Throwback Thursday - vintage frequency voltmeter

Most radio hobbyist, have at least one 'boat anchor' lurking somewhere in their radio shack - and here at Teak Publishing, we have our own in the DX Cabin.

The above photo is of a Philco 128A Frequency Selective Voltmeter. And what is it for ? A Frequency Selective Voltmeter incorporates digital signal processing, based on design to provide high accuracy and stability. The unit is designed for level measurement of the selected frequencies, and also provides functionality of AC and DC voltage measurements. We picked this up at a Bob Grove Auction, and since then, has graced our shack.

Do you have a 'boat anchor' in your shack, or a vintage QSL ? Contact me at the above email address in the masthead. Throwback Thursday comes around once a week - share it with our global followers.

Dxers Unlimited, midweek edition July 17

Radio Havana Cuba - Dxers Unlimied - 17 July 2018
Arnie Coro, CO2KK

Hi amigos radioaficionados...listening via short wave and also by means of our streaming audio from am your host Arnie Coro,radio amateur CO2KK now ready to start the middle of the week edition of your favorite radio hobby program.

Item One...As anyone monitoring the HF bands will easily find out,the low solar activity continues to limit the chances of short wave propagation on frequencies above15megaHertz,even during the best times of the day at any given location.The exception comes when sporadic E layer openings move the maximum usable frequency up past the25megaHertz range. Observations confirm that solar cycle 24 continues to show very weak activity as compared with any of the previous 5 solar cycles. As a matter of fact today Tuesday July 17 we have seen so far twenty consecutive days without sunspots…

Item Two:You have questions and I do my best to answer them...Yes amigos,every day the e'mail brings in most interesting questions from listeners all around the world...Like for example the one sent by Manuel from Mexico City, who listens regularly to our 15140 kiloHertz frequency. Manuel is asking why it is not possible for him in Mexico city to pick up shortwave stations from other countries in the Americas besides Cuba, Brazil and  his local Radio Educaci√≥n that he receives via the ground wave signal.

Well amigo Manuel, first of all,let me tell you that at this moment they are fewer stations from the shortwave bands with high enough power to be heard on a regular basis. Venezuela was in the process of installing its first international broadcasting transmitting station,but that project is now  at a standstill.

This is Radio Havana Cuba,the name of the show is Dxers Unlimited,and yes amigos,we do send QSL cards to listeners that report our programs, and this is done absolutely free of charge.

Now part two of the answer to amigo Manuel, who lives just outside Mexico City. Besides Radio Havana Cuba,that can be picked up,using a rather simple short wave receiving antenna,you may be able also to pick up several stations from Brazil, as well as maybe Peru and Bolivia,are also on the air, especially on the 60,49 and 31meters bands,but most of them are using low power and simple low cost antenna systems because they are intended to provide local or regional coverage.

When HF bands propagation conditions are good,you may pick up several of those low power stations from Peru, Bolivia, Ecuador, Colombia and Mexico. Reception of those low power shortwave broadcasts, mainly on the 60 and 49meters band, and also at times on 31 meters. This will usually take place very late in the evening during your local time or just before local sunrise.

For both shortwave listeners and amateur radio operators that live in urban areas the installation of an adequate antenna for obtaining best results within the frequency range from 3.5to 29.7 megaHertz is quite a challenge to say the least.City dwelllers, and especially those who live in apartment building face a great challenge when trying to listen or to operate on the 80 to 10 meters ham bands, because of the severe restrictions imposed nowadays regarding the installation of external antennas on any type of building and the extremely high local noise levels.

The rooftops of high rise apartment buildings are an ideal location for VHF,UHF and microwave operation. If you happen to be living at one of the top floors, but are quite useless for that purpose if your apartment is located close to the ground requiring the installation of a very long length of transmission line needed to reach a rooftop antenna and this,if you are fortunate to obtain permission to install it by the building managers. But, despite all those difficulties,I very often come across a ham radio operator that with a lot of ingenuity that manages to operate, for example,on the 20,17 15 and 10 meters bands,using different types of compact antennas.

Fortunately the 12 and 10 meters  HF bands require a much smaller size of antennas small enough to make them fit across a balcony rail. However, 20,17 and 15 meters are certainly the most popular DX bands when propagation conditions are let's say,normal or slightly above normal, and that is why people living in housing facilities with severe restrictions as regards to the installation of external antennas,try, in the first place to put up an antenna system that can be tuned to 20,17and15meters.

One of the regular Dxers Unlimited's listeners,who is also an avid ham radio operator asked about what could be done to install an antenna for the 20,17 and 15 meters band that could fit into his apartment's balcony that measured from one end to the other roughly 5meters or about sixteen and a half feet. That is just enough to install a dual band 12 and 10 meters fan dipole. His already in use 12 and 10 meters fan dipole dipole has brought some local contacts,and also some DX when the band is open,but as everyone now is fully aware,the 10 meter band openings via the F2 layer are going to become very rare indeed due to the lack of solar activity. Remember what I said at the opening of today's program, 20 consecutive days without sunspots

Besides buying an expensive professional magnetic loop antenna with remote tuning, there is another option for our listeners who want to operate on the 20, 17 and 15 meters band. Build a compact short dipole antenna using two easy to make loading coils and two end loading capacitive hats,that will make possible to operate on the 20,17 and 15meters bands with rather good efficiency, and also on the 30meters band with somewhat reduced performance.You must use a balun or balanced to unbalanced one to one broadband transformer at the feedpoint of the antenna. The antenna I suggested fits perfectly into a slightly less than 15 feet or five meters of horizontal space,and when fed via factory made or a homebrew one to one balun and using a wide range antenna tuner has proven to provide excellent performance. One good advantage of this antenna is that it can be installed in a couple of minutes when you want to operate or listen to the radio,and likewise it can be taken down and placed in storage at a corner of the balcony ! The good efficiency of this antenna design despite its short length, is due to the use of two carefully built high Q loading coils and the nice looking well designed end loading spiders,that act as an effective capacitive load.

The two loading spiders are built using four wires that are carefully soldered to a circle made of 6millimeters or about a quarter of an inch copper tubing.Each leg of the antenna is just two and a quarter meters long and they end up connecting to the end loading spiders. The center insulator supports a one to one balun transformer,and the antenna is fed with a short length of RG213 or RG8X coaxial cable that connects it to the antenna tuner. So far,all our experiments with this antenna have proven that it will work quite well with a simple antenna tuner,making possible to operate on the 20, 17and 15 meters bands, as well as on the12,10 and even 6meters band too using an antenna tuner.The fact that the antenna is located inside a balcony,places some limitations as regards to both the overall coverage and also limits its use to power levels not to exceed 25watts for safety reasons regarding the exposure to radio frequency energy.

If you want to learn more about this compact antenna system,especially designed for apartment dwellers, just drop me an email to inforhc at enet dot cu,again 

And now as always at the end of the show, here is Arnie Coro's Dxers Unlimited's HF propagation update and forecast. Expect sporadic E openingsto become less and less frequent after the end of July and solar activity continues to be low but the night time maximum useable frequency curve continues to exhibit its usual upward swing that starts after sunset,something typical of the northern hemisphere summer season.Solar flux around 70 to72 units.And please don't forget to send your signal reports and comments about this and other RHC programs to or via air mail to Arnie Coro, Radio Havana Cuba, Havana Cuba

DXers Unlimited weekend edition, Sunday July 15, 2018

Radio Havana Cuba
Dxers Unlimited' - weekend edition for Sunday July 15 2018
By Arnie Coro, CO2KK

Hola amigos radioaficionados all around the world, listening now to the weekend edition of Dxers Unlimited, coming to you via our SIXTY meters Tropical Band and Short Wave transmitters operating on the 49, 41, 31, 25 , 22 , 19 and 16 meterss bands and also by the streaming audio via Internet and  via the Hispasat 1D geostationary satellite on the transponder 79 vertical polarization...

I am your host Arnaldo, Arnie, Coro, radio amateur CO2KK and now here is item one of today's show....

Current news in the world of short waves .... that are not good at all ...The very bad conditions of short wave radio  continue due to the very low solar activity ... Day after day the solar disk visible from the Earth is completely blank, without a single magnetically active zone, that is without sunspots. On Saturday, July 14, 17 consecutive days had passed without any sunspots being observed. The records of the solar radiation flow in the band of 10.7 meters of wavelengths, continues below 75 units. the ionosphere is not receiving the necessary energy to offer the possibility of long-distance communications via the daytime F2 layer.

More news ... follows the extraordinary progress in the use of digital communications mode called FT8 ... Although the exchange between stations is very limited to 13 characters per contact, it is possible to communicate when the conditions of radio propagation are extremely bad , because the algorithm for capturing the signals manages to receive when those signals are below the noise. Although it is not as sensitive as the JT65 mode, the exchange is done in much less time.

FT8 is the name of this new communication software that continues in development under the baton of Nobel Prize winner Joseph Taylor K1JT author of a whole family of digital programs for communication

The well-known WINDOM antenna of the first years of amateur radio has a current version, which has received several names, of which the most popular is the CAROLINA WINDOM ... whose installation is facilitated because the feed point is located more near to the station because of its asymmetric construction. Several Cuban radio amateurs are successfully using the variants of the Carolina Windom in a version that makes it possible to operate from 80 to 10 meters using a simple tuner or antenna tuner.

The lack of original factory battery packs for the portable transceivers of the two-meters and seventy-centimeters bands is being solved by Cuban radio amateurs by adapting the rechargeable lithium batteries used in cellular telephones to give power to the popular handie talkies, the stations described in amateur radio licenses as personal mobile sets .... The connection of two or three lithium batteries in series makes it possible to feed those equipment that are so important in emergencies. As an additional advantage is that lithium batteries have much greater capacity to store energy and do not have the harmful memory effect  that is observed in nickel cadmium batteries .... The construction of an automatic charger for lithium batteries  has become popular from an original  Cuban design that has proven to be highly reliable .

ASK ARNIE... is now on the air... this is the most popular section of Dxers Unlimited according to your e'mail messages, letters and even while having a QSO with my amateur radio station CO2KK Today's question came from Argentina, where amigo Raul listens via the Internet streaming audio. He tells me in his e mail about the excellent results achieved with a one and half meter diameter circular magnetic loop antenna made using the special low loss coaxial cables that go by the trade mark HELIAX.... He tunes the antenna with a homebrew butterfly capacitor and asks how he could use more power fed to the antenna by replacing the butterfly capacitor... Amigo Raul , your best possible option is to try to obtain a vacuum variable capacitor rated at no less than fifteen thousand volts, because you can then feed about one hundred watts full carrier power to the magnetic loop without running the risk of arc overs...

I also want to remind you and all other users of magnetic loops for transmitting to keep the antennas at a good distance from your operating position, in order to avoid very intense electromagnetic fields... Using a magnetic loop far from the operating position implies the addition of a remote tuning mechanism that is essential when you want to change frequencies... As a side note, a friend that enjoys using the digital communications modes, tunes his antenna to the popular parking spots for the FT8 mode and he does not need to retune the antenna....

Si amigos magnetic loop antennas deserve much more attention by both short wave listeners and amateur radio operators... when you chances of installing a large size external antennas are next to zero SOUND : SHORT MUSICAL INTERVAL The World Football Cup acted as a good reason to put on the air many amateur radio stations using special callsigns with the number 18 included in the callsigns as well as the acronymn >FIFA for international federation of amateur football...
On 10 meters, despite the poor propagation conditions , several of those stations attracted the attention of those devoted fans of the twenty eight megaHertz or 10 meters band...
Here are some of the stations heard on 10 meters last Monday


The other interesting news about low band VHF propagation was that the across the North Atlantic Path between the eastern coast of North America and the British Isles saw a record breaking sporadic E multiple opening that took the maximum usable frequency up to 88 megaHertz... a very rare event by all standards.. On the 21st of June, an also fantastic opening made possible for several Cuban 6 meters band operators to work a number of Japanese stations using CW and Single Side Band....
Due to the lengthy period with a totally blank Sun we may expect more sporadic E layer openings during the second half of July

And now amigos at the end of the show, be on the lookout for more sporadic E skip openings and somewhat better local nighttime propagation on the HF bands...

ee you all at the middle of the week edition of Dxers Unlimited, Tuesday and Wednesday UTC days , just after the half hour RHC English newscast...

Highlights of Solar and Geomagnetic Activity 09 - 15 July 2018

Solar activity was very low throughout the reporting period. The visible disk produced several plage regions but no visible spots were observed. No proton events were observed at geosynchronous orbit The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels. Moderate levels were reached on 09-11 Jul and 13-17 Jul.

Geomagnetic field activity was mostly quiet with several periods of unsettled observed on 11-12 Jul. A slow-moving transient signature was observed in the solar wind midday on 10 Jul from a CME first observed in STEREO AHEAD COR 2 imagery early on 05 Jul. A decrease in solar wind speeds was observed, after the onset, which lowered winds from near 385 km/s to 309 km/s at its slowest point on 11 Jul. Total magnetic field strength peaked at arrival with 13 nT. Bz was mostly oriented either near neutral or northward which produced a quiet to unsettled geomagnetic response throughout the duration of the transient.

Forecast of Solar and Geomagnetic Activity 16 July - 11 August 2018

Solar activity is expected to remain very low throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to range from moderate to high levels. Moderate to high level are expected over 21-31 Jul and normal to moderate levels are
expected through the remainder of the outlook period. All enhancements in the greater than 2 MeV electron flux are due to the anticipated influence of multiple, recurrent CH HSSs. The Geomagnetic field activity is expected to range from quiet to G1 (Minor) at geomagnetic storm levels. Unsettled levels are expected on 16 Jul, 21 Jul and 24 Jul. Active levels are expected on 20 Jul and 22 Jul; G1 (Minor) geomagnetic storm levels are expected on 23 Jul. All increases in the geomagnetic activity are in anticipation of multiple, recurrent CH HSSs.

KiwiSDR TDoA Finding Now Freely Available for Public Use

An interesting article, of special interest on TDoA (Time difference  of Arrival), a direction finding technique.

A few weeks ago we posted about some experimental work going on with Time Difference of Arrival (TDoA) direction finding techniques on KiwiSDR units. The idea is that public KiwiSDRs distributed around the world can be used to pinpoint the physical locations of any 0 - 30 MHz transmitter using the TDoA technique. This feature has recently been activated and can be accessed for free via any KiwiSDR.

The KiwiSDR is a US$299 HF SDR that can monitor the entire 0 - 30 MHz band at once. It is designed to be web-based and shared, meaning that the KiwiSDR owner, or anyone that they've given access, can tune and listen to it via a web browser over the internet. Many public KiwiSDRs can be found and browsed from the list at or by signal strength and location on this website.

Summer 2018 International Shortwave Broadcast Guide Now Available at Amazon

Older ham radio operators and radio listeners might remember a time when shortwave radio stations broadcast a nearly constant drumbeat of political propaganda during the Cold War years. Shortwave radio stations such as Radio Moscow, the Voice of America, and the BBC, to name a few, played an important ideological role during that confrontation between the East and the West.

Once again, Global Radio broadcasters have moved to the front lines at what is now shaping up as a new Cold War by some of the world’s major super powers.

Voice of Indonesia active, though irregular on shortwave

The World Radio TV Handbook summer schedule update on 11 July 2018, is reporting that Voice of Indonesia is active, through broadcasting irregularly. The station is being relayed via Radio Republik Indonesia, Palangkaraya, using their 10 kW domestic service transmitter.

For 'Country-Counters', Palangkaraya is counted as Kalimantan/Borneo on the NASWA County List. This would be an excellent opportunity to add this to your country totals. Prior to this shift, Voice of Indonesia counted as Java.

Revised complete schedule, broadcasting daily when active

Shortwave Radiogram schedules, July 13-16

Images from March 2018 programming
Hello friends,

Last week’s broadcast Saturday on 9400 kHz from Bulgaria went off the air a few minutes after Shortwave Radiogram began at 1600 UTC. At least on Twitter, @SWRadiogram and followers, we had fund speculating about why the transmitter went off the air (e.g., Kim broke another transmitter) and if it would return to the air before the end of the half hour (it didn’t).

A video of that ill-fated Saturday 1600 UTC broadcast is provided by Ralf in Germany, with the addition of the same broadcast quickly uploaded to Soundcloud to provide an alternative to the missing shortwave. (The images were very clear!) Another video of the Sunday 2330-2400 UTC show on 7780 kHz from WRMI Florida is provided by Scott in Ontario. An audio archive is available from Mark in the UK. And analysis of program 55 was prepared by Roger in Germany. 

Also during the past week, Shortwave Radiogram listeners were receiving and decoding SSTV images from the International Space Station. Complete sets of images were received by Gaudenzio in Italy and Mercouris in Greece. (To generate more interest in Shortwave Radiogram, I need to find a way to transmit the show from orbit.)

This weekend is our usual pattern of MFSK32 and MFSK64, with four interesting news stories and seven images.

Here is the lineup for Shortwave Radiogram, program 56, 13-16 July 2018, in MFSK modes as noted:

 1:34  MFSK32: Program preview
 2:47  Climate change causing extreme weather*
 8:10  MFSK64: Spiders use electric fields to take flight*
13:18  Young stars visible in new infrared image*
16:26  Ham-designed gear used in Thailand cave rescue*
20:05  Images of the week*
26:15  MFSK32: Closing announcements

Radio DARC upcoming special weekend broadcast

With 300kW from Wittenberg via Vienna to North America

Wittenberg. (xv) The WRTC will be covered in two special broadcasts by Radio DARC. The radio show of the German Amateur Radio Club e.V. will broadcast a program in English on Saturday, July 14 from 11.00 to 12.00 UTC using the 49m shortwave band on 6070 kHz. Especially for the many people interested in WRTC from North America, the program will also be broadcast on 13860 kHz at the same time. The six-hour time difference makes it possible for the show to serve as a "breakfast radio" WRTC News on the East Coast of North America. There is expected to be a high level of interest from North America as not only did a total of 14 teams from North America qualify but also the defending champions Daniel Craig (N6MJ) and Chris Hurlbut (KL9A) are from the USA.

BBC's Global audience rises to 376 million

Date: 22.06.2018     Last updated: 27.06.2018 at 14.26
Category: World Service
The BBC is reaching a record weekly audience of 376m people, new figures published today reveal.
The figures - the Global Audience Measure (GAM) - show how many adults the BBC reached weekly with its news and entertainment content in the year 2017/18.
The BBC World Service, which has just undertaken its biggest expansion since the 1940s, has seen its audience increase by 10m, to 279m.
The total global news audience has risen by a million, to 347m.
The GAM shows the way people access their news is continuing to change around the world. With the increased availability of cheap smartphones around the world, audiences are continuing to switch to digital platforms for news. Overall, online news website audiences have grown by four million, with social media audiences up by nine million.
The English language international website,, continues to perform well even in competitive markets like the USA, adding two million weekly users this year.
More people listen directly to World Service English via the internet than by any other method - a total of 27m. And World Service English podcasts now reach one million people every week.

The Highest Powered Mediumwave Station in the Southern Hemisphere

On previous occasions here in Wavescan, we have presented Part 1 and Part 2 in a four part mini-series on the topic of The Highest Powered Mediumwave Station in the Southern Hemisphere, the story of 2CO in Corowa New South Wales.  Today, we present Part 3 in this same series, and that will take us to a country relay station in another Australian state, this time the state of South Australia.

It was on June 23, 1929 that the Australian Broadcasting Company (ABCo) was formed, and they took over a total of eight mediumwave stations in six Australian states that were already on the air.  During their three year tenure of office, the shortlived ABCo established four more mediumwave stations, two of which both qualified for the title of the Highest Powered Mediumwave Station in the Southern Hemisphere.  These two stations were the aforementioned 2CO in Corowa, and then the South Australian 5CK in Crystal Brook, both of which utilized Australian assembled STC transmitters rated with an output power of 7½ kW.

The new 5CK at Crystal Brook was established to give radio coverage to the industrial city of Port Pirie and its surrounding agricultural areas.  Port Pirie was declared South Australia’s first
provincial city (1953), and it is the state’s second largest port, after Port Adelaide itself.

The new ABCo regional relay station 5CK was installed at a country location on Gladstone Road, three miles from the small town of Crystal Brook.  The new mediumwave transmitter, rated at 7½ kW output on 635 kHz, was installed in a newly constructed transmitter building.

Two lattice style steel towers 185 feet tall were erected 265 feet apart, and suspended between these two towers was a center fed Alexanderson style antenna system.  At each end of the antenna system was a drop down lead to earth, with a special tuning coli in a tuning hut for each. 

The antenna system at 5CK was similar in design and style to the somewhat larger antenna system that was erected for station 2CO three months earlier.  Described as a Multiple Tuning System, only three of these systems were ever erected in Australia; the aforementioned 2CO in Corowa New South Wales, this regional mediumwave station 5CK near Crystal Brook in South Australia, and the “new” 6WF when it was transferred from the Westralian Farmers Building in downtown Perth and rebuilt at Wanneroo in Western Australia (1934), two years after 5CK  was inaugurated. 

It will be remembered that the radio station at Wanneroo in Western Australia was also home to the ABC shortwave transmitters VLW and VLX, as well as for Radio Australia programming beamed to South Africa, Asia, and Antarctica.

Programming for the new 5CK came by landline from 5CL in Adelaide, with occasional local
inserts from a small studio in nearby Port Pirie.  The official opening ceremony was conducted at the 5CL studios in Hindmarsh Square in Adelaide on March 15, 1932, and one of the main speakers was the Post Master General Mr. James E. Fenton, who spoke from Canberra by landline.

Reception reports for the new 5CK were received from listeners throughout Australia, far and wide.  Listeners in Sydney and country Lismore in New South Wales, and in country Victoria, proclaimed triumphantly that the new 5CK was the strongest signal from any radio station in Australia.

As time went by, an additional new mediumwave station 5AN joined the studio production team in Hindmarsh Square, and this new station then provided most of the landline programming to 5CK.  To this day, 5CK is still on the air under its original callsign, and it now radiates 10 kW on 639 kHz.

It is true, that back then in the early 1930s, both 2CO in Corowa and 5CK in Crystal Brook were the most powerful mediumwave broadcasting stations in Australia, and also in the Southern
Hemisphere.  However, they did not retain that honor for very long; station 2YA in Wellington in the
sister dominion New Zealand soon took over that honor.  And that’s our story next time, when we present another episode of the interesting historic topic, The Highest Powered Mediumwave Station in the Southern Hemisphere.
