You're describing tropospheric ducting, AKA 'skip'. Ionized layers of the atmosphere can act as reflective wave guides. If the all of the right circumstance occurs simultaneously, you can experience the phenomenon you describe. As the weather changes and as the sun rises and sets, you'll see the ducting effect change.

I don't doubt your skill as an antenna builder, but without the aid of charged molecules in the atmosphere, your antenna is not going to 'see' Pittsburgh signals.


FWIW: http://www.rabbitears.info indicates KDKA has no translators.
