All the power levels are controlled by the contoller in the transmitter which is programmed for the
three power levels.
Three power levels? We know about 5 gallons, and about 52 watts, but what's
the third? Are you referring to a PSRA, which now is not needed until September?
And what exactly is the PSRA power? The data on the FCC site is really hinky.
BTW, the power drop tonight ("7:15") was at 7:14:55 PM.
