🔍 Key Concepts

• Relationship between keying speed (words per minute) and the rate of on/off keying in radiotelegraphy • How bandwidth is affected by how rapidly a carrier is switched on and off (keyed)** • Difference between bandwidth of emission and signal strength (power)

💭 Think About

• When you key the transmitter faster (more words per minute), what happens to how quickly the signal must change from ON to OFF and back again? • In radio theory, do faster changes in a signal generally require more, less, or the same frequency spread (bandwidth) around the carrier? • Does changing the speed of the code automatically increase the power output of the transmitter, or is power controlled by other settings?

✅ Before You Answer

• Be clear on the definition of bandwidth of emission (the range of frequencies the signal occupies around the carrier). • Separate in your mind: speed of keying vs transmitter power (signal strength)—they are different characteristics. • Ask: which options talk about bandwidth, which talk about signal strength, and can both change together just by increasing code speed?
