New Product: Tecsun AN-48x (now available)

Anon-Co just announced that Tecsun has released their new portable, active loop antenna – the AN-48x (27.99 plus shipping) – and it is available for purchase.  Copied below is their announcement:

Tecsun has launched its latest antenna which is now available at Anon-Co! This active loop antenna has a portable design and aims to enhance AM (LW, MW, SW) frequencies. The antenna comes with three types of connector cable and a ferrite coupler for connecting to different types of radios.

Personally, I like my TG34 (DE31MS equivalent).  Though I have *no* experience with this model – as it is new – this is the type of antenna users either love or hate.  My TG34 and the equivalents will amplify everything, including noise, but it has helped me make inaudible or barely audible signals audible.  It’s inexpensive, portable, easy to deploy and store (great for travel) – but it’s really geared towards the SWL hobbyist who can’t invest in, or erect, something bigger and/or more expensive.

The biggest advantage that I can see with this new model: the antenna has three types of connections including BNC & RCA sockets.

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

Anon-Co notes that they expect to launch this product in December 2019. If you happen to grab one, consider sharing your review here on the SWLing Post!

People Are No Longer Dependent On Radio (really?!)

Credit: St. Louis Public Radio via RadioINK.com

As the regular readers know, this site is not purely and entirely shortwave radio-centric … we enjoy all radio.

I don’t think we’ve mentioned this web site before, but I recently ran across this article on RadioINK:

People are no longer dependent on radio.

That’s what St. Louis Public Radio contends with the launch of its new podcast, The Gateway, another short (7-15 minutes), daily news podcast. Here’s what they had to say about the new show

Being a radio buff – or shall I say an ALL radio buff – I cannot fully comprehend that “people are no longer dependent on radio”. But I do acknowledge that technology has allowed us to manage our time better. And having a local podcast of news does appeal to many (yes, I suppose even to me at times).

It’s a very short article – three paragraphs – but I challenge the readers to comment: are you no longer dependent on radio? Okay – that’s a loaded question to this audience – just look at this post within the past 24-hours! But we’d also like to know: is there anything in your area, like this article describes of St. Louis Public Radio, where your local stations are turning to podcasts or other means to reach and/or expand their target audience?

Thanks in advance for your comments.

Intense Solar Bursts on 20 & 25 MHz

Yet another Space Weather note and how Space Weather and radio are intersecting yet again – yesterday & today!  Yesterday Thomas Ashcraft – mentioned recently in this postrecorded the outbursts.

From http://spaceweather.com

INTENSE SOLAR RADIO BURSTS: Big sunspot AR2740 is turning toward Earth and emitting loud bursts of shortwave radio static. A remarkable outburst yesterday was rare in both its form and intensity, exceeding even what observers have detected during Solar Maximum …

UPDATE: Rob Stammes of Lofoten, Norway, has detected even more bursts on May 7th. The sun continues to be “radio-active.”

For the complete story, go to spaceweather.com.

Active sunspot returns

(Source: Spaceweather via Troy Riedel)

This weekend, old sunspot AR2738 is returning from a two-week trip around the farside of the sun. After re-appearing late yesterday, the sunspot quickly produced two CMEs (coronal mass ejections), signalling that it may be even more active than before. Last month when it crossed the face of the sun, AR2738 crackled with low-level flares and strafed Earth with loud shortwave radio bursts.[…]

Big Sunspot Produces “Ocean Surf” Sounds on Shortwave

Though sunspots have been rare this year, Sunspot AR2738 has been producing bursts which have been heard as radio static – that sounds like “ocean surf” – on shortwave.

This was posted early this morning at spaceweather.com – along with a recording:

If you have a shortwave radio, you might have heard some unusual sounds this week. Big sunspot AR2738 is producing strong bursts of radio static. “They sound like ocean surf,” says Thomas Ashcraft, who recorded this specimen on April 13th using an amateur radio telescope in New Mexico:

“Human Magnetoreception”: Can Humans Sense Magnetic Storms?

Can our brains sense Geomagnetic Storms?  Do we have an “internal radar” that tells us when the sun is active?

Brain waves respond to Magnetic Fields (Credit: Earth to Sky Calculus)

I ran across this article this morning posted at http://SpaceWeather.com

CAN HUMANS SENSE MAGNETIC STORMS? Close your eyes and relax. Daydream about something pleasant. In this state your brain is filled with “alpha waves,” a type of electrical brainwave associated with wakeful relaxation.

Now try it during a geomagnetic storm. It may not be so easy. A new study just published in the journal eNeuro by researchers at Caltech offers convincing evidence that changes in Earth’s magnetic field can suppress alpha waves in the human brain.
