T7C05:

Why do most solid-state amateur radio transmitters reduce output power as SWR increases?

  1. To protect the output amplifier transistors
  2. To comply with FCC rules on spectral purity
  3. Because power supplies cannot supply enough current at high SWR
  4. To improve the impedance match to the feed line
