Highlights of Solar and Geomagnetic Activity 11 - 17 December 2017
Solar activity was quiet throughout the entire reporting period. The strongest event was a B6 flare from a plage region on the E. limb at 11/0052 UTC. A filament was observed in SDO/AIA 304 imagery lifting off of the SE quadrant, near S25E47, at approximately 15/1229 UTC.

The event was modeled using WSA/Enlil which suggested the potential for the periphery of the CME to become geo effective around 19 Dec. No additional Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.  The greater than 2 MeV electron flux at geosynchronous orbit was at normal to high levels on 11 and 17 Dec, normal to moderate levels
were observed on 12 and 13 Dec and moderate levels were observed on 14-16 Dec. A maximum flux of 2,300 pfu was observed at 11/0000 UTC.

Geomagnetic field activity ranged from quiet to G1 (Minor), mostly due to CH HSS influence, during the reporting period. Quiet levels were observed on 15-16 Dec; quiet to unsettled levels were observed on 11 and 13-14 Dec; quiet to active levels were observed on 12 Dec; the peak levels of quiet to G1 (Minor) levels were observed 17 Dec.

Forecast of Solar and Geomagnetic Activity 18 December - 13 January 2018
Solar activity is expected to be at very low levels throughout the forecast period.  No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geos nchronous orbit is expected to reach moderate levels on 18 Dec, 22 Dec - 01 Jan, and 07-13 Jan; high levels are likely on 19-21 Dec and 02-06 Jan. All increases in electron flux are anticipated due to the expected
influence of recurrent CH HSSs.

Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 18-19 Dec, 01 Jan, and 13 Jan. Active conditions are likely on 20 Dec, 27 Dec, 02 Jan, and 08 Jan. Unsettled levels are
likely on 21-22 Dec, 28 Dec, 31 Dec, 03 Jan and 09 Jan. All elevations in geomagnetic field activity are anticipated from multiple, recurrent CH HSSs. The remainder of the forecast period is expected to observe quiet conditions.

Shortwave Radiogram programming


Hello friends,
Sorry about the rerun during last weekend’s broadcast Saturday at 1600-1630 UTC broadcast on 9400 kHz. Listeners who did not receive the promised Flamp transmission can decode from audio provided by Roger in Germany and video provided by Scott in Ontario. Another Flamp item will be broadcast this weekend.

Most of this weekend’s Shortwave Radiogram will be in our usual MFSK32, with four images. But we will also include three 8PSK modes: 8PSK-125FL, 8PSK-250FL, and 8PSK-500F. The RSIDs should switch Fldigi to the correct modes. If you must change modes manually, note that the first two are 8PSK-125FL (not -125F) and 8PSK-250FL (not -250F). You can read about the 8PSK modes here. (Sorry, these 8PSK modes are not yet available on TIVAR or AndFlmsg.)

 The 8PSK-500F news item uses Flamp. Download Flamp from here and read the manual here. Under the Flamp Configure menu, select “Auto sync flamp to fldigi mode selector.” This will force Flamp to use whatever mode Fldigi is using. Make sure Flamp is running before the 8PSK-500L transmission begins.

This time we will use smaller blocks with Flamp, to improve the chances that the file is received 100%. There will be 25 blocks of 240 bytes each, transmitted four times. If the file is received 100%, click Flamp’s File > Folders > rx, and the file China_internet_conference.txt should be found in the folder for the date of reception.

 If possible, record your reception. You can try to decode the 8PSK items, including the one in Flamp, several times. Experiment with different audio players (Windows versus VLC, etc) and different equalizer settings, compressors, and other audio tricks.

The Slow Show. This weekend, the broadcast Sunday at 2330-2400 UTC, providing poor reception in most parts of the world as we approach the winter solstice, will entirely be in the Olivia 128-2000 mode. This is a very slow mode, only 17 wpm, but it might be able to overcome difficult conditions. Even if you cannot hear the tones or see a trace on your waterfall, you might still be able to decode the text. Make sure that Fldigi’s squelch (SQL) is off. If your reception is bad, this could be interesting. If it is good, this will be as much fun as watching paint dry.

There is no RSID for Olivia 128-2000, so you need to set it manually. Under the Fldigi Op Mod menu, select Olivia > Custom: then dial up a bandwidth of 2000 Hz, with 128 Tones. Again, record your reception if possible. You can then experiment with the integration period in that same menu. If you increase the number of FEC blocks, your decode might improve. It will also increase the delay time between hearing the tones and seeing the text print out, but this is less of a problem in receiving a broadcast than in an amateur radio QSO. Read about Olivia, including the integration period, here. Also try different audio players and settings. (Sorry again: TIVAR and AndFlmsg do not include Olivia 128-2000.)

German Radio Station in Canada During World War II


During the era of World War II, in the middle of last century, the German armed forces in Europe were at a disadvantage regarding weather patterns coming across the Atlantic into the continent.  The Allied forces had an advantage in that they could readily obtain current weather information from Canada and the United States, as well as from Greenland and Iceland, thus enabling reliable weather forecasting in England.

            In an attempt to obtain reliable weather information from across the Atlantic, the German authorities developed a plan whereby they also could have access to this needed information.  Under the concept of the project Wetter-Funkgerat Land, Weather Radio for Land, WFL, they would plant small radio transmitters at suitable locations in North America and upon suitable islands in the North Atlantic.

            A total of 20 or 30 of these weather reporting portable automatic radio stations were constructed and assembled by the German company Siemens radio manufactory, based upon a design developed by Dr. Ernst Ploetze and Edwin Stoebe.  Each weather radio station contained weather measuring instruments, a telemetry system, and a 150 watt FK type transmitter manufactured by the Lorenz radio company.  All of the equipment for each station was stowed into 10 metal cylinders for easy transportation to desired locations.  

            The clandestine weather radio station destined for installation in Canada was identified as WFL26 which would operated on 3940 kHz and it was estimated that its almost one ton of batteries would provide power for 6 months of operation.  This automatic radio station was configured to broadcast weather information in telemetry codes for 2 minutes, every 3 hours.

            On September 18, 1943, German submarine U537, commanded by Captain Peter Schrewe, left Kiel in Germany on its first combat patrol.  On board was this weather radio station WFL26, the 6th of 21 that were manufactured.  Also on board were two German meteorologists/radiotricians from the Siemens company, Dr. Kurt Sommermeyer and his assistant Walter Hildebrandt.  

            On the voyage across the Atlantic, submarine U537 was damaged when it struck an iceberg during a mid autumn storm.  Because of the damage, the submarine was no longer able to submerge, and it had lost its antiaircraft gun.  Nevertheless, the submarine continued on its dangerous and lonely journey.      

            On October 22 (1943), the submarine arrived at the coast of Northern Labrador, which at the time was part of the separate British territory of Newfoundland, though these days it forms part of the Canadian province of Newfoundland-Labrador.  Two days later, the submarine arrived at Martin Bay right on the northern tip of Labrador, as far away as possible from roving bands of local Inuit hunters. 

            The radio station was assembled and set up on the top of  a 170 ft high hill, some 400 yards inland, and at the same time the damaged submarine was repaired.  Much of this work was performed during the hours of darkness in this northerly location.

            Weather Radio Station WFL26 was identified with the station logo and the name of a non-existent organization, the Canadian Meteor Service.  As a camouflage cover up, a few empty American cigarette packs and matchbooks were thrown around.           

            In just 28 hours, the project was completed, the radio station was actively functioning, the submarine was repaired, and they began their departure from the North American shores of Labrador.  The submarine lay underwater in the Labrador Sea for a while, and they monitored the initial  transmissions from weather radio station WFL26. 

            To begin with, the station was noted on air with a good signal, though the first broadcast was observed to be 3 minutes late.  However, on successive days, the signal began to deteriorate, until the station went completely silent just 3 weeks later.

            Another monitoring report states that there were jamming transmissions on the same shortwave channel, 3940 kHz.  However, it is suggested that this was not deliberate jamming because the station was still unknown to the Allies.  It is probable that the channel was in use at times by other legitimate users who knew nothing about this new clandestine weather station on the north coast of Labrador.             

            On three separate occasions as submarine U537 was departing the western areas of the Atlantic, they successfully repelled and escaped from attacks by single planes from the Royal Canadian Air Force.  The submarine successfully reached the shores of occupied France at Lorient on December 8 (1943), at the end of 70 days at sea.

            The silent weather radio station lay abandoned and exposed near the edge of Martin Bay for many years, and there is no record of any human sightings of this station until the year 1977.  It was then that geologist Peter Johnson with an exploratory team happened to come across the derelict radio station, but, thinking that it was an abandoned Canadian station, they simply left it as it was. 

            Then it was that a retired Siemens engineer in Germany named Franz Selinger began research for the writing of a history of his radio company.  He came across a reference to weather radio station WFL26.  He contacted Canadian Department of Defence historian Mr. W. A. E. Douglas, who then organized a team to visit the area in northern Labrador in 1981. 

            This exploration party travelled to Martin Bay on board a Canadian Coastguard ship, and the Siemens historian Franz Selinger was also with them.  They found the station that was still there 38 years after it was first installed, though some of the canisters had been broken open and the internal components had been strewn around.

            The remaining equipment was salvaged and retrieved, and it is now on display in the Canadian War Museum in Ottawa.

Highlights of Solar and Geomagnetic Activity 04 - 10 December 2017 Solar activity was at very low levels. Regions 2690 (N07, L=332, class/area Bxo/010 on 06 Dec) and 2691 (S03, L=221, class/area
Axx/010 on 10 dec) were both relatively quiet and stable throughout the period. No Earth-directed CMEs were observed. 

No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 04-05 Dec and increased to high levels on 06-10
Dec following CH HSS influence.  Geomagnetic field activity was at quiet to active levels on 04-06
Dec with G1 (Minor) storm conditions observed on 05 Dec due to influence from a positive polarity CH HSS. Quiet to unsettled conditions were observed on 07 Dec as CH HSS effects waned. Quiet
conditions prevailed for the remainder of the period.

Forecast of Solar and Geomagnetic Activity 11 December - 06 January 2018
Solar activity is expected to be at very low levels throughout the period. 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 11 Dec, 13-17 Dec, 19-21 Dec and 02-06 Jan following recurrent CH HSS events. Normal to moderate levels are expected at all other times during the period.

Geomagnetic field activity is expected to be at quiet to active levels on 11-13 Dec, decreasing to quiet to unsettled levels on 14 Dec due to positive polarity CH HSS effects. Quiet conditions are
expected on 15-16 Dec. Unsettled to active conditions are expected on 17-21 Dec, with G1 (Minor) storm levels on 18 Dec due to recurrent positive polarity CH HSS influence. Quiet conditions are
anticipated from 22-26 Dec, followed by unsettled to active levels on 27-28 Dec due to negative polarity CH HSS effects. A return to quiet conditions is expected on 29-30 Dec. Predominately unsettled to active conditions are expected on 31 Dec-03 Jan, with G1 (Minor) levels likely on 01 Jan, due to effects from a recurrent positive polarity CH HSS. Quiet conditions are expected for the remainder of the period.

Abandoned Radio Stations


On a previous occasion here in Wavescan, some three weeks back, we presented the story about abandoned radio stations in the United States, of which there seems to be quite many.  In this our topic for today,  Abandoned Radio Stations in other countries, we take the countries in alphabetic order.  Hence, Australia seems to be at the top of the list.

            In the city of Melbourne, there are two radio facilities that were previously in use by the well known mediumwave station 3AW.  In March 2010, station 3AW moved its studios from a downtown building into a new facility at suburban Docklands. 

            It was originally intended that the downtown building housing the previous studios of 3AW (and other radio broadcasting stations also) would be soon be demolished to make way for a new high rise building.  Instead, the building lay abandoned for several years, and it became a haunt for the homeless, though some of the studio and office areas of the previous 3AW have been spared graffiti and vandalism.

            On an earlier occasion, 3AW moved its transmitter from one location to another, and the tower at the old location remained standing for some years.  It too stood abandoned, until it was demolished more recently.

            The small settlement at Cook, on the Trans Australia railway line running 2500 miles from Sydney to Perth, is located in South Australia rather close to the border with Western Australia.  Over this area, the railway line runs absolutely straight for just on 300 miles.

            There was a time when the railway siding at Cook was quite a large town with a population of some 200 residents, with its own hospital, a school, an airstrip, a swimming pool and a grassless golf course.  These days though the resident population is less than half a dozen.

            Back then during the time of its prosperity, the town of Cook had its own radio broadcasting station under the callsign 5CAS.  The callsign 5CAS would be correct for South Australia, and it looks like a regular three letter callsign for an FM station. 

            However, nothing more is known about this station, and it is not shown in any official lists of radio stations in Australia.  The callsign 5CAS is shown in a photo of a glass door in a building at Cook, obviously leading into what was once their local radio station.  We would suggest that 5CAS was a local, probably unlicensed community FM radio station; the 5 suggests South Australia, and the three letters CAS could stand for Cook Amateur Station.

            Bermuda is a group of low forming volcanoes some 700 miles off the continental coast of North America.  They are a British possession with a total of 181 islands, 8 of which are inhabited.  

            In 1955, the US navy opened a radio receiving station at the beachside on Tudor Hill, Bermuda.   This top secret station was established for the purpose of listening to Russian submarines on their way to the Americas and Cuba during the Cold War. 

            This American facility was abandoned in 1995, the roof has collapsed, and trees and shrubs are now growing inside.  However, the building itself seems to be quite sturdy, and it seems that it could easily be converted into a beachside tourist resort.

            At Clear Creek near Toronto in Canada is an old abandoned radio station that supported air flights inbound and out during World War 2.  A lot of the vandalized electrical and electronic equipment is still in place.

            Also a NATO communication station lies abandoned near Ottawa, the capital city of Canada.  This very solid building, constructed in steel and concrete, is totally intact, though vandalized.  Electrical connections are still evident, as is also a small corner reflector antenna on top of the building that was used for microwave reception.  This station, in the middle of a wide green cultivated field, was abandoned in 1985.

            Inside a major tourist shopping plaza in Dubai, a very modern radio station, together with its offices and studios, sits open to the public view, but it is simply not in use, just abandoned.  It seems that this planned radio station fell victim to a downturn in the local economy. 

            Over in England, there are two major historic shortwave stations parts of which simply lie abandoned.  These long term magnificent stations were located at Borough Hill near Daventry, and at Rugby in the central midlands.

            The first test broadcasts from the two new 10 kW STC transmitters at the BBC Daventry shortwave station began on October 25, 1932 under the callsign G5SW, even though the actual G5SW transmitter was not located at Daventry; it was still on the air from the Marconi facility at Chelmsford, some 80 miles distant.

            The final broadcast from the BBC Daventry was heard on 15070 kHz via Sender 204 and it      closed at 1130 UTC on Sunday March 29, 1992.  Thus ended 60 years of illustrious international shortwave broadcasting from one of the world’s most famous shortwave stations. 

            Some of the BBC buildings at Borough Hill were taken over for other radio related and non radio related activities and events, and all of the radio towers were ultimately demolished.   Much of the area where the antenna towers stood is now a pleasant park where locals like to run their dogs, yet there are still some reminders of this once mighty shortwave station.  Half a dozen of the concrete blocks that supported the antenna towers for the 5XX longwave and mediumwave transmitter are still in place, abandoned as they were when the towers themselves were felled. 

            Not faring so well was the huge radio station operated by the GPO, General Post Office, near Rugby in Warwickshire in England.  This station was opened on January 1, 1926 with just one transmitter, though verily a massive unit at 350 kW, and it operated on longwave as the key station in the Imperial Wireless Chain under the callsign GBR.  At one stage, with all of its 57 shortwave and longwave transmitters, Rugby Radio was acknowledged as the world’s largest radio communication station.

            Rugby Radio was finally closed in April 2000 after nearly ¾ century of illustrious service.  The facility was simply abandoned and junked.  However we should add, to their credit, that the entire estate is currently under development as a large housing addition. 

            Another huge communication station was located at Kahuku on the northern tip of the island of Oahu in Hawaii.  RCA Kahuku began its life as a Marconi wireless station with just one transmitter, a 230 kW rotary spark unit under the callsign KIE.  The Marconi wireless station at Kahuku was officially opened on September 24, 1914 way before Hawaii became a U.S. state in 1951.  There were just on 200 official visitors in attendacne, most of whom travelled by narrow gauge sugarcane train and then walked the final distance. 

            Sixty four years later in 1978, this same Kahuku communication station was closed due to the availability of international communication by satellite, and all of its unnumbered shortwave transmitters were silenced.  These days, RCA Kahuku is just totally abandoned, even though some of its strongly built and partly roofless buildings are listed as historic Heritage Sites.

            Back in the days of its prosperity, the RCA shortwave station at Kahuku was noted throughout the world for the relay of the very special program Hawaii Calls.  This program was produced live, usually in the courtyard of the Moana Hotel at Waikiki Beach, Honolulu.

             The first broadcast of Hawaii Calls transpired on July 3, 1935, and the weekly series ended forty years later in 1975.  For many years, RCA Kahuku relayed the program on shortwave for rebroadcast on the mediumwave networks in the continental United States.  At the height of its popularity, Hawaii Calls was heard via 750 radio stations throughout the world

The Current Radio Scene in Zimbabwe

QSL via Gayle Van Horn Collection
           As you’ve probably heard, Zimbabwe’s long-time ruler Robert Mugabe resigned this past week as president of Zimbabwe.  This was after the country’s military forces put Mugabe under house arrest several days earlier.  One of the first acts of the military, as often happens during a coup, was to take over the state broadcaster, in this case ZBC, the Zimbabwe Broadcasting Corporation.  It consists of four radio networks and a TV station.  The main radio station is Radio Zimbabwe, also known as Radio Zim.

It has been many years since ZBC broadcast on shortwave.  However, there is a shortwave broadcast going INTO Zimbabwe from a major international broadcaster.  That’s the Voice of America, with its special Zimbabwe Service.



The VOA’s program Studio 7 has been broadcasting to Zimbabwe since 2003, and it has become an important alternative source of news for many Zimbabweans.  The program covers politics, civil society, the economy, health, sports, music, the arts and other aspects of life in Zimbabwe.  The program is multilingual; in English, Shona and Ndebele.


            The VOA Zimbabwe Service appears to be on the air at 1700-2000 UTC daily, with possibly some variations on the weekend.  On the air, they are announcing the frequencies of 909 kHz mediumwave plus 4930, 6080, 13860, 15460 and 15580 kHz shortwave.  These frequencies may be on at different times.  

            We looked at frequency registrations, and 4930 kHz is registered to broadcast to the Zimbabwe area at 0300-0600 and 1400-2100 UTC daily.  That frequency comes from the VOA Botswana relay. The two shortwave channels 13860 and 15460 kHz are registered to be on from 1700-1900 UTC from the VOA site on Sao Tome island.  6080 is registered for 1700-1800 UTC from Sao Tome.  15580 kHz is registered from the VOA Kuwait site from 0300-0500, and from Botswana from 0500-0700 and 1400-2100 UTC.  Some of those transmissions are probably carrying other VOA programs besides VOA Zimbabwe.



The VOA Zimbabwe website, which is www.voazimbabwe.com, says listeners in the area of Harare, the capital of Zimbabwe, may experience jamming on 909 kHz AM.  That may have changed now.  The programming can also be heard on satellite and Internet.  We have noted that the times and frequencies on their website do not correspond exactly to the latest HFCC listings and to what they are announcing on air, so there may be some changes due to the recent dramatic events in the country.
