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.

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.

Sony ICF-SW100: Whip vs. DE31MS active vs. Sony AN-LP1

Guest Post by: Troy Riedel

It’s been a while since I posted a video on my YouTube Channel (but I’ve gotten the urge to make several more videos as I’ve been recently comparing my equipment – 16 portable receivers & many antennas).

I try to tune in to Radio Prague via WRMI on many weekday East Coast USA mornings from 1300-1325 UTC. Yesterday I encountered bad propagation but today was much better.  The video linked to this post is from today – 30JAN2019 recorded around 1310 UTC.

[Sorry, no tripod for this one]

People often ask, “are amplified antennas helpful” – as evidenced by this post from Thomas from a few years ago.

Without repeating the debate, just take a look at this one example.  As stated, reception was pretty good today off the little whip – but – there is an improvement using an amplified antenna.  My question: is there a difference between the two amplified antennas?  And if so, is the difference worth the price?

My TG34 is a clone of the DE31MS – purchased from Tquchina Radio & Component (ebay user: Tao Qu … they used to have an eBay store “Sino Radios” if I recall, but they stopped selling on eBay when the Post started cracking down on shipment of batteries – I actually exchanged an email with a frustrated Tao Qu when they closed the store).

I paid about $21 if I recall for my TG34 (the DE31MS is available today on eBay for as little as $17.28).  I paid over $100 for the Sony AN-LP1 (out of production now and can be listed for as high as $300 on eBay).  So … $21 versus “over $100”.  Is there a difference – and if so – is it 5x the difference – 5x better?!

You be the judge.

P.S. Just a quick slightly over 1-minute video recorded inside my house (sitting in my breakfast nook) … typically “okay” reception but not my usual Listening Post.
