You Say "Skizzum", I Say "Sizz-um"...

0.1 mS/m also occurs in Central New Hampshire and in the coast range of
My 1Kw on 820 in Waldport, Oregon is headed for the noise at 20 miles, but
my 1kW on 1230 in eastern Oregon (Burns) is still very listenable at 75
miles, 1230 in Toledo, OR., near the coast, like Waldport is almost in the
noise within site of the tower! In both cases real conductivity is far
different than shown on the FCC map. A lot of <0.5 mS/m in western
Washington state, too. I've driven many miles and made many measurements!

Now that it appears likely that at any time between sunrise and sunset
(7:00 am thru
4:15 in December), WQOM will be at maximum power, has anybody out there
who lives in Boston, Brookline, Cambridge or Somerville, or drives around
communities during those hours, tried to tune in to WQOM? (Or, Medford,
home of WILD-AM, although this station is weaker than WBZ-AM and no longer
emits IBOC hash).
