What condition may be indicated if a VHF radio is unable to contact nearby stations and an inline wattmeter indicates power outputs of 1 watt (LOW power) mode and 8.5 watts (HIGH power) mode with +12.8 vdc applied to the radio's DC line?
A
The AF Power Amplifier (PA) may be malfunctioning when the transmitter operates in the high power mode.
B
Negative feedback in the PA stage may be preventing high amplitude oscillations in the high power mode.
C
The transmitter output is low in the high power mode but it is still functioning within FCC specifications .
D
The transmitter output will increase in the high power mode with modulation between 75 and 100 percent.
