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.
