VLF as in Very Low Frequency?
First Google result was this forum message second was this http://www.cdarc.co.uk/talknotes/VLF-G3XBM.pdf

I might seem like an idiot but remember it takes one to know one.

VLF transmitters and receivers require very long antennas to transmit properly and operating at such frequencies is not a good choice at all unless you happen to be a nuclear powered submarine looking to receive missile launch orders while still submerged.
