If a transmitter is adjusted for maximum power for telegraph, what must be done to be amplitude modulated?

🔍 Key Concepts

• AM (amplitude modulation) vs. continuous wave telegraph operation • Effect of plate voltage on output power and tube dissipation in a transmitter • Relationship between carrier power, modulation, and tube heating

💭 Think About

• When you add amplitude modulation to a transmitter already set for maximum CW (telegraph) power, what happens to the tube’s average power dissipation if you change nothing else? • Why might engineers deliberately reduce plate voltage before applying full modulation to a final power amplifier? • Which option(s) describe a necessary change, and which describe a consequence if no change is made?

✅ Before You Answer

• Identify which choice is talking about an action you must take vs. a result that would occur • Think about whether maximum CW plate input power leaves any safety margin for additional heating from modulation • Check which options are internally linked (one is a cause, the other a consequence) and whether that combination fits the question wording

Question 1 of 27070

If a transmitter is adjusted for maximum power for telegraph, what must be done to be amplitude modulated?

The plate voltage must be reduced

The plate voltage must be increased

Tubes would have to dissipate 1.5 times as much power if the plate voltage were not reduced

Both A and C
