[Milsurplus] Re 348 antenna circuit

[Hue Miller]

You know, i have never seen any article on changing the 348 B.C. receiver 
antenna input to low impedance.
"One" could relatively harmlessly, I think, put a small antenna winding over 
the input coil.
It kinda amazes me that it works as well as it does, with a wide range of 
antennas, including modern ones.
But a low-Z input would be an improvement, no ?
