To use it you'll need Python 3 with PyQt5 and PySerial installed.
Edit the config.ini and set the LO in Hertz which in my case was my 70cm so 432000000
Example:
[CONFIG] LO = 432000000 PORT = COM10 BAUD = 38400 POLL = 0.01 RIG = K3S |
To start the application from the command line do.
python QO100uplinkVFO.py
If that'll be useful you can download the software from GitHub.
