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

Many thanks to SWLing Post contributors Tracy Wood, Michael Bird, and David Shannon for the following tips:

How accurately have radio stations been portrayed in TV and movies? Alan Cross rates them (Global News)

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.)[…]

Australians overwhelmingly oppose ABC budget cuts (ABC Friends National)

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.

Read the survey here [PDF].

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.[…]

What is number station and story behind it? (US Updates)

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.[…]

Coronavirus: Student repairs vintage radios during lockdown (BBC)

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 Yaesu FT-70G: Where the FT line met Milcom

18 Replies

Earlier today, I stumbled upon a very unique transceiver in Universal Radio archives: the Yaesu FT-70G.

Here’s the description from Universal:

The Yaesu FT-70G is a portable HF transceiver covering 2 to 30 MHz transmit. Receive is from 500 kHz to 30 MHz. Frequency selection is via BCD switches to 100 Hz. There is a clarifier for fine tuning. Optional FNB-70 NiCad Battery. Please note that the optional 10F-2.4DL filter is required for LSB opeation.

The Yaesu FT-70F is similar, but is a channelized fixed version offering up to 11 frequencies.

Two hours ago, I was not aware that the FT-70G existed. Now? I want one!

I’m a real sucker for vintage rugged field radio gear, so I never discovered the FT-70G until today. Turns out, they’re relatively rare. A little light research reveals that it’s a highly-desired transceiver in the world of HF Packers–those radio enthusiast who like “manpack” commercial and military gear.

The FT-70G has a distinct military look and feel with the BCD switches to change frequency, rugged toggle switches, chassis extensions to protect the front panel, and attached screw-on connector caps.

What’s really surprising is that the FT-70G has a general coverage receiver (500 kHz to 30 MHz). Admittedly, it would not be fun band-scanning with those BCD switches…but still!

This website has a number of photos. They also have a product description likely from the original Yaesu/Vertex Standard FT-70G description:

“The FT-70 series HF field portable manpack transceivers are designed to provide reliable communications under rugged conditions in the military and commercial environment. The frequency synthesized, all solid-state circuitry and die-cast anodized aluminum enclosure and battery pack make a highly portable, weatherproof station. Flexible operation for optimum communications under a wide range of propagation conditions are assured by SSB (USB, LSB), semi break-in CW, AM, or audio interfaced Data modes. All controls, antenna, and interface ports are available and selectable via the front panel for maximum effectiveness and ergonomics in field, base, and manpack applications. The companion antenna tuner FC-70 is compatible with walking manpack, field portable, or base configurations. The highly effective vertical tripod mount antenna system YA-70 is deployed and stowed easily and quickly, pulling double duty by converting to manpack whip while on manuevers. High quality handset YH-70 provides communications privacy and clarity.”

Again, check out the excellent photos of the full manpack kit.

As I researched pricing, I discovered this FT-70R with accompanying FC-70M antenna tuner on eBay right now with only 6 hours left of bidding:

At time of posting, the bids are at $520. I fear this will soar well above my comfort level before bidding ends. (Like I need another field radio anyway, right?)

Post readers: Please comment if you’re familiar with the FT-70G and especially if you’ve ever owned one. I’d love to hear about your experience with this unique rig.

Soviet era Kerosene Lamp Generator gives new meaning to “Let’s fire up the radio!”

12 Replies

Many thanks to SWLing Post contributor, David Day, who recently shares the newspaper clipping above.

I was not aware of this Cold War era kerosene lamp generator, but it’s an ingenious use of the thermoelectric effect for power generation. I found yet another another clipping online:

Devices that work off of thermoelectric effect have been around many decades.

The original BioLite stove burns twigs/sticks to recharge USB devices with 3 watts of power.

I’ve often thought about purchasing a BioLite camp stove–the same one Anil Raj mentioned in our Radio Challenge II–as a companion to charge devices while camping off-grid.

BioLite now makes a more efficient (albeit pricier) stove that produces more power with less fuel.

At the end of the day, I find it so easy to use solar power to recharge larger LiFePo batteries, I’ve never invested in the BioLite.

With one large LiFePo battery, I’m able to power multiple devices including an inverter if necessary.

I’m very curious how many models of kerosene lamp generators were made back in the day and how useful they were for powering other low-drain devices.

Please comment if you’ve ever used a kerosene generator. We have readers from across the globe, so I imagine someone may have at least seen one of these in person and potentially used it to power a radio!

Oh, and obviously I need to think up another SWLing Post Radio Challenge–it’s been ages since our last!

Let’s take a deep dive into a list of our favorite radios!

16 Replies

Over the past week, I asked the SWLing Post community if they’ve ever regretting parting with a radio, and then what radios they’ve owned that had the most “fun” factor.

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:

Radio Waves: ABC Wage Freeze, A Titanic Radio, FCC “Tweaks” LPFM Rules, and Digitizing a DX-160 Display

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Michael Bird, Dave Zantow, David Korchin, and Alokesh Gupta for the following tips:

ABC must freeze wages, government warns (The Guardian)

The Morrison government has put the national broadcaster on notice that it expects the ABC to embark on a six-month wage freeze to bring it in line with other taxpayer-funded agencies during the Covid-19 crisis.

The warning follows the government’s decision in early April to defer general wage increases for commonwealth public servants for six months. The public service commissioner followed up that directive by writing to all non-public service agencies – including the ABC – informing them the government expected them to adopt the same practice.

With no clear response from the ABC to the 9 April missive, Guardian Australia understands the communications minister Paul Fletcher wrote to the national broadcaster this week flagging his expectation that the organisation would defer a 2% increase for all employees scheduled to take effect in October under the ABC’s enterprise agreement.[…]

Radio used by the Titanic to call for help can be salvaged, judge rules (CNN)

A federal judge has ruled that RMS Titanic Inc. can salvage the radio used to call for help by the fated ocean liner after it struck an iceberg in 1912.

To get to the radio, divers would need to remove a part of the ship’s deckhand to reach the room known as the Marconi Suite, which houses the device.

The ruling modified an order issued on July 28, 2000, that said that RMS Titanic Inc. could not cut into the wreckage or detach any part of it.

Virginia’s eastern district court amended that order “for a unique opportunity to recover an artifact that will contribute to the legacy left by the indelible loss of the Titanic, those who survived and those who gave their lives in the sinking,” Judge Rebecca Beach Smith wrote.

Experts in the case testified to the “significant deterioration” in areas above and around the Marconi room, according to the document, and photos showed the “increasing breakdown” in the deck above the suite.

The suite, made of steel, consisted of three areas: sleeping accommodations, an operator’s room and the silent room that housed the radio. Each area was separated by wood walls that officials believe have dissolved, according to court documents.

The Marconi device and the artifacts associated with it face “significant threat of permanent loss,” the judge said in her approval of the expedition.[…]

FCC Tweaks LPFM Technical Rules (Radio World)

The FCC in April modified the technical rules covering low-power FM stations. It expanded the permissible use of directional antennas; permitted waivers of protections of television Channel 6 by a specific group of reserved channel stations; expanded the definition of minor change applications for LPFM stations; and allowed LPFM stations to own boosters. Read more about the changes here.

Michelle Bradley, founder of REC Networks, is an engineer and longtime LPFM advocate.

Radio World: What’s your overall assessment of the outcome and the scope of its impact in the LPFM community?

Michelle Bradley: While the FCC did not address three major issues that are impacting LPFM stations right now —the ability to address building penetration issues, the ability to reach “local” listeners in rural areas and the disparity in how LPFM stations protect FM translators vs. how translators protect LPFMs — the changes will benefit current LPFM stations by giving them more flexibility in moving locations, reduce the need for waivers and improve LPFM service in the southern border region. It will also open some additional opportunities for new LPFM stations in the next filing window.[…]

RadioShack Shortwave Goes Digital (Hackaday)

If you spent the 1970s obsessively browsing through the Radio Shack catalog, you probably remember the DX-160 shortwave receiver. You might have even had one. The radio looked suspiciously like the less expensive Eico of the same era, but it had that amazing-looking bandspread dial, instead of the Eico’s uncalibrated single turn knob number 1 to 10. Finding an exact frequency was an artful process of using both knobs, but [Frank] decided to refit his with a digital frequency display.

Even if you don’t have a DX-160, the techniques [Frank] uses are pretty applicable to old receivers like this. In this case, the radio is a single conversion superhet with a variable frequency oscillator (VFO), so you need only read that frequency and then add or subtract the IF before display. If you can find a place to tap the VFO without perturbing it too much, you should be able to pull the same stunt.

In this receiver’s heyday, this would have been a formidable project. Today, a cheap digital display will do fine.[…]

Have you ever regretted saying goodbye to a radio?

40 Replies

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!”

There are only two portable radios I regret selling: my original RadioShack DX-440 and my Grundig YB400.

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.

Dean’s love of the JRC NRD-515 spans 35 years…

17 Replies

Many thanks to SWLing Post contributor, Dean Bianco, who kindly allowed me to share his note which accompanies the photo above:

Me and my then brand-new JRC-NRD-515 in 1985.

Thirty-five years later in 2020, it is still with me. It works today as it did when it was first taken out of its box! This fact is a testament to the 515’s precision engineering, high-quality components, and tank tough build! The only trouble in these 35 years was the gummy 2.4 kHz mechanical filter issue that all 515’s eventually suffer. However, that was an easy fix and other than de-oxit every five years in the controls, and dusting the interconnect circuit wire RCA plugs, it performs flawlessly. It was used two hours ago.

I have an advanced SDR stand-alone, the astounding Icom R-8600 that has better sound, better specs, and more facilities to peak and tweak a flea-powered signal out of a huge pile of powerhouse flamethrowers than does the old 515. But, when I want to experience the old-school large knobs, the large tuning wheel and the sheer enjoyment that only an old heavy metal radio can provide, I turn to the classic NRD-515!

I don’t blame you, Dean. I have never owned an NRD-515, but I have always admired its design and layout. It has such an all-business, military/rugged look. One thing I really love about the NRD-515 is how the RF and AF gain pots flank either side of the main encoder. The controls spacing is also ideal, in my book. Check out the following photo I took of Dan Robinson’s NRD-515:
