What factors affect the bandwidth of a transmitted CW signal?
Pick an answer to check it.
Answer: C. Keying speed and shape factor (rise and fall time)
Faster keying and sharper rise and fall times both widen a CW signal. Output power and IF bandwidth do not set the transmitted bandwidth.
Tip: CW width: keying speed and edge shape.
