To prevent power supply ripple from damaging a circuit
To interrupt power in case of overload
To limit current to prevent shocks
All of these choices are correct
The larger fuse would be likely to blow because it is rated for higher current
The power supply ripple would greatly increase
Excessive current could cause a fire
All of these choices are correct
Detect phase modulated signals
Demodulate FM signals
Detect CW and SSB signals
Combine speech and RF signals
To reject signals outside of the desired passband
To combine signals from several stations together
To shift the incoming signal to an intermediate frequency
To connect the receiver with an auxiliary device, such as a TNC

VHF signals lose power faster over distance
The shorter wavelength allows them to more easily penetrate the structure of buildings
This is incorrect; VHF works better than UHF inside buildings
UHF antennas are more efficient than VHF antennas
Change the batteries in your radio to a different type
Turn on the CTCSS tone
Ask the other operator to adjust his squelch control
Try moving a few feet, as random reflections may be causing multi-path distortion
