# CaribouLite Simple RF Sweep Generator for CaribouLite HiF channel
|
|
# Sweeps a range of RF frequyencies on HiF channel (1-6GHz capable)
|
|
# User interface sets sweep start freq (in KHz), end freq (in KHz), sweep rate (in ms), and step size (in Hz)
|

# by K7MDL March 7, 2024
|
|
# derived from soapy_synth.py example program
|
|
# requires PySimpleGUI - use pip to download anmd install the package
