This is a simple guide for working FT4 mode via satellite with the help of SDR-Console software, a SDR receiver and Icom IC-705 as transmitter. The IC-705 can of course be replaced by any other radio that can be controlled via OmniRig.
The ”magic” is done by Omnirig. This smart little software can connect several software to one radio at the same time, in this case SDR-Console and WSJT-X.
This guide requires that you have basic knowledge of the following:
- WSJT-X and FT4 operation
- SDR-Console V3 satellite operation
- IC-705 operation (or other radio if you like)
- Audio piping between several software
- Basic operation with OmniRig
Step 1 – Setup SDR-Console and IC-705 with correct frequency
First you need correct frequency for SDR-Console and IC-705. You can download and use the prepared files from this site.
Start SDR-Console and set the downlink (USB) to the satellite you would like to use. Set the IC-705 to the uplink of the satellite, note it has to be LSB-D (LSB with data mode).
Step 2 – Config WSJT-X
Start WSJT-X and config as following:
- Rig should be Omnirig and your setup for IC-705
- Mode should be ”None” to avoid WSJT-X to set the rig to USB-D
- Soundcard Input should be the virtual audio from SDR-Console
- Soundcard Output should be the IC-705 mic
