Bear, et al:
?
Here is something I found on the Public Seismic Network archives.
?
"New article in the May '96 issue of Scientific American (pg 98) describes
construction of VLF antenna. Their plans use a 24" piece of rebar for
the core of the coil. Anyone have a good source for Mu-metal cores in the
2' range???"
?
Guess I will?look up the SA archives & see what is there.
