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....

Warmest regards,
John

Marbles can be used in models with excellent results! However, if forced
to keep using all of mine up... I may end up at a disadvantage... I seem
to have misplaced some!!!
