Hunting For NDBs In CLE 229
February 21st, 2018 |

| YPM - 274 courtesy: VE3GOP |
This coming weekend will see another monthly CLE challenge. The hunting grounds will be the 50 kHz swath from 270 - 319.9 kHz, with much of this is being shared by DGPS signals here in North America.
The last time this range was covered was in CLE 212, back in October 2016. Conditions were particularly disturbed back then, as described in my CLE 216 Results blog at the time. Propagation should be much better this time, I hope!
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 Pikangikum (ON) NDB, 'YPM', on 274 kHz. Although just a 25-watter, thanks to its large vertical, YPM is well-heard throughout North America. Will you log it as well?
Look for 'YPM's upper-sideband CW identifier, repeated every 10.5 seconds, on 274.352 kHz with your receiver in the CW mode.
If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing. You will soon know how well your system is hearing.
When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.
For example, 'AA' in Fargo 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.
Here are the final details from CLE organizer Brian Keyte, G3SIA:
Hello all
Our 229th co-ordinated listening event is this weekend, covering a 50 kHz
frequency range - about three times wider than usual.
Days: Friday 23 February - Monday 26 February
Times: Start and end at midday, your LOCAL time
Range: 270.0 - 319.9 kHz
Targets: NDBs (NOT the DGPS beacons)
We can expect very good propagation, but in part of the frequency range
it might be quite a challenge to tease out the NDB signals from among
the DGPS ones.
Any first-time CLE logs will be very welcome, as always.
Please log the normal NDBs you can identify that are listed in the range
(it includes 270 kHz but not 320 kHz).
Please send your CLE log to NDB List, if possible as a plain text email
and not in an attachment, with 'CLE229 FINAL' at the start of its title.
Show on EVERY line of your log:
# The Date (e.g. '2018-02-23' or just '23', etc.)
# UTC (the day changes at 00:00 UTC).
# kHz - the beacon's nominal published frequency if you know it.
# The Call Ident.
Those main items can be in any order within themselves, but BEFORE any
other optional details (Location, Distance, etc.) later in the same line.
As always, give details in your log of your own location and the receiver,
aerial(s), etc. that you were using.
If you send any interim logs, be sure to send a FINAL (complete) one.
You can find anything else to help you, including seeklists for your part
of the World, from the CLE page, http://www.ndblist.info/cle.htm
Joachim or I will send the usual 'Any More Logs?' email at about 18:00 UTC
on Tuesday so that you can check that your CLE log has been found OK.
Do make sure that your log has arrived at the very latest by 09:00 UTC
next Wednesday, 28th February.
We are hoping to make all the combined results on that day.
Enjoy your listening

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.
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.
Have fun and good hunting!

CLE 228 Results
Last weekend's CLE yielded a mixed-bag of propagation. Friday night's conditions were the best of the three nights here in southwest B.C., but others found things a little different ... such are the vagaries of radio's magic.All told, I logged 40 NDBs in the specified frequency ranges, with five of the logs being all time 'new catches'. After chasing NDBs regularly since the mid-80's, new ones do not come along too often. It's now fairly clear that as the Sun seriously starts to quiet down once again, propagation on the lower bands, especially the MF and LF part of the spectrum, is quickly improving ... a nice change over the past several years of continuous prop-killing geomagnetic activity during the downhill slide of Cycle 24. It looks as though things will be much better over the next several years as things get even quieter.
The highlight of the weekend was 'TOY' - 260kHz, from Tongoy, Chile. Although on the air for many years, this was the first time I have ever heard it ... on both Friday and Sunday evenings.
Located in coastal central Chile, 'TOY' runs some serious power at 3,000 watts. Along with its large vertical and rural location, I'm surprised I haven't heard it before.

The nearby airstrip in seaside Tongoy is apparently no longer in service and the beacon appears to be an 'enroute' navigational beacon, similar to the high-powered ones in many unpopulated regions of northern Canada.

I have to wonder just how long beacons of this type will be useful enough to maintain as most aero navigation is now reliant on much more accurate GPS, RNAV and RNP systems ... time will tell, but NDBs appear to be going silent with increasing frequency throughout North America.
Another highlight was 500-watter 'QY'-263kHz, located in the heart of Sydney, Nova Scotia and not logged here since 2013. 'QY's large vertical appears to be located in a residential area, but perhaps the beacon was there long before the neighbours moved in. I'll put 'QY' into the receiver's memory as a good indicator of propagation to the east.

Hunting For NDBs in CLE 228

| ZQT-263 courtesy: http://www.ve3gop.com/ |
This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be: 260 - 269.9 kHz and 440 - 1740 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 Thunder Bay (ONT) NDB, 'ZQT', on 263 kHz. It seems to be well-heard throughout most of North America as its reported 50W does a good job into a very high vertical. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 263.384 kHz.
If last month's great MF propagation continues into the weekend, we should see some great logs. Conditions are still very good at the moment.
If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing.
When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.
For example, 'AA' in Fargo 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 details:
CLE228 - FINAL DETAILS
Hi all,
Here are the final details for this weekend's Co-ordinated Listening Event.
This one uses some challenging frequencies and the possibility of hearing
some experimental amateur beacons. Any first-time CLE logs will also
be very welcome, however modest - it is not a contest!
Days: Friday 26 January - Monday 29 January
Times: Start and end at midday, your local time
Targets: Normal NDBs and Amateur beacons
QRG: 260.0 - 269.9 kHz
plus: 440.0 - 1740.0 kHz
Please log the beacons you can identify that are listed in those ranges
(not NAVTEX signals) plus any UNIDs that you come across there.
The range from 440 kHz gives some relaxing listening - it has wide
open spaces where you can often detect the carrier signals before
identifying them it from an offset. For Europe listeners most of the
targets are in the eastern countries where listeners will have a real
BONANZA - that's a lot! The CLE will be much more of a challenge
for those of us in Western Europe and in the rest of the World.
You can find details of the beacons in these ranges, lists and maps,
by clicking on the 'SEEKLIST' link in the CLE page
( http://www.ndblist.info/cle.htm )
We ask operators of the amateur beacons mainly around 474-478 kHz
to be on air during the CLE using a simple Morse mode which requires
no software to decode it. We are interested in anything operating IN
BEACON MODE in the range (no reports of any QSOs).
If possible, please include the amateur beacons' 6-character Locators
in your log - they are normally transmitted as part of the message.
Send your final CLE log to the List, preferably as a plain text email,
not in an attachment, with CLE228 and FINAL at the start of its title.
Please show on EVERY LINE of your log:
# The full Date (or Day no.) and UTC (the day changes at 00:00 UTC).
# kHz (show the beacon's nominal published frequency if you know it)
# The Call Ident.
Other optional details, Location, Distance, etc., go LATER in the same
line (or in footnotes). Any extra details about UNIDs, especially strong
ones that may be near to you (maybe their approximate direction, etc.)
will help us to discover more about them. Please make your log useful
to old and new members alike by ALWAYS including your own location
and brief details of the equipment and aerial(s) that you were using.
We will send an 'Any More Logs?' email at about 18:00 UTC on Tuesday
evening. From it you can check that your log has been found OK.
Do make sure that your log has arrived at the very latest by 09:00 UTC
on Wednesday 31 January.
The Combined Results should be finished soon after that.
Good listening

Have fun and good hunting!
CLE 226 / CLE 227 NDB Listening Event Results
CLE 226 and CLE 227, both running during the Christmas to New Year period, produced some excellent propagation on the MF NDB band in most parts of the world.
With the Sun behaving itself and acting more as it should for this time of the cycle, even the high latitude prop-challenged southwestern region of British Columbia enjoyed unusually good propagation. In fact, the night of January 1st was probably the best propagation I have seen on the NDB band in several years!
That night was particularly good to the east resulting in my first logging of a New Jersey NDB ... 50 watt RNB at Millville, on 363kHz.
In keeping with the Christmas spirit, CLE 226 was a north 'polar' event, with NDB's within the Arctic Circle being the targets.
Being away from home for several days, I missed out on the first four nights and got started on December 29th, but over the next few nights heard the following polar stations:

Here is the Cambridge Bay NDB (CB) on 245kHz. As well, the much weaker Gore Bay, Ontario NDB (YZE) can be heard underneath.
The second half of the event, CLE 227, was a 'bearing' event, where each listener picked one bearing from their location and logged NDBs (10 maximum) in countries or states that were located or touched on that bearing.
Since the normal propagation from my location favors the southeast, I chose a bearing of 107 degrees. This bearing passes through BC, WA, ID, MT, WY, NE, SD, KS, MO, AL, AR, TN, MS, GA, FL, BAH and BRAZIL, giving me a lot of possible coverage. As the propagation favored the east as well, I might just as well picked one that went through the Great Lakes and the eastern provinces. As it turned out, beacons were heard in most of my chosen regions except for the Bahamas.

As usual, my receiver of choice was the Perseus SDR in combination with my MF inverted-L, tuned to 300kHz. After listening to many hours of NDB recordings during the event, I was hearing CW coming from all sorts of things in the house, including the ceiling fan and the washing machine for the next several days!
More information on this particular CLE as well as NDB listening in general can be found at the NDB List website.
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.
Holiday Hunt For NDBs In CLE 226 & 227
The next CLE event will be the special Christmas holiday event and includes two challenges! CLE 226 covers any NDB north of the Arctic Circle, while CLE 227 is a 'bearing' event, with each listener chosing a particular bearing from their receiving location and seeing how many beacons can be heard from states, provinces or countries through which that bearing slices! You will have plenty of time to listen as well, since the event runs from Monday 25th December to Tuesday 2nd January.
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 (usually) on one small slice of the NDB spectrum.
Normally, December provides some excellent propagation but the planet continues to be bombarded with seemingly non-stop coronal hole streaming that can cause geomagnetic disturbances disruptive to MF propagation. However, often these 'disruptions' are not as dire as they first appear and MF propagation can remain robust or even be enhanced.
Listeners in Canada and the northern states as well as those in northern Europe will have a much better chance of logging the Arctic beacons. Most of these are large 'enroute' navigation markers with big antennas and plenty of erp ... they are heard very well.
A pdf list of all NDBs within the Arctic Circle can be downloaded from here.
If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing.
When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.
For example, 'AA' in Fargo 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.
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 a 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
Time to tell you about our Holiday CLEs.
Yes – we have two of them, running at the same time, something we have often done in the Christmas – New Year period.
The Early Advice for both CLEs is described here, but we shall treat them quite separately after this.
==================================
CLE226 - SANTA’S BEACONS
We'll be sharing Santa's attempts to use the NDBs north of the Arctic Circle (Latitude N67 degrees) as he navigates his weary reindeer on the last stages of their long flights back home.
Please tell us of any normal NDBs north of the Arctic Circle that you manage to log.
Days: Monday 25th December – Tuesday 2nd January
Times: Midday on 25th Dec to Midday on 2nd Jan, your local time
QRG: Normal LF/MF frequencies
Target: NDBs within the Arctic Circle, north of Latitude 67 degrees
That is similar to what we did way back in Holiday CLE059 (Christmas 2004).
There are about 130 qualifying ‘active’ NDBs currently recorded in RWW.
(You can see the old results from CLE059 in the CLE Archives Section,
http://www.ndblist.info/cledata/CLE59santa.pdf It only ran for 24 hours after midday on Christmas Day).
We do apologise to the listeners who are too far south to hear anything. (The further north listeners often miss out in normal CLEs, especially in the summertime when there is very little sky wave propagation for them).
The Final Details for the Santa CLE, CLE226, will follow in a few days.
===================================
CLE227 - BEARINGS CLE
Like CLE226, this is also a re-run, something that was very much enjoyed over 10 years ago - as CLE092 during a weekend in early June 2007.
Days: Monday 25th December – Tuesday 2nd January
Times: Midday on 25th Dec to Midday on 2nd Jan, your local time
QRG: Normal LF/MF frequencies
Target: Up to 10 NDBs in each Radio Country in your chosen direction
You choose a line in any one direction from you. Then try to log 'normal' NDBs in each of the radio countries crossed by that line - not more than 10 NDBs from each country.
Your line can be at any bearing of your choice - e.g. 123 degrees but NOT including the opposite direction (303 degrees).
Preferably use a Great Circle map to choose your line and to see which radio countries it cuts (a country is included if any part of it is crossed).
Remember that each USA and Australian State and each Canadian Province is a separate Radio Country. See http://www.ndblist.info/ndbinfo/countrylist.pdf
(If your line crosses the sea, any platforms roughly in that direction would also qualify as a radio country for the CLE).
The event will give you an opportunity to plan your own tactics. You could:
Try out a directional aerial
Include a favourite country or countries
Listen for NDBs which mostly have your favourite offset
Concentrate either on DX or more local reception
Exclude signals from the direction of your worst QRN
- any or all of those things, and more.
The aim is not to try and include as many countries or as many NDBs as possible, though you could do that if you wanted to!
TO CHOOSE YOUR BEARING, for non-dx loggings you could use an ordinary map (Mercator projection), especially if your location is near to its middle.
Better would be a Great Circle map centred on your location - you should find that https://ns6t.net/azimuth/azimuth.html is good and very easy to download and use. Just put in your location (e.g. Locator), choose a distance and click on ‘Create Map’. It misses out smaller countries, but reference also to a ‘normal’ map should cater for that.
Perhaps ideal would be Google Earth if you can download that (it is a powerful program for lots of purposes). Click on its Ruler icon and draw a line with the mouse. It tells you distance and Bearing ('Heading'). (Feel free to tell us about any other suitable Great Circle programs)
I can highly recommend the ns6t map generator as it produces a very nice great circle map, shown below for my location on Mayne Island.

I have yet to decide which bearing I will choose but 81 degrees looks promising from here as it cuts across BC, Alberta, Saskatchewan, Manitoba and Ontario while catching the northern edges of Minnesota and North Dakota.
(If you wish you could use any one remote receiver for your loggings,
stating the location and owner – and 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.
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.
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 Holiday 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.
Have fun and Happy Holidays to everyone.
CLE 225 Results
The recent CLE activity saw mixed conditions throughout North America. The general consensus was that propagation was just 'OK' but lightning noise continued to be a problem for some beacon hunters.
Here in B.C., propagation was fairly flat on all three nights, with Sunday night providing the lowest noise levels. Signals were generally weak and somewhat 'mushy' at times, with propagation still being affected by high speed solar winds and an elevated 'K' index.
North America results show the following stats:

As luck would have it, the three nights following the CLE have been fantastic on MF which seems to happen all to often.
Hunting For NDBs In CLE 225
 |
| LU - 214 KHz |
This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be: 190 - 239.9 kHz PLUS normal NDBs on 'half-way' frequencies nnn.5 kHz (from 190.5 - 999.5 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 (BC) NDB, 'LU', on 214 kHz. This is the beacon associated with Abbotsford Int'l Airport, Vancouver International's alternate for foggy conditions. It is located in a breathtaking mountain meadow location at the foot of the North Cascade Mountains. It's 500W Nautel drives a 100' vertical and with all of that space, I suspect a very robust ground system.
'LU' gets out very well and has been heard from Hawaii to New England and should be a good propagation indicator for many North American participants. Look for 'LU's upper-sideband CW identifier, repeated every 10.4 seconds, on 214.404 kHz with your receiver in the CW mode.
Usually November provides some excellent propagation as the summer thunderstorms have pretty much run their course but the recent warning of upcoming geomagnetic activity may, once again, mean something else in store for us. Often these 'warnings' are not as dire as they might appear and MF propagation remains robust or even enhanced.
If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing.
When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.
For example, 'AA' in Fargo 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,
Do try not to miss our 225th co-ordinated listening event - it starts this
Friday at midday. We can hope for good conditions, some comfortable
listening and opportunities to catch some good DX.
This should be ideal to try out a CLE for the first time.
Days: Fri. 24 - Mon. 27 November, Midday-Midday, your local time
Frequencies: 1) NDBs from 190 - 239.9 kHz
PLUS: 2) Normal NDBs on 'half-way' frequencies nnn.5 kHz
(from 190.5 - 999.5 kHz)
So for all of us it is a CLE in two parts - the first part is hunting for
the NDBs whose published frequencies are lower than 240 kHz.
The second part is hunting for the NDBs whose carrier frequencies
are 'half-way'. E.g. 284.5 DY, 333.5 VOG, 370.5 LB, 381.5 SJX (in MI),
390.5 ITR, 433.5 HEN ( Not nnn.6, etc. )
'Normal' NDBs - no DGPS, please.
(Most Europe listeners will hear few or none from part 1, while
listeners away from Europe will hear few or none from part 2)
The Seeklists from REU/RNA/RWW will help you – you will find them
from the link on the CLE page http://www.ndblist.info/cle.htm
Please send your CLE log to the List, if possible as a plain text email and
not in an attachment, showing 'CLE225' at the start of its title. (Loggings
from both parts can be shown together in the same list if you wish)
Please include on EVERY line of your log:
# The date (or just the day 'dd') and UTC (days change at 00:00 UTC).
# kHz - the beacon's nominal frequency.
# The Call Ident.
It is important to show those main items FIRST - any other optional
details such as Location, Distance, etc. go LATER in the same line.
Don't forget to give your OWN location and details of your receiver and
aerial(s), etc. Others will be interested to know, especially new members
- and old ones with memories like mine!
Also, please ALWAYS send your last log with ‘FINAL’ in the subject.
## That is important even if you send no interim logs ##
Listening on the 'half-way' frequencies means we might also catch some
interesting non-CLE beacons - please tell us about those too, but in a
separate list. If any of them are UNIDs whose carriers seem to be on
'half-way' frequencies include them in your main list of course.
Joachim and I will be processing the incoming logs – please look out for
our 'Any More Logs?' email at about 18:00 UTC on Tuesday evening,
with a list to let you check that your log has been found OK.
Joachim will again be making the combined results for us.
Do make sure that your log has arrived on the NDB List at the very latest
by 09:00 UTC on Wednesday 29 November.
Good listening
