In the "Hatchet" book by Gary Paulsen, Brian doesn't use the radio to call for help because the radio transmitter in the plane that Brian was traveling in crashes into a lake. As a result, the radio becomes inoperable and cannot be used to call for help.
Here are some reasons why Brian is unable to use the radio:
1. Damage to the radio: The impact of the crash damages the radio equipment, rendering it unusable. Brian tries to use the radio after the crash but realizes that it has been destroyed.
2. Lack of power source: Even if the radio had not been damaged, it would require a power source to function. In the wilderness, Brian does not have access to electricity or a way to recharge the radio's batteries.
3. Remote location: Brian's plane crash-lands in a remote area, far away from civilization. The radio's range may not be sufficient to reach a signal or receive a response from any potential rescuers.
4. Unfamiliarity with radio operation: Brian, being a young teenager, may not be familiar with how to operate a radio effectively. He might not know the correct frequencies or channels to use, limiting his ability to communicate.
Given these circumstances, Brian is unable to use the radio to call for help in the "Hatchet" book. He must rely on his own survival skills and resourcefulness to navigate his way back to civilization.
