Traditionally, the start of the AM dial has always been noisy in the day; thus, 600 and others like it are pure nighttime DXing here in NE PA.
On a table radio Zenith during my first nights as a Skook, WCAO Baltimore was there, fuzzy and faint and directional and religious for quite a while now. With that SOUTHEAST signal they once finished in the Top Ten 12+ ratings in Salisbury-Ocean City MD, 85 miles away across Chesapeake Bay!
Three months' later one night, a steady WICC from Bridgeport CT was there all alone*.
CMKA (?) R. Rebelde was another catch one eve,Jan '94.
The WBOB DX test showed up on 5-14-'22. I studied for that one; piece of cake. GE SR 2.
Same radio, barefoot, Jan '23, for an early pre-SRS half-hour of Country from C-KAT from Ontario; good tape IDs.
* In their Top 40 days, WCAO was heard ONCE in Queens; a real female canine what with WICC being so close to 'home'.

WICC's meager 1000 watts got OUT! With that Long Island Sound water-path and that reproachless dial spot they were darn-near a local on transistors, car radios and the shabbiest of clock radios by us. Feel free to drag that purple coverage contour down on that map to drape over the 'r' in the word 'New York'
