sdrangel

Thanks to @srcejon this plugin demodulates and displays DSC messages used in maritime traffic. More details here

This plugin allows sending I/Q samples to a HTTP server connected to a IQ modulator and Spectran V6 Tx input in the RTSA Suite. This makes it possible to use a Spectran V6 analyzer with Tx as a transmitting device. More details here. For now it is not possible to use it during extensive periods (~30mn max) before the clocks drift too much and the Tx xtops working correctly. Aaronia is working on a more reliable solution and this plugin will be adapted to it in the future.

New sample source plugin to support reception with the Aaronia RTSA (Real Time Spectrum Analyzer) and the Aaronia RTSA Suite software. This is mainly targeted at the Spectran V6 series however it just interfaces with a HTTP server block fed by a IQ demodulator block in the RTSA Suite so any flowgraph supporting this architecture would work. Details are provided in the readme.

Contribution from Jon @srcejon (PR #1414)

The Remote Control Feature can be used to control and view the status of Smart Home / IoT devices, such as plugs and switches, and test equipment that supports the VISA API, such as benchtop power supplies, multimeters and spectrum analyzers.

In a SDR context, this can be useful for remotely controlling and monitoring power to SDRs, power amplifiers and rotator controllers. Or it can be used to make and display signal power measurements from a spectrum analyzer, in SDRangel.

Details here

Ubuntu package is now built for 22.04 and therefore Qt 5.15 and consequently compatibility with Qt 5.12 is dropped. You will need Qt 5.15 which is available on most current distributions.

Contribution from Jon with PR #1350. It implements #456 as it can be used to connect to a rtl-tcp server. This PR adds two new plugins: Remote TCP Input and Remote TCP Sink. They are similar to the current Remote Input and Remote Sink plugins, but use TCP rather than UDP.

Two protocols are supported:

• RTL0 - which allows the Remote TCP Input plugin to connect to rtl_tcp and rsp_tcp servers. It also supports Remote TCP Sink appearing as though it were rtl_tcp, allowing applications that use rtl_tcp to connect to a wider range of SDRs. This protocol is limited to 8-bit IQ data.
• SDRA - a slightly enhanced version of RTL0, that supports a wider range of device and channel settings and 16/24/32 bit IQ data, as well as the ability to send the remote device's settings when connecting so they can be displayed in the GUI. This protocol is recommend for when connecting Remote TCP Input to Remote TCP Sink.
