FCC Technician Exam Question Of The Day (T7C05)

Q) What is the approximate SWR value above which the protection circuits in most solid-state transmitters begin to reduce transmitter power?

A) 2 to 1

NJ2X Notes:
Remember, high SWR is something to be avoided.  Your equipment can be damaged while operating under high SWR conditions.  Automatic power reduction circuits are helpful; however, they do not cure the root cause.
