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

Posted: 26 Jun 2021 12:51 AM PDT https://ei7gl.blogspot.com/2021/06/second-spanish-station-identified-on.html


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?

15,000km+ opening on 50 MHz between Australia and Europe - 25th June 2021

Posted: 25 Jun 2021 10:00 PM PDT https://ei7gl.blogspot.com/2021/06/15000km-opening-on-50-mhz-between_01776813359.html


Friday 25th June 2021: Yet another opening on 50 MHz between Australia and Europe.
The map above is the FT8 report for VK4MA who had paths to around 17
European stations. When I checked his log on the PSK Reporter website, the
path for him was open to Japan at the same time that he was hearing Europe. Looking back through my recent posts about these recent Europe to Australia openings on 50 MHz, they all seem to be around the same time when they do occur... i.e. mainly 05:00 to 06:00 UTC.
I checked and the sunset for Brisbane (VK4) seems to be at 07:01 UTC while Adelaide is 07:43 UTC.
The regular pattern of the openings from Australia to Europe does suggest
to me that the time of day in Australia is be a factor. This is a map of
the daylight at 06:00 UTC which shows that sunset in the east of Australia doesn't happen for another hour.


If I use HF propagation prediction sites like PROPPY, then I can see a big spike in the MUF between the east of Australia and Japan at around 06:00
UTC. Is it high enough for 50 MHz? Is it TEP related?
