The first paragraph of the message text
The message number
The priority handling indicator for the message
The information needed to track the message as it passes through the amateur radio traffic handling system
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?
Change from vertical to horizontal polarization
Try to find a path that reflects signals to the repeater

They are too weak to go very far
FCC regulations prohibit them from going more than 50 miles
UHF signals are usually not reflected by the ionosphere
They collide with trees and shrubbery and fade out

T7B06: What should you do first if someone tells you that your station's transmissions are interfering with their radio or TV reception?
Make sure that your station is functioning properly and that it does not cause interference to your own television
Immediately turn off your transmitter and contact the nearest FCC office for assistance
Tell them that your license gives you the right to transmit and nothing can be done to reduce the interference
Continue operating normally because your equipment cannot possibly cause any interference
