[IRCA] grounds for antennas

["Powell E. Way III W4OPW" <w4opw@xxxxxxxxx>]

First, from the FCC site, heres the US conductivity...

http://www.fcc.gov/mb/audio/m3/index.html

In actuality, conductivity in most places is much
lower than rated.

When you do a ground for your radio, it's best to go
as deep as you can. 

On some non DA South Carolina stations close to where
the conductivity goes from 4 to a 2 the day non DA
looks wierd. Look at the WBT daytime coverage map. The
larger area is in a 4 the smaller a 2 or less.
