What is the correct adjustment for the LOAD or COUPLING control of a vacuum tube RF power amplifier?
Pick an answer to check it.
Answer: D. Desired power output without exceeding maximum allowable plate current
The LOAD or COUPLING control is adjusted to get the desired power output without exceeding the tube's maximum allowable plate current. It is not about minimizing SWR on the antenna.
Tip: Load for power, within plate limits.
