I know the ground transmitters are 10 Kw, but I never found out what power
output a big jet like the 747-400 puts out? Anyone know?

A 747 might be equipped, for example, with Collins HF-220 transceiver, with
a Collins PWR-200 amp. This puts out 100 Watts PEP with an average of 25
watts RF output (for SSB) according the unit spec.
