Once you have uploaded from the radio (or loaded a saved image from the model you are using) you can disable transmit by:

1 – click “Settings” on the extreme left (There is a column that says “Memories” and “Settings” – click on Settings)

2 – click on “Other Settings” in the second menu column

3 – Change the VHF and UHF frequency limits as desired (e.g. 144-148 and 420-450)

You can disable transmit all together by unchecking the boxes next to VHF and UHF “TX Enable”
