I've been saying this for years here and elsewhere-- but whenever someone else crystallizes it so well (as did Observer2 in the lead-off post here)-- it gives me personal validation and makes me feel all warm and fuzzy.
For a 50,000-watt non-D, 1210's signal sucks. It has for some time, at least going back to the last decade or so of WCAU. Why message board- and radio geeks drool over the supposed "value" of moving, say, WIP or KYW to this lateral (if not, inferior) facility boggles the mind.
In many parts of Montgomery and Chester counties, 1210 is but a faint whisper in the shadow of a "King of Prussia" daytimer on 1180.
But the bigger problem isn't 1210, or it's ground system. It's the nature of AM radio, and the fact that it's long been past time to sunset this 100+ year-old technology.
In a similar-but-unrelated story, the 106.9 signal is terrible too. Getting sick of people trying to put it in a league with the ones from Rox. You people posting from other markets may look at those freebie Radio-Locator maps and think, "CBS will put KYW on 106.9." (Even though there's no solid information the company will ever even *have* this station.) What you don't know is that the signal has a severe penetration problem, transmitting from an average-sized tower on the eastern bank of the Delaware. It's not ready for prime-time.
I too would love to hear the Phillies on FM. This needs to happen. Everyone wants it to happen, including the Phillies. But remove the Phillies from WPHT, and it's suddenly revealed (to those who don't already get the breakdowns) just how weak that Talk station really is (and I'm not just talking about signal). Someone earlier put it well-- without the Phillies "1210" won't be just the station's frequency-- but also its cume.
