Philly Frequencies

93.3 WMMR used to reach beautifully into Maryland but is now garbled by 93.3 WFLS(?) from Fredericksburg,VA. 93.1 WPOC also bumps MMR. WXCY 103.7 Havre de Grace rides over more than just 103.7 Jersey...it affects 103.1 Grasonville/Annapolis and used to scramble 103.9 WDRE Jenkintown.

WJBR is not short spaced with WUSL. Nor is their any scenario in which that would or could occur.

Class-B to a class-B, the FCC says you need 45 miles between one station and a third adjacent (98.9 + 0.6=99.5). Unless WJBR is an early 60s station, in which case the laws of physics magically don't apply.

You have class B 99.5 in NYC and class B 99.1 in Zarepath. What's the FCC ruling on that? ???

The existing FCC FM rules have only existed since 1964. The initial post-WWII rules allowed for second-adjacents. Short-spacings like this one, that already existed when the current rules were written, are allowed to continue.

This is a fun area to be in if you want to study short-spacings:

96.9 WFPG and 97.3 WENJ - two non-directional 50kw FMs that are about 19 miles apart.

96.1 WCTO and 96.1 WSOX - two 50kw FMs on the same frequency, only about 80 miles apart.

105.7/York and 105.7/Baltimore - two 50kw FMs on the same frequency, less then 50 miles apart.

WAWZ and WBAI are too close under today's standards, WLEV and WZXL are too close, WPRB and WKTU are way too close, etc.
 
You also have many pirates short spaced to Class B's in NYC (and also short spaced to other pirates). For example, there's a pirate on 105.3 in the Bronx, just a few miles from Power 105.1. There are multiple pirates on 99.9 in Brooklyn itself, so there are very strong signals interfering with each other.

Speaking of Philly Frequencies. Should Phily have 94.9 FM? Also, should 99.5 WJBR from Wilmington DE move to Attenna Farm in Roxboro?

Also, 97.5 WPEN should it be on 97.3 FM?
103.9 WPPZ should it be on 103.7 FM?
and 107.9 WRNB should it be on 107.7 FM?

There is already WENJ-FM on 97.3, and WXCY, WMGM-FM and WNNJ all on 103.7

How far apart is WMJC in Smithtown, NY and WYBC in New Haven? Both being on 94.3

Having grown up in that part of Long Island, I can tell you that the 94.3 signal in Smithtown goes nowhere. It doesn't have nearly the same reach as the other Long Island signals on 92.7, 97.5, 98.3, 102.3, 103.1, 106.1, etc.

When I lived in East Brunswick, NJ, 99.1 FM was basically just a bit to the west. 99.1 and 99.5 were both listenable in the area. Strangely, on my Sony clock radio, the FM dial is spaced .1, e.g. 92.3, 92.4 etc. WBAI at 99.5 actually came in on that radio at 99.6, probably due to 99.1 being just to the west. :)
 
How far is the religious station on 94.5 from WPST (really in Bucks County) that keeps me from getting WPST in Chester County?

50,000 watt WDAC in Lancaster does beat up WPST quite badly once you work your way west.....Other stations like 94.3 WJLK & 94.7 WFME also hurt their signal in New Jersey.
 
Some other short spacings:

97.1 W246?? and 97.1 W246?? One does reach fm and the other is wrdv
95.1 W236AF, WAYV, WZZO
106.5 baltimore and 106.7 washington d.c.
92.1 vineland and 91.9 barnegat ( power might be too low for both stations)
100.7 WLEV/WZXL/W264?? Mt Holly
91.7 WKDU/WLBS/WBMR
94.7 WDSD/WDAC?
97.5 WPEN and WENJ (only 20 miles from center point)
98.3 and 98.7 down the shore ( cape may county )

106.5 baltimore and 106.7 washington d.c.

106.7 WJFK-FM is actually licensed to Manassas, VA and transmits from Merrifield, VA. Both 106.5 and 106.7 are owned by CBS. Because of the existence of 106.5, the signal for 106.7 is pretty poor toward the northeast of the DC market. Which is why, when the Washington Nationals selected 106.7 to be their flagship station, they also retained 1500 AM in Washington as an affiliate.

Other short spacings in that market:
98.7 Washington
99.1 Annapolis
99.5 Washington

These are second adjacent rather than first, but they still cause problems on analog-tuned radios.

I'm not sure when WPST went on the air, but I believe WDAC has been on the air, as a religious station, since the last 1940's. Actually, I wish WPST wasn't there, because WPST's signal cuts out WDAC's signal in the Wilmington area. You can get it pretty well in the Newark area, but the closer you get to Wilmington then WPST cuts in.
 
There are three class B FMs sharing 99.5 on the I-95 corridor, NYC, Wilmington DE, and DC. Wilmington is closer to DC than NY. I think Wilmington's 99.5 has more power than NY and DC. Does Wilmington's 99.5 interfere with DC or NYC's counterpart? ???
 
IIRC just from living there, the 99.5 in DC is one of the more powerful signals in that market. I imagine it would be even more powerful if there wasn't a 99.1 in Annapolis.

That 99.5 signal is powerful enough that I think it singlehandedly won the CHR war for that station against a weaker opponent with a fair amount of heritage in Z104 on 104.1.

DC is a weird market. They have transmitters and COLs all over the market, as opposed to Philly and NYC where most (I know not all) stations are licensed to the big city. By my count, there are only 9 commercial FM stations licensed to Washington, D.C.

WDAC might be a full B, but they are not 50,000 watts. There are 19,000.

19kw @ 247m is the same as 50kw @ 150m. WDAC is a full 50kw class-B.

WPST actually went on the air on 97.5 not 94.5. I wish WDAC wasn't there and WPST was still on 97.5.
