Old Fashioned Band-Scan after the Solar Storms

by TomL

This is just an old fashioned band scan to randomly see what I could hear after last week’s solar perturbations when the Solar Flux Index went well over 200.  I considered what I could hear on the shortwave broadcast bands, even though the SFI had quieted down to around 135.  Would the ionosphere still be holding on to the charge built up during the solar storms?  The date and time was January 30, 2023 around 1400 through 1600 UTC.  By the way, as of today (February 2), the bands are dead and cannot hear any of these even though the Solar Flux is about the same!

I will not have time to describe my antenna setup now at my noisy Condominium in detail.  I have been experimenting with a DX Engineering NCC2 antenna phasing device for the past year with somewhat good results.  I had to place dedicated receive antennas in many different ways in order to find an arrangement that works in conjunction with the two Ham Radio antenna wires out on the porch.  Sometimes it helps by lowering the noise, sometimes the native antenna by itself, or peaking the signal,  has better reception even though it might be slightly more noisy.  By matching one of two receive-only antennas (the left Heathkit switch) with one of the Ham Radio antennas (the right Daiwa switch), I can usually eke out some extra decibels of signal-to-noise improvement.

Don Moore’s Photo Album: Cuenca, Ecuador (Part One)

Don Moore’s Photo Album: Cuenca, Ecuador (Part One)

by Don Moore

For me travel is all about seeing new places and having new experiences. When I retired in 2017 my plan was to spend the next fifteen years visiting new countries and new places in countries I already knew. Is that a viable goal? Three years ago while crossing the border from Ecuador to Colombia I shared a taxi with Dutch man who, like me, was traveling overland by bus with just a knapsack and a suitcase. And two weeks earlier he had celebrated his eightieth birthday. I don’t remember his name but he’s my hero.

The pandemic put a pause on travel but I’m happy to be back on the road. I’m currently in Ecuador, the country where I’ve spent more time than anywhere except the United States and Honduras. After landing in Quito at the beginning of December I visited four provinces I hadn’t been to before, including spending three nights at the bohemian beach town of Montañita where I had some good DX. I like seeing new places but there is also something to be said for returning to a familiar place that holds a special meaning. For me that place is where I am now – Cuenca, Ecuador.

My ex-wife and I finished our Peace Corps service in 1984, flew home to get married, and then in January 1985 flew to Quito, Ecuador to begin a long journey that would take us overland all the way to Buenos Aires and back. On our way to Peru in late February we stopped for a few days in Cuenca and fell in love with the little city. We visited Cuenca again in July at the end of our travels. When we left I knew we would be back but I never could have imagined the circumstances that would lead to that next visit. In 1997 we returned with our seven-year-old daughter to adopt a six-year-old son. We spent almost three weeks in Cuenca doing all the required paperwork but we had no complaints as we enjoyed being there so much. I clearly remember sitting in a park one day and commenting that Cuenca would be a perfect place to retire in someday. I was only ten years ahead of my time.

La Voz del Río Tarqui

Cuenca was home to several shortwave broadcasters over the decades but La Voz del Río Tarqui was probably the best known to my generation of DXers. The station was founded in 1960 by Manuel Pulla but didn’t begin its shortwave service on 3285 kHz until 1982. My loggings of the station run from July 1982 through 1997 but I believe they were on shortwave for a few more years after that. (Don’t confuse La Voz del Río Tarqui with Radio Tarqui, a sometimes broadcaster from Quito on 4970 kHz.)

La Voz del Río Tarqui in 1985. The facilities inside were no more impressive than the outside of the building was.

La Voz del Río Tarqui takes its name from the famous Battle of the River Tarqui. After the new countries of South America gained their independence from Spain there was often disagreement over just where the boundaries were that they had inherited from Spanish rule. Ecuador was in a union with present-day Colombia and Venezuela until 1830 and during this time Peru claimed much of present-day southern Ecuador, including Cuenca and Guayaquil. In 1828 a large Peruvian army occupied Loja, to the south, and a few months later marched north to complete their conquest. In February 1829 General Antonio de Sucre, a hero of the war of independence, met the Peruvians on the banks of the Tarqui, twenty-five kilometers south of Cuenca. Both sides suffered heavy losses but Sucre’s army routed the Peruvians. Cuenca, Guayaquil, and Loja remained a part of Ecuador. Continue reading

Carlos’ Shortwave Art and recording of the Voice of Korea (January 22, 2023)

Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares his radio log art of a recent recording of the Voice of Korea’s Japanese Language Service.

Carlos’ goal is to vividly illustrate the broadcaster’s message in his own unique artistic style and is not a reflection of his own beliefs or those of the SWLing Post. His objective is for his artwork to add historical context and put a visual with the news, reporting, and broadcast content:


Carlos notes:

Part of news bulletin broadcasted in Japanese from DPRK’s Voice of Korea radio, via shortwave. Reply message from Chinese President Xi Jinping about the condolence message sent by DPRK’s President of State Affairs Kim Jong-un due the passing of former Chinese President Jiang Zemin.

Jeff’s recordings of HAARP’s Asteroid Sweep Signals

Many thanks to SWLing Post contributor, Jeff Cooper (KJ7LTU), who writes:

Hello Thomas!

First thank you for continuing to update your blog and website. It is such a great resource for those of us still tuning in to those distant waves.

I was doing some listening this morning [December 27, 2022] and checked your blog only to find out the HAARP experiment was underway. I quickly tuned to 9600 kHz and managed to pick up the signal twice in Southern Idaho. I made recordings of the capture and posted them on YouTube:

Please note: To be very clear, these are recordings of the transmitted sweep signals from HAARP. These are not recordings of the actual bounced signal from the asteroid. HAARP and NASA would need an extraordinarily high-gain antennas and radio astronomy-grade low noise receivers to detect a signal at this distance.

1752 – 1810 UTC:

-Jeff Cooper (KJ7LTU)

Thank you so much for sharing these recordings with us. I think HAARP is going to get reports from across the globe. Seems these sweep signals were widely received. I’m very curious if HAARP met any success hearing one of the signals bounced back to earth from the target asteroid. Hopefully, we’ll soon learn!
