T2C07: What should you do to minimize disruptions to an emergency traffic net once you have checked in?
Whenever the net frequency is quiet, announce your call sign and location
Move 5 kHz away from the net's frequency and use high power to ask other hams to keep clear of the net frequency
Do not transmit on the net frequency until asked to do so by the net control station
Wait until the net frequency is quiet, then ask for any emergency traffic for your area
T3A05: When using a directional antenna, how might your station be able to access a distant repeater if buildings or obstructions are blocking the direct line of sight path?
