With the announcement of yet another digital mode du jour. FT4 - there are some who insist on dancing (yet again, prematurely) on CW’s grave.
As I’ve stated before, so many times ….. my personal opinion is that Amateur Radio is a big enough tent to accommodate everyone’s interests. I did digi in the 90s. Granted, it wasn’t PSK31 or the newer FT modes; but it was RTTY, PacTOR and AMTOR. These modes were quite exciting at first, but eventually grew boring to me. All the conversations that I was having seemed to consist of a bunch of key presses to release a bevy of pre-recorded macros. Spontaneous conversations took place; but they became fewer and harder to find. That’s why I drifted back to CW as my only mode of operation.
Now, that being said, I realize that my case is not the case for everyone. If digi floats your boat - then bravo! Go for it with gusto, kid! I like it when you are happy! But at the same time, please don’t look down upon me when I politely say, “Thanks, but no thanks." That doesn’t make me a fossil, a cranky old fart, a relic or a yesterday’s stale bread. It’s just that I know what I like, what I’m good at and what brings me a modicum of pleasure.
As an added note, I do not look down upon, frown upon or consider anyone less of an Amateur Radio Operator because they never learned or just plain don’t like Morse Code. Again - more power to you! Engage in whichever mode it is that makes you happy that you spent time doing it. But at the same time, don’t regard my favorite aspect of the hobby to be "old fashioned”, “irrelevant”, “useless” or “unneeded in this day and age” just because it befuddles you.
Perhaps my feelings about CW were summed up by a lot of what Dale Parfitt W4OP wrote in a post on QRP-L. I asked Dale if he would mind if I re-posted his post here. He most graciously granted me permission - here it is:
“I think the decline in CW may be more associated with the decline in civilization in general. Fewer and fewer people seem inclined to work hard and more and more seem to be embracing the concept of a welfare state, participation trophies etc. In the amateur sector, the exams have become a matter of memorization as opposed to understanding, off the shelf rigs replace homebrew and the focus of amateur radio today appears to be chatting as opposed to furthering the technical aspects of the hobby.
CW is a skill that does require work. But so enjoyable, and high speed CW is more akin to holding a conversation. I could work piles of more contacts off the moon if I did one of the digital modes. But for me, it is all about hearing these weak signals and constantly improving my station. I won’t go into the fact that some of the digital guys on the moon seem to have to communicate via the Internet to complete the digital QSO.
On HF, a nice CW ragchew, adapting to the other’s fist, using my brain and dealing with the vagaries of propagation, QRM is what it’s all about. If I want to simply send a message, I can text someone or send an email. All this has nothing to do with me being an old fart (although chronologically, I am one) . I embrace design software, love surface mount, design a lot of my rigs and build more than I operate.
YMMV,
Dale W4OP”
Thanks Dale! I guess chronologically, we’re in the same boat; but like you - for me it’s about the challenge - and constantly marveling about how my radio signal gets from Point A to Point B without the aid of anything else but my radio and antenna, my key and my brain. And I think there are quite a few of us who would still like to occupy a seat on this pleasure craft - so for those out there who think we CW devotees are nothing more than a bunch of aging, irrelevant fossils ……. pay close attention to Dale’s “YMMV”. It’s an invitation for us all to engage in what we enjoy while maintaining our mutual respect for one another.

This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be 270.0 - 319.9 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.
If you’ve been meaning to participate in CLE, then maybe this weekend is a fine time to try!
A nice challenge in this one is to hear YPM - 274, located in northwest Ontario near Pikangikum.
’ YPM’ runs just 25W into a 100’ vertical but is well-heard throughout North America. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 274.368 kHz.
Summer lightning storms may provide additional listening challenges but maybe we will get lucky.
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’ near Fargo, ND, 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:
Hello all
Our 243rd co-ordinated listening event is this weekend, covering a 50 kHz
frequency range - about three times wider than usual.
Days: Friday 26 April - Monday 29 April
Times: Start and end at midday, your LOCAL time
Range: 270.0 - 319.9 kHz (NDB signals only)
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 ‘CLE243 FINAL’ at the start of its title.
Show on EVERY line of your log:
# The Date e.g. '2019-04-26’, etc. (or just '26’)
# 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 CLE seeklists for your
part of the World, from the CLE page, http://www.ndblist.info/cle.htm
Please look out for our 'Any More Logs?’ email at about 17:00 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 08:00 UTC
next Wednesday, 1st May.
We are hoping to make all the combined results within a day or two.
Enjoy your listening
Brian and Joachim
—————————————————————–
From: Brian Keyte G3SIA ndbcle'at'gmail.com
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
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!

The Army Military Auxiliary Radio System (MARS) will host the traditional military/Amateur Radio communication tests to mark the 68th annual Armed Forces Day (AFD) on Saturday, May 11. The event is open to all radio amateurs. Armed Forces Day is May 18, but the AFD Crossband Military-Amateur Radio event traditionally takes place 1 week earlier in order to avoid conflicting with Hamvention®. Complete information, including military stations, modes, and frequencies, is available on the US Army MARS website.
“For more than 50 years, military and amateur stations have taken part in this event, which is only an exercise scenario, designed to include hobbyist and government radio operators alike,” the event announcement said. “The AFD Crossband Test is a unique opportunity to test two-way communications between military communicators and radio stations in the Amateur Radio Service, as authorized in 47 CFR 97.111. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly-controlled exercise scenario that does not impact any public or private communications.”
During the event, military stations in various locations will transmit on selected military frequencies and announce the specific ham frequencies they are monitoring.
Military stations expected to be on the air for the event include those in Arizona, Japan, Hawaii, Okinawa, Washington, DC (and elsewhere in the contiguous states), the USS Midway, the USS Yorktown, the USS Iowa, LST-325, the US Naval Academy in Annapolis, and the Newport Naval Radio Station Museum in Rhode Island. The MARSCOMM and MARSRADIO nationwide networks will have multiple stations on the air across the continental US.
An AFD message will be transmitted utilizing the Military Standard (MIL-STD) serial PSK waveform (M110) followed by MIL-STD Wide Shift FSK (850 Hz RTTY), as described in MIL-STD 188-110A/B. Technical information is available. The AFD message will also be sent in CW and RTTY, as indicated on the full schedule. Anyone wanting a QSL should complete the request form on the MARS website.

With the announcement of yet another digital mode du jour. FT4 - there are some who insist on dancing (yet again, prematurely) on CW’s grave.
As I’ve stated before, so many times ….. my personal opinion is that Amateur Radio is a big enough tent to accommodate everyone’s interests. I did digi in the 90s. Granted, it wasn’t PSK31 or the newer FT modes; but it was RTTY, PacTOR and AMTOR. These modes were quite exciting at first, but eventually grew boring to me. All the conversations that I was having seemed to consist of a bunch of key presses to release a bevy of pre-recorded macros. Spontaneous conversations took place; but they became fewer and harder to find. That’s why I drifted back to CW as my only mode of operation.
Now, that being said, I realize that my case is not the case for everyone. If digi floats your boat - then bravo! Go for it with gusto, kid! I like it when you are happy! But at the same time, please don’t look down upon me when I politely say, “Thanks, but no thanks." That doesn’t make me a fossil, a cranky old fart, a relic or a yesterday’s stale bread. It’s just that I know what I like, what I’m good at and what brings me a modicum of pleasure.
As an added note, I do not look down upon, frown upon or consider anyone less of an Amateur Radio Operator because they never learned or just plain don’t like Morse Code. Again - more power to you! Engage in whichever mode it is that makes you happy that you spent time doing it. But at the same time, don’t regard my favorite aspect of the hobby to be "old fashioned”, “irrelevant”, “useless” or “unneeded in this day and age” just because it befuddles you.
Perhaps my feelings about CW were summed up by a lot of what Dale Parfitt W4OP wrote in a post on QRP-L. I asked Dale if he would mind if I re-posted his post here. He most graciously granted me permission - here it is:
“I think the decline in CW may be more associated with the decline in civilization in general. Fewer and fewer people seem inclined to work hard and more and more seem to be embracing the concept of a welfare state, participation trophies etc. In the amateur sector, the exams have become a matter of memorization as opposed to understanding, off the shelf rigs replace homebrew and the focus of amateur radio today appears to be chatting as opposed to furthering the technical aspects of the hobby.
CW is a skill that does require work. But so enjoyable, and high speed CW is more akin to holding a conversation. I could work piles of more contacts off the moon if I did one of the digital modes. But for me, it is all about hearing these weak signals and constantly improving my station. I won’t go into the fact that some of the digital guys on the moon seem to have to communicate via the Internet to complete the digital QSO.
On HF, a nice CW ragchew, adapting to the other’s fist, using my brain and dealing with the vagaries of propagation, QRM is what it’s all about. If I want to simply send a message, I can text someone or send an email. All this has nothing to do with me being an old fart (although chronologically, I am one) . I embrace design software, love surface mount, design a lot of my rigs and build more than I operate.
YMMV,
Dale W4OP”
Thanks Dale! I guess chronologically, we’re in the same boat; but like you - for me it’s about the challenge - and constantly marveling about how my radio signal gets from Point A to Point B without the aid of anything else but my radio and antenna, my key and my brain. And I think there are quite a few of us who would still like to occupy a seat on this pleasure craft - so for those out there who think we CW devotees are nothing more than a bunch of aging, irrelevant fossils ……. pay close attention to Dale’s “YMMV”. It’s an invitation for us all to engage in what we enjoy while maintaining our mutual respect for one another.

HANS JOHNSON ? APR 23, 2019
SYDNEY — Radio Australia shortwave services may be dead, but the medium is alive and well on the continent.
Reach Beyond Australia is on shortwave, but with its Christian programming largely in foreign languages, it really isn’t seen as representing Australia on the shortwaves. But there are other private Australian stations that are broadcasting and more are planned.
And while these stations are not a replacement for Radio Australia’s international transmissions or the defunct (for the moment) Australian Broadcasting Corp. domestic service, they do have various goals and share certain characteristics.[…]
4KZ is a shortwave relay of an Innisfail, Queensland, medium-wave station with the same call sign. It is part of the NQ Radio network. 4KZ plays a variety of music and is heavily involved in the community. The shortwave serves remote areas of north Queensland. “We are planning a 90-or 120-meter service for evenings local time, from station 4AM in Mareeba,” explained Al Kirton, NQ Radio’s general manager.
Unique Radio has been on three years and currently broadcasts from Gunnedah in New South Wales. Its owner, Tim Gaylor, has a background in community radio. “We like a station to inform people about alternative subject matters not currently on mainstream media,” he said. Unique Radio also plans to add a night frequency in the 90-meter band.
There are also future stations in the works from New South Wales.[…]

Radio engineer Moshe Rubin transmits the special broadcast during the opening of the Palestine Broadcasting Service, Ramallah, March 30, 1936. Source: Library of Congress Prints and Photographs Division Washington, via RFI
Many thanks to SWLing Post contributor, Alan Roe, who writes:
There is an interesting article/podcast by R France Int
entitled “The power of radio during British-mandated Palestine”.
“On 30 March 1936, the British High Commissioner of Palestine, Arthur
Wauchope, inaugurated the Palestinian Broadcasting Service, the PBS. It
was the second broadcaster to be established in the Middle East, after
Radio Cairo in 1934, and featured programmes in Arabic, Hebrew and English.
It covered the region of Palestine, Jordan, Syria and Lebanon, as well
as parts of Egypt. The new transmitter was in Ramallah and the
broadcasting offices were in Jerusalem.”

NJARC Members (Source: NJARC)
Many thanks to SWLing Post contributor, Dennis Dura, who recently shared this video where “Radio Wild” asks his viewers to subscribe to the New Jersey Antique Radio Club (NJARC) YouTube channel.
Evidently, the NJARC has been posting live video feeds of their meetings and events for quite some time, but recently YouTube changed their policy and now requires a minimum of 1,000 subscribers for live feeds. At time of posting, my subscription brought their number to 700–they need at least 300 more.
If you’d like to support the NJARC (and learn a thing or two about radio restoration–!), consider subscribing to their channel.
