The new Tecsun AN-48x Active Loop Antenna

Many thanks to SWLing Post contributor, Troy Riedel, who shares a link to the new Tecsun AN-48x Active Loop Antenna at Anon-Co. Here’s the description from Anon-Co:

TECSUN AN-48x is an active loop antenna for enhancing shortwave (SW), medium wave (MW/AM) and longwave (LW) reception.

Unlike previous models (DE31MS, A38-LMS) available on anon-co.com, the AN-48x is supplied with adapters to connect the antenna to BNC and RCA sockets. This greatly simplifies hooking up the antenna to TECSUN receivers like S-2000 and S-8800, while it is just as easy to use with H-501, PL-990, PL-880 and the rest of the “PL”-family.

AN-48x also works with portable radios that do not have an external antenna jack!

Effective Frequency Range

Longwave: 120 ~ 400 kHz

Medium Wave (AM): 520 ~ 1700 kHz

Shortwave: 3500 ~ 20,000 kHz

One sunspot into Solar Cycle 25

Nov. 1, 2019: Breaking a string of 28 spotless days, a new sunspot (AR2750) is emerging in the sun’s southern hemisphere–and it’s a member of the next solar cycle. A picture of the sunspot is inset in this magnetic map of the sun’s surface from NASA’s Solar Dynamics Observatory:

How do we know AR2750 belongs to the next solar cycle? Its magnetic polarity tells us so. Southern sunspots from old Solar Cycle 24 have a -/+ polarity. This sunspot is the opposite: +/-. According to Hale’s Law, sunspots switch polarities from one solar cycle to the next. AR2750 is therefore a member of Solar Cycle 25.[…]

Crew 15.61 announces its first DXcamp in the Amazon rainforest

Crew 15.61 announces its first DXcamp in the Amazon rainforest of Brazil and launches its exclusive event site.


From today you can visit https://dxcamp-marajo2019.blogspot.com/ and find all the information about the first DXcamps of the 15.61 Crew.

The DXcamp, will be held between November 15-18 on Marajó island. It’s the first time that an event with these dimensions and characteristics is held in Brazil and maybe in South America.

This DXcamp got the attention of several sponsors who helped the 15.61 Crew, including: C.Crane, SDRplay, DS Antennas (Brazil), Heil Sound, COMPACtenna, Cross Country Wireless, Antennas4Less, NI4L Antennas, Radiwow, RTL-SDR, ELAD, SSB, RadioShack, Antennas Loop DZ by Denis Zoqbi (Brazil), Arrow Antennas and the SWLing Post blog.

“When the Last Tree Is Cut Down, the Last Fish Eaten, and the Last Stream Poisoned, You Will Realize That You Cannot Eat Money ” (Native American saying).

Vital to the planet weather, the Amazon region has suffered fires for several weeks and several organizations have denounced the silence of Brazilian President Jair Bolsonaro about what they consider a devastating environmental crime against Earth. Such disaster has caused worldwide shock and must be remembered, because as something that happened during September, unfortunately the media coverage is focusing probably another disaster.

Marajó is the largest island in Brazil and the largest river island in the world, where the Amazon and Tocantins rivers and the Atlantic Ocean meet. It’s located about three hours by boat from Belém, capital of Pará state.

The 15.61 Crew founders are Martín Butera, correspondent journalist in South America for the British DX Club and Ivan Dias da Silva Júnior, founder of the Regional DX group of Sorocaba/São Paulo.

The objective of 15.61 Crew is not just DX. We will take a direct and committed action to help the planet and raise awareness about the climate change that we are sadly living.

We will plant a tree on behalf of the European DX Council (EDXC). Planting a tree amid the flames that are killing the Amazon rainforest today will certainly not be your salvation, but it will leave a legacy and our contribution for a better world.

We will raise awareness that together we can change this situation with actions such like waste sorting, buying products that can be reused, lowering electricity consumption, eating more organic fruits and vegetables, moving on public transport and so on.

Martin Butera lives in Brasilia, the capital of Brazil, about 27 hours from Belém or 1982 km. Ivan, lives in Sorocaba,São Paulo state, 38 hours from Belém or 2893 km. Both will meet in Belém and then go by boat to the island.

A trip like this requires a lot of preparation. It’s not something cheap or easy to be done. It takes a lot of time, effort and personal expenses to go to these remote places in South America and then share our catches with you. Those who would like to collaborate with us can do by Paypal account, from our website.

Why do we ask your financial support? Airline weight limits and luggage size are a problem in South America and are increasing the costs for us. We also have a long boat trip of more than 3 hours and will rent a house in the island.

Everything is already paid, but your help can made everything easier on the next DXcamps of 15.61 Crew. All donations will be reported on our site, but whoever makes an anonymous donation will be kept anonymous, and we will report only the value. Please consider support our DXcamp camp in Marajó island!

Your contribution will help us take the best listening station we can gather and have more and better chances of getting good results.

The 15.61 Crew founders, have extensive experience in the hobby, both Martin, 29 years as a ham radio operator (LU9EFO-PT2ZDX), with many DXpeditions in several South American islands, as Ivan, started DXing 26 years ago, including contributions to several clubs and as utility stations professional monitor.

Everything we do during this DXcamp will be shared by texts, photos and videos of our correspondent Martín Butera and will be published as son as possible on the BDXC bulletin and SWLing Post blog.

This will be the first of many DXcamps in exotic places that we plan to carry out, always with a message and a proposal for direct action. We are living in a world in danger and our roles as a society can’t be limited only to be only radio listeners.

Thank you!

SDRplay announces the launch of the RSPdx

(Source: SDRplay)

SDRplay Limited has announced the launch of a new Software Defined Radio product – the RSPdx.

The RSPdx is a replacement for the highly successful RSP2 and RSP2pro SDR receivers, which have been extensively redesigned to provide enhanced performance with additional and improved pre-selection filters, improved intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation steps . The RSPdx , when used in conjunction with SDRplay’s own SDRuno software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands.

The SDRplay RSPdx is a single-tuner wideband full featured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz giving up to 10MHz of spectrum visibility. It contains three antenna ports, two of which use SMA connectors and operate across the full 1 kHz to 2 GHz range and the third uses a BNC connector which operates up to 200MHz.

The RSPdx also features a 24 MHz ‘plug and play’ reference clock input which allows the unit to be synchronised to an external reference clock such as a GPS disciplined oscillator (GPSDO)
Due to its exceptional combination of performance and price, the RSP family of receivers have become very popular, and the RSPdx builds on the learning and feedback from many thousands of users across the amateur, scientific, educational and industrial SDR community.
As was the case for the other RSP family members, SDRplay will work with developers of the popular third party SDR receiver software packages to maximise compatibility. SDRplay will also provide multiplatform driver and API support which includes Windows, Linux, Mac, Android and Raspberry Pi 3 and 4.

The RSPdx will be available to purchase in the next few weeks and is expected to retail at approximately £159 GBP or $199 USD (excluding taxes).

For more information visit the SDRplay website on www.sdrplay.com About SDRplay:
SDRplay limited is a UK company and consists of a small group of engineers with strong connections to the UK Wireless semiconductor industry. SDRplay announced its first product, the RSP1 in August 2014

FCC to consider allowing AM broadcasters to transition to digital

All-Digital on the AM Band? The FCC Might Allow It Soon

AM radio station operators in the United States may soon have the option of switching their transmissions to all-digital.

It’s not a done deal; but the concept is about to take a step closer to reality, because the Federal Communications Commission will consider a proposal at its next meeting that would start a process. It will take comments on whether to allow AM band licensees to make the switch if they want.

Ben Downs, VP/GM of Bryan Broadcasting in Texas, petitioned the FCC in March to initiate a proceeding to authorize the all-digital mode of HD Radio.

Allowing stations to use all-digital transmission is an idea that some broadcasters feel could give business-challenged AM stations in the United States new life or at least another option. Turning off their analog signals would mean that most existing receivers could no longer pick up that signal; but many AM broadcasters are currently heard on FM translator simulcasts now. And adding the all-digital AM option could open up new possibilities for them as the number of digital receivers in the marketplace continues to grow.

[…]Chairman Ajit Pai described the proposal in a blog post Monday: “Just as the FCC is trying to keep pace with changes in the market, so are AM radio operators, and the commission wants to give them as much flexibility as possible to compete in the digital age,” Pai wrote.[…]

The Radio World article mentions WWFD in Frederick, MD–a station that has been broadcasting AM digital for over a year. We posted a note about this last year and I even included a short recording/video with reception when traveling through the area.
