Wouldn't an elevated ground system give WNSH better results? Is it just
an Old Wife's Tale that eight elevated ground wires, a counterpoise if
you will, may come close to the 120-wire buried ground at a good site?
Of course the granite soil beyond the ground system will still result in
lower efficiency at WNSH, but wouldn't that be true at Marblehead as
well - until one reached the salt water?
BTW, the FCC is again updating CDBS data and Larry uploaded new data for
AMSTNS and TVFMSTNS yesterday. CDBS data had been stuck on October 11
