Which of the following is one of the possible causes for a slow drift of frequency in a self
exited transmitter oscillator circuits resulting to a poor frequency stability?
A. Poor soldered connections
B. Power supply voltage changes
C. Loose connections in the oscillator, amplifier, or antenna circuits
D. DC and RF heating of resistors, causing then to change values.
