When I am using my radio for programming, setup within my house, experimenting, etc, is there anything special I should do?
You should ALWAYS extend your antenna at least the bottom or first segment when turning the radio on with a module in place. The 9Z's synthesized module, FSS, is particularly sensitive to this. If left in the radio with the radio on at your work area with the antenna collapsed for more than short intervals, the FSS will be unnecessarily exposed and may shorten the life or even immediately damage the FSS module.
