9-7A1 C
 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.
