KFAQ 1170 is audibly strong in Central Ohio today, for no reason I
can see, at local noon more or less.

If you null away WWVA 1170 Wheeling WV, it's almost listenable.

800 miles.

Both WWVA (100 miles) and KFAQ are non-directional 50kw.

Winter month noon enhanced groundwave or "daytime skywave" is not uncommon
at those distances. Use of phased arrays makes it more possible.

In the early 60's, when Conelrad had all US stations off the air for 30
minutes on several occasions, I heard, in Ohio, Canadian operations as
far
away as Manitoba on the empty channels. I have also hard clear frequencies
such as 4VEH-1035 in Cleveland from Cap Hatien, Haiti at noon.

In the same location, 540 often revealed either KWMT or Watrous before
Milwaukee went on the air, nulling the SW PA station.

Such reception usually, but not always, followed a period of ionespheric
disturbances, like auroral conditions.



While not on the scale of these reception reports, I had an experience with
some very high level long distance ground wave reception from both
directions:

In 1972, I was living in Astoria, OR. For several days in a row, I was able
to listen on my car radio to KFXD 580, Nampa (Boise), ID as well as I could
normally receive a station only 21 miles away.. and this all day long. KFXD
was at the time only a 5KW station.

In 1988, during a snowstorm, I was east of Lewiston, ID (small town called
Kamiah). I tuned around on my Superadio II, looking for some DX (Spokane was
usually not a problem on AM from there). In addition to the usual lineup,
another 5KW station, KGW in Portland, OR was booming in like a local! I
listened for hours, even got on the phone to my friends back home (Portland
is my home town) and let them listen to how well KGW was coming in over 400
air miles away (normally there had been no sign of any AM radio from west of
the Tri-Cities)
