The 630-meter limit is 5 W EIRP, with the exception the question sets aside: stations in Alaska within 800 kilometers of the Russian Federation are held to 1 W EIRP. The 1 W EIRP figure alone is the 2200-meter limit, and the flat 50 W and 100 W PEP values are not in the rule at all, which caps transmitter power on this band at 500 W PEP.
