That's funny cause at night it's an iffy catch in the Pgh area. :
Caught it at least ten times, KDKA. Comparable to KYW it seems.

Several months ago, I ran some L-R contours for selected FMs in markets of interest to me. A handful of those from Pittsburgh, Chicago, Dallas-Ft.Worth and Nashville are here:
http://www.onairusa.com/fm/
It takes a good while for each one to load, so be patient. I used the same code that generates the television maps at Trip Ericson's RabbitEars, adjusting only the receiver height. The facility data was scraped from FCC records. The terrain models came from the Shuttle Radar Topography Mission data.
As they say on Radio-Locator, consider it for "entertainment purposes" only. But since the calculations are the same for the facilities, they do show relative comparisons.
I just now updated the Pittsburgh area Longley-Rice FM coverage maps to add WDVE, WWSW and WPKV. It takes about an hour for each map to get generated.
The contrast between WPKV's 3700 watts at 807' HAAT and that of WWSW's 50,000 watts at 810' HAAT is interesting to see.
Of course as hypwr and I used to say, these L-R maps are all just for the Armstrong "experimental" band. It'll probably never catch on since the really good stations are all on the "standard" wavelengths like that Fineview facility of WWSW at 1500.

Any chance of adding Philly?
RadioPhillyFan said:Any chance of adding Philly?
It takes a really long time to run these and there are several hoops I have to jump through to configure the QTH and LRP input files. But, being a kind soul, I can do a small sample for Philadelphia. Give me three call letters for that market and I'll crank them out. Since most are in Roxborough, there won't be much deviation -- so pick the three of greatest interest.
Because I have ties with the other markets, I generated the L-R maps primarily out of personal interest. Aside from a long-ago high school friend who moved to Berwyn, I don't follow media happenings over on the eastern side of the state. But I'll do three from there for you.
If I could make some suggestions for interesting comparisons, Bob... you're quite right that any of the Roxborough Bs will be about the same as any of the others. WOGL is probably as good as any others.
There are, of course, three commercial Bs in the market that aren't at Roxborough - WMMR 93.3 is on One Liberty in Center City and WISX 106.1 and WPEN-FM 97.5 are up at Wyndmoor.
The other sort-of-interesting comparison might be the Roxborough Bs against the Roxborough A (103.9, whichever calls it's running this week) or the One Liberty B (WMMR) against the One Liberty A (107.9, whichever calls it's running this week).
And then there's WKDN...
(These maps are great, by the way, Bob...thanks for running them!)

WMMR
WRDW
WPEN-FM
These three, thank you so much! If ever need be, the forth one would be WPPZ - that station travels far for a Class A.
Also Scott, PST could be considered a "Philadelphia Signal" - as they call themselves so incredibly often.

OK, between RadioPhillyFan and Scott, consider my arm twisted. I am always in Scott's debt because of the information he's provided over the years about so many things regarding facilities.
So, I decided to go full bore and run 7 from Philly:
input/wmmr.qth
input/wppz.qth
input/wogl.qth
input/wisx.qth
input/wrdw.qth
input/wkdn.qth
input/wpen.qth
This will take quite a while, so check back much later in the day. I also may have some trouble with the SRTM data for the coastal regions of Jersey but the inland Longley-Rice FM maps ought to be OK. And I was curious about WPPZ myself since I recall it during the WIBF era, thinking it odd that Philadelphia had a class A at the tower farm.

Why do I have a funny feeling that some Boston and Rochester L-R maps are going to be requested from someone? ;D

Yes, thank you!
RadioPhillyFan said:Yes, thank you!
You're welcome! The first of the Philadelphia L-R maps are just now starting to appear.
For general interest of we tower geeks, select the Satellite View and then zoom in as much as possible. It'll then take you to the transmitter location. I still haven't adjusted my thinking to fully grasp that WLTJ (ex-WPNT and KDKA-FM) relocated to Ivory Avenue from its longtime site off Montana Avenue. In any case, it's a good way to judge the accuracy of the FCC data used to generate the maps.
I ran a traceroute on some of the visitors to the website. Who could that Comcast user be from Bethel Park? An old radio colleague maybe?

Sorry, Thats my fault. I moved WLTJ's transmitters in the middle of the night and I didn't tell anybody except the FCC and WPGH, and I didn't tell George J at KDKA until the next day when the transmitter building was cleaned out and I handed him the keys. very long story here
well, today he would say Booo!
