Many thanks to SWLing Post contributor, Martin Butera, who shares the following announcement for a new radio enthusiast group in Brazil:
The new 15 point 61 Crew
São Paulo is the largest city in Brazil, the Americas, and the seventh largest in the world, with a population of 11,300,000.
This was the stage for the meeting between Ivan Dias da Silva Junior (a recognized Brazilian radio listener with more than 27 years of experience and founder of the Regional DX) and his colleague, Martin Butera (a renowned amateur radio operator (LU9EFO – PT2ZDX), with 29 years of experience and currently a correspondent journalist for the British Dx Club, covering information from South America for the radio newsletter “Communication”).
The place of the meeting was not an accidental: we met in a noted coffee bar in the Republic Square–an iconic meeting point in São Paulo. Republic Square is located in the city center and is one of the most visited places in Brazil.
We founded the 15 point 61 Crew in São Paulo, on September 3, 2019.
The 15 point 61 Crew is not a DX club, nor a formal registered organization. We are just an informal group who like DXing.
What is the meaning behind our name? The number 15 is the dialing code of Sorocaba and 61 is the Brasília code, joining the two cities where the Crew founders are based–a distance of more than 900 km (Brazil is a huge country!).
The 15.61 Crew doesn’t have political or religious objectives. Our main objective is DXing, with an emphasis on organizing related activities: mainly DXcamps to be held in distant and exotic places, and bringing a new panorama of what is shared about DXing in our country.
We don’t have any kind of administration positions. The 15.61 Crew members are and always will be in equals.
To be a member of 15.61 Crew you just need to be active in our hobby, share information, write items, go with us to DXcamps, develop technical projects, etc.
As we aren’t a DXing club or organization, we will not have a website nor social media. We will share micro-books, especially about our activities through existing media, like the SWLing Post by our friend, Thomas Witherspoon, and by ourselves, because at the moment we are members of other radio related bulletin boards.
Our communication will be through an email address and a Paypal account for those who want to help us to continue developing our activities and also provide feedback on other projects (such as sharing content with other websites, thus creating a virtual collaboration for all).
For this purpose, we are currently developing several projects, such as a 15.61 Crew certificate program and different materials, such as caps, shirts, mugs, etc.
The 15.61 Crew members believe that there are so much things to be heard in the ether and we are prepared for it.
Ivan Dias da Silva Junior & Martin Butera
(15.61 Crew founders)
São Paulo, September 3, 2019
Thank you for sharing this Martin! I hope the 15.61 Crew enjoys some great success and champions a dynamic DX community! If you’re interested in joining this South American crew, contact Martin Butera.
The highly anticipated AirSpy HF+ Discovery SDR has been in the hands of early adopters for about two weeks–and I’ve seen nothing but positive comments!
After a long run (2007-2013) with a Microtelecom Perseus, my SDR of choice became the Elad FDM-S2, and more recently an Elad FDM-DUOr “hybrid” SDR receiver. The two Elads have the same core processing components and identical performance when the DUOr is connected via SDR software.
This week I’ve compared the HF+ Discovery ($169) against the FDM-DUOr ($899) using Studio 1 software and identical modes & settings. The following video features the radios’ performance on a crowded daytime medium wave band from suburban Seattle-Tacoma USA.
Mode, filter bandwidth, AGC, etc. are the same for each radio
768 kHz sampling bandwidth used for both receivers
Stations tuned are:
1320 KXRO Aberdeen WA, 74 miles @ 5 kW (in-line with antenna)
1110 Oak Harbor WA, 78 miles @ 500 watts (in antenna’s null)
1040 CKST Vancouver BC, 147 miles @ 50 kW (in antenna’s null)
1430 KBRC Mt. Vernon WA, 85 miles @ 5 kW (in antenna’s null)
750 KXTG Portland OR, 118 miles @ 50 kW (in antenna’s null)
I purposely sought out signals difficult to hear in the presence of powerhouse stations. Only 1320 kXRO (in-line with my antenna) and 750 KXTG are what you might consider average or fair quality signals. Headphones are recommended for most of these, particularly 1040 kHz.
You’ll note that the pass band has been “pulled” over the edge of the carrier frequency by a few hundred Hertz. This is an excellent trick that can often reduce noise and/or improve intelligibility. It’s a feature unique to Perseus, Studio 1, and SDRuno software; it works in sideband modes and in selectable sideband Sync AM (SAM) mode.
After listening to the signal comparisons, what are your thoughts on the HF+ Discovery? Please leave your comments below.

We report this news on the SWLing Post because the sun and space weather play an important role in radio signal propagation and one’s ability to snag elusive DX.
After publishing news items like this, though, I always receive a number of emails and comments stating that these trends surely marks the end of all radio fun. After all, if there are no sun spots whatsoever, why bother!?!
Truth is, it’s sort of like saying, “the weather looks lousy, I don’t think I’ll be able to have fun.”
I lived in the UK for several years. If I let the potential for lousy weather stop me from having fun, I’d have never gotten anything done!
The same goes for space weather in our radio world.
A couple weeks ago, I made a Parks On The Air (POTA) activation running 15 watts with the Elecraft KX3 into a simple 20 meter vertical in SSB mode. Even though propagation was poor, I logged a new contact, on average, once per minute over the course of 30 minutes! It was non-stop!

As I said in a post last year, use the sunspot low as an excuse to explore frequencies and modes you’ve never used before. Use this as an opportunity to improve your listening skills and the most important part of your listening post or ham station–your antenna system!
I often receive email from people who’ve found the SWLing Post and take the time to write a message to me complaining about the death of shortwave radio: the lack of broadcasters, the prevalence of radio interference and the crummy propagation. They wonder, “is it all worth it?”
“Hey…sounds like radio’s not your thing!”
While this same person is moaning and complaining, I’ll be on the radio logging South American, Asian and African broadcast stations.
I’ll be working DX with QRP power, even though everyone tells me that’s not possible right now.
I’ll be improving my skill set and trying new aspects of our vast radio world.
You see: I’ve learned that the complainers aren’t actually on the air. They gave up many moons ago because someone told them it wasn’t worth it, or they simply lost interest. That’s okay…seriously…but why waste time complaining? Go find something else that lights your fire!
While these folks are complaining, I’ll be on the air doing all of the things they tell me I can’t do.
In the words of Admiral David Farragut: “Damn the torpedoes, full speed ahead!”
Jose Jacob from Hyderabad, India has collected QSL from 132 different stations of All India Radio over a period of 42 years. Radio stations ranging from Shot wave, Medium wave, FM to the latest DRM mode. In the process he has achieved the feat of creating an Indian Record of collecting maximum number of QSL of different stations of a radio broadcaster in India.
As a teenager Jose started listening to radio and started to write to stations way back in 1973, when in his school days. Few years later in 1976 he first wrote to All India Radio, when his reception report was first verified with a QSL. Over next 42 years, he has used various mediums, ranging from inland letters, post cards to emails, for sending reception reporting. Currently he has over 2500 QSL from 130 different countries, many of which left the airwaves.
Over the years, with his special interest in All India Radio, he is one of key country contributors, from India, of World Radio TV Handbook updating about All India Radio to the directory of global broadcasting.
Jose Jacob, is also a licensed amateur radio operator with call sign VU2JOS currently serving as Asst. Director at the National Institute of Amateur Radio (NIAR) www.niar.org

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following guest post:
In these days of declining activity on the shortwave bands, we don’t often enjoy the experience of hearing what we might still call “rare” stations. The new year brought an exception.
On January 1st, 2019 I was tuning around the 48 meter band, which is largely populated by European pirate stations, utilities, and weather stations, when I heard a station on 6,210.20 khz. It was very distinct in that it sounded like an African station — music, with a male DJ/MC and religious songs.
What immediately came to mind was the religious station calling itself Radio Kahuzi, which is in Bukavu, Democratic Republic of Congo.
On January 1st, RK was heard from about 1730 to 1747 UTC when it shut down, playing what Richard McDonald, one of the station’s founders, says were musical pieces that are specific to RK.
On January 2nd, 2019 the station was heard again via Europe-based SDRs, signing off at approximately 1811 UTC.
Here is McDonald’s response to my report (which included an mp3) from January 1st, in which he notes that he even went so far as to give the main station announcer, Gregoire, my name and asked him to mention me in the station’s broadcast:
“I just shared with Gregoire that you had sent a recording of the last minutes of his closing musical sign-off if Radio Kahuzi and he agreed to greet you by name this evening and several days in several languages including English.
You got him saying his name at 5:54 into your recording yesterday,and the ID sign off Mountain Blue-Grass Music was unique to Best Radio Kahuzi in Bukavu!
Barbara Smith will be happy to send the QSL Card and info about us and our National Director and his family situation in case you have any suggestions
Powering off here! Our power cuts off with SNEL often — I just lost a longer reply to you !
But Keep Looking UP ! And Keep On Keeping ON !
Richard & Kathy McDonald”
By the way, according to Wikipedia, SNEL stands for Société nationale d’électricité “the national electricity company of the Democratic Republic of the Congo. Its head office building is located in the district of La Gombe in the capital city, Kinshasa. SNEL operates the Inga Dam facility on the Congo River, and also operates thermal power plants.”
A very interesting page containing the history of Radio Kahuzi, with information about the McDonalds, is at: http://www.besi.org/
As of the time of this writing, it’s unclear to me whether the extended broadcast times of Radio Kahuzi will be continued or if this was a one shot deal linked to the new year — we may have some clarification on this in coming days.
Here’s a video of my January 1st, 2019 reception of Radio Kahuzi:
For now, I am quite pleased to join the group of about 63 DX’ers around the world (that number comes from a link on the RK website called “Shortwave Listeners” that lists SWLs who have heard and contacted the station).
Though it is highly unlikely that Radio Kahuzi will be heard anytime soon in the United States (the station’s schedules shows it being active from 8 AM to 8 PM Bukavu time) at least using U.S.-based radios, whether SDR or traditional receivers, it’s nice to know that there is still a station out there (with 800 watts!) that is a real DX target!
Wow! What a fantastic catch, Dan! Thank you for sharing your catch and, especially, shedding light on this rare DX.
Post Readers: Please comment if you’ve logged and/or confirmed Radio Kahuzi.
Many thanks to SWLing Post contributor Dan Robinson who shares this fascinating story about what has to be “one of the most important occurrences involving a SWBC station that no longer exists — the Voice of Biafra”:
Biafra: One of the rarest of SWBC QSLs
by Dan Robinson
Many SWLing Post readers will no doubt have heard, in recent years, the station Radio Biafra broadcasting via various relay locations on shortwave, and also on the Internet.
Those of us who have been SWLs for many decades remember the history of Biafra and the story of the original Voice of Biafra, which when the station was active on shortwave, before it was closed down by Nigerian government forces.
My own SWLing career began in the late 1960’s, but alas my receivers at the time, and my knowledge of what was on the air were such that I did not hear the transmissions from Biafra (I’m one of those who regrets having missed many former tropical band broadcasters, such as Tonga, Fiji, Gilbert & Ellice Islands (later known as Kiribati) when they used shortwave, and Biafra was on that list as well).
I first learned about the original Radio Biafra from articles written by the late Don Jensen.
In one of those [download PDF], Don re-printed a copy of one of the most famous SWBC QSLs of all time — a Biafra verification sent to DX’er Alan Roth.
Typed on a piece of notebook paper, it had “Broadcasting Corporation of Biafra, P.O. Box 350, Enugu” at the top. Three paragraphs of text followed, referring to Roth’s reception dated January 28th, 1969 of the station on 7,304 kHz.
Pictured with the letter to Roth was the envelope with “Republic of Biafra” mailed from the Biafra mission on Madison Avenue, in New York City. I will always remember the caption, which said that Roth had taken his reception report to the Biafran delegation office which:
“managed to get it flown into the breakaway nation with other official correspondence, on the emergency airlift. Radio Biafra’s chief engineer wrote the verification letter and returned it via the same route. . . a high contrast photo was required to bring out the typing since a well-born typewriter ribbon had been used.”
For decades this Biafra verification to Roth was indeed considered to be the only one in existence, though because so many SWLs and DX’ers were active through the years, it’s always difficult to state this with certainty.
Those of us who collect historic SWBC QSLs, going through thousands of eBay listings, always keep an eye out for cards and letters and station materials.
So it was that a few weeks ago, as I was doing my usual due diligence looking through eBay listings, I noticed something unusual. Listed among SWBC QSLs from a seller in Ithaca, New York was something astounding — another Biafra verification letter!
Looking closely, it seemed to be exactly like the famous QSL letter sent to Alan Roth in 1969, with the exact same date, but sent to a James G. Moffitt, in Dallas, Texas.
Days ticked by — I had the QSL on ‘watch’ status on my eBay account, and as I do for any QSL of high value, I also had it on automatic bid status. For this piece of SWBC history, my maximum bid was very high, something I rarely do unless the item has extreme historic or collectors significance.
I envisioned furious bidding for this Biafra verification, but in the end only four bids were recorded. I won the QSL at what I consider to be a very low price ($81) considering its rarity.
The “Undiscovered QSL of Radio Biafra”, as Jerry calls it in his new article, now resides with me here in Maryland. Unless/until another of its kind emerges somewhere on the QSL market, it has to be considered the only one of its kind in the world.
As for the question of whether this previously “undiscovered” QSL is genuine, Jerry notes the similarities between the Roth QSL letter from 1969, and the one sent to James G. Moffitt, who he notes was active as a DX’er in the days when Radio Biafra existed.
“. . .what about the common date, and date-time-frequency details, in the two veries? If the reports had arrived in Biafra at roughly the same time, it would not be unusual for the replies to be prepared on the same day. As to the common date-time-frequency details, perhaps whoever typed the letters thought these references were standard boilerplate rather than information that was to be tailored to the specific listener. Certainly the frequency could be expected to be the same. The common date of reception is harder to explain, but it is not difficult to see how the almost inevitable difference in dates of reception could have been overlooked. QSLers know that verifications can be wrong in their details, misdated, even sent to the wrong listener. As for the different fonts, and for Alan’s letter being light in appearance and Moffitt’s dark, perhaps the typist changed typewriters because one was running out of ink. We will likely never know for sure, but I think the Moffitt verie (which sold on eBay for $81) is genuine. In any event, the story reminds us how, in every endeavor, even shortwave listening, today’s connected world can cast new light on old events and turn longstanding certainties into question marks.”
I am quite happy with having acquired what surely is one of the rarest of SWBC QSLs. It has been added to a collection that, in addition to my own QSLs that I carefully kept over the years, includes other unique cards, including one from ZOE Tristan da Cunha and the station at the former Portuguese Macao.
Amazing story, Dan! It pleases me to no end to know that someone who values our shortwave radio history–and does a proper job archiving it–has acquired this amazing piece. I especially appreciate the time that you and Jerry Berg put into sharing the history of the Voice of Biafra with the shortwave listening and DXing communities. Thank you!
Readers: As Dan suggests, I strongly encourage you to check out Jerry’s website, On The Shortwaves. It’s a deep treasure trove of radio history.
