Stumbled on this rig at an estate sale and laid out a cool $5.00 for her. She was mostly in pieces in a big plastic bag covered in a LOT of dust, and the battery compartment had seen better days. But I thought I could get it going.
Once I got to the chassis I noticed someone with a Golden Screwdriver had been rooting around in there (the PS module was missing screws to the frame and there was some solder bits dancing around inside).
Threw in 4 C cells: pots were noisy, but there was sound, and after liberal application of De-Oxit and some scrubbing the thing snapped to life! Quite good MW reception: I snagged KMOX 1130 St. Louis at 06:30 GMT this morning, a good hop of 960 miles.
Hammarlund only made this Weather/Marine band receiver in 1969-70, so it’s a rare bird, though probably not collectable, per se. Still, it was fun to get the thing operational.
Oh wow! Thanks so much for sharing your flea market find with us, David! I’m so glad you were able to not only give this HR-10 a proper clean-up, but also bring her back to life–and even snag some DX!
Radio Waves: Stories Making Waves in the World of Radio
Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!
Many thanks to SWLing Post contributors Ed, Paul, Bennett Kobb, and Kanwar Sandhu for the following tips:
Here is the story by Bennett Kobb:
As previously reported here at DRMNA.info, the New York company Turms Tech LLC has applied to the FCC for a license for International Broadcast Station WIPE in New Jersey. The license would cover a station already built under a FCC Construction Permit, and would allow it to begin regular operations.
The FCC announced on August 13, 2020 that this license application was accepted for filing, a routine stage at which the FCC examines the application, and might even visit the station, and if everything is in order it will be licensed.
We’re not sure everything is in order. The application for Construction Permit placed the transmitter site at N 40° 57′ 40.38″, W 73° 55′ 23.97″, the broadcast and communications center surrounding the famous Armstrong Tower at Alpine NJ. Its Application for License, however, specifies N 40° 51′ 40″, W 73° 55′ 23″. (Hat tip to Alex P for noting this discrepancy. More about him below.)
While the substitution of 51 for 57 in the coordinates might seem a simple typo, the FCC typically has no sense of humor about coordinate errors. Commission examiners may wonder why a station intended for a historic radio-TV facility ended up among some Manhattan apartments.
The deeper question with WIPE and another, apparently similar station WPBC, is what these stations are really for and what that means for the FCC Rules. WIPE was extremely vague about its program plans, but told the FCC that it will transmit data obtained from third parties using Digital Radio Mondiale. Putting that tidbit together with exposures in a series of public articles in the media and tech blogs, it would seem that audio programming will not be the central mission of this peculiarly named station, whose principal is a financial executive and forestry entrepreneur without any broadcast experience we could find.
We suspect instead that the WIPE data stream will be used not for broadcasting to the public — the only function permitted to International Broadcast Stations under FCC Rules — but instead will be used for private communication with foreign exchanges for high-speed trading.[…]

After bombarding coastal areas of southern Louisiana with wind gusts up to 130 mph and a storm surge over nine feet as a hurricane, Laura swept north while also spreading over Arkansas Thursday. Laura weakened to a tropical storm early Thursday afternoon, with winds at 70 mph, according to the National Hurricane Center. Laura is predicted to move through the Tennessee Valley and the Mid-Atlantic today into tomorrow.
Power outages from the storms totaled over 900,000 as of Thursday afternoon, according to PowerOutageUS. The site collects data from utilities nationwide. The bulk of the outages were in Louisiana and Texas, according to ABC News. Mississippi reportedly had over 9,400 customers without power as of Thursday morning, reported the Clarion Ledger.
Louisiana and Texas had the most cell site outages as of Thursday mid-day, according to the FCC’s Disaster Information Reporting System. Of the 4,650 cell sites served in Louisiana, 380 were not working. Over 200 of the site outages were due to a lack of power, 141 had a transport issue and 16 were damaged.
Calcasieu and Cameron counties were hit especially hard. 140 sites (75 percent) were not working in Calcasieu County and 20 (69 percent) were out in Cameron County.
Of the 17,621 cell sites served in Texas, 113 were non-operational.
Jefferson County was the hardest hit, with 39 (15.8 percent) out of 247 sites not working. Just over 45 of the non-working sites were out due to a lack of power, 41 for transport reasons and 20 were damaged, according to DIRS.
Cable and wireline companies reported 192,915 subscribers out of service in the affected areas; this may include the loss of telephone, television, and/or Internet services.
Three television stations, five FMs and one AM reported they were off-air.[…]
I’ve heard ham radio is dying since as far back as I can remember. It’s one of those common sayings you always hear. Like, “get off my lawn,” and “kids these days.” But is it true? Is there any evidence to support this? Let’s take a closer look.
Data from the ARRL shows that ham radio licensees are increasing. When you look at the chart above, you see two significant markers that are likely driving this growth.
The removal of the code requirement by the FCC.
The economic collapse of 2008.
The Morse code requirement was always an intimidating part of obtaining your General FCC license. Learning Morse code is like learning a second language. It takes time and effort to learn, and that’s not a bad thing. However, it doesn’t change that it scared many people away from the hobby. When the FCC removed this requirement in 2007, I believe it opened the door for many who spent years on the fence. Then you have the economic downturn of 2008. What does that have to do with ham radio? A lot.
After the economic downturn, the United States watched as survivalism, now commonly calling “prepping,” entered mainstream culture. People were worried as the country was involved in multiple wars and our economy was on the brink of collapse. Citizens stocked up on food storage, water, firearms, and…communications equipment. As our country spiraled into more turmoil ham radio licenses steadily increased to more than 750,000 by the end of 2019.[…]
Many thanks to SWLing Post contributor, Andrew, who correctly identified the radio Ed spotted in The Last Man On Earth as the Allocchio Bacchini RF4D. Andrew shared the following notes and links:
That radio is an Allocchio Bacchini RF4D (see photo below from this site):
Here’s a snippet from an Italian movie showing the same rig:
Year : 1940 TX Frequency Range : 1,270 – 4,300 kHz in 3 bands RX Frequency range : 220 – 4,400 kHz in 5 bands Facilities : CW and RT Receiver Circuit (Valves) : Superhet. 7 tubes type 6RV (same as RF 4) Transmitter Circuit (Valves): MO(P C05), PA (2x P CO5) Mod.(3x 6RV) RF Output : 25 W Aerial : Dipole Power supply : 12 V storage batteries. Mains for battery charger.
And here you’ll find the shack of an Italian ham which shows an RF4D:
Wow! Thank you so much, Andrew! I would love someday to operate an original RF4D. What a fascinating WWII era radio. Thank you again for all of the details!
Post readers: I’m very curious if anyone here owns or has owned an RF4D. Please comment!

Benefits to Social Distancing
I have discovered that there is a positive side effect of social distancing. With so many organizations using Zoom and other video methods for their meeting, the volume of great videos to watch has drastically increased, with most of it residing on YouTube. Also everyone is sharing video links that they have found with other.
For example, the New Jersey Antique Radio Club (NJARC) has, for some time, posted their monthly meetings on their YouTube channel. They have very enjoyable presentations. Last night was their virtual monthly meeting for June and they had a great talk by Prof. Joe Jesson on “What You Did Not Know About the RCA AR88.”
I am a fairly new member to NJARC and must recommend them to others. They are a very active group and are currently having Zoom conferences weekly between the members. They also host the RADIO TECHNOLOGY MUSEUM at the InfoAge Technology Center.
Last week, I received an email from Mark Erdle (AE2EA) referring to some videos by the Antique Wireless Museum which is hosted by the Antique Wireless Association (AWA). From his email:
The Radios (and Filming) of “Across the Pacific” presented by AWA member Brian Harrison. Brian served as the radio consultant for the 3-hour PBS documentary “Across the Pacific”, which tells the story of the early days of Pan American Airways and of Hugo C. Leuteritz, a RCA radio engineer who helped make Pan Am’s expansion across the oceans possible with radio communication and navigation systems. Brian explains how he worked to insure that this documentary portrayed the pioneering work of Hugo Leuteritz as accurately as possible. Much of the early radio equipment that Pan American used was custom made for Pan Am, and is quite rare today, but Brian hunted it down.
In addition to Brian’s video, you can also see Tom Perera’s updated presentation of “Phil Weingarten’s Fabulous Fakes” which was originally presented at the 2007 AWA conference:
Here are some other videos that people have passed along to me that I have found enjoyable. Most of these are radio-oriented and I have omitted the many cat videos:
Thank you for sharing these links and videos, Bill! I’ve been watching Phil Weingarten’s Fabulous Fakes this morning–what a fascinating bit of history!
Post readers: Have you discovered videos and sites while social distancing (a.k.a. Social DXing)? Please comment and share your links!
Radio Waves: Stories Making Waves in the World of Radio

Over the last century, radio stations have been the subject and the setting for a number of TV shows and movies. This, for better or worse, is how the general public perceives how real-life radio works. I’ve rated this selection of radio-centric shows and scenes through the years.
1. WKRP in Cincinnati (1978-1982)
Authenticity Rating: 3/5
Every time people of a certain age hear that I work in radio, they inevitably ask “Is it anything like WKRP?” The answer is both yes and no.
The show’s creator, Hugh Wilson, did come from a radio background, serving time as a sales rep at WQXI, a top 40 station in Atlanta, so he was certainly well qualified. His characters were slight caricatures of the real thing: the general manager who was often clueless about what was happening with his station; the harried program director; the burnout morning man; the trippy nighttime DJ; the sleazy salesperson; the squirrely newsman; the naive copywriter; and the receptionist who secretly runs the place. I’ve worked with each of those people multiple times.
The show was groundbreaking in its use of music. Up until WKRP came along, no one used real music in the soundtrack. It was all stock stuff, soundalike material made up by studio players. But viewers of WKRP heard actual songs from bands they recognized — something that eventually created endless licensing headaches when it came to syndication and issuing the show on DVD. That remains the reason why the show isn’t streamed anywhere. (Hugh Wilson explains the music issues here.)[…]
According to a new survey, 76% of Australians oppose any further cuts to the ABC’s budget and 49% believe it should get more Federal Government funding
The findings of a Roy Morgan national opinion poll serve as a warning to the Government that voters have had enough of budget cuts to the national broadcaster. Successive Governments have reduced ABC funding by a total of $783 million since 2014.
The survey shows Australians overwhelmingly turn to the ABC in times of crisis, underlining the national broadcaster’s critical role in the bushfire crisis and the COVID-19 pandemic. ABC Friends commissioned the opinion poll, which was carried out by the independent research group, Roy Morgan.[…]
Fictional novels about number stations have been created in the minds of most people. Many people think of the number station as a ghostly, creepy, mysterious or supernatural symbolic message. But are the messages fictional novel about numbers stations at the number station really mysterious? In today’s discussion we will know what number station is and why somebody finds it fictional novel about number station?
We all listen to the radio more or less. There are basically two types of radio listeners, such as FM radio stations and radio stations broadcast from the Internet. There are also radio stations of other frequencies and their different names. Such as high frequency or shortwave, extra high frequency, ultra high frequency limit through which there is also satellite signal and police scanner report.
Amateur radio, pelagic and air stir are also included in these frequencies. Today we will learn about high frequency i.e. shortwave radio station which is also known as fictional about number station. This number is used to send symbolic messages to various intelligence agencies and the military. This number station has been in found since the First World War and has been the center of attraction for many years. For many years some of journalists have tried to decipher the mystery of this number station.[…]
A teenager who restores and repairs old radios says he loves the “unexplained charm” and history of the wireless.
Diogo Martins, from Oadby, Leicestershire, has been able to spend more time on his hobby during the coronavirus lockdown and has added to his collection of vintage radios.
“Without a doubt many of these radios have a family history where families have gathered around to listen to music and information, and it’s that history which I find so endearing,” he said.
The 19-year-old electrical engineering student said in restoring them he is “continuing their legacy”.
The response from these two posts was pretty overwhelming.
I don’t actually check the SWLing Post viewer stats that often, but I was too curious: together, those two posts amounted to well over 20,000 unique pageviews in two days!
Obviously, I’m not the only radio nostalgic person around here!
These posts resonated so well, I didn’t want readers’ favorite models to be lost in the comments section. I decided to comb through the comments, make a list of all of the models, and link to sites and pages with more information and photos.
This is an interesting collection of radios since some are benchmark performers, while others much less so. Many were listeners’ first radios–the ones we cut our teeth on.
I would encourage you to read through the comments on our first and our second posts. Many great memories in there!
Below, you’ll find the full list of radios in alphabetical order, starting with receivers then moving to transceivers:
Many thanks to everyone who shared their favorite radios! I truly enjoyed checking out each of these models as I listed and linked to them. There were a number of unique models I had never seen before and many I had completely forgotten (like the Sony ICF-SW1000T)!
If you have more favorite models to share, feel free to comment here or on the original posts!
A lot of radios come through SWLing Post HQ each year.
Over the years, I’d like to think that I’ve become immune to the effects of giving away, trading, or selling radios that have been in the shack for a while. But let’s face it: I’m just fooling myself!
I sold both my Hammarlund SP-600 and Hallicrafters SX-99 at the Shelby Hamfest.
As I’ve said before, I find it much easier to part with modern portables, transceivers, and SDRs than I do with vintage gear. With modern gear, I feel like there’s always something new around the corner, thus it’s easy to justify. Plus, I take in so many units on loan for evaluation and review, I see them come in the door and go back out. Occasionally, I like one so much I buy it, but there’s not a lot of attachment. I’m not a “fan boy” of any modern company either, so I don’t intentionally collect rigs.
Ah, but the vints…
I’m a nostalgic guy, so vintage gear comes with more emotional attachment.
Over the years, I’ve had to part with a number of boat anchors because, frankly, I always need a clear space in the shack for evaluating gear and my shack is rather compact. (For example, at one point last year, I had three transceivers here for evaluation all at the same time.)
My Hammarlund SP-600was a very tough one to let go of. I justified it by selling the big girl to my good friend Charlie (W4MEC) who had actually helped me replace some of her capacitors at one point. The SP-600 was simply too deep and too large to fit even on my over-sized radio shelves–especially if mounted in a chassis. Charlie has a much better setup for rack-mounted “heavy metal.” She’s got a good home now.
The Scott Marine Radio Model SLRM
There are two vintage sets I’ll never sell: my Signal Corps BC-348-Q and my Scott Marine SLRM (photo above). How much do I love these radios? My wife has strict instructions to “put’em in the casket with me!”
I did snag this DX-440 last year at the Huntsville Hamfest
No doubt, I miss these radios because they both served me for so many years. We traveled many countries together both on the ground and through the airwaves.
Parting is such sweet sorrow…
A number of readers have confessed that they regretted selling their RF-2200.
Have you ever regretted parting with a radio?Please comment with the model and why it was special to you. I’d also love to hear about the models you currently own and would never consider selling or giving away.
