Another Station Likely to Leave the Air Soon

According to some markets, quite a few.

WPOZ in Orlando is at 88.3 and WUSF is 89.7 and WCIE 91.5, both in Tampa. They are among the top stations.

Those are just three I can think of locally.

The more affluent and educated the market, the greater audience share noncomms usually command. In Lebanon-Hanover-White River Jct. VT/NH, where the economy is dominated by an Ivy League college and a major regional hospital, Vermont Public Radio's news/talk WVPR was second at 8.3 in the most recent book, with VPR's all-classical WNCH tied third for third at 4.5 with country WXXK. New Hampshire Public Radio claimed another 1.9 with news/talk WEVH.
 
Could WNYZ-LP in New York be returning to the air? An article in RadioInsight states that the F.C.C. has granted several more stations on 87.7 an STA to keep operating, pending a upgrade to a digital TV/analog audio signal. The article mentions that WNYZ-LP has applied for such an authorization.

Some of these stations may eventually be able to move to 87.9 providing there are no adjacent channel issues. Here in California we already have a 10 watt class D station on the freq in Mountain View. This looks like it might be the first US FM station on that freq. Canada has already officially allocated 87.9 to FM because they no longer have any channel 6 TV stations.
 
The station is KSFH at St Francis High School and probably operates only specific hours. The minimum broadcast hours for any station is supposed to be 20 hours per week, however this probably waived for Class D 10 watt educational stations.
 
KSFH is a grandfathered 10-watt Class D educational station. The FCC isn't allowing any more of those to be built, regardless of what frequency they're on. 87.9 was specifically reserved for these stations, which means there won't be any more legally licensed stations on 87.9 unless the FCC changes their rules.
 
From my understanding...

All educational non-coms are to meet a minimum of 36 hours a week during the weeks the educational institution is in session. I doubt the FCC strictly applies that to 10 watt Class D stations.

87.9 can be utilized only when all other frequencies are unavailable as long as proper spacing is afforded and TV channel 6 is not an issue. This may be the only 87.9 remaining although I think there might be another. I would suspect 87.9 would only be allowed if an existing Class D was forced to change frequencies due to an upgrade of an existing station. As confusing as that sounds, Class D is secondary. A full power can change tower sites or increase power. If that causes the Class D to be 'interfering', the Class D is obligated to change frequencies. Should 87.9 work and no other frequencies would, I would think the FCC would license the move. Other stations such as the 10 watt St. Marks School station in Dallas was forced from the airwaves due to such moves. I think that was about 3 decades ago.

It is correct any 10 watt station existing today is 'grandfathered'. No new 10 watt FMs will be licensed (except higher classed stations with higher height above average terrain reduces the output power, say, from 100 to 10 watts.

i thought that years ago the FCC was intent on eliminating Class D stations, by converting them to Class A and granting the minimum Class A power of 100 watts.

That's correct:

Prior to 1978, the FCC had a Class D FM broadcast service that was available for noncommercial educational broadcasters. The Class D service was used primarily by high schools and colleges for student operated radio stations. At that time, Class D stations were allowed to operate 10 watts from the transmitter (TPO). They were allowed to use a gain antenna to increase their effective radiated power (ERP) for slightly wider coverage.

The large broadcast stations considered the Class D stations to be a hinderance to the growth of the larger stations as well as the cause of interference. As a result, the FCC would make changes to the Class D service including changing the power limit to 99 watts ERP (based on 30 meters height above average terrain). They also made the stations secondary status thus meaning that they could be displaced by full power stations. As a result, Class D stations in more urban areas would be forced to occasionally change channels if they want to stay on the air. There are currently about 50 Class D FM stations in the lower-48.
 
That's correct:

little known fact.. new class D fm educational stations can still be licensed in alaska.. and you dont need to wait for a filing window, you can file for the license at any time.

Correct, in fact had I posted the complete page (not just the two paragraphs), it would have said that and explained how to do it.

This is exactly how ksko grew.. from one AM, now deleted, to more than half a dozen class D fm's. including one that just signed on a few weeks ago
 
Our ever-popular 88.5 KCSN Northridge went on the air originally as KEDC on 88.5 as a 10 watt class D station in the early 1960s. Even so, it could still be heard through out the SFV with a good rooftop FM antenna. Many folks wanted to hear the unique programming.
 
I doubt most people even know that the FM band is reserved for NCE stations below 92 MHz. If they're going to do a band scan they'll scan the whole band and pick the station that's playing the content they want to hear regardless of frequency.

The problem with the Franken FMs was that some radios don't even tune that low, and most of the remaining modern, digitally tuned radios sounded terrible on the 87.7 stations. That's because those stations were really transmitting on 87.75, halfway in between 87.7 and 87.8. Every one of my radios sounded staticky and distorted on the Franken station because it was impossible to tune into the exact frequency. On one of my Sangean radios, WNYZ actually sounded a little better on 87.8 but it was still too distorted to tolerate.
Before I had Bluetooth audio in my current vehicle, I used a FM transmitter in my old one. Where I live, 87.7 was a safe bet to broadcast over, as in my area there's nothing on 87.7. However, it always sounded horrible, and in tests, I could get my phone's playlist to block out some strong FM signals. So, could it be that it's 87.75 or that the 87.7 signal is just weak in general?

FCC Part 15 licensed FM modulators are only allowed to use exactly 88.0 to 108.0 MHz. If the modulator you were using allowed you to transmit on 87.7 or 87.9 MHz, then it was not built to FCC specifications and may not have been a very good design anyway.

It is good, but I have to admit that I bought it from a Canadian seller on Amazon, strictly because I couldn't protect the four frequency range starting at 88.1, where I live. We are jammed with translators and stations that are close in frequency. Needed it to be used on 87.9, as the closest station is still on 88.1, but is MIT's station and has a weak signal where I live.

In fact, I think it may be a bit stronger than the FCC limit in power. In a test while driving through my neighborhood, I was able to block out WXKS-FM Boston in my wife's car (driving in front of me), with me playing Irving Aaronson's "Let's Misbehave." She got out of the car complaining how some weird old song started playing in the middle of what her and my kids were listening to. Once I knew the range it had, I was glad to have something that worked perfect and could be used on 87.9.

Either way, it is now obsolete for my use, as I now have Bluetooth enabled radio in my current vehicle. I haven't needed the transmitter for two years now. My wife's minivan that we've owned for eight years is also Bluetooth enabled. I needed the translator as I was driving an old Honda CR-V for years with just a standard FM-AM with CD and Casette capabilities; and the cassette adapters worked until the cassette player broke in the car.

WNYZ-LP 87.7, New York Radio Korea, has returned to the air. They're the station that shut down in July, due to requirements that all low power TV broadcasts needed to use digital signals.
I don't know the specifics, but it appears that the F.C.C. has approved their application to broadcast digital TV, and separate analog audio. That would make it possible to resume broadcasting as a sort of semi-radio station.
Does anyone know what they are broadcasting on the video portion of their signal?
