug reports here. Again, this is beta, so there will be bugs and instabilities, but in our testing we have not seen many remaining issues.
