RE:  pulsed noise:  Only if the pulses are spaced far enough apart to 
cause the screen potential to decay to near zero volts between pulses.
RE:  speech modulation:  I have listened with stereo headphones using two 
double-filter receivers.  The total IMD in the window above or below the 
DAF amps. was no better than 23db down.  However, this is perfectly legal 
as long as the rotten splatter does not go outside of the ham band.

V8.
