Raddy RF750 Plus AM/FM/SW/NOAA Radio
by Mario Filippi
I purchased one of these tiny radios several months ago. It’s my daily go-to AM broadcast band radio. So far, it performs excellently on AM. Using the rotatable ferrite antenna, I’ve received stations as far away as Chicago and Detroit at night. FM broadcast band capability is also excellent in my experience for such a small radio. As for SW, the only luck I’ve had is with powerful broadcasters when the Raddy’s telescoping antenna is connected to an outdoor ham antenna. It receives local NOAA WX as good as any other radio I’ve owned.
Raddy 750 Plus
The case is all metal, feels nice and hefty in the hand. A shade under a half-pound in weight. 3 3/4 inches high (approx. 9 cm) with attached rotatable antenna. The speaker size is exceptional for such a small radio and the audio’s very acceptable to the ear. The speaker grill can be used to tune the radio manually by the way. The fit and finish are excellent. Has a rechargeable battery with included USB charging cord. Excellently-written 25-page owner’s manual in English.
?I use the Raddy app to control the radio. You can opt not to use it though. You’ll definitely need to read the manual then, due to the plethora of options.
Raddy’s SmartPhone App Works Great
All said, since I bought this radio mainly for daily AM broadcast reception and occasionally checking NOAA weather, I’m very pleased. Price is very reasonable, mine was under $40 at the time.
Wonder if anyone else has one of these radios and what their opinion is? Thanks for reading and 73’s.
Many thanks to SWLing Post contributor Dennis?Dura for sharing this article from Radio?World, which reveals that Tesla will eliminate AM and FM tuners from its 2026 Standard Model Y and Model 3 trims—a move the National?Association?of?Broadcasters calls a “disservice to millions of drivers” who rely on broadcast radio for news, community and emergency alerts.
After Hurricane Helene devastated western North Carolina, a couple of radio broadcasters played a critical role in keeping residents informed. Now, six months later, they have taken on a new role in the recovery. Skyler Henry reports.
Having experienced the devastation of Hurricane Helene firsthand, I can confirm that this radio station, along with its FM relay, delivered crucial community updates when both internet and mobile phone services failed.?Never underestimate the power of local radio. — Thomas

Channel 6 Radio Stations
By Bob Colegrove
Even after all these years, I still find occasional surprises while playing with radios. How did I miss this one? I recently did what I thought was a definitive audit of the available FM stations in my area. Then, just the other day I happened to tune down below 88.1 (FM Channel 201). At 87.7 MHz I came across some delightful Latin music in clear stereo and proceeded to park the tuning knob there for a listen. At first, I thought I might simply have some intermodulation from a strong local station, but the stereo signal was much too clear. So, I resorted to the internet to determine what was going on. Turns out, according to their website, I was listening to DC 88.7FM in Fairfax, Virginia – no call letters, just “DC 88.7FM.”
Further investigation indicated that the station is officially WDCN-LD a low-power operator, but you won’t find it listed on the FCC FM Query site. That’s because it is something of a legacy station, a carryover from analog TV days when the audio for Channel 6 was broadcast with the carrier centered on 87.75 MHz, within the range of most FM receivers. Having discovered this, I retuned the radio slightly to 87.75 MHz and found the signal strength peaked. Wikipedia describes the history of WDCN-LD at https://en.wikipedia.org/wiki/WDCN-LD.
Of further interest is the history of so-called “Channel 6 FM radio stations.” The evolution of present-day stations is long and involved. Over several years, the FCC formed committees, requested comments, held hearings, wrote reports, published proposals, rendered rulings, and ultimately granted waivers. For the full story, see https://en.wikipedia.org/wiki/Channel_6_radio_stations_in_the_United_States. What resulted are legacy stations dating back to analog TV days which continue to operate sans video as de facto FM stations. For all practical purposes, we have a modest extension of the FM band. There are, in fact, 14 such stations currently spread across the lower 48 states. It is unlikely that the circumstances which created these stations will ever result in more stations being added. As of July 20, 2023, an FCC report and order restricted these stations to those already licensed and current licenses untransferable.
Do you live near a Channel 6 FM radio station?
Just to complete the picture, there is also officially an FM Channel 200 at 87.9 MHz, which was established in 1978, but to my knowledge is not used. Does anyone have any information on FM Channel 200?
As an historical aside, the present-day FM band, 88 to 108 MHz, is located directly between analog TV Channels 6 and 7. In 1958, to foster FM use, Regency Electronics, Inc. marketed a converter, Model RC-103, in a handsome Bakelite case, which could be attached between the antenna (generally “rabbit ears”) and the TV set. The converter contained a single transistor and was powered by three AA batteries. By tuning the TV to Channel 6, turning on the TeleVerter to FM, and rotating its dial, one effectively detuned the Channel 6 audio frequency upward, and could listen to the entire FM band. As this converter was manufactured prior to the advent of stereo broadcasting, the sound was in mono, and fidelity was limited to the audio quality of the TV. My dad bought one of these. It was connected to our Arvin 12”, B/W tabletop TV, and it served as our first FM radio for a few years. There were only a few stations at that time, mostly classical as I recall. Thus “FM” came to stand for “fine music.”

No matter where you live in the world, everyone should have a battery-powered or self-powered (hand-crank) portable radio in their home.
Recently, the pace of articles here on the SWLing Post has slowed down. That’s because I live in Swannanoa, North Carolina—a town that was particularly hard-hit by Hurricane/Tropical Storm Helene, which brought unprecedented rainfall and caused widespread destruction.
In short, our rural mountain community was completely cut off for several days. Our bridge washed out, and a critical section of road crumbled daily.
At one point, two families had to be helicopter-evacuated for medical reasons, and less than a week after the storm, the Sheriff’s department came door-to-door recommending evacuation.
Our amazing community pulled together: we cleared our road of hundreds of downed trees and made sure everyone had food, water, and supplies. We took care of each other.
Now, things have improved dramatically. After two and a half weeks without power, we’ve been reconnected to the grid. The Kentucky Department of Transportation repaired our road, making it accessible to regular vehicles again. On Tuesday, an arborist crew finally made it up the mountain to remove fallen trees from houses.
Although things are starting to feel more normal at home, the impact on Swannanoa, Asheville, and surrounding areas has been profound. Entire neighborhoods are gone, numerous businesses have closed, and several grocery stores were severely damaged.
The Communications Void
The National Guard helped us for a full day at our home. Thank you 5th Battalion 113 Field Artillery!
It’s often said that modern communications infrastructure fails us after a disaster.
I can confirm, first hand, that this is true.
The mobile phone network went offline during the storm, leaving us without service for days. Even now, three weeks after the storm, mobile phone service remains unreliable. Calls drop every few minutes.
Mobile data services at home are still down at time of posting (October 18, 2024). Internet services like cable, fiber, and DSL are mostly still out across the county. Only those with satellite internet have a connection—I’m fortunate to be one of them. Our cell tower still only supports basic voice calls and text messaging, without data or media attachments.
Radio to the Rescue
As many of you know, I’m not just a radio listener, but also a licensed amateur radio operator, and both of these hobbies became essential post-Helene.
As highlighted in an article by WIRED, amateur radio proved to be our lifeline for communication when everything else failed.
Using the local repeater (N2GE on Mount Mitchell), I was able to pass wellness checks, coordinate helicopter evacuations, and arrange supply drops for our community. I handed out a few handy talkies to unlicensed neighbors so we could stay in touch.
My wife and daughter, who are also hams, helped tremendously. While I was out with a chainsaw, clearing driveways, they acted as net control operators on our community’s simplex frequency (147.555 MHz), passing critical messages.
For that first week especially, amateur radio truly was our community’s connection to the outside world.
AM/FM Radio: A Lifesaver
Fortunately, our local TV station remained online after the storm, but few people could access it. Many people rely on cable or internet to watch TV, and in areas like ours, the digital transition over a decade ago left many without the ability to pick up over-the-air signals.
In contrast, FM and AM radio became the most reliable sources of information. Here in Buncombe County, public information and news were broadcast on 99.9 MHz (FM) and 570 kHz (AM). Both stations stayed online throughout the disaster, and the information they provided reached a vast audience. Check out this feature from CBS Evening News:
In Henderson County, the local AM station WTZQ stepped up as well. They did incredible work serving their communities post-Helene, as highlighted in a report by Queen City News:
Information Lifeline
As a presenter in the above story pointed out, everyone should have a battery-powered (or self-powered) AM/FM/Weather radio in their home.
After a disaster, you’ll rely on that radio for essential updates like where to find clean water, how to apply for FEMA assistance, what businesses are open, and when services will be restored.
Even three weeks after the storm, much of the Asheville area is still without water, so radios remain vital for getting updates.
Here at SWLing Post HQ, I shared my extra portable radios with neighbors who needed them. I used my CC Skywave SSB 2 in the kitchen window to tune into local news on 99.9 MHz and 570 kHz. I also relied on my XHDATA D-109 and CC Radio 3—they became our constant companions for information.
Many of you here on the SWLing Post are already radio enthusiasts, so no doubt I’m preaching to the choir. But let this serve as a reminder to stock up on alkaline batteries and check your radios regularily to make sure they’re fully functional. Keep spares on hand so you can lend them to neighbors if needed—they’ll never forget your generosity.
And don’t assume your area is safe from natural disasters. Western North Carolina was considered one of the safest regions in the country for weather, yet we were hit by one of the most devastating storms in state history.
Stay prepared. Don’t become complacent.
Thank You!
Over the past few weeks, many of you have reached out with kind words and support, and I can’t thank you enough!
As of this morning, I have 310 messages in my inbox.
I’ve been too busy to reply to emails and comments—though I’ve read each one—but I truly appreciate your patience as I try to catch up. My days have been consumed by helping neighbors and getting our own life back in order. It’s been exhausting but incredibly rewarding, and we still have months of work ahead of us.
Thank you also to the contributors who have kept the SWLing Post running during my absence, and a special shout-out to my friend Vince (VE6LK), who has taken on a huge role in keeping QRPer.com updated.
Thank you so much for your support and understanding—and, again, keep those radios ready. You never know when they’ll become your primary source of information!
Time to upgrade that receiver if you’re one of the few Swiss that still don’t have one able to receive DAB+ signals
Swiss radio listeners will soon have to toss out their old sets, as the country plans to end analog FM broadcasting on December 31, 2024, in favor of a total conversion to digital.
The move has been a long time coming in Switzerland, which has largely already transitioned to Digital Audio Broadcasting (DAB+, an evolution of standard DAB that was designed to address early issues). More than 99 percent of the country have access to a DAB+-compatible receiver and fewer than 10 percent of radio signals in the country still being broadcasted in analog FM, according to the Swiss Broadcasting Corporation.

There will be no substantive changes to the legislation
A bill in the House of Representatives that would mandate AM capability in new vehicles is about to be revised, according to a person familiar with the developments.
New information indicates that one of the original co-sponsors of the bill, Rep. Frank Pallone (D-N.J.), plans to introduce an amendment to the bill (H.R. 8449). Changes would only include minor technical updates.
The planned amendment to the AM Radio for Every Vehicle Act comes on the heels of last week’s last-minute cancellation of a planned vote by the House Energy and Commerce Committee, which could have advanced the legislation to the full House for a vote. [Continue reading…]
Opponents play up the possibility that carmakers would have to choose
If Congress requires AM radio in new cars, vehicle manufacturers might have to drop safety features instead.
That’s the message from opponents of the proposed law in Congress. A guest commentary published by Automotive News restates the key points that opponents have been making since the legislation was introduced; but their blunt emphasis on a possible tradeoff with important safety features seems notable.
“To accommodate analog AM radio as a primary design requirement, certain carmakers may need to scrap advanced safety features, with engineers having to prioritize outdated technology over current or future safety innovations,” they wrote. [Continue reading…]
Did you know that 100 years ago there were electromechanical radio transmitters?
his story has been updated to reflect that the FCC is now seeking public comments on the proposal.
A Mississippi broadcaster is asking the FCC to establish an FM station class called A10, hoping that hundreds of Class A stations would be able to increase power.
He thinks his proposal might stand a better chance at the FCC than the previously proposed Class C4. And on Thursday the FCC announced it will take public comment on the idea. [Continue reading…]
