YJ-200KHz - Victoria Int'l

Listeners towards the central and southern portions of North America reported phenomenally good conditions this weekend, most unusual for a CLE event! Out west and here in BC, conditions were not noticeably enhanced and could best be described as kind of 'mushy' ... most signals were a struggle. The further south you went, the better the propagation became.

CFL Crud

Unfortunately, I am still struggling with noise pollution (cheap or failing CFLs) in a house about ten properties away, creating a constant 60 Hz hum and drifting birdies throughout the band ... as it was during the last CLE. Hopefully the owners of the home will return before the next CLE arrives!

Listening for NDBs is a practical way to check out your LF receive capability, should you be interested in developing a good 630m station or in following the nuances of night-to-night MF propagation.

Those of you following the CLE low frequency NDB listening events, will know that this past one was longer than usual, running from December 25th to January 6th. Once again, the sun demonstrated its nasty-side, right on schedule. Conditions from this part of the continent were dreadful, while others, further to the south, were not as badly affected.

The cause of the poor propagation was a continual coronal hole stream, from a very large area in the sun's southern regions, as shown here. Now it appears that Coronal Hole 649, in the north, is about to swing into a geoeffective position, and take over the task of disrupting propagation.

CLE189 covered the range of 275-425KHz, with the objective of logging at least one beacon (preferrably the farthest one) on each available channel (150 in total). There are a number of channels that have no NDBs as well as many that get completely clobbered by 1 Kw DGPS (digital QRM) navigation signals along the coasts and the Great Lakes. Additionaly, I was fighting the new noisemaker in my neighborhood, which has yet to be eliminated.

Here is a screen shot of my Perseus receiver, showing the crud being generated...every 60Hz and never constant...drifting in and out of the desired passband continually. The only way to hear signals was to wait until there was a short hole created by the drifters going by. I will be happy when this is issue is finally resolved.

My log shows 111 stations in total, a surprising number, considering the poor propagation and the QRM. If anything, this demonstrates just what a superb receiver the Perseus SDR is:

Once again, the 10' x 20' loop was employed for the entire affair, surviving two bad wind storms during the listening event.

10' x 20' LF Loop

As is usually the case, conditions deteriorated rapidly as the CLE weekend approached. Conditions varied throughout North America as those listening from the south-eastern regions of the U.S. reported much better propagation than those further to the northwest. Friday night appeared to be the best of the lot but all three nights were very much less than stellar.

The three-night event produced a total of 39 NDBs, with a couple of surprises.

This particular frequency range (370-384.9kHz) is a tough one for me, since my local pest signal, 'AP' is on 378kHz, smack in the middle of the listening range. 'AP's antenna is just .4 miles (2100') from my antenna and its signal is about 60db over S9.... Very loud!

AP to me...Courtesy: https://www.google.ca/maps/

The new 10' x 20' rotatable loop continues to work well. When pointed towards the east, it offers significant nulling of AP's signal and when carefully aligned to the deepest null-point, reduces the signal by almost 30db...but still leaves a very strong signal.

Using this 'deep null' position, I was (somewhat surprisingly) able to log another Canadian NDB (ZFA  Mayo Airprt, Yukon Territory) on the same frequency as AP. The ident-tone modulation frequencies are separated by 10Hz (408Hz vs 418Hz) which was enough to allow the very narrow ~3Hz Perseus filtering, combined with two notch filters, to reveal the 'ZFA' identifier between the 'AP' identifier. Listen for the weak 'ZFA' ident after the loud keying artifacts of 'AP', when they are transmitting just a steady tone.



The other surprise was the logging of 'PVQ' in Deadhorse, Alaska, way up on the extreme northern slope oil fields.

My last reception of this beacon was in March and conditions usually have to be very quiet, geomagnetically, to hear it at all. The coronal-hole streaming of this past weekend, putting the damper on LF propagation, makes this path very unlikely and surprising! See if you can hear the weak 'PVQ' identifier during its short appearance early on Saturday morning:


CLE organizer, Brian Keyte (G3SIA), reports 51 participants worldwide and over 2100 reception reports. All reports have been added to the RNA/REU beacon database.

As well, Brian will be publishing all results on the NDB Information page shortly.

All-in-all CLE188 was another enjoyable event....hopefully conditions will be better by this time next month and if you did not participate, maybe you will give it a try next time!

And...once again it's time for the monthly Co-ordinted Listening Event (CLE) for NDB hunters....the 188th event. These always interesting and popular affairs take place over three nights, with this one starting on Friday, November 21st at local noon and running until Monday, November 24th, local noon.








These listening events serve several purposes. They:

• determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date

• determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range

• will indicate the state of propagation conditions at the various participant locations

• will give you an indication of how well your LF/MF receiving system is working

• give participants a fun yet challenging activity to keep their listening skills honed

This time, it's a normal event, focusing on a small (~ 15kHz) section of the NDB band. Here are the details from event organizer, Brian Keyte (G3SIA):


Hi all,

The CLE Survey results are so interesting I almost forgot to send this!
Please join us in our 188th Co-ordinated Listening Event which starts
this Friday. All are very welcome - 'Regulars' and 'First-Timers' alike.
CLEs are not contests - if you enjoy taking part you are a winner!

Days: Friday 21st - Monday 24th November
Times: Start and end at midday, your LOCAL TIME
Range: 370 - 384.9 kHz

Just log all the NDBs that you can identify with their nominal (listed)
frequencies in the range (it includes 370 kHz, but not 385 kHz)
plus any UNIDs that you come across there.

Please send your CLE log to the List in a plain text email if possible
(not in an attachment) with CLE188 at the start of its title.
Show on each log line:

# The date (e.g. 2014-11-21, etc., or just 21) and UTC.
(the date changes at 00:00 UTC)
# kHz (the nominal published frequency, if known)
# The Call Ident.

Please show those main items FIRST - other optional details such as
Location and Distance go LATER in the same line.
If you send interim logs, please also send a 'Final' (complete) log.

As always, tell us your own location and brief details of the equipment
that you were using during the weekend.

I'll send the usual 'Any More Logs?' email at about 18:00 UTC on
Tuesday - you can check from it that your log has been found OK.All logs must arrive on the list by 09:00 UTC on Wednesday 26th
at the very latest.
I hope the combined results will be completed on that day.

To help your listening, seeklists are available via the CLE page

Good listening - enjoy the CLE

(If you wish you could use any one remote receiver for your loggings,
stating the location and owner - with their permission if required.
A remote listener may NOT also use another receiver, local or remote,
to make further loggings for the same CLE).

Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event.

The very active Yahoo ndblist Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome.

If you are contemplating getting started on 630m, listening for NDBs  is an excellent way to test out your receive capabilities as there are several NDBs located near this part of the spectrum.

You need not be an ndblist member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

Reports may be sent to the ndblist or e-mailed to either myself or CLE co- ordinator, Brian Keyte (G3SIA).

Please...don't be shy and do give the CLE a try....then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database.

The weekend CLE event described in an earlier blogpost provided the first real opportunity to put my new LF loop to the test. Actually, it has already passed the most important test...surviving a large 60+ mph windstorm, while I was away on a short vacation. Unfortunately, a 60' Douglas Fir, just a few feet from the loop, blew completely down...thankfully, over the bank, in the other direction. Cleaning it up will take a few weeks but should provide some good firewood as well as exercise.


Before leaving, I tied the end arms of the loop down just in case it might get windy, but it seems that the light PVC frame does not produce the same windage as my large wooden 10' loop frame.

Beacons logged over the three-night event:

VR-266 Vancouver Int'l (50W) - heard as far east as NC

How time flies...once again it's time for the monthly Co-ordinted Listening Event (CLE) for NDB hunters....the 187th event. These always interesting and popular affairs take place over three nights, with this one starting on Friday, October 24th at local noon and running until Monday, October 27th, local noon.

These listening events serve several purposes. They:

• determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date

• determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range

• will indicate the state of propagation conditions at the various participant locations

• will give you an indication of how well your LF/MF receiving system is working

• give participants a fun yet challenging activity to keep their listening skills honed

This time, it's a two-part activity, should you decide to chase normal DX beacons as well as those from your own country or state/province. Here are the details. 

Days: Friday 24th October - Monday 27th October
Times: Midday on Friday to Midday on Monday, your LOCAL time
QRG: Normal LF/MF frequencies (190 - 1740 kHz)
NDBs: Normal DX and 'HOME' ones (not DGPS, Navtex or Amateur)

DX:
Please try to log NDBs that are over 2,000 km / 1,250 miles from you.
If you have a wall map in your shack, you could draw a circle on it.
It will be accurate if it is a great circle map centred on your location.
(There are other easy and very good ways to find which NDBs qualify
for you - I will describe them in the Final Details email)

HOME:
Please also try to log NDBs in YOUR OWN radio country. For listeners
in AUS, CAN and USA, that means your State or Province.
It will be trivial for a few of us in tiny radio countries, very challenging
for a listener in, e.g., RUS (Eu). Most of us should have a fair list to
try for.
If we also mention any of our home regulars NOT heard, it will help
others to know about NDBs that are not currently active.

If you report on both parts, DX and HOME, I suggest you put them in
separate parts of your log. As usual, any UNIDs that you come across
will also be of interest - in a third part of your log.


Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted here a few days after the event.

Reports may be sent to the ndblist or e-mailed to either myself or CLE co- ordinator, Brian Keyte (G3SIA). It was very exciting to see two new reporters to last month's event after reading about the CLE right here. Hopefully there will be more first-time reporters for upcoming CLE187.

Please...don't be shy and do give the CLE a try....then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database.

ZVR - 368 Vancouver -  Middle Marker Rnwy 08R - reported as far as California

Now that CLE186 has come and gone, worldwide results will soon be posted by e-mail (to all those submitting reports) as well as to the CLE website. CLE organizer and data-cruncher Brian Keyte (G3SIA), indicates that 50 logs (and over 2,000 reports) have been submitted, including two first-timers - Graham (VE3GTC) near Ottawa, ON and Hans (BX2ABT) in Taiwan. It's always great to see new activity, especially on LF!

As is usually the case with CLE's, propagation conditions begin to deteriorate shortly after the announcement of the upcoming event. By the weekend's arrival, conditions are usually much worse than earlier in the week and such was the case once again! In North America, lightning activity and mediocre propagation dominated the three-night event, with the consensus of opinion giving the nod to Saturday night and early Sunday morning as being the best period.

Here on Mayne Island, Friday night was pretty much a wash and only the stronger signals made it through the din and into the log. A twilight check on Saturday evening indicated improving propagation and less lightning, renewing optimism that the entire weekend would not be a wipeout.


Since purchasing the Perseus SDR earlier this year, I have been using it exclusively for the past few CLE's. I have been exploiting one of it's main features....the ability to record the entire band overnight and then tune through the band the next day, as in real time. I no longer had to prop my eyelids open until 0100 or later, or to leave a sound sleep to journey out to a cold shack to hunt the pre-sunrise band for anything new....yes, Perseus has made it possible to DX while I sleep!

Now the very concept of this horrifies many of the 'purists' and I myself held-out for several years before venturing over to the darkside...but...embracing new technology along with its associated new learning is what is important. If I get to sleep-in because of it, even better!

So....that's the way it is supposed to work, but due to operator error, Perseus failed to launch on Saturday night, and the best conditions of the CLE were missed altogether. Having seen the error in my ways, the perils of Perseus will, hopefully, not strike again!

Conditions on Sunday night were noisy once again, although not as bad as Friday, and the following log was gathered after parsing through my overnight recordings.


I have, over the years, logged all of these beacons before, except for one..."OKT" in Yoakum, Texas...new catches are always nice and are harder to find  it seems. The Google Map's 'street view' shows what appears to be a nice top-loaded "T" antenna at OKT:

It was nice to salvage Sunday night but I'm still a little bummed about missing the best night of the weekend...at least I had a good night's sleep.
