Dxers Unlimited for broadcast Tuesday July 17 2018

By Arnie Coro
radio amateur CO2KK

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

Here is 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 above 15megaHertz, 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 the 25megaHertz 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 short wave  stations from other countries in the Americas besides Cuba, Brazil and  his local Radio Educación that he receives via the ground wave signal.

Well amigo Manuel, first of all, let me tell you that at this moment there are few stations on the air on the short wave 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. And to answer the other part of your question, I will be back in a few seconds after a short break for station ID. I am your host Arnie Coro in sunny Havana, Cuba…

This is Radio Havana Cuba, the name of the show is Dxers Unlimited, and yes amigos, we do QSL, 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 31 meters 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 short wave 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 your local time or just before local sunrise.

For both short wave 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 3.5 to 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 to10 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 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 … But 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, 17 and 15 meters.

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 is roughly 5 meters 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 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.

Go ahead and 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 15 meters bands with rather good efficiency, and also on the 30 meters 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 6 millimeters 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 the20, 17 and 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 25 watts 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 e’mail to inforhc at enet dot cu, again inforhc at enet dot cu.

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. 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 inforhc at enet dot cu… or via air mail to Arnie Coro , Radio Havana Cuba, Havana Cuba

Dxers Unlimited’s weekend edition for Sunday July 15 2018

Dxers Unlimited’s weekend edition for Sunday July 15 2018

By Arnie Coro
radio amateur 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 meter 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, and it is recorded with a numeric reception report …. 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.

And now more about amateur radio

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 email 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 your chances of installing large size external antennas are next to zero.

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  AO18FWC, 7X2FIFA, CN18FWC, ER18FIFA, 7X2VFK, PZ5RA, K2K, KH1/KH7Z, K2J, II9FIFA, E70FIFA, HZ18FWC, GI6XX, ZB2JK/P, IS0DCR, 2W1ACM, SV6DBG/B, OE18FIFA, IS0HQJ, EA3FYO.

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… See 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… Send your signal reports and comments to inforhc at enet dot cu or via air mail to Arnie Coro, Radio Havana Cuba, Havana, Cuba
