[BC] Freq agile AM transmitters

[Jim Tonne]

Willie:  How are you going to make a "frequency-agile"
output harmonic filter?   The kind where you "just set
the cutoff with a thumbwheel switch?"

Making an oscillator move to a particular frequency is
a piece of cake.  Assuming the transmitter itself has
some harmonic content then an output lowpass or
bandpass will also be needed.  I am not sure that 
would be a piece of cake.
