“Music On The Move” explores portable audio technology developments over the decades

Many thanks to SWLing Post contributor, Ed, who writes:

Last night on my bedside radio I heard on BBC World’s ‘The Forum’ a wonderful 49-minute piece about portable audio. Much of it covers the earliest portable electron tube radios and transistor radios, and their influences on society in different countries. Mediumwave, Shortwave and FM radios and stations are discussed, as well as evolving technologies. The societal impact of the Compact Cassette and digital audio players and recorders is also discussed. Probably all SWLing Post readers will find this worth listening to!

Cheers,

The Forum: Music On The Move

Released On: 22 Jun 2024

Many of us remember the first portable music device we owned: a transistor radio, a boombox, a Walkman or perhaps an iPod. We might even recall the songs we played on it. But we might be less aware of how profoundly audio technology developments from the 1950s to 2000s changed the ways in which we consume music and other audio outside of the home or concert venue. Transistor radios allowed outdoor sounds and noises to mix and compete with those coming over the airwaves, creating new auditory experiences; the cassette player gave the listener a cheap way of making and re-making their own playlists; and the advent of digital music players encouraged us to ‘own’ music recordings without possessing a physical copy of the audio.

Iszi Lawrence discusses the history of portable music with Dr. Annie Jamieson, Curator of Sound Technologies at Bradford’s National Science and Media Museum; American drummer and writer Damon Krukowski; Dr. Jahnavi Phalkey, science historian and Founding Director of Science Gallery Bengaluru, India; Karin Bijsterveld, Professor of Science, Technology and Modern Culture at Maastricht University; and World Service listeners.

XHDATA-608WB

XHDATA Weather Radio D-608WB

Review By Robert Gulley, K4PKM

This is my first experience with an XHDATA radio, and my initial impressions are quite positive. This weather radio has an impressive set of features and appears to be built quite solidly. I say “appears” because I have not done (nor intend to intentionally do) a drop test! But my sense of the radio is that it can withstand some knocking about while still functioning (but please do not test this theory! YMMV!).

Solar Cells

Solar cells with a twist – the cells along with the LEDs can be rotated up and down

 

LED lights

Three brightness levels for these LED lights – a nice touch!

 

 

 

 

 

Let me start with the items that impressed me.

  1. Weight. This is not a typical light-weight radio. It feels solid, has some bulk to it, and I like the feel. It weighs in at 11.5 ounces, which is comparable to the two other solar powered weather radios I own, which come in at 12 and 12.25 ounces respectively.
  2. This radio has both a torch and an LED panel, each with 3 levels of brightness. While you will not light up a room with either, they are both quite sufficient for their intended purposes. The LED is particularly useful to light up the immediate area around the radio, and on it’s brightest level puts out a good amount of light. Being LEDs, the power drain is very reasonable.
  3. The radio is powered by multiple sources of course, as is typical with today’s weather radios, but a unique feature compared to my other radios is an articulating solar cell (and LED) panel. This allows you to follow the sun for quite a while as it rotates in the sky.
  4. The antenna, while not very long, is very solid and should last a long time if not subject to abuse (and looks to be easily replaceable if something does happen).
  5. The battery is easily accessible and replaceable with the now-common 18650 rechargeable battery. (As an aside, for those who, like me, prefer to charge batteries outside a radio when possible, there are charging units available from the usual sources if you want to minimize heat and charging wear-and-tear on your radios and flashlights.)
  6. The ATS function works quite fast on FM, finding 21 stations in my very rural area just off the built-in whip antenna
  7. Keypad layout is minimal and functional. For those wanting a direct-entry frequency keypad, this radio is not so equipped. However, running through the memory channels is easily done, without multiple menu hoops through which to jump.
  8. Tuning is both a blessing and a curse (see cons below for the negatives) – the tuning can be accomplished at two different speeds, allowing for a slow tune and a bigger jump depending on how fast you turn the tuning dial. This can be particularly useful with SW, but also when manually scanning the MW band or when finding tracks on a memory card.
  9. The crank can be extended as a stand at a few different angles. I am not sure if this was intended, but it works nicely!
  10. When in SW mode, the band is displayed as you tune (i.e. 41mb, 25 mb, etc.)
Crank can act as a stand

I am not sure if this was intended or not, but the crank can act as a stand

Less impressive (but see conclusions):

  1. Tuning can be slightly erratic, making bigger jumps at times than intended. This can happen in slow mode (one click of the tuning wheel at a time), or it can happen when the tuner switches between slow and fast mode and you didn’t think you were turning it fast enough for the switch. On the plus side, there is one arrow displayed when tuning in slow mode, and two arrows when in fast mode, so it is easy to see when it has switched modes.
  2. There are rubber strips glued into slots on the bottom of the radio to give it a little more resistance to sliding, but I feel it makes the radio slight more unstable – you may disagree since the effect is minimal.
  3. Soft muting when tuning – I know this is a biggie for many folks, so I mention it (again, see conclusions)
  4. No SSB (not that I expected it).
  5. Three NOAA stations come in for me which is typical, but I do have weather radios which can receive 4 well enough to copy, so not quite as sensitive. However, two or more is adequate to catch weather forecasts for your area in case your closest station is down for some reason
  6. ATS on SW and MW was not impressive – perhaps moving too quickly? Many stations come in with good audio, but the scan did not find them. Again, YMMV.
USB and Power Connections

On the side are the input and output USB connections, along with the TF card slot.

Conclusions

I find this to be a good radio for its intended purpose – a Weather Alert radio with solar, lights, and multiple charging power options for operating, and an option for charging small devices if needed. This is not, nor should it be compared to, stand-alone shortwave radios. This is a bonus, and it works well for AM shortwave stations. That it does not have SSB is not an issue for me – I have plenty of radio options to enjoy during a power outage which are capable of SSB upper and lower sidebands.

The soft muting will no doubt bother some, but again, this is is primarily a weather and emergency radio, not a radio designed for pleasurable shortwave listening. As for the audio itself, the speaker produces a good clean sound, and there is even a type of bass boost which helps the audio even more. AM, FM, and SW stations sound good, and I find the audio to be quite strong out of this compact unit.

A replaceable/removable battery is a real plus for me both in terms of charging and for popping in a fresh battery while charging a drained battery. I like having backups for my backups, so this is right down my alley.

The unit is a good size, compact but solid, and has all the useful controls easily reached/manipulated. The antenna is solid, the LED lights are a nice touch, and it is a radio I believe could be counted on when needed. (Oh, and it is reasonably priced as well!)

As always, these are my personal, honest opinions. While the XHDATA folks approached me for the review and sent a unit to me free of charge, I always call it as I see it, good or bad.  I happen to think this radio is a keeper!

Carlos’ Shortwave Art and recording of Vatican Radio (May 13, 2024)

Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares his radio log art of a recent Vatican Radio broadcast.


Carlos writes:

Part of Vatican Radio news bulletin, in Portuguese, about destructive floods in Kenya (translation below):

Here’s a translation:

“… caused havoc across the country, the Kenyan Bishops’ Conference expressed its deep sympathy and solidarity with all those affected by this natural disaster. In a press release dated May 7, and cited by Agência Cisa África, Dom Maurice Muhatia Makumba, Archbishop of Kisumu and President of the Episcopal Conference of Kenya, highlighted the urgent need for collective and compassionate action in response to the crisis. . In recent weeks, Kenya has seen incessant rains that have led to catastrophic flooding, resulting in loss of life, widespread displacement of people and considerable material damage. Families struggling with the consequences of this catastrophe find themselves in dire circumstances, with the rains worsening their situation. In a moving statement, Bishop Muhatia invoked the words of Matthew, chapter 25, highlighting the fundamental importance of providing help to those in need. He expressed his sincere condolences to the families who lost their loved ones and called for solidarity in prayer and support during this period of pain. The prelate highlighted in particular the tragic incidents, including the sinking of a boat in Garissa, the loss of lives while crossing the river in Makueni and the displacement of residents in Mai Mahiu and Kisumo. Kenyan prelates urged authorities at all levels to prioritize disaster management efforts, mobilize resources effectively and ensure swift action to save lives and protect assets. In this regard, the Kenyan bishops’ conference launched an appeal in all dioceses for the support of Christian faithful and Kenyans of good will. Contributions are being channeled through local parishes, diocesan offices, and assistance services designed to provide help to those in difficulty. Archbishop Muhatia further highlighted the importance of collective effort and divine grace to overcome the challenges posed by the floods, supporting unceasing prayer and tireless efforts to alleviate the suffering of affected communities, echoing the teachings of Christ, demonstrating compassion and generosity towards those in need. In conclusion, Bishop Muhatia appealed to all Kenyans to demonstrate God’s mercy through their actions during this period of distress. The conference reiterated its commitment to stand in solidarity with those affected and called for continued support and assistance to restore hope and rebuild communities devastated by the disaster. As the nation grapples with the devastating impact of the floods, the message resonates as a beacon of hope and compassion, calling on everyone to come together in solidarity and reach out to those in need.”

Why I DX?

…… or as all the locals call it, “Talking to the aliens at the International Space Station.” You might ask yourself, what in the world? Well, I live in a very small, remote bush Alaska village, and my DXing is done outside, yes… even in winter. I’ve been here 3 1/2 years now, and when I first got here, 2 or 3 people seriously thought I was trying to talk to aliens.

I’m kinda “late” to the DXing game… starting seriously in 2014 when I was 30 years old but dabbling in it as young as 5th grade when I thought it was SO COOL I could hear WOWO 1190 Fort Wayne, Indiana, and KDKA 1020 Pittsburgh, Pennsylvania, in central Connecticut clear as a bell at night.

In like 6th grade, my uncle gave me a beautiful tabletop Firestone radio and hooked up a long wire about 100 feet long from my bedroom window to a tree in my yard… wow, WLW 700 Cincinnati every night in Connecticut, I was hooked!

When I discovered how radio waves traveled great distances and at the same time, listening to a really fun oldies station, Big D 103… I was like “This is for me,” and started my quest and desire to work in radio… something about speaking into a radio and being heard 10-20-30-40-50 miles away fascinated me to the umpteenth degree.

That was really before the internet, but I’m 40 now and have been working in radio for 20 years, still DXing mostly every day. Most of my money is spent on food and DXing accouterments.

I’ve had people ask me, especially those who in the small Alaskan village I’m in, “Why, especially in cold weather do you do this?”

I tell them a couple things… I moved up here in part for the hobby, so I’m going to take every advantage I can. There’s too much electrical noise for me to do it from home.

Sitting out here at the park is my “Happy place,” especially after a particularly trying day at work for any number of reasons; this is my place to escape and decompress while being by myself… peace and quiet.

Plus, it’s the magic of how these radio waves travel that got me interested in working in radio. I’ve never lost that childhood magic and wonderment of radio waves and how things work, even though I’m 40. I’m really 40 going on 12 anyways.

I like how when I know when and where to listen, I can hear some amazing things up here in Alaska that many people wouldn’t expect I’d hear at all or as well. There’s something to sitting at the park, especially on a nice summer afternoon, and getting a solid S9+60 or better signal on Radio Nacional de Amazonias 11780 kHz from 12,400 km, opening my radio’s audio filter to 8 kHz bandwidth, and listening to a football match, sounding like I’m right in the stadium or tuned to their music/listener interactive show “Eu de Cá, Você de Lá” hosted by Mauricio Rabelo and sound like I’m tuned in on a 50,000 Watt AM from 50 miles away.

And no, I don’t understand 99.5% of Portuguese, and I only know a few basic words I can speak. I’m way way outside of their target area, but RNA from Brazil being anywhere from “listenable” to “Banging in like a ton of lead bricks” is very common because I’m in just the right place for it.

And I do it all without the internet. Well, OK… I do use the schedule from www.eibispace.de.

All of that combines to fascinate me. And yes, remember… I know how it all works, and I still do a lot of internet streaming, but radio waves continue to fascinate me because it takes some twisting of knobs and fiddling with the antenna to get it just right.

And the fact that it just works and travels through the air is amazing to me.

I live in McGrath, Alaska, which is a community of 275 people that is 355 km NW of Anchorage, completely off the radio system. I manage the daily operations of KSKO Public Radio, an NPR member station, with 8 FM transmitters spread across several hundred miles of Alaska. You can also catch me every Friday on Spaceline Bulgaria’s 5900 kHz transmitter across Europe 2100-2200 UTC with a live relay of my very local KSKO Lunchtime show.

I moved up here for the job, but also knowing that from past experiences living 125 miles north of here 7 years ago, that DX would be amazing. And it’s far exceeded my expectations along with the knowledge and expectations of some of my broadcast engineer friends and station owner friends!

Kim Elliott: Why We Need “Shortwave 2.0”

Many thanks to a number of SWLing Post contributors who share the following article written by our friend Kim Elliott for Radio World:

Why We Need “Shortwave 2.0”

by Kim Andrew Elliott

Debate about the future of shortwave broadcasting focuses on the correct observation that shortwave listening is no longer a mainstream activity in most of the world.

The future of shortwave broadcasting — “Shortwave 2.0” — will not involve any revival of those large audiences. Instead, it will be an activity of communications enthusiasts and professionals. They would comprise a reserve corps able to relay information to larger populations in their countries when newer media are blocked or otherwise become unavailable.

The beginning of the end of “Shortwave 1.0” was described in “Shortwave Broadcasting Begins Its Long Slow Fade,” an article I wrote in the 1995 World Radio TV Handbook. I noted the elimination, in the post-Cold-War media environment, of shortwave broadcasts in some languages, as well as some entire transmitting sites, e.g. Trans World Radio on Bonaire and Far East Broadcasting Company in California (KGEI). In my (then) role as audience research analyst at the Voice of America, I listed examples of declining shortwave audiences.

The really big chunk fell from the shortwave glacier six years later, when BBC World Service ended its English broadcasts to North America. In the following years, other international broadcasters followed, first dropping shortwave to North America, and eventually to other parts of the world. The aforementioned 1995 World Radio TV Handbook listed 27 European countries with English broadcasts on shortwave to North America. Now only Radio Romania International has shortwave English to North America.

The exodus from shortwave (for both international and domestic broadcasting) was due to competing media, including relays on FM stations in the target country, satellite broadcasting (mostly television) and, especially, the internet.

For the audience, internet content is easier and more reliable to receive. It also allows content to be received on demand, and text or video in addition to the audio to which shortwave was restricted. As an audience researcher, I could see in the datasets that audiences for international media were migrating from radio to internet-based media. [Continue reading at Radio World…]
