The 2018 Novice Rig Roundup (NRR)
February 15th, 2018 | 
Author: 
One of the most enjoyable operating events of the year is fast approaching -- the Novice Rig Roundup or 'NRR'. Technically, it is a contest, but I have the feeling that most participants think of it as just a lot of fun and a nice opportunity to hear and work some of the great old 'classics' of the past -- rigs that were used when they were teenage Novices or rigs that they could only drool about owning, back in those formative years when they each discovered the magic of radio.
 |
| WN4HQW's '62 Novice station (now N4CF) |
The dates to remember are 0000 UTC March 3 - 2359 UTC March 11 and this multi-day opportunity is, for me, what makes the NRR so enjoyable. With a nice diversion from the usual 'contest frenzy' associated with standard weekend operating events, the NRR can be enjoyed throughout the week, whenever you choose to participate. If last year's operating patterns continue, you should find activity at any time of the day ... and even more as sunset arrives.
With the fast-approaching solar minimum, we will be hard-pressed to relive the glory days of worldwide 15m propagation, as even last year's event proved to be tough on this band. With a little luck and, hopefully, a well-timed solar flare, we may get lucky! If you operate during the daylight hours, please get on 15m and give it a shot ... and be sure to announce your activity on the NRR's sked and chat page here, so that others will know where to find you, especially if you are rock bound in true Novice fashion. With our present spotty conditions, we need all the help we can get and the sked page proved a very valuable asset during last year's affair.
Although technically not required, if you plan to participate it's best to obtain your own NRR number, which is an easy 30-second process.
Additionally, there is an online logger where participants can post their daily log. The nifty logger also keeps track and figures out your score as it goes and no 'after contest' log needs to be submitted. If you plan on submitting a log, the logger is a requirement. The logger will also require you to set up a 'log-in' and once again, a simple 30-second process will take care of that from here.
Stations may run either crystal-control or VFO or can switch between either method ... the online logger will keep track and score things appropriately. Stations running in both Novice 1 and Novice 2 categories (probably most common), will be eligible for prizes in both modes if they make at least ten contacts using a Novice 1 station or if they work ten Novice 1 category stations.
All of the rules and information can be found on the NRR's excellent website. As well, the soapbox comments and station pictures from last year's NRR may provide the inspiration that you need to spark-up your own activity in this year's event ... from what I can tell, this year will be bigger and busier than ever!
There is also a dedicated NRR Yahoo Group, often the source of much valuable discussion.
Last year I ran my homebrew Longfeller in the (now eliminated) QRP category, and had a ton of fun. You can read about it here. This year, I have refurbished a nice Drake 2NT that had been gathering dust in the basement for over 25 years ... it's all ready to go now, but a problem with the VF-1 VFO has arisen. The combination works well on 40m and above but on 80 it's a different story. The VFO runs on 160m and it seems that the 2NT balks at the idea of doubling in the buffer stage to 80m. Unless I solve the problem, I'll be rockbound on 3579, 3550 or 3560kc. ... it was 'kilocycles' back then, which always seemed to make more sense to me than 'kilohertz'.
If you have access to the web while operating, be sure to bookmark and check-in to the NRR's realtime chat page. Many ops that are crystal controlled will announce their operating frequencies, making it easier for you to find them ... sometimes way up or down from the normal NRR watering holes of ~ 3550 - 3650 kHz, 7100 -7125 kHz, 21.100 - 21.150 MHz and 28.114, 28.120 MHz ... and don't forget to check the colorburst crystal frequency of 3579!
Of course with the large number of rockbound stations (on crystals), be sure to look above and below these frequencies. It's good practice to listen well above and below your own frequency as well, for anyone answering your CQ who may be up or down the band on crystal control. Unlike today, this was very common practice back in the Novice days!

You still have time to get that old clunker on the air but if that's not possible, you can join the fun with your modern rig as well ... all are welcome to jump in and have a great week of radio-fun. I think you will be surprised, just as I was last year, how good some of these old classics can sound ... and you'll hear some great bug-fists as well.
As indicated on the NRR website, this is "more of an EVENT than just a typical contest ... once again taking our OLD ham radios off the shelf and putting them to use again! "
See you in the 2018 NRR!
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

Location: Surrey, SE England (CLE co-ordinator)
---------------------------------------------------------------------
If you are interested in some remote listening - maybe due to local
difficulties - you could use any one remote receiver for your loggings,
stating its location and with the owner’s 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 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 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.

The “BK 1929 QSO Party” From BC
With this being my final blogspot of 2017, let me take this opportunity to wish all readers and radio friends season's greetings and good health and happiness in the coming new year. It's hard to believe that this is blog posting #470, having started blogging in the spring of 2014 ... how time flies when you're having fun. It flies even quicker when your both old and having fun at the same time!The AWA's annual premier operating event, the "Bruce Kelley 1929 QSO Party", affectionately known as the "BK", has once again come and gone and some have already begun the countdown to next year's fun!
The hoped-for good conditions, not seen in the past few years, almost became a reality as it wasn't a complete washout like last year's event. Spread over two consecutive Saturday evenings, the best conditions were on the second night, but with just a few east coast stations making it into the log. Several of the 'eastern regulars' were just never heard here, as the band was not quite up to par ... maybe next year will see a return to the great low band conditions of the past.
As usual, I began on 40m, shortly after the BK start at around 1500 local time, and a good hour and a half before local sunset. Usually, 40m isn't too productive until closer to sunset and then, only briefly, as eastern stations have usually moved down to 80m just as the band opens up out here. Contacts with KØPK (MN) and K4JYS (KY) were followed by exchanges with locals VE7BDQ (John) and new BK'er VE7CNF (Toby).
As always, K4JYS's 1929 designed Hartley oscillator using a 210 at 20W input, made it up to this region consistently and was 559 with over an hour of daylight remaining.
 |
| K4JYS's 210 Hartley |
John and Toby both chose to build relatively rare 1929 designed Colpitts oscillators and were both exceptionally strong here.
 |
| VE7BDQ's Colpitts 45s |
 |
| VE7CNF's Colpitts 45s |
Here is a recording of VE7CNF's Colpitts on 80m thanks to Mark, VA7MM.
KK7UV, Steve in Montana, called in next, using his painstakingly restored REL MOPA (Master Oscillator Power Amplifier). His 5W input was a solid S7 here.
 |
| KK7UV's REL |
Moving down to 80m just after 1700 local time, netted contacts with WB9WHG (WI), KØSM (NY), W2ICE (NY), WA9WFA (MN) and W8KGI (NM) all before dinner hour.
I think Scott (WA9WFA) may be the only other Colpitts user and was a solid 569 here using his pair of 10s at 20W input.
 |
| WA9WFA's Colpitts '10s |
The band slowly deteriorated later in the evening but not before working N4GJV (NC) on his 3W Hartley oscillator and then finishing with back to back contacts with KØPK and KØKP, both in MN.
 |
| KØKP's Hartley '10 |
Weekend two started again in daylight on 40m, with the 25W Hartley signal of W2AN in New York booming into Mayne Island at 589! Truly remarkable with sunset being over 30 minutes away. What looked to be a really good night shaping up turned out to be disappointing once again ... but for a few strong 'spotlight' openings to the east, most east coast signals evaded me once again.
 |
| W2AN's Hartley 203A |
Back on 80 right at sunset brought W2AN (NY) once again followed by WØNYQ (MN) with his 4W TNT doing a nice job at 569.
 |
| WØNYQ's 4W TNT with a 245 |
80m contacts were completed with N8YE (OH), NO3M (PA), W3GMS (PA) and the highlight of the evening, N2OUV, Joe in NY, running his 10W '29 Hartley and peaking 579 on the transcontinental path. I rarely work Joe but when I do it's always a delight as it was his YouTube video that originally inspired me to become a '29 builder and participant!
 |
| N2OUV's 211 Hartley |
Hats off as well to Joe, W3GMS in PA whose rare original 18W TNT was putting an impressively solid signal into the west coast for over an hour ... he must have a great antenna.
 |
| W3GMS's Original '29 210 TNT |
Once again, I used my homebrew MOPA using type '10s for all contacts but I could have just as readily used my Hull Hartley or TNT as there was absolutely no wind on either weekend ... a very rare happening here on the ocean!
 |
| VE7SL's '10 MOPA |
One great positive was the appearance of several newcomers to the '29 Party, which seems to be growing in popularity each year. There is still a lot of interest in '29-style construction it would seem and if this is something that you might like to try for next year's event, here are some helpful guidelines from some of my previous blogs to help get those homebrew juices flowing. It's never too early to warm-up that soldering iron!
There is also some hands-on '29-style building info on my website that can be reached here.
While you are at it, don't forget to sign onto the AWAGroup of '29 Builders as there is plenty of help, discussion and good advice waiting for you there.
Hopefully we will see YOU and your new '29 transmitter next year along with those expected great band conditions!
CW key dilemma
Some time ago I purchased a Begali Key, the Contour key. I have read lots about having a good key, of how it makes sending the code an art. I have to say that from day one the Contour key and I have had a love-hate relationship! The craftsmanship of the key is next to none as are all of the Begali keys. I am not sure if it's just this key or the contour keys but for way to long when ever I use this key I send extra dots and dashes or the spacing gets screwed up. I used to think it was just me and my sloppy fist until I did more portable op's and used the Mini Palm paddle. I just never seemed to miss a beat with this paddle there was no extra anything and the code was very smooth all the time. I have contacted Begali and exchanged many emails about adjusting the key, cleaning the contacts on the key and spacing the contacts on the key. It just seems to be the same old frustration with the Contour key. When I got on the radio today for the RAC contest I started out with the Begali key and after sending some very simple but very embarrassing exchanges I switched to the Mini Palm Paddle and exchanges were sent with not one error. I would put the Begali key up for sale in a second but it has my call engraved in it. I still think nothing can be said for a good quality key but it seems the Begali Contour is just not for me.
Upcoming ’29 BK QSO Party

This Saturday night as well as the next will be the annual Bruce Kelley 1929 QSO Party, otherwise known as the '1929 BK'.
Only transmitters that are 'era-appropriate' are allowed to be used. More specifically, transmitters must employ tubes that were available in 1929 or earlier, and transmitters must be self-excited. No crystals allowed! Crystals were new and largely unaffordable for most hams back in the depression days.
1929 marked a real turning point in amateur radio as governments finally cracked-down on things such as frequency stability, out of band operations and re-alignment of call districts. In short, hams were henceforth required to behave themselves and to clean up their signals and methods of operation.

If you tune across the CW bands during the next two Saturday nights, you will have the rare opportunity to hear exactly what the bands must have sounded like back in the early '30s'.
For the most part you will hear single tube Hartley, Colpitts or TNT oscillators along with a few two-tube MOPAs thrown in. Many of them will suffer the same problems encountered by the boys of '29 ... chirp, drift, buzzy notes and frequency instability from antennas swaying in the wind.
This year, signals should be a little louder as well, since the previous power limitation of 10W input has been increased to 25W.
The MOPAs will sound much better but some surprisingly nice-sounding signals can be heard coming from properly tuned and optimised single-tube oscillators. I recall being blown away by the lovely sounding signal I heard from such a rig when first tuning into the BK activity several years ago, only to learn that it was a self-excited Hartley using 1/4" copper tubing for the oscillator tank circuit!
The '29 watering-hole on 80m will be around 3550-3580 kilocycles (be careful not to confuse this with kilohertz!) while the early afternoon to post-sunset 40m activity will be found from 7100-7125 kc. There may even be a few on the very low end of 160m. Although many of these transmitter styles were used on 20m and higher, BK rule-makers have wisely decided not to inflict these sounds on the present populace as it would likely keep the 'Official Observers' busy for several days writing pink-slips.

Building '29-Style - Part 2
Let's hope for good conditions for this event as the last few years have been adversely affected by geomagnetic storming. Poor propagation or not, I guarantee there will be plenty of '29ers busy calling 'CQ AWA' on the low bands.
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
Brian

(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 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!
