Hunting For NDBs In CLE254
Once again it's a CLE weekend.
During these stressful times, the CLE might hopefully provide some peaceful relief for you.
'CLE's are 'Co-ordinated Listening Events, and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.
This time the hunting ground is the 20 slice from 400.0 - 419.9 kHz. kHz
A good target for this one is MOG (404kHz) in Montague, California, up near the border with Oregon. It gets out very well and has been logged from Finland to Hawaii. Its been on-and-off of late so maybe you can catch it while it's on again!
Listen for MOG's upper sideband on 405.027kHz with your receiver in the CW mode.
From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:
Hello all,
Our 254th Coordinated Listening Event starts on Friday.
This frequency range is not packed with signals for any of us, but if conditions are OK there should be some nice surprises.
Do join in, whether you have days to spare, or only an hour or so over the weekend. Staying at home seems to be essential advice for most of us at present - this could be a great way of spending time there!
Days: Friday 27 March - Monday 30 March 2020
Times: Start and end at midday your LOCAL time
(Many of us will be changing our home clocks this weekend -
however UTC time continues unaffected)
Range: 400 - 419.9 kHz
Please log all the NDBs that you can identify with nominal (listed) frequencies in the range - it includes 400 kHz, but not 420 kHz - plus any UNIDs that you come across there.
Send your final log to the List (no attachments please and ideally in a plain text email) with ‘FINAL CLE254’ in its title.
Show on each line:
# The Date (e.g. '2020-03-27', etc., or just '27' )
# The Time in UTC (the day 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.
As always, of course, tell us your own location and brief details of the equipment that you were using during the Event.
We will send the usual 'Any More Logs?' email at about 19:00 UTC on Tuesday so that you can check that your log has been found OK.
Do make sure that your log has arrived on the List by 08:00 UTC on Wednesday 1 April at the very latest.
We hope to complete making the combined results within a day or two.
You can find full details about current and past CLEs from the CLE page http://www.ndblist.info/cle.htm It includes access to CLE254 seeklists for your part of the World, prepared from the previous loggings in Rxx. (Thanks, Martin and Alan, for your help with that)
Good listening
- enjoy the CLE and do take care of yourself and your family.
Brian and Joachim

From: Brian Keyte G3SIA ndbcle'at'gmail.com
Location: Surrey, SE England (CLE coordinator)
-----------------------------------------------------------------
(If you would like to listen remotely you could use any one remote
receiver for your loggings, stating its 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)
- 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
The NDB List 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 NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers.
Remember - 'First-time' logs are always VERY welcome!
Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.
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!
Here Comes The Novice Rig Roundup (NRR) 2020!
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.
Once again the bands will be alive with the sounds of Heath AT-1s, DX-20s, DX-35s, DX-40s and DX-60s, Johnson Adventurers, Eico 720s, Drake 2NTs, Knight T-50s and T-60s, Ameco AC-1s and of course, an endless variety of lovingly-constructed homebrew delights and ... a full week plus two weekends to celebrate the 'good old radio days' of their teen years, as many of us remember them.
The dates to remember are 0000 UTC March 7 to 2359 UTC March 16 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, but many transcon contacts were made during last year's event thanks to some well-timed solar activity! 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. If you used the logger last year, you will have to set it up again for this year as the old system has been changed.
Stations may run either crystal-control or VFO or can switch between either method ... the online logger will keep track and score things appropriately.
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 Group, often the source of much valuable discussion but there is a now HUGE group of great NRR chat and activity now on Facebook's NRR Group here. I avoided Facebook for many years and have now discovered that it is an excellent forum for real time chat and information exchange ... one can still choose to maintain a very low profile and avoid unwanted interaction if set up correctly.
In 2017 I ran my homebrew Longfeller in the (now eliminated) QRP category, and had a ton of fun. You can read about it here. Last year, I refurbished a nice Drake 2NT that had been gathering dust in the basement for over 25 years and ran it during the 2018 NRR. You can read about my activity and some of the rigs encountered during last year's fun here.
If you have access to the web while operating, be sure to bookmark and check into 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!
'CQ'ers should always remember to tune up and down the watering hole for replies from other NRR stations that may be crystal controlled and not able to answer you on your own frequency!! This is extremely important and a real reminder of what was 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.
Need more inspiration? ... here's a summary of my own experience of the 2018 NRR:
***********************
The NRR once again provided many notable highlights over the nine day event.
Almost topping the list was just experiencing the variety of old classics and hearing how well almost all of them sounded. Numerous Knight T-60s, Drake 2NTs, Heath DX-40s, Johnson Adventurers and Eico 720s, along with a nice variety of homebrew MOPAs and one-tube power oscillators graced the nightly airwaves. These oft-forgotten shelf-queens always seem to develop super-powers, far beyond their expectations, when the NRR rolls around!
I was really surprised to work so many T-60s, a small and inexpensive 60 watt transmitter kit from 1962 using a popular 6DQ6 television sweep tube ... one never expected to achieve such RF greatness! I was very impressed with every one that I heard.
What radio-struck pre-Novice teen, dreaming about getting on the air, could resist a clever ad like this.
Scott, KA9P's 80m T-60 signal sounded as sweet as it looks in his 2018 setup, paired with his Heathkit HR-10B inhaler.

Right up there with the plethora of T-60s was the Drake 2NT, another great sounding radio and also my choice for this year's event. My summer refurbishing project, described here, proved a worthy companion, although my much-treasured VF-1 VFO's short term drift probably had my 2NT getting red in the face whenever I took her off of crystal control to scurry around the band, seeking out the CQ'ers. I've had a love-hate relationship with the VF-1 ever since buying my first one back in '63!

Yet another 2NT packed a powerful punch from West Virginia, keyed by Dave, W3NP, when we exchanged 579 reports on 40m, 45 minutes before sunset.
W3NP - 2018 NRR setup |
I made three contacts on 15m this year: W5IQS in Texas, K2YWE in Maryland and WN4NRR in Florida, whose S9 reply to my 'CQ NRR' just about took my head off ... what a nice surprise to hear the booming signal from Bry's 2NT powerhouse. Dan, K2YWE, was no slouch either, as his Globe Scout was music to my ears when his signal quickly rose out of the noise just long enough to make the coast-to-coast journey. If the predictions for future solar cycles become reality, there may be many more NRRs before we experience the magic of 15m once again.
K2YWE's Globe Scout and Adventurer were worked on all three bands! |
My NRR exchanges with George, N3GJ (KA3JWJ) in Pennsylvania, truly demonstrated just how well the low bands were performing. More than an hour before my local sunset, I responded to his 569 40m 'CQ NRR' only to learn that his signal, now reaching a solid 579, was coming from an original Ameco AC-1! This one-tube crystal-controlled power oscillator has, over the years, reached Holy Grail status among many amateurs. Originals are guarded like precious jewels and handed down from father to son ... or in George's case, from uncle to nephew!
N3GJ and his all powerful original AC-1 |
Heathkits were plentiful too, with the DX-60 seeming to be the rig of choice, often paired with the matching HG-10 VFO. Both Mark, VA7MM and Gary, W8PU, packed a wallop with these fine examples.
VA7MM - 2018 NRR set-up |
W8PU - 2018 NRR set-up |
But it wasn't just DX-60s representing Benton Harbor engineering in the NRR. All of these neat old Heaths made it out to the west coast, sometimes on both 40 and 80. KN8RHM's (Rick) HW-16 made it here on 40m with a solid signal almost every night, while KE4OH (Steve) sported a modernized DX-20 in the form of Heath's HX-11. Steve even received the highly-treasured 'OO' report for his NRR chirp ... good job!

Rich, WN7NRR / AG5M operating in nearby Washington state put some of his 44 crystals to work with his HW-16 ... that's some collection!

Howie, WB2AWQ in Reno, was using his homebrew pair of 807s, driven with a Millen 90700 swing-arm VFO from 1945. Most shacks worldwide, including the Novices, found plenty of use for the 807 as they were dirt-cheap in the post war surplus market. The filament has a beautiful illumination and if a bit gassy as most are by now, emit a wonderous blue glow with each press of the key.

K4IBZ's 10 watter |

I finished up the NRR with 123 contacts, a lot better than last year's event when I was running the Longfeller at 5 watts.
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 2020 NRR!
Barn Door Wide! Hunting For NDBs In CLE253
This weekend's upcoming CLE event will be the "Barn Door" listening event.
Participants are required to use receivers without the usual narrow filters. Some of the older tube radios can do this easily as can most homebrew receivers ... especially the regens!
If you've never listened to the NDB band with a wide bandwidth, it is a fascinating experience! If conditions are normal, you can typically hear a half dozen or more signals, all at various pitches, vying for your attention. It's almost as if you have plunked yourself down in the middle of the NDB forest of signals, and they are coming at you from all directions.
Many choose to use one of their homebrew receivers for this event, often as simple as a '1AD' or a '1 Active Device' circuit.
From organizer Brian Keyte:
Times: Start at Midday on Friday 21st, your LOCAL time
End at Midday on Monday 24th, your LOCAL time
Frequencies: Centred on 360 kHz (see below)
NDBs: NOT MORE than 100 'normal' NDBs including any UNIDs
(That is not intended to be a target to reach)
Whichever you choose, use the same receiver throughout the 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
The NDB List 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 NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers.
Remember - 'First-time' logs are always VERY welcome!
Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.
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!
Contest Morse Code, Computers, and an Icom Rig
This past weekend (third full weekend in February, February 15-16, 2020) is the ARRL International CW Contest (ARRL DX CW link: http://www.arrl.org/arrl-dx ). This is interesting to my study of radio signal propagation as a columnist and as an amateur radio operator because of the contest objective: “To encourage W/VE stations to expand knowledge of DX propagation on the HF and MF bands…” This contest is a good way to get a feel for current propagation–though there are caveats.
Speaking of Morse code and the CW mode on our amateur bands: those of you using CW during contests, do you send by hand or by computer? Do you copy the code by head, or do you use a computer for decoding?
In most contests like the ARRL DX CW contest, I copy by ear, and send mostly by rig keyer. If needed, I use a single paddle key with the Icom rig’s internal keyer to answer unique questions and so on.
Below is a quick demo of using the internal Morse code keyer in my Icom IC-7610 transceiver.
V47T, in the Saint Kitts and Nevis Island in the Caribbean, is calling CQ TEST in the ARRL DX CW contest.
Using the programmable virtual buttons, in which I programmed my callsign, NW7US, and other info, I answer and make a complete contest QSO.
In activity like the Straight Key Century Club (SKCC – https://SKCCGroup.com) K3Y special event, it is all manual. I send my Morse code using a WWII Navy Flameproof Signal Key, and decode with my ears. It is contextual for me.
[embedyt] https://www.youtube.com/watch?v=vm8UJst6umA[/embedyt]
How do you do contesting Morse code? Bonus question: How do you do logging while doing contest operation?

The G3LEK key that turned up in Chile?
Of course being a ships ex Radio Operator, Len was also a very proficient CW operator, and this never left him throughout his Amateur radio years.
A few days ago Martin contacted me. who now is now 2E0LEK and following in his late Dad's footsteps with the hobby.
WOW !! I am amazed .... A British engineer has contacted me through the RSGB regarding my late Fathers CW Morse Key, and it is in Santiago Chile. I have been wondering where it had gone, and now I know.
Martin said the chap who has got the old key is Simon, and he said it can be a bit iffy .... His XYL is Angie who bought it from an antiques dealer in Santiago. The dealer found it in a secondhand market in the city, called Persa Bio-Bio……Apparantly a fascinating place to visit if you ever get the chance (but don’t carry any valuables and be very careful).
Ref:https://www.fleamapket.com/listing/persa-bio-bio/
So Martin is now on the chase to find out how the key arrived in Chile? I know when Len left the old bungalow where he once lived, he cleared the garage out and filled up his VW camper van and took most of the ex MOD equipment to a place called Thackers at Cheslyn Hay (long time gone), Thackers were scrap dealers and breakers in ex ministry gear.
Leave comment below if you have come across the G3LEK CW key on it's travels. Martin would like to hear from anyone, who might know something.
.
Taking steps forward.
He highlights 12 common problems and how to overcome them so please if you want to improve your code read over the document and see any issues come to light.
Of the 12 common problems, I was able to identify with 6 and they were:
1. Anticipating what is being sent. This is done when you copy with a pencil and paper and copy one letter at a time and not by the rhythm of a word. For example when you hear someone calling CQ most of us don't write down the letter C and Q. We know the rhythm of CQ and know the word. I have to learn the rhythm of CW and not writing letters. Learn the code as a language.
2. The inability to copy behind. This was a new one for me I never really had heard of it. You hear one or two letters and let them float in your head once you hear the 3rd letter you write down the first and second letters. In the past, if this happened to me I would panic as I figured I was getting behind in the copying.
3. Unable to increase my speed. I hit a plateau and become frustrated. The suggestion is to increase the code you are receiving by about 2 wpm above your plateau speed.
4. Lack of confidence. This for sure has been an issue with me I have found once a contact gets rolling I can get lost because of some of the issues mentioned above. Once this happens I just want to pass along 73 and TU and end the QSO.
5. Not able to hear complete words. This is just done with the practice of copying complete words and not each letter.
6. Writing each letter as it is heard. This for sure is an issue with me. I find as the speed increases I just get lost as I can't write things down fast enough. I have tried using a keyboard as I can type very fast but I have found that at a certain speed the letters are coming at you so fast you get lost between hearing the letter and then transposing it to the keyboard key.
The bottom line from what I have been reading is I have to learn how to put the pencil and paper away and copy in my heard with just writing down selective information. I really believe it's retraining your brain on how CW is understood. I relate it too when I first was learning to type and when I was to type "the" I would type "t" "h" "e" but now I don't even think about it.......well it's more like I think it and it appears on paper. I am not even thinking of were my fingers are going on the keyboard. I have to train my brain this way regarding morse code.
The CWops is a very popular program and spaces fill up fast and at this point in time, the class enrollment is for April/May or Sept/Oct. I am trying to see if the April/May works out for me. Until I am accepted into either time slot for the class I wanted to work on my code. So I am going to work on the above issues I have mentioned.
