There are cases where the Q of the tuner and antenna combination
restricted the way the transmission can be modulated.

In aviation, there are non-directional beacons (NDB) working
in the MF range. Due to obvious mechanical restrictions, the
vertical antennas are very short compared to the wavelength
(70 ft compared to 4000 ft). We had to limit the frequency
of the AM modulated identifier Morse code from the standard
1050 Hz to 400 Hz to pass the bandwidth of the antenna system.

And yes, there was some power, typically 500W into the antenna
and a couple of W into the air.
