Thank you to Stefan for letting us know about a relatively modern OpenWebRX fork by luarvique that comes with additional built in decoders and features, such as SSTV, AIS, CW, RTTY, an MP3 recorder and SSTV image browser.
OpenWebRX is an open source web based SDR receiver program that allows you or others (if you allow them to), to access your SDR over the internet. It is compatible with KiwiSDR, RTL-SDR, Airspy, SDRPlay and many other software defined radio hardware. It was originally developed by Andras Retzler, but since abandoned by him, with a semi-official fork being maintained at openwebrx.de. However, other forks like luarvique can exist that implement a new set of features.
The full set of additions and improvements reads as follows:
This is the package repository for the improved version of the OpenWebRX online SDR. The new and original features available in this version of OpenWebRX:
- Built-in SSTV decoder with background decoding.
- Built-in AIS decoder.
- Built-in CW decoder.
- Built-in RTTY decoder.
- Built-in MP3 recorder for received audio.
- Image browser for received SSTV images.
- Adjustable noise filtering based on spectral subtraction.
- Adjustable tuning step.
- Improved touch screen operation, with panning and zooming.
- Improved scroll wheel support, with tuning and zooming.
- Improved tuning in CW mode.
- Bandpass filter adjustable with scroll wheel.
- More reliable SDRPlay devices operation.
- Better map information, with distances.
- Better APRS map information, with weather.
- Configurable session timeout, with a policy page.
- HTTPS protocol support (requires SSL certificate).
The code comes packaged for Ubuntu 22.04 (amd64, arm64) and Debian 11 (amd64 arm64, armhf). There is also a ready to use Pi 4 SD card image available, linked on the GitHub readme. The original forked code can be found at https://github.com/luarvique/openwebrx.
According to discussion over on the OpenWebRX groups.io, the fork also runs on a Pi 3. In the image Neil Howard from the groups.io forum demonstrates an SSTV image he received with an SDRplay clone using the luarvique fork of OpenWebRX.
