I tried it with an older version, the VM-5.  It didn't radically affect the 
sound of the rig over the air, but with the DC thru the winding, it talked 
back like a speaker in the transmitter cabinet.  I couldn't crack up the 
audio without accoustical feedback.  With the  reactor, the VM-5 was quiet 
as a mouse, and the waveform at low audio frequencies (< 100~) looked more 
symmetrical on the scope.  I haven't run DC through a modulation transformer 
secondary since about 1963.
