From where I live(Scr-W/B region of NEPA), our situation here is the worst. There are a bunch of translators that cover up some of the Philly and Lehigh Valley frequencies, like 92.5(relaying Gem 104 classic hits), 93.3(relays Word FM network), 96.1(ESPN 630/1240), 98.9(relays a religious station off the AM band), 100.3(relays a local religious station on 88.1), 100.7(relays Fox Sports over on AM freqs 1340/1400), 104.5(relays Gem 104 WGMF out of Scranton), 106.1(relays WRTI). So far, the only frequencies I can pay attention to when there is a tropo opening are 97.5 and 105.3. As for our 92.5 translator, it comes pretty well outside of W-B, including Hazleton and parts of the Poconos, I can even still hear them when driving down the PA turnpike heading towards the Lehighton/Stroudsburg interchange where it usually interferes with WXTU. That's because they are the only one that runs on 250 watts. Both 96.1 and 100.7 are only heard within the city of Wilkes-Barre and surrounding areas, but once you enter the PA turnpike, they were replaced by both Cat Country and WLEV, respectively.
Years ago, I can pull in some Philly signals from my location in the valley cities of Luzerne County, now it seems impossible because of all the translators.
So, it seems like the addition of translators is starting to get more common. Perhaps, maybe Philly could add theirs that will cover up some of the shore stations..
