My elmer told me that if you put DC source in series with the neon bulb and 
a resistor and set the voltage just below the ignition voltage of the neon, 
it became a more sensitive indicator of RF.  The old guys used "B" 
batteries.  Today one could charge up a decent quality cap and get the same 
result.
