Re: [IRCA] Recent DXpedition to Grayland, WA & Florence, OR



Hi,
Are these soil conductivity maps for Canada available online? If not, where might I be able to get them?

I've seen similar maps for Canada. The east side of the Rockies in Alberta
is supposed to be superb for MW DX, and it has been proposed that this is
due to the excellent ground conductivity.  Interesting thread,
indeed!........Walt

An important aspect of losing signal when going away from the shore is the ground conductivity in that area. That makes a significant coverage change for any identical station by frequency, power and antenna. Local stations
like 1230, etc., cover far better in the middle of the US than in places
like New England. The FCC has a PDF map that can be downloaded to show the
ground conductivity in the US.  Should be accurate for Canada near the
border as well.
