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.”

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.
