In order to radiate any power at 137 kHz you need a very long antenna
and LOTS of antenna current; I can't imagine your coil tuning with the
capacitance of a long antenna attached. The "big boys" are doing it
that way, and going to great lengths to build high Q loading coils.
There have been at least a couple of articles in QST that you might want
to look at. I'm afraid your TC wouldn't do very much, but the primary
driver might work with a suitable antenna and coupled loading coil.
One added problem would probably be frequency stability. The "across
the ocean" communication which has been received involved using receiver
bandwidths of less than 1 Hz, and if your transmitter had more frequency
drift or incidental FM than that no one would be able to receive it.
