  1. 1000 watts PEP output
  2. 200 watts PEP output ✔
  3. 1500 watts PEP output

Why: The whole 30 meter band, 10.10 to 10.15 MHz, is capped at 200 watts PEP. Most other HF bands allow up to 1,500 watts PEP.

Huh, didn't know that: The 200 watt cap on 30 meters applies to every station, whatever the license class.
