What may be indicated if a VHF radio operates normally but the transmitter produces nearly zero RF output in the high power mode on all marine channels?
A
The antenna system is presenting a Standing Wave Ratio (SWR) of 1.5 to 1.0 on the desired frequency.
B
The SWR protection circuit in the transmitter has engaged to prevent damage to the Power Amplifier .
C
A "crowbar" circuit in the power supply has prevented an over current condition that might damage the radio.
D
A 50-ohm impedance in the antenna system is preventing the transmitter from achieving full power output.
