I _know_ I'm going to regret this, but when I was building 6AG7-807 rigs,
and trying to get a Mark II make more AM than FM, I found chirp to be a
function of the oscillator circuit, not so much the crystal.  Of course, I
probably had "good" JAN crystals to use perhaps hand-trimmed by the
scouring powder and glass method....  I'd love to hear of some source
material for this.
I do know that the intelligence/ECM folks were often clutching at the
smallest of advantages, so it wouldn't have taken much for them to try this
(Lets not restart the "LO radiation" thread again!).
