It's not a modification, its just a trick. I can't remember the deatiils 
but you simply hook your antenna to one of the test points in the RF deck 
(or maybe to the grid of one of the tubes) and bypass the RF amplifier 
stage.. You run the radio in the 0 Mc band and just tune down below the 
normal 500 kc point of deafness.

Take a test prod and experiment.  It's a no-cut, no -solder, reversible "mod".

VLF converters are a whole different matter.
