So you're saying that there's no info because it's far too simple - so why
bother to write it up in a text or app note?

Surely there is some small amount of "finesse" involved - whether it be in
the implementation of the modulation transformer or in trying to get the
optimum modulation levels in general. Nobody has covered this in a text?

I'm sure I could come up with some brute-force approach in doing the
high-level modulation using a kludge transformer (the "grenade" guys
are using simple line level transformers run "backwards")...

Either there's a more "scientific" approach to this or, as you suggest,
it's always done empirically??? Just wondering......

Just run the output of any audio source of ~5 watts into a "modulation
transformer" and have the B+ to the transmitter pass through its
secondary...

You can also construct an audio amplifier whose output power final
"modulates" (perhaps the B+ from the audio amps final transistor/tube) the
B+ to the xmitter... etc... ssb is by nature 2X-plus more efficient...
fm
supports greater sound quality...

I think detail about it is skipped simply because it is so easy to
affect....
