Starting with the WIA (Wireless Institute of Australia) CHIRP files,
edit out the states you want and add the simplex frequencies.
Rename your file to: ft1807.csv

Run my python script: python3 p1907.py
and it produces: ft1807C.csv 
This can be "Imported" after you have read you radio.
Note, your channel numbers in the CSV are ignored. It puts
channels after the last channel read from the radio.
So, start with a "blank" radio.
