For those who are interested I have been able to amplitude modulate
the output from one of those 4 terminal crystal oscillators.  I
hooked the supply voltage in series with an ordinary telephone and
then I could press the touch tone buttons or speak into the mike
and this signal could be heard on a nearby reciever.  My supply
voltage across both xtal osc. and phone was 12 volts.  The phone had
6.5 volts and the xtal osc had 5.5 volts.  It seems like a new form of
QRP has been born.

Now, if I could just find some that allow me to tweek the frequency!
