Many thanks to SWLing Post contributor Dennis Dura for sharing this fascinating Nuts & Volts article exploring the history of FM radio in American automobiles. While AM dominated dashboards for decades, FM began to make its way into U.S. cars in 1958, slowly changing how drivers listened to music and news on the road. The piece traces the industry’s hesitations, the technical challenges, and the cultural shift that followed. You can read the full story here:

Retekess V112: An Ideal Ballpark Companion
by Aaron Kuhn
In my previous post for SWLing Post, I suggested the characteristics of an ideal ballpark radio and considerations for radio selection. While researching that post, I came across the Retekess V112 which ticked a lot of the boxes I recommended – compact, cheap, unobtrusive.
The Retekess V112 has indeed turned out to be a compact, affordable, and unobtrusive companion for enhancing the game-day experience at the ballpark. Priced at a consistent $15.49 on Amazon [SWLing Post affiliate link] for over a year now, this little red (or Gold) radio has exceeded my expectations.
Unboxing and Accessories (and what to replace):
While the physical packaging is a distant memory to me, the V112 comes with earbuds, a neck lanyard, and a Micro-USB charging cord.
- Earbuds: While included, the provided earbuds are notably uncomfortable and were quickly relegated to the recycling bin. My ears are not your ears of course, and they might be salvageable with interchangeable eartips if you have some lying around, but it’s highly recommended to bring your own comfortable earbuds or headphones. This is especially important as the headphone wires double as the antenna, and reception can vary significantly between different pairs of headphones based on the cable. My older Apple EarPods offered good comfort and reception, while Sony MDRE9LP’s performed poorly. Experimentation of pairing the radio with low-cost IEMs would be an interesting project.
- Neck Lanyard: Surprisingly, the neck lanyard is the hidden gem of this package. It allows the radio to hang around your neck, keeping your hands free for hot dogs and foul balls.
- Micro-USB Charging Cord: While USB-C would be a welcome modern update, the included Micro-USB cable is understandable given the radio’s price point and older engineering. It’s hard to complain about the cable-port standard chosen when they give you the cable you need, and you probably have multiple other Micro-USB cables kicking around in storage boxes and drawers already.
Portability and Power:
- Size and Weight: The Retekess V112 truly shines in its portability. Weighing 45 grams (0.1 lbs) and measuring 3.3 x 1.8 x 0.5 inches, it’s so small and lightweight that it’s easy to forget you’re carrying it, and easy to lose it in your pocket (like I have done multiple times!) This weight is even more impressive given the battery is built-in. I like to leave my earbuds plugged into it and wrap them around the radio body for transport, producing a tidy, tiny package of everything I need.
- Battery: Battery life is another strong suit – I have yet to accidentally run it down, even forgetting to charge between games. I typically throw the radio on a battery bank on the way to the game, or shortly before the game, and have never run down the 500mah battery. I can’t find a stated battery life, and due to my experience really can’t estimate a runtime besides “long enough for extra innings.”
Features and Functionality:
- Antenna: While relying on the headphone cable for an antenna does impact reception, it eliminates the bulk and vulnerability of a traditional antenna whip. This helps to make the radio instantly pocketable and prevents accidental seat-neighbor-pokes or damage. There’s nothing fancy such as selectable bandwidths to really help you out here, so you’re either going to have usable reception or you won’t.
- Power/Mute Button: The power button cleverly doubles as a soft-mute, perfect for cutting out commercials between innings. A quick button tap when the last batter is out mid-inning mutes until you see the next batter up, and returns the previously set volume quickly.
- Keypad Lock: The keypad lock function is invaluable for setting the desired volume and then tossing the radio in your pocket or letting it hang from the lanyard without accidental button pressings changing stations or volume.
- Presets / Direct Frequency Entry: The lack of a number keypad for direct frequency entry is a minor inconvenience and my only real complaint, but in reality it’s lack of preparation. The radio does offer presets, making it easy to save your preferred stations before heading to the game – as long you remember to do so.
Future Wishlist:
If any radio manufacturers are out there listening (get in touch, Retekess or Tecsun!) I still think there’s a few features that would make an even better ballpark radio as discussed in my article from last year:
- Bluetooth Headphone Support: There are a number of small radios on Amazon that advertise themselves as having “Bluetooth”, but when you dig deeper the feature just turns the radio body into an external speaker to your phone/tablet/laptop. The exception to the rule is the Prunus J-618 which claims actual bluetooth headphone support. Bonus points to manufacturers – allow two sets of paired headphones to be driven simultaneously. Finding comfortable Bluetooth earbuds is way easier these days at retail than finding a pair of wired earbuds, and you probably already own a pair to your liking.
- Replaceable Parts: Implementing Bluetooth headphone support is going to require the move to an external antenna, and with that I’d love to see an antenna that can be easily replaced if it snaps off / is broken. I’m pro-repairability on electronics, so it would be great to see parts kits available at a small cost up-front with the radio to increase the likelihood the device lasts for years. Think antennas, plastic trim/doors, clips, lanyards, etc.
- Selectable Bandwidth: I’d pay a little more for a radio that has a selectable bandwidth feature on both FM and AM. Legible commentary for a ballgame doesn’t require a very wide bandwidth, and this would go a long way towards turning an unstable/fringe signal into something more enjoyable. I’ve made use of bandwidth selection on Tecsun radios at the ballpark in the past and this is a sorely missed feature.
- USB-C Charging: It’s 2025 – the world has moved to USB-C. Any device worth its salt these days should include a USB-C charging port, with actual proper USB-C PD support – none of that hacked up USB-A to USB-C junk.
- Multiple Mounting Options: The lanyard on the Retekess V112 is great, what would be even more fun is some kind of clip that could attach to a stadium cupholder, or be attached to a seat in some fashion. Being able to strap a radio somewhere with bluetooth headphone support would be the ultimate convenience.
Conclusion:
For under $17 delivered to your door, the Retekess V112 is a great investment for live baseball enthusiasts. This radio has consistently enhanced my enjoyment of baseball games with its portable size, performance, and ease-of-use.
At $25, the Prunus J-618 looks like it might be a contender to the Retekess V112 throne and is one I’ll likely be checking out in the future. The Tecsun PL-368 is an attractive proposition for a ballpark radio, but in my mind provides more radio than you need, at a price-point ($75-$100) where I’d be afraid of breaking it or misplacing it in a ballpark environment.
For what it is, I’m not sure there’s much else that can compete at this price with the Retekess V112 for a low-cost, turn-key solution to live baseball play-by-play.

Public Broadcasting Cuts Hit Hard in Remote, Rural Communities
Many thanks to SWLing Post contributor Richard Langley for sharing a recent CBC article that explores the real-world consequences of funding cuts to public broadcasting in the U.S.: Trump-era plan to cut U.S. public broadcasting could hit rural communities hard
While discussions around federal budgets become politicized, it’s important to step back and examine the tangible, local effects such changes will bring — especially in rural and underserved communities where over-the-air (OTA) public radio may be the only consistent, reliable information lifeline.
One such community is served by KSKO 89.5 FM, a public radio station based in McGrath, Alaska, and operated by longtime SWLing Post friend and contributor, Paul Walker. KSKO serves villages across the Upper and Middle Kuskokwim region, many of which have no access to high-speed internet or even cellular service. As KSKO’s press release puts it:
“The U.S. House of Representatives has approved a plan […] to rescind $9 billion in previously allocated federal funding. This includes a devastating $1.1 billion cut to the Corporation for Public Broadcasting (CPB), effectively eliminating all federal support for KSKO Radio.
As a result, Kuskokwim Public Broadcasting Corporation will begin scaling back operations in a way that allows us to remain on the air for as long as possible.”
This is not an isolated case. Here at SWLing Post HQ in Swannanoa, North Carolina, we’re still dealing with the aftermath of Hurricane Helene, which caused massive infrastructure disruption across the state. When systems failed in the aftermath of the storm (read one of my journal entries here), over-the-air radio stepped up.

A photo of one of the many sections of our mountain road that was washed away in the aftermath of Hurricane Helene.
According to Ele Ellis, CEO of Blue Ridge Public Radio (BPR), (quoted in the CBC article):
“We hear stories upon stories of people telling us, ‘OK, well, we got a crank radio or we had a crank radio, and we knew you’d be on.’ […] Some would crank up the volume and put the radio on a mailbox, and neighbours would gather to listen… That’s what they had to do to get information that was going to help them live.”
Having grown up in rural western North Carolina myself, I can personally attest to how vital BPR is to so many remote communities. For some, it’s the only station they can receive. If CPB-funded stations like BPR and KSKO lose their transmitter sites due to budget cuts, that critical connection vanishes — not just news, but local announcements, weather alerts, and emergency communications.
Whether or not one agrees with the politics behind these decisions, there is a real-world human cost of eliminating public broadcasting support. While PBS and NPR will certainly survive, it’s the small rural member stations — the ones that reach into mountain hollows and villages across the tundra — that go silent.
We encourage readers to support their local stations (like KSKO and BPR) if they’re able, and to advocate for the preservation of public media access in remote communities.
Combined with recent, severe cuts to the National Weather Service (which has real-world impact), these public broadcasting reductions represent a dangerous erosion of the tools we depend on during times of crisis.
For rural America especially, it’s a recipe for turning natural disasters into human tragedies.

Surprise Russian FM Signals in Southeast Finland
Many thanks to SWLing Post contributor Markku for sharing this Yle News story about an FM propagation opening along Finland’s eastern border. On a warm July morning, residents of Lappeenranta suddenly found their radios picking up multiple Russian FM stations—some from as far away as St. Petersburg, over 200 km away!
The cause? A temperature inversion and high-pressure system.
WA2XMN Revives Armstrong’s Legacy with 90th Anniversary Broadcast on 42.8 MHz
Many thanks to SWLing Post contributor Conrad Trautmann, who shares the following guest post:
42.8 MHz WA2XMN FM Goes On The Air!
6/19/2025
By Conrad Trautmann, N2YCH
Stephen Hemphill, WA3ZAE, the owner of Solid Electronics Laboratories, fired up a vintage FM tube Phasitron transmitter on 42.8 MHz to put WA2XMN on the air at exactly 12:30 pm EDT today from the famous Armstrong Tower in Alpine, New Jersey. “W2XMN” was the call sign of Edwin Howard Armstrong’s experimental FM station that went on the air in 1936. “WA2XMN” is the official FCC call sign for the station Hemphill constructed with the cooperation of the tower site owners to commemorate Armstrong’s contribution to radio, Frequency Modulation.
Hemphill explained that he attended a Society of Broadcast Engineers meeting that was celebrating Armstrong’s accomplishments, which sparked the idea of going on the air again on that original frequency. He thought it would be perfect to aim for the 70th anniversary of the first public broadcast of wideband FM. That anniversary celebration and broadcast was held on June 11, 2005. Today’s broadcast marks 90 years since that first FM Broadcast and 20 years since the commemorative event.
Hemphill built a transmitter based on the design of a General Electric BT-1-B, but on the lower frequency than what we now know as the standard FM band. Once turned on, the transmitter made 250 watts with no problem with a little headroom to spare and after warming up and settling in, had less than one watt reflected into 400+ feet of 1 ¼” transmission line into a vertical “ringo” antenna on the top, Western facing arm of the famous tower.
The audio broadcast today was mostly replays of the 70th anniversary event recordings. A temporary studio was set up in the tower site office building. The event was also streamed live over the internet.
The main audio mixing console used was a Gately Electronics Attache Case six channel mixer. Audio processing was done with a vintage Orban Optimod 8100A.
During the event, a web site address for enthusiasts to provide reception reports was given out. While we don’t have those reports yet, I contacted an amateur radio friend who was able to hear the station clearly 61 miles away in Ronkonkoma, NY on the eastern end of Long Island. That’s pretty good coverage for 250 watts!
Coupled with the special event broadcast was the annual picnic gathering of the New York Chapter of the Society of Broadcast Engineers, Chapter 15. Roughly 45 people attended and in addition to seeing the WA2XMN transmitter, they also got a first hand look at a few of the old Empire State Building FM Master antenna elements. Here’s a photo of your author standing next to one for perspective. I’m 6’ 5”.
