Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Ron Chester, Benn Kobb, Chuck Rippel, Pietschman, Dennis Dura, and Dave Zantow for the following tips:


“Market Makers” Want to Expand Their Use of Shortwave (Radio World)

The FCC seeks comments on a proposal to use HF spectrum for financial data

The FCC is taking public comment on a proposal to revise the rules governing the frequencies above 2 MHz and below 25 MHz.

The Shortwave Modernization Coalition thinks the 2-25 MHz band is underused and wants to use it for the long-distance transmission of time-sensitive data from fixed stations. The users would be companies working with certain kinds of financial transactions; the proposal would prohibit voice transmission and mobile operations.

The firms in the coalition are “market makers and liquidity providers” for exchange-traded financial instruments.

This high-frequency trading industry has in fact been using shortwave links for several years to send trading data between U.S. and foreign exchanges, but it has done so under experimental authorizations. [Continue reading…]

QTC: I Have a Message for You (Archive.org)

Many thanks to Bill Pietschman who notes that the book “QTC: I Have a Message for You” has now been published on Archive.org for all to read and download free of charge. Bill writes:

I knew Ray Redwood, and besides being a Professional radio operator, he was indeed a Ham’s Ham. You will find here not just the story of radio, but a detailed analysis of the Titanic, from a radioman’s point of view. Part documentary, part autobiography, and part technical, it’s a great read. I’m so glad that his work has been preserved here. Future radio historians will, I am certain, find it to be a valuable record of the Ship Radio Officers Era, and Ray’s insights at the dawning of the Global Maritime Distress and Safety System as we have today which utilizes satellite technology.

The Golden Years of Shortwave Listening (YouTube)

There was a time, some 50 years ago when cell phones didn’t exist and computers were only owned by large corporations, that people learned of the world around them by listening to shortwave radio. This is a journey back to that time to hear the sounds and see the correspondence from shortwave stations from all over the world. Sit back, listen and enjoy!

RADDY RF320

A review of the Radioddity RADDY RF320

(Almost) All-in-One in a Box

By Robert Gulley K4PKM

The RADDY RF320 is a rather attractive, if not slightly curious-looking radio, which breaks from the more recent offerings from Raddy and other small portable radios. Compact, but not pocket-sized, the radio comes in at roughly 3-3/4” x 4-1/2” almost square (not counting the tuning dial on the side, the slightly raised antenna on top, or the light on the side).

The radio can receive AIR, FM, VHF, MW(AM), SW, and Weather Band signals. (For those interested in the U.S. Aircraft Band, this model does feature AM modulation, so civil aircraft can be monitored). While the radio does have AM SWL bands, there is no SSB reception. SW bands run from 90m thru 13m, with tuning in 5kHz single steps and scan mode.

IOS APP

This is the IOS version of the Bluetooth App. Clean layout, keyboard frequency entry and radio control

There are four tuning methods if the user includes the Apple or Android app which feature direct keyboard entry in addition to the three modes found on the radio. As a rather cool feature, the QR scan codes are imprinted on the back of the radio for both IOS and Android apps, so if you are out and about you can easily download the app to your phone or tablet. A nice touch! No having to type an esoteric web address or search for the app. (I tried both codes and they worked just fine.)

In addition to the usual tuning methods, the RF320 has what they refer to as “fine tuning knobs” on the side and front of the radio, with the knob on the side a continuous tuning within a band mode. The knob on the front is something, well, a bit unusual. While it is a fine-tuning knob, it is designed to manually tune in search mode. A little explanation is in order.

Most radios which feature a search mode, this one included, allows the user to long-press a directional button or rotate a tuning dial a given distance to activate a search mode. When the typical radio finds a station, it may stop momentarily or completely, depending on the design. The search modes in this radio all do the latter- they stop completely. However, unlike most radios, this radio features three different methods of searching. The up/down arrows can be pressed for a second or two to start a search, or the tuning knob on the side can be rotated some distance quickly, and a search will begin. The third method is the tuning knob on the front. By manually turning the knob the radio will attempt to find the next signal within the current band or sub-band without stepping through each 5kHz frequency (of course it is doing this internally, but it is not really obvious visually).

For example, when in FM mode, this tuning method will jump to the next usable station. In SW mode, in a given sub-band (13m, 90m etc.), this knob will jump to what it senses as the next usable signal, rather than scanning every 5 kHz as done in the other modes. This allows for a very quick check of a given band (or sub-band).

As with any search mode on a radio like this, there will be false positives. Life is not fair – static crashes and birdies and digital signals can all fool a radio’s search mode.

Bass Boost, Back Lights, QR Codes

Changing lights, Bass Boost, and QR Codes for Downloading Android or IOS Apps

The radio features excellent sound for its size, with a rather large front-facing 5W speaker, and a bass port on the back. I can crank the volume louder than I would ever want in a room and the audio remains clear.

Reception on all the bands is quite acceptable, keeping up with typical portables its size, and even ones with longer antennas and larger ferrite bars for AM reception. This is not a Panasonic RF-2200 or a GE Superadio, but for what it is designed to do, it does quite well.

The radio also has an abundance of memories, allowing you to save up to 995 stations, including 199 each for AIR, FM, VHF, MW, and SW.

Like some of the other radios from RADDY, this one has Bluetooth connectivity to Android or IOS for the App functionality, and takes a TF memory card to allow for playing music, podcasts etc., as well as having a flashlight and S.O.S. capability. There is a headphone jack and Aux. jack, as well as a USB-C charging port for the replaceable 18650 2000mAh battery (whoo-hoo!). Sleep mode, timer, wake to music and six sound effects are added features.

Lights, lights, and more lights. ‘Nuff said! (See images)

Pros and Cons

Pros: Good audio, AM receive for aircraft band, good sensitivity, multiple ways to tune, excellent App connectivity on my iPhone with direct frequency entry, good form factor, unit seems solid, replaceable battery, 18-month warranty(!), carry strap, aux. input to allow the radio to act as a speaker, included wire antenna and charging cable.

Cons: Telescoping antenna a bit frail, side tuning knob feels a bit wobbly (but I experienced no problems), back colored lights seem unnecessary (nit-picking and just a personal opinion, YMMV), EQ effects seem weak as only a few seem to make much of a difference (and not needed in my opinion, since the standard audio is quite good), no SSB (not a problem for me but will be a deal-breaker for some), and typical for this type of radio soft muting while tuning.

Conclusion

This is a good, solid radio with lots of options in terms of modes and bands, as well as extras which make it an almost all-in-one radio. This is a radio one could take to the beach or a park, or use in an office or on the coffee table or night stand. It is small, portable, packed with features, and controllable from your phone or tablet. At a price well under $100 ($71.99 special price from Radioddity at the time of publication), this may well be the radio you have been looking for to fill that portable niche!

BBC Kranji shortwave relay station to close July 16, 2023

Many thanks to a number of SWLing Post contributors who have reached out about a report on AWR Wavescan regarding the closure of the BBC Kranji relay station in Singapore.

I contacted AWR Wavescan host, Jeff White at WRMI, and asked for any details he might have since I could not locate any press release from the BBC or Encompass.

Jeff shared the following notice from AWR Wavescan:

Another shortwave station is about to go off the air for good also. Encompass TV reports that the BBC relay station that Encompass operates in Kranji Singapore will cease operation as of July 16th, after many decades of service. This will result in a reduction of BBC English transmissions to South Asia. Some transmissions from Kranji will be moved to other shortwave transmitter sites.

Many thanks for the info, Jeff.

We’ll post more details about the closure as they become available.

Op Ed: “OK, but why shortwave?”

Many thanks to SWLing Post contributor and host of Underground Sounds, Kelsie, who writes:

Why Shortwave?

by Kelsie

A question I’m regularly asked when talking about our radio show, and radio in general, is why choose independent radio rather than publishing a podcast or streaming playlist?
The answer is not a simple one, but I feel that it’s a powerful one.

Streaming services have made it far easier for new and independent artists to publish music, but publishing is only the first step in exposing new music to a potential audience. The age old problem faced by artists and publishers since the commercialization of music, remains – how does an artist or label get their new music heard?

The sad truth is that the vast majority of artists publishing their music on streaming services such as Spotify, Apple Music, or Tidal, etc., will not get what they’re really looking for, and that’s exposure.

Streaming services present content to their users based on a limited form of mathematical artificial intelligence known as an algorithm. Algorithms work by correlating searches by users with the content of their saved playlists. If users do not know that those new songs exist and have not searched specifically for them, the streaming algorithms will not have enough data on the new releases to suggest them to a wider audience who might like them. As a result of this, people who use streaming services are not exposed to a variety of musical styles and genres, unlike those of us who grew up when terrestrial radio was the dominant format.

While terrestrial radio may still be unencumbered by algorithm-generated playlists, commercial FM and satellite radio have effectively homogenized them over the years, resulting in a similar impact to musical variety. There was a time when radio stations used to allocate time slots for shows hosted by DJ’s that played different genres and styles of music on the same frequency. Since about 2010, the DJ format has become practically extinct.

Most radio stations today play a limited selection of songs and artists based on agreements with the traditional recording industry, resulting in very little variation from station to station at any given time of day. Both frequent listeners of FM or satellite radio can attest that the same songs and artists are played daily, even if they’re played in a different order, and even switching from one station to another during a song will oftentimes result in the listener hearing a different song by the same artist on the other station. This is only getting worse now that the majority of radio stations within the United States are owned by only two major corporations.

 

The lack of musical variety listeners are exposed to on commercial radio and streaming services lead me to the first part of my answer:

Independent radio is not subject to the homogeneity of commercial radio or streaming services.

This is largely due to the fact that instead of playlists or algorithms, independent stations are usually focused on the communities they serve, and tend to still produce individual shows tailored to different genres and interests. Tuning in at different times of the day exposes listeners to music they just wouldn’t have heard on other formats. Not everyone will like the same songs or artists, but there is usually something for everyone and a priceless opportunity to expand one’s musical horizons.

An explanation of this usually leads to the question, “OK, but why shortwave?”, or, “Isn’t shortwave dead?”

Here is where answer is is a little more complicated.

I’m sure, at least for myself, part of the decision to utilize shortwave broadcasting is based in the nostalgia of listening to broadcasts from all around the world as a child at the peak of the Cold War in Europe, hearing songs in languages I did not understand, often in keys and rhythms unfamiliar to a Western ear, and my particularly fond memories of listening to relays of Casey Kasem’s weekly Top 40 show from back home. As a former musician myself, and an avid shortwave listener who likes to restore vintage radio receivers, I still have almost that same level of excitement when I hear musical styles that I haven’t been exposed to before, and I want to share that with anyone in the world with an ear to listen.

This being said, the most important component of my answer comes down to accessibility.

Shortwave broadcasting is accessible. While independent radio may provide the only remaining viable format for exposing listeners to music from outside the corporate mainstream, independent shortwave radio potentially allows listeners from anywhere in the world to listen to music that they might be actively prevented from hearing in their own countries through various means, such as internet censorship or national broadcasters who only play what their governments mandate or allow.

As Geddy Lee from the band Rush used to sing, “One likes to believe in the freedom of music”.

I know that we certainly do, and I’m sure our opinion is shared by many of the fine music broadcasters on shortwave radio right now. From some of the more notable national broadcasters who pepper their broadcasts with music from their countries, to independent broadcasters such as Over The Horizon Radio, Alt Universe Top 40, VORW, Cruisin’ The Decades, Memphis Weirdos, Pop Shop Radio, Laser Hot Hits, This Is A Music Show, Texas Radio Shortwave, and many, many more who play music that terrestrial or satellite radio won’t play.

While shortwave radio is also going through somewhat of a renaissance right now, in large part due to the current dire situation in Eastern Europe, I think it’s more than that. I feel that large part of it is boredom and apathy with mainstream radio and the coldness of streaming services.

Whatever the reason, what better time than now to listen to shortwave stations from around the world, or even to become a part of the music broadcast resurgence yourselves?

TX Factor Episode 29

Many thanks to SWLing Post contributor, Eric (WD8RIF), who notes that the 29th episode of TX Factor was recently released. Here’s the show summary:

Welcome to our new episode!

TX Factor Calling – TX date 8th July 2023

We’re beaming (almost) live across the airwaves with microwatts of broadband energy to bring you the long-awaited show 29 of TX Factor. In this programme we increase the power to a few tens of Watts when Bob, Dave and Noel head to the Wiltshire hills with a pair of Icom IC-905 all-mode transceivers to see what can be achieved.

Bob takes the TX Factor cameras to the heart of England to the UK’s last remaining shortwave transmission station and ramps up the power to a staggering 250 kilowatts. Woofferton, near Ludlow, is the home to some venerable Marconi senders from the 1960s still beaming programmes across the globe.

Oh, and there’s a free-to-enter draw – details below.
