The biggest AM station was 1 Million Watts (1 megawatt).

There are a handful of 2 megawatt AMs - at least one in Saudi Arabia.
(where I'd imagine the ground conductivity is horrendous so it still
doesn't "get out" all that wellgrin)

UHF TV stations are licensed up to about 3 Megawatts, but this is "beamed" by
concentrating the signal along the horizon. The actual transmitter is 100 KW or
so.

5 megawatts is the maximum legal power for analog TV in the U.S.. I'm
aware of transmitters available up to 220KW output.

That's ERP, though, no?

Here in the Central Valley of Calif- Fresno- All of our TV has been UHF
since the early 60s. The major network stations here run 5 megawatt ERP
from mtn. tops 25mi away. I'm not sure about how height above average
terrian calculates in the equation to determine ERP.

Yipe. To HAAT and ERP, add DFMA[1] as a very important measurement.
