Swiss state broadcaster confirms switch off of FM service by the end of 2024


In a press release dated Thursday 27th June 2024, the Swiss Broadcasting Corporation (SBC) confirmed that it would switch off all of the FM transmitters at the end of the year.

In a statement, SBC said..."Those who listen to the radio now largely do so via digital audio broadcasting (DAB+) or the internet, the SBC said on Thursday. Fewer and fewer very high frequency (VHF-FM) receivers are still in use in Switzerland, it said. Remaining, pure FM usage is stagnating at less than 10%."

A previous survey in 2020 had put the number of people listening on FM at 13%.

SBC continues... "In addition, maintenance of FM transmitters and investment in their renewal is expensive and disproportionate, the SBC said. In light of the organisation’s tough financial situation due to declining advertising revenues and inflation, further investment in outdated broadcasting technology is no longer justifiable. DAB+ and the internet offer better quality and a larger programme selection, are more energy and cost efficient, and can provide additional information in text and images."


FM was originally expected to be switched off throughout Switzerland by the end of 2024. The government extended FM licences for the radio industry for the last time in October 2023 to the end of 2026, after which radio stations in Switzerland will no longer be able to broadcast via FM, only digitally. The Swiss regulator OFCOM announced at the time that the final extension would give the radio industry the flexibility to complete the transition process from analogue to digital radio.

Trans-Atlantic opening on the FM band (87-102 MHz) - 27th May 2024


On the 27th of May 2024, a little bit of radio history was made with the very first reception of a trans-Atlantic FM radio station in mainland Europe. The map above shows the radio stations that FMDXer Mauricio Molano  in Cáceres in the west of Spain managed  to log including CHCM-FM in Marystown, Newfoundland on 88.3 MHz.

Log...

UTC QRG ITU Station, location Details, remarks Distance km kW ERP

12:06 90.20 AZR R80 Rádio, Pico da Barrosa (smg) 1674kms 0.5kw

12:15 87.70 AZR RTP Antena 3, Pico da Barrosa (RDP) (smg) 1674kms  40kw

12:50 88.30 AZR Rádio Clube de Lajes do Pico, Pico do Geraldo 1896kms 0.05kw

14:25 88.30 CAN CHCM-FM, Marystown (NL) Openline with Paddy Daly. Special log: double hop. First Canadian station received from Spain! 3985kms  27kw

As can be seen from the log, CHCM-FM was heard at 14:25 UTC and it's likely that the propagation mode was double hop Sporadic-E.



Mauricio writes... "I have managed to fulfil another of my DX challenges!: to catch an FM station from the other side of the pond!. It was this afternoon, during the opening of Es, which had started around 1200Z and brought me several stations from the Azores Islands with good signals. A couple of hours later, our colleague Larry Horlick (Coley's Point, NL) began picking up Spanish and Portuguese stations. 

In the first minutes of the opening was when I caught the CHCM-FM (Marystown) signal on 88.3 with 
VOCM programming. On 88.5 I have another signal but very weak. I assume it is CBN-1-FM CBC-R1 
Saint John's, but it will be difficult for me to identify it 100%. Both frequencies are very difficult in my 
listening place (Aldea del Cano, Cáceres) due to the presence of semi-local stations on 88.2, 88.4 
and 88.6 MHz. This year the DX season has started late here, but it has started very, very well!."



Mauricio also notes that he has two receiver/antenna systems. The first one is a three element Yagi points to the Canary Islands (south-west) attached to a RSPDuo receiver. The second one is a 4-element Yagi pointing to Newfoundland and attached to a Perseus with the FM+ converter.

In this case,  the station from Canada was actually heard on the antenna pointing to the Canary Islands!

Just to clarify, this isn't the first trans-Atlantic FM stations have been heard in Europe but all of the previous reception reports were to the UK and Ireland. This is the first time of a trans-Atlantic reception report on the Iberian Peninsula and mainland Europe. 



Larry Horlick, VO1FOG in Newfoundland... Larry is a long time FMDXer and he caught an impressive haul of FM radio stations from Portugal and Spain in the same opening. Larry has the advantage of a quieter FM band on his side of the Atlantic.


One of the major advantages of modern SDR receivers is that an opening can now be recorded and then be later reviewed afterwards to see what was heard. 

Larry's log is shown below and it's worth remembering that these are FM radio stations from the other side of the North Atlantic.


The frequencies range from 87.6 MHz to 102.4 MHz and the distances range from 3632 kms to 4136 kms.

Larry says his catch of the day was SER, Estepa, Spain on 98.3 MHz which has an ERP of just 250-watts.

In conclusion... While there have been trans-Atlantic openings on the FM band before, it is still a remarkable occurrence and worth noting. Every year, we see multi-hop Sporadic-E across the North Atlantic on the 28 MHz and 50 MHz bands and while it's of interest to those involved, it's really nothing out of the ordinary.

Band 2 signals (88-108 MHz) are different though and it's always interesting to see FM radio stations from either side of the North Atlantic reach the other side. The question always remains as to how high does an opening reach? Can it get up into the aircraft band at 118 to 135 MHz? What about 144 MHz? Spain to Newfoundland on the 2m band? Is it possible? Is anyone trying?

4,200km opening at 88 MHz between Africa and Brazil - Nov 2023


George, PU7MAN  on his FM DX Brasil Twitter account reports a 4,200km opening recently on the FM Band 2 between Africa and Brazil.

The station in question was the 8-Kilowatt transmitter of Radio Cote D'Ivoire near the capital Abidijan on 88.0 MHz. According to the FM DX Brasil account, the signal was heard at a remote receiving station at Nova Russas in the state of Ceará in the NE of Brazil.

The equipment used for the reception was an Airspy Mini SDR receiver with a 3-element Yagi for the FM band.

The signal was heard at 23:30 UTC. The Twitter post was on the 15th of November 2023 so it was perhaps at the same time as the reception?

Propagation Mode???... Nova Russas is located about 200kms or so from the Atlantic Ocean and isn't on the coast. I suspect it wasn't a form of tropo ducting as this is an area of low pressure systems at the equator and the distance was over 4000kms.

The propagation mode wasn't TEP (Trans-Equatorial Propagation) as the path ran almost parallel to the Geomagnetic Equator (E-W) and not across it (N-S).

There are some remarkable reception reports across South America on the FM band and some people attribute these to Spread-F. Was it that?

There is an audio clip embedded in this Twitter post...

At his home location in Sorbal, PU7MAN recorded this audio clip on the 14th of November 2023 after 23:00 UTC using a Kenwood BT3012u radio withe a Triax FM8s antenna...

Brazilian FM radio station on 77.9 MHz is heard in Portugal - 7th March 2023


This is a pretty amazing reception report. On the 7th of March 2023, SWL Hugh Cocks near the city of Faro on the south coast of Portugal managed to receive the FM radio station Radio Justica from Sao Paulo in Brazil on 77.9 MHz!

Just to explain the unusual frequency, Brazilian authorities are currently migrating radio stations from the Medium Wave band (AM) to a new eFM or extended FM band which goes from 76.1 to 87.3 MHz. This is just below the usual 87.5 to 108.0 MHz FM band i.e. Band 2.

The FM station on 77.9 MHz is actually Radio Cultura which is obliged to carry some of the Radio Justica programmes and it runs 5KW from the city of Sao Paulo.

You can listen to the reception report below and Hugh reports that it's about Brazilian employment law.

Hugh reports using a 3-element antenna with a low noise narrowband FET amplifier. The signal was at its strongest between 22:20 and 22:40 UTC.

Hugh writes... "The evening TEP starts around 2145gmt with Ch A2-A4 TV, fluttery signals as usual. Then if good 2210 or so tiny carriers from Ch5 TV 77.25MHz and then it may appear, often lower quality than this. Last night conditions were less but there was a new station on 76.9MHz playing non stop music, very weak."

Analysis... As the map shows above, the FM signal on 77.9 MHz from Brazil traveled about 7880 kms to reach the south coast of Portugal. While a signal at around 78 MHz is likely to propagate better than the usual 88-108 MHz Band 2 signals, it's still a remarkable distance.

As Hugh indicates, it looks as if the mode of propagation was TEP - Trans-Equatorial Propagation. The time of about 22:30 UTC is about right for evening TEP.

What seems unusual though is that the signal path doesn't seem to cross the Geomagnetic Equator at a right angle. Normally, FM radio stations from this part of Brazil might be heard in the Caribbean as the signals cross the Geomagnetic Equator at close to 90 degrees.

The lower the frequency then the higher the signal can deviate a lot from that required right angle. This often happens at say 28 Mhz or 50 MHz. Still though, it does seem to be quite far off 90 degrees for a signal around 78 MHz.

I'm also quite sure that the radio engineers in Brazil didn't expect the signal from their FM transmitter to reach the shores of Europe!

Further experiments... As this band is largely unused, it should be largely uncongested and quiet in other parts of the world. If these eFM radio stations in Brazil can reach Europe, can they be heard in the USA? Most of the south-eastern states in the US are closer to Sao Paulo than Portugal. Is anyone going to try?


Could it be heard further north in Europe? Say in late April or early May when the Sporadic-E and TEP seasons overlap? It only requires one Sporadic-E hop to reach the UK or Ireland but 22:30 UTC isn't the best time of day for Sp-E. Can it be done?

FM radio stations from Jamaica heard on 89 MHz & 96 MHz in Chile via TEP


Pipe, CE3SX / CE3SAD in Chile writes to say that he managed to hear two FM radio stations on 89.9 MHz and 96.1 MHz from Jamaica during a TEP opening recently.

CE3SX writes... "Stylz FM 96.1 from Port Antonio and KLAS 89.9 from Kingston, Jamaica heard in Chicureo, Santiago, Chile FF46pr Via Trans-Equatorial Propagation

Date: January 31 and February 01, 2022Hours: 21.46CEv 00.46 UTC and 22.03CEv 01.03 UTC

Maximum distance: 5,755 km"

As Pipe outlines, the distance is around 5,700kms and is approaching the maximum distance usually associated with Trans-Equatorial Propagation. 

A video clip of the reception is shown below...

Pipe also notes that regular reception TEP signals on the 88-108 MHz band from Columbia and he is using a 7-element Band 2 Yagi as designed by YU7EF.


CE3SX also notes that there are no 144 MHz stations in Columbia (HK) and Jamaica (6Y) to try on the 2m band.

As I outlined in a recent post, there are parallel paths from Brazil and Argentina to the Caribbean on 144 MHz during TEP openings and it's likely that similar paths are there further east from Chile to Columbia, Jamaica and Cuba on 2m.

FM radio station in Colombia on 93.1 MHz heard in Chile via TEP opening - 21st Nov 2021


21st November 2021: Back in October, I had intended to publish a post about reception of a FM radio station on 93.1 MHz in Columbia by Alejandro, CE3VRT in Santiago, Chile. The distance was 5000kms and the propagation mode was TEP - Trans-Equatorial Propagation.

I was so busy, I forgot to publish it and it remained as a draft! The post is now shown below for the 20th of October 2021. 

What reminded me of this was that CE3VRT heard the same radio station again on 93.1 MHz but this time the TEP signals were so strong, he was able to hear them with just the telescopic whip on his TecSun PL398.

Back in October, Alejandro was using a log periodic directional antenna outdoors on a mast to hear the signals but to hear FM radio signals on 93.1 MHz on the VHF FM band from 5000kms away with just a telescopic whip is really amazing.


20th October 2021:  Recepción FM DX via TEP (muy fuerte) "La Mega" 93.1Mhz Colombia, desde Stgo, Chile. Reception of 'La Mega' radio station in Colombia on 93.1 MHz by CE3VRT in Chile

Propagation mode: TEP
Distance: Approx 5000kms

"TEP opening (trans-equatorial propagation) very strong and somewhat short. The station tuned is "La Mega" from Barranquilla, Colombia, reception in the southern zone of Santiago de Chile (~ 5000km) using an Airspy HF + dual port and a logarithmic directional antenna for TV / FM."

Reception on Wednesday, October 20, starting at 21:30 PM local time (Oct 21 - 00:30 UTC)

Some local tropo on the FM band (88-108 MHz) - 17th Nov 2021


Wednesday 17th November 2021: I noticed some tropo signals on Band 2 (88-108 MHz) this afternoon and I spent a while doing a scan of the band.

The biggest problem is that I can hear around 75 signals on the band under flat conditions and that doesn't leave many gaps on the band for distant signals to come through.

I did hear four stations that were certainly via tropo propagation with distances ranging from 167 to 281 kms.


Under flat conditions, I can hear some of the main network FM stations on mountains that are about 130kms away.

While this reception report isn't all that unusual, it was still nice to catch these signals by just using the telescopic whip antenna of my TecSun PL-380 standing at a north facing window of my house.


It always impresses me how well this little radio works with just its own antenna.

4800km+ opening on the Band 2 VHF band between Chile and Columbia - Sept 2021


In some recent posts, I noted how there was openings on 144 MHz between the Caribbean and Brazil via TEP - Trans-Equatorial Propagation. The distances were in the region of 4600kms.

As can be seen from the graphic above, there was also an interesting TEP opening further west with Band 2 FM signals at 102.7 MHz in the north of Columbia being heard in Chile in early September, a distance of just over 4800kms.

The recording below is from Felip, CE3SAD in Chile who is an avid FM DX-er.

FM radio stations from Ghana are heard for the first time in Europe - 23rd July 2021

I only recently came across a report about how FM radio stations in Ghana on the 88-108 MHz band were heard for the first time in Europe on the 23rd of July 2021.


Mauricio Molano Sánchez is an active FM DXer in the west of Spain and on the 23rd of July 2021, he managed to log the following stations from Ghana in Africa...

88.3 MHz POTTERS FM Sunyani GHANA 3574 km 

88.5 MHz RADIO VISA  (AUDIO) Dunkwa-on-Offin GHANA 3734 km 

According to Mauricio, this was the first time that FM radio stations from Ghana have been heard in Europe.

He writes...."During a solid double hop sporadic-E opening towards Cape Verde, several weaker and more unstable signals appeared at 87.7, 88.1, 88.3 and 88.5 MHz. These last two stations are the ones that came a little stronger and for a longer time. It was possible to record identifications of both. The language used was English. After ruling out the Anglophone countries closest to CPV, the search ended in Ghana: the station at 88.5 was RADIO VISA from Dunkwa-on-Offin. 88.3 was POTTERS FM from Sunyani."

His full report can be found on his blog HERE

What I found of interest about this report was that someone in Spain managed to hear FM radio stations at a distance of about 3700kms. If we look at a map, this is what it looks like...


As you can see, the circle almost reaches Newfoundland. As far as I know, no-one in Spain or Portugal has ever heard a FM radio station from North America.

Back in June of 2021, Larry Horlick, VO1FOG in Newfoundland heard FM radio stations in Spain. At the time, some argued that it was not possible for anyone in Spain to heard North America because the band was too crowded. And yet, here we have an example of someone hearing double hop from Ghana in Africa.

If FM radio stations from Spain can be heard in North America then North American FM radio stations can be heard in Spain or Portugal. It's not a case of IF but WHEN will they be heard.

See my 88-108 MHz page for more examples of long distance reports.

FM radio stations from the Azores (87-93 MHz) are heard in Newfoundland - 23rd July 2021


Friday 23rd July 2021: Larry Horlick, VO1FOG in Newfoundland reports that he heard FM radio stations from the Azores on frequencies ranging from 87 to 93 MHz. The opening lasted one hour.

* * *

UTC QRG ITU Station, location Details, remarks Distance km Received by/in kW ERP Pol

* * *

It's interesting to see that Larry also heard the Azores two days earlier on the 21st of July.

Propagation Mode: It's almost certainly single hop Sporadic-E with a possible small tropo extension near the Azores. 

In a message, Larry VO1FOG notes that during this reception of Band 2 signals up around 88 MHz, the 6-metre band at 50 MHz appeared closed. It's very likely that there was a good single hop Sporadic-E opening from Newfoundland to the East but there is nothing out there in the mid-Atlantic.

As Larry notes, it's wrong to assume that just because there is nothing on 50 MHz, the higher bands will be closed. 

Analysis: Even though reports of FM radio stations from the Azores being heard in Newfoundland were only documented for the first time in 2021, it's likely that this 2300-2500km path is open every year. What is different this year is that there is someone activity logging these stations from the Newfoundland end.

While single hop Sporadic-E openings on Band 2 are nothing special, I would suggest that the ones between the Azores and Newfoundland are. Not in terms that they actually happen but in terms of what times they happen.

The more Newfoundland to Azores reception reports that are logged then we might be able to see a pattern of what is the most likely time of day that these openings happen. 

If the maximum usable frequency gets up to 88-108 MHz on a regular basis then there may be times that it goes up as far as 144 MHz. Add in a tropo duct at the eastern end and a trans-Atlantic path from Newfoundland to Spain or Portugal might be possible.

FM radio stations in Maine heard across the Atlantic in the north of Ireland - 22nd July 2021


Thursday 22nd July 2021: Openings on the FM band (88-108 MHz) between North America and Europe are very rare and it's always interesting to hear about these very high frequencies crossing the North Atlantic.

On the 22nd, Paul Logan in Lisnaskea in Co.Fermanagh in the north of Ireland managed to catch a short 5-minute opening to the state of Maine in the NE of the USA.

As the log from the FMLIST website shows above, Paul managed to log three separate stations at the bottom of Band 2 with frequencies in the range of 88 to 93 MHz.

To put this opening in perspective, this was only the 9th trans-Atlantic Band 2 opening for Paul Logan in a period of about 20 years.

For the reception, Paul was using a ELAD FDM S2 SDR receiver with a Band 2 9-element Yagi 8m above ground level.


Propagation Mode: As can be seen from the log, the distances were in the region of 4300kms. It's likely that the mode of propagation was double hop Sporadic-E i.e. 2 x 2150km hops.

FM radio stations on the Azores are heard again in N America - 21st July 2021

 


Wednesday 21st July 2021: At the start of July, FM radio stations on the Azores were heard in the USA. On the 21st, the North Atlantic path opened again with FM stations being heard in Newfoundland and Cape Cod, MA.

This is a log of what was heard by Larry Horlick (VO1FOG) in Newfoundland and Bryce Foster in the US...

Propagation Mode: It looks very likely that this was a case of single and double hop Sporadic-E again.

The distance from the Azores to Newfoundland is in the region of 2200-2500kms and this was most likely one hop Sporadic-E with a small tropo extension.

The distance from the Azores to Cape Cod in the US is 3830kms and this was very likely to be double hop Sporadic-E.

It's interesting to see that the path from Newfoundland to Bermuda was open at 21:00 UTC which suggests the location of one of the Sporadic-E clouds.

FM radio station on the Azores (87.7 MHz) heard across the Atlantic in Ontario, Canada - 8th July 2021


Thurs 8th July 2021: I reported recently on how a FM radio station on 88.0 MHz in Iceland had been heard near Cape Cod on the NE coast of the USA, a distance of some 3900kms. I can now report that a FM radio station on the Azores was heard in Ontario, Canada on the same day.

At 10:39 UTC on the 8th of July, William Hepburn near Grimsby in Ontario, Canada managed to hear RTP Antena 3 on Ponta Delgada in the Azores on a frequency of 87.7 MHz.

The distance was approximately 4,520 kms which is very close to the limit for double hop Sporadic-E.

William writes... "It took some investigation, podcasts, and a mix-up with Azores vs. Portugal time zones, but I managed to confirm reception of 87.7 RTP-3 Ponta Delgada, Azores (Pico de Barrosa xmtr) here in Grimsby, ON at 6:38-6:40 p.m. EDT July 8th. Top-of-the-band skip to Newfoundland was in at the time."

You can find a recording of what was heard on William's blog post HERE

For this extraordinary catch, William was using an ICOM R-8600 with a CHANNEL MASTER CM-3671 antenna.


Analysis: This is yet another example that Sporadic-E regions with a high maximum usable frequency (MUF) up as far as Band 2 (88-108 MHz) can occur over the North Atlantic. It may be possible that at times, one of the two regions may have a MUF up as high as 144 MHz.

It's interesting to look at the 4500 km circle and seeing how it reaches the Caribbean. 

Is there anyone in the Caribbean listening for FM radio stations on the Azores and the Canary Islands?

Is there anyone on the Azores or the Canary Islands listening for FM radio stations in the Caribbean?

If a FM radio station on Band 2 (88-108 MHz) can be heard then perhaps a contact on 144 MHz might be possible?

FM radio station in Iceland on 88 MHz is heard in the USA (3900kms) - 8th July 2021


Thurs 8th July 2021: Over the last few weeks, there have been some remarkable openings on the FM band in the North Atlantic. Links to post HERE

On the 8th of July, there was yet another opening in the North Atlantic when a FM radio station on 88 MHz in Iceland was heard by four individuals in the USA. Three in the state of Massachusetts and one in New Jersey.

21:53 UTC 88.00 MHz RÚV Rás 1, Stykkishólmsbær/Stykkishólmur-símstöð (3,945 kms) 18kW (Bryce Foster (K4NBF), Mashpee, MA, USA)

22:06 UTC  88.00 MHz RÚV Rás 1, Stykkishólmsbær/Stykkishólmur-símstöð (3,921 kms) 18 kW (Jeff Lehmann, Rockland, MA, USA)

The individuals concerned were... Bryce Foster, K4NBF (MA), Jeff ?? (MA), Keith McGinnis (MA) and Nick Langan (NJ).

As can be seen above, the distance was just over 3,900 kms. The likely propagation mode was double hop Sporadic-E (1950 kms x 2). 

However, that part of the Mesosphere where Noctilucent Clouds are found has been shown to reflect radio signals and that can't be ruled out.

One hop Sporadic-E reception on Band 2 over southern latitudes for example in Europe or the USA is really nothing special. When we start getting up into the Arctic regions, it's less obvious what the cause is for long distance VHF signals and that's why these reports are of interest.

FM radio stations from Spain & Portugal heard in Canada again - 7th July 2021

Back on the 21st of June 2021, there was a remarkable opening across the North Atlantic when a FM radio station in Spain was heard by Larry Horlick, VO1FOG in Canada for the first time. Post HERE


On the 7th of July 2021, there was another trans-Atlantic opening when Larry Horlick heard five FM radio stations in Spain & Portugal on frequencies ranging from 88 to 93 MHz.

UTC MHz Station, location (Distance km) kW ERP 

13:18 87.90 RTP Antena 1, Serra da Lousã/Trevim, Portugal, (3,657 kms) 34 kW

13:52 89.90 Los 40 Classic, Segovia, Spain, (3,916 kms) 2 kW

13:53 90.00 Cadena 100, Salamanca, Spain, (3,799 kms) 6 kW

14:08 93.10 RNE Radio Clásica, Valladolid/Cerro de San Cristóbal, Spain, (3,838 kms) 30 kW

14:15 88.20 Los 40, León/Las Lomas (CAL-LE), Spain, (3,728 kms)  4 kW


Larry reports that the opening started at 12:54 UTC and lasted until about 14:27 UTC (~90 mins). Some of the Spanish stations were really strong and nothing was heard above 93.1 MHz.

During the opening, Larry tried three different antenna types on receive.... a half-wave dipole (retuned from lo Band TV to  FM BC), a new 10 el K6STI Yagi, and  a discone. 

The Yagi was superior all the time even though it had to be pointed to a beam heading of 45 degrees to prevent overload and intermod from the local FM radio stations in St.Johns. (Spain is 084 deg)

Even being outside the 3 dB beam width, Larry reports that signals were MUCH stronger on the Yagi than on the dipole. The discone antenna was useless.

Credits: I must thank Paul Logan in Ireland and Jorge Garzon in Spain for confirming that these recordings. Both are very experienced FMDXers and it's great to have their expertise to call on to make sure there was no mistake.

Propagation Mode: It looks likely that it's a case of double hop Sporadic-E again with perhaps two 1900km hops.


The weather map for the day shows an interesting kink in the Jet Stream in the middle of the North Atlantic and these features have been associated with Sproadic-E regions overhead.

Questions...

Considering that this is the second time a Spanish FM radio station has been heard in Newfoundland in 3 weeks, it raises some questions...

I really wonder if this opening is exceptional or does this trans-Atlantic path on the 88-108 MHz band open a lot of the time? Do FM radio stations in Spain & Portugal cross the Atlantic on a regular basis?

And if FM radio stations from Spain are reaching Newfoundland then FM radio stations in Canada must be reaching Spain. Is anyone listening? Who will be the first person on the Iberian Peninsula to hear a FM radio station from North America?

105.9 MHz signal crosses the North Atlantic from Newfoundland to Ireland - 1st July 2021


1st July 2021: This was one of those remarkable days for VHF signals going across the North Atlantic. In an earlier post, I reported how someone in Cape Cod, MA in the USA managed to hear a FM radio station from the Azores Islands on 87.7 MHz. Later in the day, there was a remarkable opening on Band 2 from Newfoundland to Ireland.

Paul Logan in Lisnaskea in Co.Fermanagh in the north of Ireland managed to catch an extensive opening to St.John's, Newfoundland and logged no fewer than eight FM radio stations going from 88.5 MHz to 105.9 MHz. The distance was just over 3200kms.

The most significant of these loggings was that of CBAF-FM on 105.9 MHz as this is now the highest trans-Atlantic signal that has ever been recorded.

Here are the stations that Paul Logan heard...

For the reception, Paul was using a ELAD FDM S2 SDR receiver with a Band 2 9-element Yagi 8m above ground level.



Propagation Mode: First off, let's have a look at the tropo forecast...

The prediction certainly suggests that tropo ducting probably didn't play much of a role in this trans-Atlantic opening. Considering the distance was around 3200kms, it looks likely that it was probably double-hop Sporadic-E.

However, there are plenty of reports of Noctilucent Clouds at present and this region at about 80-90 kms above the Earth can reflect radio signals. Is the opening strictly Sporadic-E (1600kms X 2) or is the top of mesosphere region where the Noctilucent Clouds are involved as well?

In Conclusion: To put this opening in perspective, this was only the 8th trans-Atlantic Band 2 opening for Paul Logan in a period of about 20 years and the highest yet in terms of frequency. I can't help wondering how high did the trans-Atlantic maximum usable frequency go? 

Did it extend into the air band around 120 MHz? 

Is there any chance it might have reached 144 MHz?

Azores FM radio station on 87.7 MHz heard in the USA - 1st July 2021


There was another remarkable opening on Band 2 across the North Atlantic on the 1st of July when Bryce Foster, K4NBF near Cape Cod in Massachusetts in the USA heard RTP Antena 3 on the Azores Islands on 87.7 MHz.

The distance was in the region of 3,830kms and it is I believe the very first reception report of a Band 2 signal from the Azores in the USA.

From what I understand, the reception happened at 14:15 UTC and it lasted for about 35-minutes.

The FM radio transmitter had a power of 30 kW and was located at the Pico da Barrosa site which is about 900m above sea level on the island of Sao Miguel in the Azores.

Propagation Mode: The map below shows the predicted tropo conditions on the North Atlantic path...


It would seem that the most likely propagation mode was double-hop Sporadic-E with perhaps TWO x 1900km hops. 

Around the same time as this trans-Atlantic opening, Larry Horlick, VO1FOG in Newfoundland heard a Band 2 FM radio station in Bermuda. This would suggest that there was an active Sporadic-E region in the western part of the N Atlantic capable of supporting propagation on Band 2.

The tropo map above shows a bit of tropo to the west of the Azores but I don't think it's enough to account for the additional 1500kms that is required to be added on to one Sp-E hop of 2300kms.

In Conclusion: Back on the 21st of June 2021, there was a remarkable trans-Atlantic opening on the 88-108 MHz band between Europe and Canada. See links to posts on this page.

Now just over a week later, we have another opening across the North Atlantic and the first reception report from the USA of the Azores.

I suspect this more southern path opens on Band 2 a lot more than we suspect and it will hopefully encourage more people the NE of the USA to listen for trans-Atlantic signals.

Second Spanish station identified on 95.8 MHz in Trans-Atlantic opening on the 21st of June 2021

As outlined in a previous post, Larry Horlick VO1FOG in Newfoundland heard a trans-Atlantic Spanish radio station on 88.8 MHz on the 21st of June 2021. Thanks to recordings that Larry has sent on to me, another Spanish radio station has now been identified.


This one was RNE Radio 3 on 95.8 MHz from the 100 kW transmitter at Navacerrada near Madrid.

The distance to Newfoundland is in the region of 3940 kms and it was very likely to have been due to double hop Sporadic-E as outlined in the previous post.

As well as the distance being 200 kms or so longer, it's interesting to note that the maximum usable frequency (MUF) for this double hop trans-Atlantic path was 7 MHz higher and well into the Band 2 broadcast band.

This is a recording of the signal on 95.8 MHz as it was heard in Newfoundland...

This matches the podcast for the RNE Radio 3 programme on the day. Link HERE

Credit: Thanks to FM DXer Paul Logan in the north of Ireland who helped identify this station and who also heard a FM radio station in Quebec during the same opening.

Sporadic-E footprint: It's interesting to see how the path from Madrid to Newfoundland is almost exactly in line with the other reception of the RNE R5 station on 88.8 MHz near Zamora. 

Sporadic-E openings on the 88-108 MHz band are often like this with the stations heard stretched out in a straight line.

In Conclusion: I have covered the likely propagation mode in the earlier post which is HERE. As well as the distance and frequency of this second report, I am also struck by it's symbolism. 

If a FM transmitter on 95.8 MHz serving Madrid, the capital of Spain can be heard across the North Atlantic in Newfoundland then what can FM Dxers and other radio enthusiasts in the Iberian Peninsula hear from North America?

And on a final note. Larry observes that there were MANY other radio stations in Spanish during this opening. We were able to identify just two from the audio recordings.

Mystery Station: There is a third and final recording but it's just a song. 

It is the song 'Black Velvet' from Alannah Myles and it was heard from 11:55 UTC to 11:59 UTC on 89.9 MHz. Station? Location?

* * *

Update - 27th June 2021: The mystery third station has now been identified as Los 40 Classic. A visitor to the blog (FinnDX) saw the comment above about the mystery station and then used this website to check back through the playlist of stations for the last week... https://onlineradiobox.com/

This is a composite of a screen capture that I took before it disappeared. The website seems to be showing what the time was in my location which is an hour ahead of UTC during the Summer months.

12:54 Irish time = 11:54 UTC.

This is a 2kW transmitter located at Segovia which is just to the north-west of Madrid.

Spanish radio station on 88.8 MHz heard across the Atlantic in Newfoundland, Canada - 21st June 2021


Back on the 21st of June 2021, Paul Logan in the north of Ireland confirmed that he had heard a FM radio station across the Atlantic near Quebec City in Canada on 90.7 MHz.

I can now confirm that Larry Horlick, VO1FOG in Newfoundland, Canada managed to hear RNE-R5 Todo Noticias in the north-west of Spain on 88.8 MHz on the same day!

This is I believe the very first reception of a European FM station station on the 88-108 MHz band in North America.

It looks as if the signal came from the 80 kW transmitter near Zamora in Spain and the distance was in the region of 3780 kms.

I have two recordings which Larry very kindly sent on. The first one is at 11:46 UTC...

In the above recording, the cities of Zamora, Segovia and Burgos are mentioned. It would seem as if this is from the Castilla y Léon regional news bulletin which runs from 13:10 to 14:00 Spanish time.

This is the second audio recording at 11:50 UTC...

This one is a bit more noisy but the distinctive little 'jingle' between the news items can be heard.

Credits: I must thank Paul Logan in Ireland and Jorge Garzon in Spain for confirming that these were  indeed recordings of the RNE-R5 Todo Noticias radio station and that the transmitter site was near Zamora. Both are very experienced FMDXers and it's great to have their expertise to call on to make sure there was no mistake.

Newfoundland: On the receive side, Larry Horlick was using an ICOM IC-R8500 receiver with a centre-fed vertical dipole at 18m above ground level, cut for the lower end of the VHF LO TV band (essentially, non-resonant on Band 2).

Larry has only been listening seriously on the 88-108 MHz bands for a few weeks and he has already managed an incredible reception report. As well as being in a relatively quiet location (FM wise), he does have the advantage of being at the most eastern pat of Canada. 

It also helps that anything that Larry hears on the 88-108 MHz band is likely to be in English or French so any other language really stands out.

Propagation Mode: It seems very likely that this was a case of double hop Sporadic-E at 88.8 MHz.


The above diagram shows the signals 'bouncing' off Sporadic-E clouds at about 110kms above ground level and being reflected off the ocean at the mid way point. It's possible that this was also chordal hop with the signal going directly between the two Sporadic-E clouds without hitting off the Earth.

Note that the angles and height of the Sp-E cloud in the above diagram are greatly exaggerated. In reality, the angles are very shallow and are probably just a few degrees above the horizon.

This is another diagram showing the suggested path and the two Sporadic-E regions.


Paul Logan in the north of Ireland reports that he was hearing FM radio station from the Azores Islands for about five hours that day which he says was highly unusual. The MUF went up as high as 104 MHz.

It's likely that the Sporadic-E region responsible for the Azores to Ireland path was also responsible for the eastern first hop of the trans-Atlantic path between Spain and Newfoundland.

It's seems as if this eastern Sp-E region was present for several hours and it just required one Sp-E path at the right spot on the western part of the path to complete the 2 x 1890 km circuit.

In Conclusion: This really is an amazing reception report and is part of radio history in that it is the first proven reception of a European FM station on Band 2 in North America.

It also raises some interesting questions...

1) If someone in Newfoundland can hear a FM radio station in Spain then why can't FM radio stations in Newfoundland, Nova Scotia, Quebec and Maine be heard in Spain and Partugal?

2) If a Sporadic-E cloud in the western part of Atlantic can support a signal at 88.8 MHz then can it reach 144 MHz at times? And if so, could it couple into a tropo duct of say 1500 kms to complete the path to Spain or Portugal?

A double hop Sporadic-E trans-Atlantic path at 144 MHz is highly unlikely but a mixed Sp-E / Tropo propagation mode is much more likely.

The best thing about this trans-Atlantic reception report is that it now 'opens the door' on what might be possible. My hope is that it now raises awareness and more people will now listen for trans-Atlantic signals on the 88-108 MHz and 144 MHz bands.

Larry, VO1FOG informs me that he is building a 10 el K6STI Yagi for 88-108 MHz so hopefully we will get to hear of some more trans-Atlantic signals.

Addendum: This is a photo of the vertical Band 1 dipole that was used for the reception.

FM radio station on 90.7 MHz near Quebec is heard across the Atlantic in Ireland - 21st June 2021


21st June 2021: This was a remarkable day for VHF propagation with a very rare trans-Atlantic opening on the 88-108 MHz FM band.

As outlined in a previous post, Paul Logan in the north of Ireland managed to hear a radio station from Greenland on 88.5 MHz from roughly 13:00 to 14:00 UTC on the 21st of June.

Near the end of this opening, Paul also managed to hear a radio station near Quebec in Canada, a distance of approximately 4,270 kms !

The radio station in question was the 100 kilowatt transmitter of CBRX-FM-3 ICI MUSIQUE which is located at Riviére-du-Loup just to the east of Quebec City in Canada.

A short audio clip from Paul is embedded below...

This second clip which is very noisy is of weak music and a woman speaking in French.

Paul was able to listen later to the podcast version of the show online and it matches what he heard on the radio.

Additional info: Paul Logan near Enniskillen in the north of Ireland is an avid DX-er and has logged hundreds of radio stations on the 88-108 MHz FM band over a period of 20+ years. For the reception, Paul was using a ELAD FDM S2 SDR receiver with a Band 2 9-element Yagi 8m above ground level.


Analysis: With the opening to Greenland and now the 4270 km opening to Quebec, it looks as if this was a very rare Band 2 double hop Sporadic-E opening across the North Atlantic. 

While it it quite common for signals on say the 50 MHz band to cross the North Atlantic, the maximum usable frequency rarely reaches as high as the 88-108 MHz FM broadcast band.

Paul Logan has logged more of these trans-Atlantic Band 2 VHF openings than anyone else and this was only his 7th opening to North America in 20 plus years of listening.

As of 2021, not one single person in North America has heard a Band 2 radio station from Europe. Why?
