Highlights of Solar and Geomagnetic Activity 18 - 24 March 2024

Solar activity during the week reached high levels. The largest flare was an X1.1/ 2F at 23/0133 UTC. Region 3614 (N17, L=224, Dso-B/210 on 23 Mar) produced the flare which appeared along a filanment channel to the north of the spot group. A 240 SFU 10cm radio burst and Type II sweep (791 km/s) were observed. The flare was also accompanied by an EUV wave, dimming and post-eruptive arcades visible in GOES SUVI 195 Angstrom imagery. An asymmetric halo cme was first visible in SOHO/LASCO C2 imagery at 23/0048 UTC. Plane of sky measurments averaged from C2 and C3 suggested the CME was moving at 1492 km/s. While Region 3614 produced the largest flare of the week, Region 3615 (S13, L-215, Fkc-BGD/810 on 24 March) was the most prolific. It produced 27 M-class flares during the week, three of which were greater than M5 (R2). The largest was an
M7.4, 3B on 20/0736 UTC. 

The X1.1 and CME described above triggered a 10 MeV proton event. The 10 MeV flux began rising at 23/0400 UTC, crossed the 10 pfu (S1) threshold at 23/0815 UTC and the 100 pfu (S2) threshold at 23/1405 UTC. The event peaked on 23/1820 UTC at 956 pfu. A second peak of 687 pfu was observed at 24/1230 UTC as the CME described earlier approached. 

The greater than 2 MeV electron flux at geosynchronous orbit ranged from normal to moderate levels throughout the week. 

Four distinct geomagnetic storms ocurred during the week. The first was associated with a CME arrival at 21/0225 UTC. Bz dipped southward to -12 nt and, and a couple of periods of prolonged southward Bz led to three synoptic periods of minor (G1) geomagnetic storm conditions between 21/1200-2100 UTC. The second even began on 22/2320 UTC Bz shifted southward around 23/0100 UTC and remained there for about 7 hours. This gave rise to two periods of minor (G1) geomagnetic storm conditions between 23/0300-0900 UTC. 

This activity was most likely a CIR, in advance of a negative polarity coronal hole, based on the density increase and rotation of the Phi angle .Solar wind speed and temperature began rising at the end of the storm activity, suggesting the high-speed stream had become geoeffective. The third storm began with the 23/1800 UTC UTC synoptic period (Kp=5-, G1), peaked during the 2100-0000 UTC
synoptic period, reaching Kp=6- (G2), and returned to G1 conditions for the final period from 24/0000 UTC to 24/0300 UTC. The final storm began with the arrival of the CME described in the first paragraph. The interplanetary shock arrived at L1 at 24/1411 UTC and a sudden impulse (377 nT at Meanook Observatory) was detected at 24/1437 UTC. 

Solar wind speed jumped from the 500-550 km/s high speed stream values to approximately 800 km/s and remained elevated. Bz dipped southward to -27 nT at 24/1510 UTC. Kp ranged from 6+ (G2) moderate storm conditions to 8o (G4) sever conditions between 24/1200-2100 UTC. The severe synoptic period was from 24/1500-1800 UTC. The magnetic cloud appears to have arrived around 24/1826 UTC distinguised by a slow rotation of the Phi angle. Earth was still within the magnetic cloud at the end of this reporting period. 

Forecast of Solar and Geomagnetic Activity 25 March - 20 April 2024

The threat of high solar activity remains throughout the coming week. Region 3615 (Fkc-BGD) is expected to remain on the visible disk until March 29th-30th. The departure of Region 3615 is anticipated to bring a period of low solar activity with a lingering chance for M flares. Regions 3614 and 3615 are expected to return on April 11th, increasing the potential for moderate to high activity. 

Along with the high solar activity, there is a chance for another proton event at geosynchronous orbit, with the greatest threat from Region 3615 until it departs. The threat will decrease until the region returns on April 11th. 

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels during the forecast period. The high levels are anticipated between March 28th-31st, and again from 6-8 April in the wake of coronal holes. 

The beginning of the forecast period is expected to see strong (G3) geomagnetic conditions declining to mostly quiet conditions after March 26th. Levels will increase to potentially minor (G1) levels with the influence of a coronal hole high speed stream on April 3rd-5th. High speed streams on April 9th-11th and 19th-20th are expected to bring less than minor (G1) storm conditions. The threat of more CMEs and subsequent storms associated with Regions 3614 and 3615, or with new regions that emerge, remains.

FastRadioBurst 23 and WSFR-Lost Island Radio slated for broadcasts

 It’s another week gone again and I’m FastRadioBurst 23 from the Imaginary Stations crew letting you know about this week’s shows. The first  broadcast is to Europe via Shortwave Gold on Sunday 24th March 2024 at 1000/1400 hrs UTC on 6160 kHz and then at 2100 UTC on 3975 kHz. This time we turn the clocks back for a bit of time anomaly broadcasting with KTAB. We’re talking old time business with some real oldies but goodies. It’s all about the power of the wireless. Tune in and go way back into time with us.

On Thursday 28th March via WRMI we have a dreamy paradise lost of a show called WSFR – Lost Island Radio at 0200 UTC on 9395 kHz. Get those bags packed and that passport at the ready as you are going to be transported to a dreamy destination far far away.

Don’t worry, you won’t be marooned as we will bring you back safely to your armchair after the hour concludes. Tune into WRMI at the allotted time (Do give yourself enough time to check in and settle down of course) for some paradise island classics.

Why Is Shortwave Only “the Radio of Last Resort”?


Its powerful new capabilities remain largely unexplored


The author is sales and business development manager for Ampegon Power Electronics AG.

My first car, a 1984 vintage, had a shortwave radio receiver, but I didn’t bother using it. I was young while it was old and therefore unworthy of my attention. Besides, the signal it received was mostly odd-sounding talk-radio that changed tone as I accelerated. Something to do with unscreened sparkplugs? Whatever they were. Instead, I had a huge selection of pop music available to me on the FM bands, and big plans to retrofit new dash-mounted CD player technology (which never worked)!

Shortwave’s unique properties
The big draw of shortwave is the ability to broadcast to the other side of the world. Shortwave frequencies reflect off the ionosphere, offering long-range capabilities not possible with FM and MW propagation. With a high-power transmitter and appropriate antenna, shortwave broadcasters can provide national, continental or even inter-continental coverage from a single location. 

BBC announces Radio 4 changes on mediumwave


BBC Reception has revised their statement below - R4 programme changes take effect from 1st April. 

MW frequencies stop carrying R4 programmes from 15th April still [will MW channels carry a retuning announcement after 15th April or just be switched off?]. 

On 20/03/2024 22:23, Alan Pennington via wrote:
BBC Reception website has now added this post this evening about Radio 4 changes. Interestingly, the final sentence states:

"Effective 15th April, Radio 4 will no longer be available on medium wave. Medium wave listeners will need to retune their radio to Radio 4 on FM or DAB, or listen via smart speaker, BBC Sounds or digital television."
BBC R4 medium wave transmitters are as follows:
603 kHz Newcastle upon Tyne
720 kHz Londonderry
720 kHz London (Crystal Palace)
720 kHz Lisnagarvey
756 kHz Redruth
774 kHz Enniskillen

Highlights of Solar and Geomagnetic Activity
11 - 17 March 2024

Solar activity ranged from low to moderate levels. Moderate levels were reached on 14 Mar due to an M1.0/sf flare at 14/0604 UTC from Region 3599 (S12, L=065, class/area Dao/230 on 12 Mar). On 16 Mar, Moderate levels were once again seen as an M3.5 and an M1.1 occurred at 16/1635 UTC and 16/2155 UTC from a region just beyond the SE limb. Region 3599 was also responsible for a series of CMEs just beyond the SW limb which occurred at 15/0210 UTC and 15/0328 UTC. Modelling of the event indicated no Earth-directed component, however, an associated minor solar radiation storm (S1) was observed. Other activity included an approximate 35 degree filament channel eruption centered near S28W25 beginning at 17/0100 UTC. Two subsequent CMEs were observed in SOHO/LASCO C2 imagery off the SSE and SW limbs at 17/0312 UTC and 17/0336 UTC, respectively. Modelling indicated possible glancing blows late on 20 Mar to early on 21 Mar. 

A greater than 10 MeV proton event above the 10 pfu (S1/Minor) threshold as a result of activity from Region 3599 beyond the SW limb early on 15 Mar. The event began at 15/2050 UTC, reached a peak flux of 16.7 pfu at 16/0635 UTC, and ended at 16/1505 UTC. 

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 11 Mar due to CH HSS influence. A peak of 1,420 pfu was observed at 11/1605 UTC. 

Geomagnetic field activity ranged from quiet to active levels. Solar wind speed decreased on 11 Mar as weak negative polarity CH HSS influence diminished. A solar sector boundary crossing was observed midday on 11 Mar followed by another mild increase in solar wind speed and total field on 12-13 Mar. Solar wind speed reached a maximum around 484 km/s by 14/1350 UTC with total field near 9 nT early on 14 Mar due to positive polarity CH HSS influence. The geomagnetic field responded with unsettled periods on 12 and 14 Mar and an isolated active period early on 15 Mar. Solar wind speed slowly decreased around 290 km/s with total field values below 5 nT by the end of the period. 

Forecast of Solar and Geomagnetic Activity 18 March - 13 April 2024

There is a chance for moderate (R1-R2/Minor-Moderate) levels through 31 Mar, mainly due to the flare potential of Region 3614 (N16, L=223, class/area Hax/080 on 17 Mar) and an unnumbered region rotating onto the SE limb. Low levels with a slight chance of
M-class flares are likely on 01-13 Apr. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 07-08 Apr due to recurrent CH HSS influence. 

Geomagnetic field activity is expected to be at unsettled to active levels, with G1 (Minor) storming likely, on 20-21 Mar due to activity from the 17 Mar CMEs. Unsettled levels are expected on 28-29 Mar, 03-05 Apr, and 09-11 Apr due to recurrent CH HSS

Uncle Bill's Melting Pot announces programming shift


Teak Publishing wishes 'Uncle Bill'  the very best on his broadcasting project.

Dear radio friends, 
Our last broadcast on WBCQ The Planet 7490 kHz on the shortwave bands will be Sunday, March 17 from 6-7pm EST (2200-2300 UTC). 

The program will also stream on (it is livestream ONLY, not available on demand). 
This will touch on St. Patrick's Day, Daylight Savings Time, spring training in US baseball, and some goodies from around the world..

In April the show will be migrating to Europe. More details in the coming weeks. This is not an easy decision - we were born on WBCQ, and it was very good to us over the years, but there isn't enough financial support to do both the Americas and Europe, and European audiences have been more engaged on the whole than North American shortwave listeners over the years.  If it can be only one, Europe makes sense.  
(Uncle Bill)

New TWR Website Builds Connections With Latin Americans


TWR’s ministry in Latin America has launched a new website to build community and collaboration among Christian organizations and boost the distribution of gospel media content throughout the region. was created by and for TWR’s ministry to Latin America and the Caribbean, one of four major global regions where the ministry proclaims the gospel via radio, video, and multiple digital media. RTM stands for Radio Trans Mundial, which is the Spanish and Portuguese equivalent of Trans World Radio.

"The digital world has created a new environment with its own language and logic," said Esteban Larrosa, RTM vice president for Latin America and the Caribbean. "It opens up the opportunity for us to complement radio broadcasting with other possibilities of interaction, deepening the relationship with our audience and with the network of stations that use RTM's multimedia content production every day."

Latin America and the Caribbean are home to more than 600 million Spanish and Portuguese speakers, and the international TWR ministry has national partners in 17 of the region’s countries. TWR and its partners share the gospel via the hemisphere’s most powerful AM transmitter on the island of Bonaire, another substantial though less-powerful AM transmitter in Uruguay, many local stations, and various digital platforms.

RTM leaders decided to build a customized website to help achieve several key objectives, and the effort was led by regional International Director Annabel Torrealba and Communications Director Maralina Alfonso. They want to bring social-media users, churches and other Christian organizations to a single site where the ministry can be introduced and content promoted. That includes more than 72 Spanish-language programs produced by TWR and its media partners. They also seek to inform local radio stations – over 600 of which already carry RTM Spanish programs – about the abundant programming available for broadcast.

Another desire is to share articles addressing topics of concern for Latin American audiences. New articles titled “The Silent Enemy,” by Larrosa, and “What Every Man Should Know,” by Carlos Cardenas of Colombia, were posted at the launch. Alfonso said other features are also planned and will debut on the site when ready. The RTM staff believe will enable them to better interact with and keep informed Latin Americans like this listener in Cuba.

“I listen to your program through Radio Trans Mundial from Bonaire, and it is a great blessing for me,” the listener wrote in an email. “… Unfortunately, here in Cuba there are no Christian radio stations. For this reason and much more, it is very good for the Cuban people to have the great privilege of being able to count on you. Your program nourishes my life.”

Although the new site is aimed mainly at Spanish speakers outside the United States, lively pages geared toward Hispanics in the U.S. are accessible at or via the Español selection under the Regions tab on

Wavescan looks at the use of Callsigns, Part 1 and 2

 Special thanks to Ray Robinson and Jeff White for sharing the Wavescan script of Part 1 and 2 on Callsigns 

Callsigns, Part 1 - Mixed Letters and Numbers

Jeff: What is the origin for the system of radio station callsigns that are in use throughout the world to this day? How come some stations are identified with just alphabetic letters only? And other stations are identified with both numbers and letters?  Ray Robinson has been digging into this history, and has more from Los Angeles.

Ray: Thanks, Jeff.  Way back 180 years ago, in the early days of telegraphy by Morse Code, the operators at each station that was connected by telegraph wire used a simple abbreviation to identify the sending station, rather than laboriously spelling out the location name. The usage of many abbreviations enabled the operators to send their messages more quickly.

Some 50 years later, when wireless stations were erected for the transmission of messages by Morse Code, the same procedures were followed; that is, the usage of as many abbreviations as possible, including an abbreviation for the sending location. Some abbreviations for the locations of very early wireless stations were quite logical, such as for example:-

CC Cape Cod Massachusetts USA
FL Eiffel Tower Paris France
SF San Francisco California USA
GB Glace Bay Nova Scotia Canada

However, due to the number of wireless stations proliferating throughout the world, most of the abbreviations in use for the locations of wireless stations bore no resemblance to the actual location. For example:-
EX Los Angeles California USA
SN Cordova Alaska
UA Nantes France
DF Santa Barbara California USA
Another DF Vancouver British Columbia Canada

In an endeavor to regulate this confusing system of random choices, an international wireless convention was held in Berlin in 1906.  This was the second international convention in Berlin that addressed the need for the regularization of the newly developing wireless scene that began with the work of the famous Italian, Guglielmo Marconi.

At this 1906 wireless convention, a system of alphabetic designations was allocated for all countries throughout the world.  For example, transmitter callsigns beginning with:-
G were allocated to Great Britain
V British colonies
F France & French colonies
I Italy
J Japan

There was a third international wireless convention held in London, England on April 23, 1913.  Even though this event was staged mainly to address the wireless scene in Europe, delegates from the United States also attended and participated.

One of the important matters looked at on this occasion was the identification of amateur and experimental wireless stations which were beginning to proliferate in many countries.  However, because the coverage area from these lower-powered operations was considered to be quite local, it was decided to implement a different system of identification.

The decision reached was to introduce a system of numbers and letters, with the initial number indicating the geographic location. Single numbers were chosen for each of the participating countries in Europe, as follows:-

Luxembourg was assigned number 1
United Kingdom was assigned numbers 2, 5 & 6
Germany was assigned number 4
Denmark number 7
France number 8
Holland number 0

The major determining factor at the 1913 convention was that the initial digit number in a callsign indicated a specific geographic area. At this stage in Europe, the initial number indicated a specific country.

Likewise, when the American delegates returned home, the government authorities decided to implement a similar system in the United States using the numbers 1 through 9, with each number indicating a specific cluster of states.  North of the border in Canada, they soon implemented a similar system, with an initial digit assigned to each province.

This same numeric scheme was also implemented in the South Pacific.  Australia chose the numbers 2 through 9, indicating each separate state, as well as nearby Papua & New Guinea.  New Zealand chose the numbers 1 through 4, indicating major geographic areas in the twin island country, beginning with 1 at the top of the North Island and ending with 4 at the bottom of the South Island.

When radio broadcasting was introduced in England, this same numeric system was implemented according to the action taken at the Third International Convention in London in 1913. The first radio broadcasting station was 2MT Writtle, a Marconi experimental station launched in Essex, north east of London, in February 1922; and next on the list came 2LO London, three months later.

However, in the list of the 22 introductory radio broadcasting stations in England from 1922 to 1925, there seems to be little apparent logic in the choice of the initial digit, whether it was 2 or 5 or 6. Likewise, there was little apparent logic in the two letters of the alphabet that made up the remainder of the callsign.

Obvious callsigns in Great Britain during this era were 2BE Belfast in Northern Ireland; 5WA in Wales, at Cardiff; and 6ST in Stoke-on-Trent.  However, in view of the fact that so many of the other callsigns in England during this early era seemed to be almost randomly assigned, it is probably the case that calls were chosen that were not already taken up by amateur radio operators.  Even to this day, all amateur radio stations throughout the world are identified according to a mixture of letters and numbers.  The initial alphabetic digits indicate the country, and the following numeric digits usually indicate regions within that country.

Likewise with the countries that have retained a similar system for the callsigns of radio broadcasting stations.  In Australia, the initial number still indicates the state, and the following two letters identify the station, and quite often, also the location. For example:-

2BH is located in Broken Hill New South Wales,
4TI Thursday Island Queensland
6XM Exmouth Western Australia
8AL Alice Springs Northern Territory

Next week here in Wavescan, we will take a further look at the interesting story regarding the usage of radio callsigns throughout the world; and on this next occasion, it will be the interesting story specifically of shortwave callsigns.

Callsigns, Part 2 - Shortwave

Jeff: Last week in here in Wavescan, Ray Robinson introduced the topic of Call Signs, and how specifically mixed calls containing a combination of numbers and letters came to be assigned.  This week he delves further, specifically into the history of shortwave callsigns.  Ray?

Ray: Thanks, Jeff.  I’ve been interested in all things radio throughout my teen and adult years, and always assumed that call signs in those countries which used them for broadcast stations were assigned to the stations themselves.  However, I was surprised to learn that just before the middle of the last century, the government licensing authority in the United States issued a decree stating that every shortwave transmitter should be licensed with its own separate callsign.  And thus, a station with more than one transmitter would have to have more than one callsign.

But even that was rather loosely implemented.  As an example, a list of shortwave channels for the RCA station located at Bolinas in California was published in the monthly magazine, Radio News, for August 1935.  This list shows almost thirty different three letter callsigns ranging from KEB to KWE; but, there is one callsign per channel frequency used, not one callsign per transmitter.  It appears that, in practice, if a transmitter changed frequency, it also changed callsign.

This same 1935 list shows more than twenty callsigns for the large RCA communication station on the east coast, at Rocky Point on Long Island, New York.  There, the three letter callsigns run from WAJ down through WQP, though not all of these letters were taken up by the station.  Interestingly, when this RCA station at Rocky Point was on the air with radio broadcast programming, an experimental callsign, W2XBJ was used, regardless of transmitter and regardless of frequency.

However, it is true; most of the shortwave stations in the United States that were on the air with broadcast programming during the 1930’s & 1940’s were identified with just one callsign per transmitter.  Examples of this form of callsign usage would be:-
W8XK Pittsburgh Pennsylvania
WRUW & WRUL Scituate Massachusetts
KGEI & KGEX Belmont California
W4XB Miami Beach Florida
W2XAD & W2XAF Schenectady New York

Going northwards into Canada, one authority informs us that the basic callsign for the large RCI shortwave station that used to be located at Sackville, New Brunswick was CKCX.  However, during the earlier part of its history, this shortwave station was on the air with one callsign per each shortwave channel.  The CBC International Service (as Radio Canada International was called before 1970) first launched in February 1945 with three new 50kW shortwave transmitters, obtained from RCA in the United States.  The callsigns used were constructed with four letters, all beginning with CH or CK. The basic callsign, CKCX, identified both the station, and also the shortwave channel 15190 kHz.

Over in England during the15 year period extending from 1930 to the end of World War II in 1945, the BBC in London used a total of 46 shortwave transmitters installed at eight different locations scattered throughout different areas of the British Isles, including Northern Ireland. This enormous assemblage of shortwave transmitters ranged in power from 7.5 kW right up to 250 kW.

Various callsigns were used; but again not with one callsign per transmitter, but rather with one callsign per shortwave channel.  These callsigns, numbering more than one hundred, ran from GRA to GSZ and GVA to GWZ.

Under these circumstances, the BBC operated with maximum flexibility, and they could use any transmitter, at any location, at any desired power level, on almost any shortwave channel.  It was therefore impossible for international radio monitors in those days to know just which transmitter at which location they were listening to.

Over in Australia, the old AWA shortwave station located at Pennant Hills, an outer suburb of Sydney, New South Wales, was on the air with an interesting mixture of callsigns.  For example, they operated three different communication transmitters during the middle of the 20th century, and these shortwave units were identified with the internationally recognized Australian callsigns VLK, VLM & VLN.
However, when AWA Pennant Hills was calling:-
England with communication traffic, they identified with the callsign VLK,
when they were calling Java, they used VLJ,
and when they were calling New Zealand, they used VLZ, all without regard to the transmitter or even the frequency being used.

When Radio Australia was launched at the end of 1939 under the slogan, “Australia Calling”, transmitters VLK & VLM were dedicated to the new broadcast service with new callsigns, as VLQ & VLQ2.  However, even that was not consistent, because sometimes transmitter VLQ was also on the air with a numeric callsign as VLQ5.

In 1939, the 2 kW ABC shortwave transmitter at Lyndhurst, Victoria was used for both the ABC Home Service as well as Australia Calling under the callsign VLR.  In mid-1941, an additional 10 kW shortwave transmitter was installed at Lyndhurst, which was inaugurated under the same callsign VLR.  But, to avoid confusion with the two transmitters at the same location using the same callsign, eventually the callsign for the new transmitter was changed, and it became identified as the more familiar VLG.

In 1946, another 10 kW shortwave transmitter was installed at Lyndhurst, and this one was identified as VLH.  In those post-war years, program relays of medium wave 3AR & 3LO via VLR and VLH were quite regular and consistent for Home Service coverage throughout Australia.

At one stage back then around mid-morning, both 10 kW transmitters were on the air using the callsign VLH on two different shortwave channels, with overlapping scheduling for a quarter of an hour or more.  Thus, by that stage, VLH had become more of a program service on shortwave rather than a transmitter identification.

The Shepparton shortwave station broadcast Radio Australia with three transmitters identified as VLA, VLB & VLC.  When these transmitters were given a new shortwave channel, a suffix number was added, such as:-
VLA2 on 9615 kHz and VLA3 on 9680 kHz
VLB3 on 11770 and VLB4 on 11810, and
VLC9 on 17840 and VLC10 on 21680

However, this system became quite cumbersome, so Radio Australia changed the system in mid-1951 and the suffix numeral indicated the MHz band; thus:-
VLA7 was used for any channel in the 7 MHz 41 metre band
VLB9 for any channel in the 9 MHz 31 metre band, and
VLC11 for any channel in the 11 MHz 25 metre band.

These days, use of callsigns throughout the world to designate shortwave transmitters is very much decreasing.  The shortwave station Voice of Hope – Africa that I help manage in Lusaka, Zambia has two 100 kW transmitters, but they’ve never been assigned callsigns by the licensing authority there.  And here in the United States, the FCC currently only allocates one callsign per commercial shortwave station, regardless of how many transmitters are in use.  For instance, WRMI in Okeechobee, Florida, WBCQ in Monticello, Maine, and WWCR in Nashville Tennessee all have multiple transmitters, but only one callsign each.

Our editor-in-chief, Dr. Adrian Peterson, perhaps harking back to an earlier era, would still prefer a system of identification for shortwave transmitters as one callsign, one transmitter.  It seems, however, that particular boat has long since sailed.  Back to you, Jeff.
