Chasing Low-Power FM Stations

By Jock Elliott, KB2GOM

Male voice, singing: You’re the reason I have bald tires on my car . . .

Female voice, singing: You’re the reason I threw your clothes out in the yard . . .

Male and female voices singing in harmony: You’re the reason our kids are ugly . . .

. . . and that was my introduction to WOOG low-power community radio in Troy, NY.

Holy smokes . . . that’s outrageous . . . and funny, too!

Sometimes, in hindsight, it can be difficult for a writer to determine when and where  story actually began.

With this one, was it when the FCC began licensing low-power community radio stations in 2000? Or was it when I began hosting a Radio Monitoring Net on the local 146.94 repeater (Troy, NY) at 7 pm on Tuesday nights?

For sure, a tipping point was when one of the net participants suggested check out a low-power FM community radio station on 92.7 FM. It’s kind of like western swing, he said.

I did check it out and found it to be a combo of traditional country and what I call “hillbilly jazz.” No announcer between musical selections, and occasional station IDs. At 7 am, I heard the Ralph Nader radio hour. Allegedly it is licensed to the Oakwood Community Center in Troy, NY, but nothing on the air that I have heard suggests that connection. Very curious. Is a place-holder for something else?

It turns out there are hundreds of low-power community radio stations across the United States. They are limited to 100 watts and an antenna height of 30 meters (100 feet). According to the FCC:

To qualify for an LPFM license, you must be:

  • A government or non-profit educational institution, like a public or private school or state or private university
  • A non-profit organization, association or entity with an educational purpose, like a community group, public service or public health organization, disability service provider or faith-based organization
  • A government or non-profit entity providing local public safety or transportation service, like a volunteer fire department, local government or state transportation authority
  • An Indian or Alaska Native tribe, band, nation, pueblo, village or community that will provide non-commercial radio services.

In addition, applicants for LPFM licenses must be based in the community in which they intend to broadcast. An organization is considered community-based if:

  • It is physically headquartered or has a campus within 10 miles of the proposed transmitting antenna
  • Seventy-five percent of its governing board resides within 10 miles of the proposed transmitting antenna
  • It is a non-profit or governmental public safety organization that intends to broadcast within the area of its jurisdiction
  • In the case of a Tribal application, the applicant’s Tribal lands are within the service area of the proposed station.

There is an article about LPFM stations here: https://www.pewresearch.org/short-reads/2016/09/19/number-of-u-s-low-power-fm-radio-stations-has-nearly-doubled-since-2014/ and a listing of the stations here: https://en.wikipedia.org/wiki/Category:Low-power_FM_radio_stations_in_the_United_States

There are several LPFM stations in my area, and chasing them is fun. I found the best success with my Tecsun PL-880 and its long whip antenna. Sometimes the whip works best when held vertically; sometimes, horizontally; sometimes moving the whip horizontally as little as 45 degrees will blank one station and bring up another. The end effect is to look like a drunken sword master while getting into the Better Half’s potted plants, knocking over scanners on the desk, and other encounters with the long whip.

Nevertheless, chasing low power community radio stations is fun, and I can predict, with some authority, that you may encounter programming that you won’t find anywhere else.

Summer FM DX: Drive-by Sporadic E

Many thanks to SWLing Post contributor, TomL, who shares the following guest post:


Summer DX – Sporadic E, FM band

“Sporadic E” DXing is a specialty of some DXers.  I have never dabbled in it being content with mediumwave or shortwave listening.  However, it was truly fun to spontaneously hear this happen while driving on the Interstate highway, Wednesday August 4 around 6pm Central Time.

To quote from an ARRL propagation article:

“As frequency increases still further, signals will eventually pass through the F1 layer to the F2 layer. Because this is the highest reflecting layer, the distance spanned by signals reflecting from it is the greatest. The maximum skip distance for the E layer is about 2000 km. For the F2 layer that increases to about 4000 km—a significant gain.”

I was listening to the local classical music station WNIU in DeKalb, IL which is a good 50 kW transmitter about 10 miles behind me near the Interstate highway.  A different station was breaking through. Eventually, I heard a familiar Christian song “You Make Me Brave” swamp the classical music. I noticed it was a remake of a song made about 10+ years earlier. The two signals fought it out and then I heard the station ID “Spirit FM” and a short humorous segment called “Attitude Adjustment”, then more music.  Finally the local classical music station won out and I thought I would look up the station ID of that contentious station later.

When I googled “90.5 Spirit FM”, it came up with a station in Tampa Bay, FL called WBVM. Cool!  Just to be sure, I went to the station web site and looked up their playlist and this confirms what I heard:

Curious about the transmitter, Radio Locator said it was a 100kW station and gave the Long/Lat coordinates.  I then went to Google Earth and mapped an approximate distance of 977 miles (1572km), give or take 10 miles:

I did not have time to get on the shortwave radio to see if the 10 meter band was busy since I had things to do.  But it is a very nice surprise to hear in my old car radio an FM station almost 1000 miles away. For one thing, Analog radio is still fun.  Secondly, things are busy this summer if you are at the right frequency and time!

Happy Listening,

TomL

Guest Post: Roseanna snags some unexpected FM DX

Many thanks to SWLing Post contributor, Roseanna, who shares the following guest post originally published on her blog, The Girl with the Radio:


Unexpected FM madness!

I would like tho share with you a once in a lifetime Sporadic-E event that happened to me today along with videos of the catches I received during it.

It was about 12:00 UTC (1PM local time) and I was listening to NRJ on my personal FM transmitter (106.3MHz) when all of a sudden my pop music fuzzed and turned into classical music. It was then that I knew something was happening and I didn’t want to miss it!

I jumped up, got out my phone camera and started scanning around trying to find distant FM stations and my goodness did I get some amazing catches!

There was no tropo forecast for my area nor some of the places I heard and I wasn’t prepared in the slightest so I ask for your forgiveness on the shaky unprofessional footage and I hope you enjoy watching the following catches that I received!

For those interested my setup is a Sony ST-SE570 with a “bunny ear” telescopic aerial with the ground positioned vertically and the feed positioned horizontally. I put the feed to be facing at 90 degrees East to West.

Disclaimer: the order in which these stations were received has been altered to make this blog post more fun, the times in UTC are in the video titles for those of you interested in the chronological order in which I received these stations!

First stop: Czechia!

Click here to listen via YouTube.

This is an amazing catch to start us off; 10kW at 1300km with RDS!

Click here to listen via YouTube.

This one is even more impressive that the last one at 5.5kW with RDS, I still am surprised at these catches watching them back!!

Next stop: Romania!

Click here to listen via YouTube.

This catch is just insane. I have BBC Radio 2 on 88.1MHz and you can hear RRA and BBC R2 fighting to be heard!

Click here to listen via YouTube.

And this catch …. I have no words to describe my sheer amazement, surprise, shock and excitement hearing a station from Romania (Over 1800km / 1100 miles away) that is broadcasting at only 2kW. It is on the same frequency as France Musique broadcasting at 160kW which is much much closer; I still can’t believe I heard this at all!

After all that excitement we now stop over in Slovakia!

Click here to listen via YouTube.

This is a much less insane catch compared to the last few but it is still awesome! Disclaimer: I skipped a load of fading in the recording where it fades.

Click here to listen via YouTube.

And here is SRo 1 again, however this time a much lower powered transmitter compared to the last one and yet the signal is still really good and most of the RDS data was decode-able!

Click here to listen via YouTube.

Here is SRo 4, 20kW and some of the RDS decoded. an UnID was on 94.6MHz which made this quite awesome to get the RDS PI!

Click here to listen via YouTube.

And for our last stop in Slovakia we meet Fun Rádio, an 18kW station with RDS received!

Our last stop on our FM journey; Hungary!

Click here to listen via YouTube.

This is Retro Rádió a 50kW station in Hungary. It was broadcasting over BBC Radio Wiltshire and I even got RDS!

I hope you all enjoyed going on this radio tour of Romania, Hungary, Slovakia and Czechia with me, I certainly did!

Thank you ever so much for reading and watching and I hope to see you around for my next adventure!


And thank you, Roseanna, for taking us on your FM travels! Isn’t RDS an amazing tool for grabbing station IDs during these FM DX openings–? Well played! Again, many thanks as I enjoyed your FM tour of eastern Europe.

Impressive Transatlantic FM DX: Newfoundland to Northern Ireland on 88.5 MHz

(Source: Southgate ARC)

88 MHz Trans-Atlantic signals heard in Ireland

On Sunday the 8th of July 2018, there was a remarkable opening on the VHF bands across the North Atlantic. While there were plenty of strong multi-hop Sporadic-E signals on the 28 MHz and 50 MHz bands, the maximum qusable frequency did reach as high as 88 MHz at one stage.

Paul Logan in Lisnaskea, Fermanagh, Northern Ireland managed to catch CBC radio 1 on 88.5 MHz from Newfoundland, Canada at 22:35 local time (21:35 UTC). It is very rare for openings on Band 2 across the Atlantic and to date, only two people have managed to succeed in hearing North American radio stations.

FM DXing: Troy’s unexpected catch

Troy-FM-DX

Many thanks to SWLing Post contributor, Troy Riedel, who writes:

Thomas, if I were to read this on your blog, I would not have believed the following.

I live in Virginia nearly equidistant from RIC/Richmond Int’l AP (east of Richmond) and PHF AP (in Newport News). I had a 1:40 P.M. doctor’s appt. [July 12] and I took to I-64 East en route to the doctor near Newport News. My Silverado has an XM Radio that I typically listen to, but the reception is bad in the summer because of the wooded nature of the interstate.

I hit the “FM” button and I quickly found a station at 105.7. There were two other 105.7 stations that periodically interfered, but one station was dominating/booming. After music I heard commercials about concerts in Iowa. I heard an Iowa Lottery Commercial. And a Lasik commercial – yes, all from Iowa. I heard a weather forecast that definitely wasn’t for Virginia. After 10-12 minutes I got a station I.D.. It was KSUX Sioux City, Iowa. Sioux City, Iowa is 1,332 miles away or an estimated 22-hour drive!

KSUX dominated the airwaves until I got very close to my Newport News, VA appt. By then (around 12:55 P.M.) I had picked-up one of the other two stations that were competing on 105.7. It was a station on the Outer Banks, NC (about 2.5 hours by car away).

When I went back to my Silverado at exactly 2 P.M., the KSUX was barely audible as the Outer Banks, NC station was now the most clear. I drove back towards my home on I-64 West and after a few miles (5-10 at most) the third of the three stations became clear. The third station was “Kiss 105.7” originating in Richmond, VA. That means the Sioux City, Iowa station, 1,332-miles away, had obliterated the Richmond, VA signal from 12:30 P.M. to almost 1:00 P.M. even though at this juncture of my drive Richmond was 45-55 miles away.

The KSUX Sioux City, IA station … even though weak on the drive home … still occasionally popped through the airwaves to cause interference with the Richmond, VA signal.

If I hadn’t heard it, I would have never believed it. I did a quick check and I didn’t see anything regarding closer stations possibly simulcasting the KSUX signal. It appears to be 100% legit.

I’m dumbfounded. It’s a head scratcher for sure.

Thanks for sharing your experience, Troy. You, sir, were the recipient of some excellent FM DX openings!

FM DXing conditions

There are a few conditions that make for proper FM DX:

  1. Sporadic-E and tropospheric ducting (DXers often call this, “Tropo”)
  2. Meteor scatter, where signals bounce off of ionized trails left by meteors
  3. Also, when there is exceptionally high sunspot activity, FM signals have been known to bounce off the ionosphere (like shortwave signals)

I strongly suspect you were enjoying FM DX from sporadic E. If memory serves (and keep in mind, I’m currently vacationing in an off-grid cabin without Internet), we had a K Index of 5 or so on July 12–at least, I believe I heard a ham radio operator report this on 40 meters that day. I can confirm that the HF bands were absolutely obliterated parts of that particular day. Conditions were very unsettled for the HF (high-frequency) bands, but potentially excellent for sporadic E.

Fred Osterman writes about Sporadic E on DXing.com:

Sporadic-E propagation is caused by patches of intense ionization in the E-layer of the ionosphere (approximately 35 to 60 miles above the Earth’s surface). Signals on frequencies above 30 MHz normally pass through the ionosphere and into space. However, sporadic-E “clouds” are capable of refracting such signals back to Earth. The term “clouds” is an apt way to describe the patches of highly charged particles that form during a sporadic-E event. Like clouds, these patches move and are highly irregular in size and shape. It is possible to track the movement of a sporadic-E “cloud” by noting the locations of stations that fade in and out on a frequency as the cloud moves.

Sporadic-E propagation can occur any time of day or year. However, sporadic-E is most common from about mid-May to late July, with another peak a week before and after the winter solstice. Sporadic-E seems to be most common from about mid-morning to noon, local time, and again from late afternoon through the evening hours.

If you’re interested in chasing a little FM DX (’tis the season–!), read Fred’s full article about FM and TV DXing on DXing.com. What I like about Fred’s article is that it’s simple and easy to understand.

Post readers: Has anyone else enjoyed a little FM DX this summer? Please comment! This is a part of the DXing hobby that I rarely feature on the SWLing Post, but would love to highlight more often. Let me know if you’d like to write a guest post on this topic!

FM DX courtesy of the Camelopardalis meteor shower

Perseids meteor shower Photo: NASAHat tip to David Goren for sharing this article from Alltop:

“Just in case it’s cloudy where you are [tonight] when the new Camelopardalis meteor shower is set to hit, check out how you can still tune into the show without any equipment fancier than an AM/FM radio.

The key is to find a station on the FM dial, most likely below 91.1 MHz and tuned to a distant station, where the appearance of the large meteors expected from the shower will momentarily enhance reception as they fall to Earth.” [Continue reading…]

Ham radio operators, like my buddy Mike Hansgen (K8RAT), were already anticipating a little DX from these ionized trails. Mike suggests that you should listen on a clear frequency, or as he put it, “[n]ot only can the signal of a weak station be enhanced by a ping off a falling rock, but you can tune to a frequency where no signal at all is normally heard and listen for momentary bursts from never before heard stations.”

The only catch is that the best Camelopardalis viewing/listening time, for many of us, is between 2:00-4:00 AM. I hope I can wake up in time!
