What is indicated if a VHF radio fails to receive nearby stations and a voltmeter connected between the positive side of a radio's DC line and ground reads zero line voltage? The fuse in the VHF radio also reads zero when checked with an ohmmeter.
The antenna may be defective or water intrusion has affected antenna system performance.
The coaxial transmission line may be open, shorted, or a connector has become intermittent.
A fault in the discriminator circuit is producing zero output voltage during peak modulation.
Correct Answer
A "crowbar" circuit has prevented an over currentcondition that mightdamage the radio.
