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

(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.

After viewing so many interesting YouTube videos of various Perseus DX catches, I realized that my present method, using just my I-pad, had to change.

I asked a few of the folks that had been posting high-quality captures, what method they were using, and learned a bit about "screen recording" software. These programs allow you to capture, in reasonable definition video, exactly what is appearing on your computer screen....in this case, the Perseus user interface.
I ran across several freeware offerings, all requiring downloading and installation but reviews of most showed problems ranging from excessive malware along with the software, embedded viruses and glitchy performance issues.

I then came upon an online screen recorder called "Screenr" which required no downloading, no sign-up and had rave reviews from several sources. Screenr allows you to capture up to five minutes of video per file and then to either save it on your own system in .mp4 format for editing, upload it to a host of social media sites or directly to YouTube.

I fired-up Perseus and then Screenr to gave it a try. The first thing that popped-up was an adjustable frame that allows you to size your video so that just the wanted subject is visible and any additional screen clutter is not included.

As a test, I made two recordings and uploaded them to YouTube. To my delight, it all worked quickly and seamlessly although it seems that I need to do further experimenting with my audio level settings.

The first video shows two new broadcast band catches that were logged this week, using the new loop pointed to the east. KRJO in Monroe, Louisiana (1 kW) and CHTO in Toronto (1 kW) both in the top-end of the band.



The second video shows my two favorite NDB-band propagation indicators... AA (365 kHz) near Fargo on the ND/MN border as well as little 25-watter, YLJ (406 kHz) in Meadow Lake, Saskatchewan. Either of these make fine prop indicators for the 630m as well and can be heard from both the east and the west parts of the country.

The bottom line is that Screenr seems to work extremely well and is an excellent way of saving some of your SDR catches for web or blog site posting. As well, it could be used for making voice-narrated instructional videos limited only by your imagination....it gets a 5 out of 5 from me!

As Murphy would have it, and in spite of the low amount of solar activity, LF/MF propagation has been very poor since getting my new 10' x 20' loop in place. The few front-to-side nulling checks that I have done, have produced results varying from around 20db to 30db, depending upon the signal. I suspect the depth of null is also affected by the signal's arrival angle but there is still more to learn. The pattern seems to be very close to that of a typical circular loop...the classic figure-8 pattern illustrated below as shown on the Wellbrook data that came with my ALA100LN preamp.

More typically, the null is around 21-22 db as shown on this test while listening to the ground wave carrier of the YZA ndb (236kHz) located in Ashcroft, B.C., about 150 miles to the NE. As expected, the null is fairly sharp and the front / rear lobe, fairly broad.


One short check at dusk, produced nice signals from  CJBC, the French-language station in Toronto. The past few nights it has been very strong but with a strong echo effect. I wonder if there is more than one CBC outlet here (860kHz), such as a low-power repeater, causing the echo.


At the same time, while still fairly light outside, WCCO in Minneapolis had a nice signal just before sunset.


No matter how poor conditions become, it seems that the Hinchinbrook (Alaska) ndb, 'ALJ' (233kHz), is always strong....looping north.

My apologies for the video quality. If you know of any software available for making full-screen Perseus video captures so that I might improve my technique, please let me know. Presently I am just capturing them on my I-Pad which leaves a lot of room for improvement.

Hopefully conditions will only get better as the season progresses and I am able to give the loop a good workout....before it gets too windy!

"LU" - 214kHz Abbotsford, B.C.  Has been heard from W1-KH6

Yes, it's once again time for the monthly Co-ordinted Listening Event (CLE) for NDB hunters....the 186th event. These always interesting and popular affairs take place over three nights, with this one starting on Friday, Sept 26th at local noon and running until Monday, Sept 29th, local noon. CLE186 covers the frequency range of 350.0 to 369.9kHz only.

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

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.

Propagation to Alaska was much better than usual this morning. A two-minute Perseus recording at 1300z, about 45 minutes before my local dawn, revealed some excellent signals. Unlike many of the beacons in northern Canada, most of the Alaskan NDBs are not purposed for long-range use and run the standard 25 watts into 'T' or short loaded vertical antennas located right near the runway.

09/09/14 1300 529 SQM Level Island AK CO36

Highlighting the morning was my first "new catch" from Alaska in several years - 'SMA' at St. Mary's Lake on 230kHz. It has been on my morning check list for many many years but only today did it decide to reveal itself!

09/09/14 1300 230 SMA St. Mary's AK AP82 USB 231.085 no sign of a LSB

Reported to be running 70 watts, this particular beacon has never been reported to the RNA NDB list nor even heard by those listening in Alaska. I suspect either a very tough path or a system in need of a tune- up. A Google Map view appears to show a single vertical antenna but it may be one end of a 'T' support.

Hopefully conditions will continue to improve as there are still a few up there that have yet to be logged!
