'XX-344' - Abbotsford, BC

This coming weekend will see another CLE challenge. This time the hunting grounds will be:  335.0 - 349.9 kHz.


For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.






A nice challenge in this one is to hear the Abbotsford  NDB, 'XX', on 344 kHz. 'XX' is located about 40 miles east of  Vancouver International (YVR) and a few miles SW of the Abbotsford Airport, YVR's alternate for those foggy winter nights. 'XX' is a 500-watter and is well heard, having been logged from the east coast to Hawaii and is a good propagation indicator for listeners in eastern North America. Look for 'XX' on 344.404 kHz with your receiver in the CW mode.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. With your receiver in the CW mode, listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are tone-modulated with a 1020 Hz tone approximately.

For example, 'AA' in Fargo, MN, transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

From CLE organizer Brian Keyte, G3SIA, comes the usual 'heads-up':

Hello all

Our 218th Co-ordinated Listening Event is less than a week away.
Just a normal CLE using a busy range of frequencies which usually attracts a lot of interest.
First-timers' CLE logs will also be very welcome, as always.

Days: Friday 21 April - Monday 24 April
Times: Start and end at midday, your LOCAL time
Range: 335.0 - 349.9 kHz

Please join us wherever you are - just log the NDBs you can identify
having their nominal frequencies in the range (it includes 335 kHz
but not 350 kHz) and any UNIDs that you come across there too.

We last concentrated on these frequencies for CLE200 in Nov. 2015
when 55 of us joined in.

Location: Surrey, SE England (CLE coordinator)

(Reminder: You could use any one remote receiver for your loggings,
stating its location and owner - with their permission if required.
A remote listener may NOT also use another receiver, whether local or
remote, to obtain further loggings for the same CLE). 


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 there a few days after the event. If you are a member of the ndblist Group, results will also be e-mailed and posted there.

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. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

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. 

'First-time' logs are always VERY welcome!

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

Please ... 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 to help keep it up-to-date.

Good hunting!

If you follow Bob Heil’s show Ham Nation you’ve surely noticed that he’s taken a keen interest in reviving the Amateur Radio tradition of project building. Here is Ham Nation episode 292 where they walk through an easy pine board power supply project:

There’s no better way to learn than by doing. Luckily, we’re experiencing a real renaissance in kit building and general tinkering. It’s a great trend!

This Easter weekend we decided to go out with the dogs and combine three hobbies, walking, geocaching and amateur radio whilst taking the opportunity to visit some radio related relics of World War II and the Cold War on the Lincolnshire Wolds.

Following a recent presentation at the South Kesteven ARS by David Gordon G6ENN where he talked about his successful portable operating I was encouraged to constructed a simple dual band 'flower pot' antenna (design from VK2ZOI) using some RG58 coax and 25mm conduit.

Completed 2m/70cm Flower Pot

My previous attempts at portable operating have largely involved HF and slightly heavy equipment (my Yaesu FT-857D and Sealed Lead Acid batteries) but I decided this time to try VHF/UHF as we were going to one of the highest spots in the area. This allowed me to travel light just taking along a Baofeng UV-5R and the antenna sticking out of the rucksack.

Just setting off with Boris & Eddie

Parking up in Donington on Bain we had a short 4 mile circular walk planned allowing the wife to collect a dozen geocaches along the way with a short detour at the top to visit RAF Stenigot. The walk climbs to the top of a hill, but it isn't a long ascent by any means or overly strenuous. The view back included the impressive Belmont Transmission Tower (just visible over my shoulder in the picture above) which before it was shortened in 2010 was reputably the tallest structure of its type in the world.

Belmont Transmission Tower

The Lincolnshire Wolds is the highest area on the East of England between Yorkshire and Kent and so there are many structures that take advantage of the elevation. In addition to Belmont we could see the Radar station at Wolds Top/Normanby Hill and Lincoln Cathedral in the distance, but we were interested in what was in front of us the remains of RAF Stenigot.

View back

RAF Stenigot was part of the Chain Home radar network during World War II, this early system used large antenna arrays suspended from large towers, one of which is now preserved as a Grade II listed structure which is still used by RAF Aerial Erector School for selection tests for possible recruits.

After the Second World War, the site was retained and in 1959 it was upgraded to a communications relay site as part of the NATO ACE High system, which involved adding four tropospheric scatter dishes. The site was decommissioned in the late 1980s and was mostly demolished by 1996 but the toppled dishes remain.

While on private land with no public right of way it is a simple matter to follow the field edge to get quite close, the actual site has been secured to prevent vandalism and is now home to a herd of bulls to deter trespassers!

We stopped in the shadow of the dishes for a drink and some refreshment and I got out the radio and attempted to make some contacts, but sadly it seemed like everyone was in still in bed. I could open quite a few nearby repeaters and put out calls but again nothing heard, hopefully ET had better luck!

ET Phone Home!

Checking the equipment when I got home it seems the Baofeng radio has developed quiet TX audio, so it is likely people couldn't hear me. I haven't used these cheap radios much and know they are prone to issues but thought mine was okay. Oh well, at least I looked the part and got a few odd glances from the few walkers and locals we saw. What I didn't realise at the time is the hill is also the site of GB3LC but I did spot some amateur radio antennas nearby.

It really was a great morning walk in a part of the country which is on our doorstep but haven't really visited before. Getting up close to the dishes and the Radar mast was fascinating.

What's more you aren't far from the Lincolnshire Coast, so after our walk we went to Mablethorpe for the afternoon and fish and chips which were well received.

Might look at activating Wolds Top in the near future as it is also a SOTA summit!

I had some spare time today  and was able to get on the radio! Over the past month or so it has been lots of work and no time to play radio. Today while on 20m CW  I was able to snag HA7GN from Hungary, IQ0PG from Italy I was given special report number of UN90ARI1.  According to their site this qualifies me for there ARI 90 years award. The last contact of the day was IO0MDC again from Italy and this call was in celebration of 20 years for the Mediterraneo DX club. I was thrilled with
these short contacts and I really was only on for about 20 min's. On a side note.........I have posted in the past that I am the proud owner of an Elecraft K-pod. This thing works great and is a great asset to the shack. It has 8 programmable push buttons, at my age I loose track of what is on what button! I came up with an idea of adding some magnetic strips with the naming of each of the buttons. Since they are magnetic I can remove them when the button macro has been changed or rearrange them if need be.

This is Episode #187 of Linux in the Ham Shack. In tonight's episode, we have a special round table discussion. We've brought in listeners and a total outsider to talk about--well, stuff. Topics include 630-meter operation, ham radio in Cuba, photo editing applications, svxlink, qtel, thebridge and a whole lot more. We also discuss marching for science. But mostly, we just had a great time and hope you do, too.
