WKDN Changing From Non-Comm Back to Commercial?

[w9wi]

1210 is the worst of the non-directional Class A channels, as far as local area groundwave coverage is concerned. (among U.S. stations) (the directional As between 1500-1560 are worse)

Simply because it's the highest frequency. Groundwave drops off (dramatically) with increasing frequency.

At the same time, skywave -- "DX" -- improves with increasing frequency.

So I'm not particularly surprised to hear this station doing better in St. Louis than in Atlantic City!

(though my observation has been that it really doesn't do very well here in the Nashville area...)

I think ground conductivity is even worse than that here in the Carolinas.
I'm in between Greenville SC & Charlotte NC and could barely hear just 3 AM stations during the day
(WZZQ, WORD, WBT), the rest of the dial is blank or very weak signals.
Other stations should come in much clearer (like WOLI-AM or WSPG or WWOL) but it only looks good on paper.

Comparing the groundwave 1210 WPHT to 1110 WBT, I'd have to say it looks a little worse for 1110 WBT.
At night WBT is directional North-South and I've heard 1110 in Port St Lucie FL & Concord NH & across NJ,
but just 40 miles west of Charlotte where I am it's hard to get it at night, and just barely ok in the daytime.

And when I did live in Toms River NJ a few years ago, 1210 came in great, but I was barely able to pull in 610 or 1060.
