What are some "easy" MW DX stations to look out for?

Post by daveB » 25 Apr 2018 21:26

Now that I've got the Shielded loop in some sort of working order I'd like to try it out in earnest in the next few days (before the FM SpE season starts). So what is likely to be about during the late afternoons and into the evenings? And is Transatlantic DX still possible this time of year?

A bit of an open question, but I'd like to get a feel for things.

Thanks
David

Hello Dave.

Transatlantic DX is possible ALL year. We just have a much shorter window in the extended daylight of the summer months.

The North Americans are the usual ones. You might try for 590 VOCM, 1010 WINS and CFRB, 1130 WBBR, 1390 WEGP, 1400 CBG (CBC network), 1440 WRED, 1500 WTOP, 1520 WWKB, 1540 CHIN (Chinese) and 1560 WFME.

Some to go at for starters.

South Americans may be less reliable on the whole, but you may hear Radio Puerto Cabello on 1290 from Venezuela and 1500 Radio Dos Mil, also from Venezuela.

There's Noti Uno from Puerto Rico on 1280, Harbour Light Of The Windwards from Carriacou on 1400, Radio Rebelde from Cuba on 1620 and WGIT Faro de Santidad from Puerto Rico on 1660.

Good DX! Let us know what you receive.

I think you mean 1500 WFED Washington DC?
WTOP is on FM in DC

1180 R. Rebelde Cuba is another one to try.

Yes, I sometimes live in the past regarding callsigns. As long as I don't start referring to the BBC Light Programme and the Home Service I should be OK. :lol:

930 kHz should be on the list as well - two Canucks and the Buffalo outlet regularly heard in the UK.

No mention of easterly stations so I'll kick it off. For early evening to mid evening in the current season.

1566 HLAZ Jeju South Korea

Even easier, the various Armenias: 864 - 1350 - 1377 - 1395*. These are hardly DX in wintertime but the summer challenge would be to see how early they propagate to your loop and how good the loop is at nulling out the co-channels.

* Haven't heard this one in April. The relay of Dengê Welat has possibly stopped.

Another famous one:

1521 - MRK China + Saudi Arabia

you might also try

558 Iran (now on air with 5 high power tx!)

1377 CNR China

1134 Kuwait

1431 Djibouti (unless it hasnt been taken down so far due to financial cuts..)

1575 Farda

Yes indeed it has, unfortunately...Was the best one from Armenia, the others suffer from heavy interference (864 / Eygpt - 1377 / UK-Ukraine - 1350 - UK,Hungary, I AM Radio.... 1314 / Spain, Romania...).

https://www.radioeins.de/programm/sendu ... stane.html
Ein Intermezzo blieben die Ausstrahlungen der kurdischen Dengê Welat über Sendeanlagen in Armenien. Mit dem Ende des März 2018 scheint jetzt ausschließlich die Station des russischen Sendernetzbetreibers RTRS bei Grigoriopol (Pridnestrowje/Transnistrien) zum Einsatz zu kommen.

Das nach einem halben Jahr wieder entfallene, zum 1. Oktober 2017 eingeführte Arrangement in Armenien sah neben Sendeplätzen auf den Kurzwellen 4810, 7320 und 7520 kHz auch eine abendliche Übertragung auf 1395 kHz vor. Auf die Mittelwelle verzichtet Dengê Welat jetzt ganz.

Thanks for all the feedback. Lots to become familiar with, including which direction the nulls are in :oops: . From the early hours of this morning I appear to have carriers that are just lifting into intelligibility on 1440 and 1560 around 0415 to 0500 UTC - just before sunrise.

But I've no idea of what TA conditions are like t the moment - more resources to have to learn about...

As posted elsewhere having realised the nulls are at right angles to the plane of the loop I was ble to confirm the loop's capabilty of nulling a signal on 252 kHz. I could get RTE at S7 on HDSDR but null it completely and get Algeria at S5 - in each case with no trace of the other station.

I guess you won't be around your receiver at the moment, but conditions have quietened down nicely and some transatlantic signals are in already. (0115 GMT.)

CHIN Toronto is present on 1540 at 01:15. Not bad considering that we are almost in May.

Typical - I decided not to record overnight!

How about giving it another try tonight, Dave?

Conditions are still settled. This in spite of a report of a possible aurora from that reliably inaccurate AuroraWatch UK site. (They generate their own spikes, internally.)

Well I've recorded overnight - with the loop aligned to max out any North American stations and null out the Spanish stations.

This is what I got after 3 am local time - and still a lot to check out.

On 1560 kHz https://app.box.com/s/2d4i43lu8t3c6wmi8aonnzx00l7fge9y
On 1540 kHz https://app.box.com/s/coa2edrx5k27nt0xe3y924l93hyb55l9

The one on 1560 kHz is the type of singing group you used to get on "Friday Night is Music Night", 1540 kHz, recorded on USB to avoid 1539 kHz, is some other singing, not quite as clear. There were quite a few carriers on North American frequencies after 2 am (I exclude the frequencies which match European allocations) which were not strong enough to produce audio.

I don't know what this reception represents in the wider context - but it looks like my first ever TA reception on MW.

No doubt WFME on 1560. That's definitely the music played by CHIN on 1540 at that time. You can hear how it sounds off tune slightly, as they are. My own recording also has another station in there in English. Presumed WDCD, which you might find fades up at times.

Thanks for confirmation of those two stations John. I found a third one on 1520 just before 03:00 UTC, which fades up nicely so I can clearly hear what the two male presenters are saying. I presume it will be WWKB from Buffalo New York.
https://app.box.com/s/xsq66tmu7sx496z5qg4rvygxhv1gwv0v

Around 02:15-03:00 UTCthis morning (May 2nd) 1560 and 1540 are present again. There are also weaker carriers on 1510, 1500 and 1470.

Out of interest - are my recordings weaker than your reception or similar? Obviously I want to get a feel for the performance of the loop. Also did you get TA signal at the low end of the MW on the 1st?

The simple answer is "about the same". I will record a quick demonstration shortly. This should give you a better feel for what to look for, bearing in mind that we don't usually hear much of interest during the lighter months. (Trying to avoid using words like "warmer" and "summer". ;))

You would benefit from having a flag antenna. Loops are great, but bi-directional - and very good at nulling to the sides.

I wish I could find the 3D plots of the flag antenna. The loop plot resembles a car tyre/rubber ring, while the flag (and ewe), well, picture an elongated balloon where somebody has pushed their finger deeply into one side, pressing it right into the middle. The rear nulls are not only both wide and deep, but also quite stable.

Just Google "3d antenna plots".

Dave, I think you might be hooked?

Thanks again John - not sure about "hooked" but the bait is dangling in front of me :D However SpE will soon take up all the available time.

I've considered a flag antenna but it needs support poles, and somewhere for the bottom wire to run which won't get in the way. And the main null would be in the wrong direction.The shielded loop is supposed to shield from electrical noise. The loop antenna was an achievable project - with some more development work to put into it.

No doubt I will be checking MW far more often when the daylight hours are much shorter.

BTW the word you are looking for is "cardioid".

Sounds like you will do well. Definitely give it another try come autumn when the Es have waved goodbye. You will be able to look to the Far East and other parts of Asia, if that interests you.

Hope the video above is useful. What a poor night, overall!

Yes, Es all the way for me too shortly. Still many, many Es files from last season to get through. When though? :(

A very informative video John - looks like the shielded loop is doing a reasonably good job. 1560 WFME was there from around 0200 to 050 UTC on the 2nd May - fading in and out. 140 and 1520 mainly as carriers along with a few others. Should be very interesting when conditions are good.

if you were around 0430z this morning the usual east coast stuff were very strong but from 0500z conditions dropped right off David

Ran out of disk space at just before 2 am as I hadn't reset the recording folder (Grrr!) but 1520 kHz was audible by 01:30Z and 1540 at 01:42Z.
