This little widget exploits the latest QMX CAT codes ( LCD read, power, swr ) to give PC control and visualisation. It previously used FLRIG XMLRPC but now connects directly to the QMX.
The code has been modfied to send frequency data to SDR++ program via its rigctld emulation server; should an SDR++ instance not be runnign ( or not have the rigctld running it quietly ignores it) This therefore adds a bandscope to the QMX. If this is enabled it sends commands to the QMX to ensure audio card is in I/Q mode.
It may be run from a single composite JAR file but requires a configuration file:
java -jar qmx.jar config.json
See the release assets for these files. do edit the JSON configuration file before you run it.
Note: If you want to use the band scope then download sdr++ and have this running first and ensure that: (1) SDR++ is running with sound card ( audio ) input connected to the QMX presented sound card. (2) SDR++ RigCTL server is running and the address/port match that in the configuration file. see SDR++ manual
Parameters are input as a configuration file in JSON format:
{
"Callsign": "G0FOZ",
"rigctldAddress": "localhost",
"rigctldPort": 4532,
"qmxDevice": "/dev/QMX07"
}
Configuration parameters
| Parameter | Example value | Description |
