If I may add to your fine list there, Kev .....
In the 70's, around there, a 5000-watt daytime directional signed on 1460 from their city-of-license Mount Holly NJ.
The calls were WJJZ. The new facility broadcast from four towers from some sand-spit in the Delaware River.
WOW, were they one tough' male offspring of a female canine' to hear up on Queens near JFK.
So I couldn't tell you what their format was. All I heard, in a super-surreal null of semi-local WVOX 1460, was an ad for the Burlington County Times, or some newspaper with a similar name.

We DXed from near the 'r' in New York.
I'm fairly certain that the new 1460 / WIFI / Mount Holly broadcasts from a different tower site than originally.
Now this 1460 station is known as 'WIFI' -- taken after a previous Philly station (and a good one) on 92.5. In fact, oddly, I once casually HEARD this WIFI 1460 one sunrise / breakfast at a paint job in nearby St. Clair. They do send a bit of a signal tongue our way, north of Pottsville on the map.
Thanks for the history, Kev !
