FM 87.9

 

Is there any way to reach FM 87.9?

The lowest seems to be 88.1.

Thanks.

it's outside the FM Broadcast band

In a word - NO. It's not a broadcast radio frequency.

FM 87.9 mHz

It is funny you should mention that frequency. That is what I use on my farm to broadcast to other radios around the farm. (Not GPS of course). I suppose you could by an after market device. Some of those offer 87.9 mHz as a choice. In fact, I bought a $12 one for my wife at Wal-Mart a few weeks ago that is battery powered for her Slacker Radio. She said that it works great.

As a side note, a friend of mine who works in the broadcast field, TV not radio, tells me that there are three FCC licensed stations in the US on 87.9 mHz. I have not been able to confirm this, however.

The FCC records turn up

The FCC records turn up three stations licensed and one with an application on 87.9MHz:

KSFH 87.9 MHz MOUNTAIN VIEW CA ST. FRANCIS HIGH SCHOOL OF MOUNTAIN VIEW
WJCF-FM 87.9 MHz MORRISTOWN IN INDIANA COMMUNITY RADIO CORP.
K200AA 87.9 MHz SUN VALLEY NV CALVARY CHAPEL OF TWIN FALLS, INC.
WA2XNX 87.9 MHz BRAZOS TX FEDERAL SIGNAL CORPORATION

Transmitters that work below 88 Mhz aren't legal in the US

Frequencies below 88 Mhz are used by Television channel 2... The stations listed above that are authorized to operate below 88 Mhz are special circumstance, low power applications (In house school programing etc).

FWIW, unlicensed transmitters are authorized under the Federal Communication Commission Part 15 rules. These rules spell out the power levels and frequencies that an unlicensed transmitter can use.

FM band transmitters can only be used between 88 and 108 Mhz. See page 97 Section 15.239 of the FCC's Part 15 rules:

http://www.fcc.gov/oet/info/rules/part15/PART15_07-10-08.pdf

You CAN buy transmitters that operate outside these bands... (It's next to impossible to inspect every electronic item that comes from Hong Kong smile ) But as per the FCC regs above, they are illegal....

Scosche FMT4R

Scosche FMT4R

These are usually in the Wal-Mart Automotive section NOT by TVs, DVD players, etc.

.

Apparently, it is available from Wal-Mart but from what I gather reading around a bit, this thing is likely not legal...it's also not shown nor referenced anywhere on the Scosche website that I could find.

A quote from a comment in the linked topic below:

"On the other paw, it's Wal-Mart. They can get away with anything."

It's out-of-stock everywhere -- legal or not.

Thanks.

Depends on how bad you want to do it and how much money you want to spend. I have a handheld AOR scanner that will pick up anything from .1 meg to 1.3 gig, AM, FM, or wide band FM. I use it mostly at airshows to listen to the pilots talk back and forth.

I think Cyberian75 wants to transmit on 87.9, though, not receive the signals as your scanner will do.

Older Car Radios Can Tune to 87.7

On the older car radios, the ones that have a dial, you can tune down to 87.7. Both of my cars (2003 and 2005) have them. In Fort Worth, I can pick up a Spanish-speaking station on 87.7. I usually use 87.9 to listen to my TomTom GO 930, but around Fort Worth and other large cities, it is either in use, or being bleed over by another station.

Well, THAT really clears up the subject.......NOT.

In one message, you say they are flat illegal but then you also say they might be legal if the power is low enough.....or if you get a special use license.

What ???

I think you misread his post(s). In one case he is talking about rebroadcasting unit (like the Walmart) product, and in the other case he's talking about licensed radio stations.

Nuvi 660 -- and not upgrading it or maps until Garmin fixes long-standing bugs/problems, and get maps to where they are much more current, AND corrected on a more timely basis when advised of mistakes.

Actually, the frequencies immediately below 88 MHz are allocated to analog channel 6, Channel 2 is at 54-60 MHz.

87.9 is a bona fide (and numbered) FM broadcast channel (200). However because it overlaps with the top of channel 6 it is allocated sparingly, as has been noted above.

My vehicle has that, too, but it doesn't go below 88.1. Oh, well.

Sorry, I didn't see the word transmit in his post, all I saw was "reach FM 87.9".
