Remote SDR v5
Web based Transceiver “Remote SDR” is a web application allowing to remotely control an amateur radio transceiver between 1 MHz and 6 GHZ. Its first application was the duplex control of a station allowing...
QO-100 Satellite Live
Since version 5 of Remote-SDR, it is possible to share its reception channel. You can connect to my transceiver to the QO-100 satellite. Of course, you won’t be able to transmit. If you are...
RTTY
Since version 4.5, Remote SDR offers the possibility of receiving and transmitting messages in RTTY. Starting RTTY mode A click in the “Digital” selection box opens a window dedicated to RTTY mode. Then click...
Troubleshooting
Raspberry / Orange Pi not starting Issue After burning an image to an SD card, the processor does not start. Solution 1 Very often, it is a weak 5v supply that is the source...

SSTV
Remote SDR makes it possible to do SSTV broadcasts by interfacing with software adapted to this mode of transmission. Here we will focus on MMSSTV and YONIQ. VB Audio Virtual Cable To interface the...
WSJT-X – FT8
Remote SDR can be interfaced with digital processing software like WSJT-X to make FT8 transmissions for example. WSJT-X not only processes transmit and receive audio signals, but can control Remote-SDR frequency and transmit on/off....
Omnirig – Remote SDR
Omnirig is an interfacing application to control different transceivers by a third party application like (YONIQ-SSTV, WSJT-X…) . It controls, for example, the transition to transmission or the reception frequency. Architecture Many amateur radio...
Communication Ports
For those who would like to open ports to communicate with the outside world, since version 5 of Remote SDR, all communications (audio, video, parameters) are done in https on port 443. This is...
Tone generators
On the transmit side, different tone generators are available to tune the transmitter or open relays. 800Hz Tone Selecting this generator disconnects the microphone and injects a 800Hz audio signal to its maximum. This...
Setting of GPIO outputs
It is possible to set the GPIO outputs according to the reception or transmission frequency. This is applicable for configurations with one or two orange PIs. This makes it possible to switch relays, for...
Band Scanning
It is possible to define one or more scanning zones of the reception band. The system automatically locks onto the correspondent and changes it every 10 seconds. With the mouse, it is possible to...
