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

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:

Thanks so much, Dean!

Any other NRD-515 owners or lovers out there?  Please comment!

Ted inherits two vintage receivers and a 1959 UK Receiving License

Many thanks to SWLing Post contributor, Ted Lampert, who writes:

I was given some old radios belonging to a family member who passed a few years back.

A couple of them really sweet, a Philco 46-420, and a Philips B3X82U (see photo above).

Included was an envelope with some papers in it. One was the instruction booklet for the Phillips B3X82U, in multiple languages:

Another was a receiving license.

Without outing him too much, the original owner did government work and was stationed overseas quite a bit. The license looks like it was good for 1960, and I’m guessing you went to the post office to get it. It references the wireless telegraphy laws 1952 & 1955. Have you seen one of these before and do you know much about these receiving licenses?

The Philips is the radio I believe would have been probably what he got this license for since it says Philips at the top of it.

[…]Anyway, going through stuff recently, saw the license and started wondering about it.

Keep up the good work, seeing almost daily new articles on your site played a big part in keeping me inspired to get my own license, not a receiving one, but an amateur. Got general on the first try back in the fall of last year!

First of all, congratulations on snagging your General license last year!  Well done!

Both the Philips and Philco are gorgeous receivers! What treasures! Ted, you had mentioned elsewhere in your message that you plan to recap them and I’m very pleased to hear this.

Like you, I was not aware of that receiving licenses were issued in the UK at the time. Perhaps this was implemented during or after WWII and was simply a requirement during the Cold War?

My hope is that a knowledgeable SWLing Post reader can shed some light on the Receiving License. Please comment with details!

Mystery Radio: Can you help Ray ID this solid-state radio from the film “Ford v Ferrari”–?

Many thanks to SWLing Post contributor, Ray Robinson, who writes:

Hi, Thomas. In the 2019 movie Ford v. Ferrari, a battered old shortwave radio is used in California to listen to commentary on the 1966 Le Mans race from France.

I’ve attached a few stills from the movie (which I highly recommend, by the way). Might any of your subscribers know the model of the radio?

Post Readers: Please comment with links if you can ID the make and model of this radio. It looks very familiar, but then again the design is similar to so many other models of the era. Ray, I look forward to checking out the film, too!

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 Kim Elliott, Dave Anderson, and Paul Evans for the following tips:


“Infotainment Systems” In Cars Portend Safety, Privacy, And Competition Issues (Forbes)

Almost all new cars include so-called “infotainment systems,” which provide navigation and various sources for music and news. Most companies have begun to outsource these systems to the Silicon Valley mainstays such as Apple, Amazon, and Google. The electric car manufacturer Tesla, however, has developed its own infotainment system that is far more integrated with the car itself.

Tesla recently announced an “upgrade,” which would allow users to watch Netflix, Hulu, and YouTube (when the car is parked). This innovation has a flip side: it removes AM / FM radio capabilities. Tesla and other electric car manufacturers claim they have removed AM radio in many of their models due to concerns over interference. But Tesla’s announcement is peculiar because electric engines do not interfere with FM radio reception.

Former FEMA director Brock Long worries that Tesla’s decision could prevent the government from transmitting crucial information in emergencies. Long’s concerns are valid, particularly in a crisis like the ongoing pandemic, when broad communication with the public is necessary to protect national security. AM/FM radio reach places that television and broadband do not, and that is why the government has invested tens of millions of dollars to ensure radio stations can remain on the air during periods of widespread threat to the public – including the current one. As the coronavirus reminds us, our nation still has public safety needs that no amount of technical wizardry can obviate.

The public safety concerns are real, but Tesla decision to remove AM/FM radio also raise the perennial tech issues of privacy and competition.

Tesla has contracts with tech companies such as Spotify and Pandora, many of which are pay services. These tech companies are no doubt pleased that Tesla is contemplating taking out AM/FM radio, which is still the most listened to audio platform—and constitutes meaningful competition. However, these conflicting interests creates mismatched incentives for Tesla.

Because Tesla’s market share is small, and the upgrade is optional, this conduct likely does not rise to anything close to an antitrust violation. However, the vertically integrated model which Tesla is following raises the same type of concerns as when Big Tech firms pick and choose what apps and services customers can favor. If Google, Apple, and Amazon, which have their own podcast and streaming audio services, begin to demand that auto manufacturers carry their services exclusively, then more serious competition problems will arise.[]

Odd Crosley Radios from the 1920s (Hackaday)

You may sometimes see the Crosley name today on cheap record players, but from what we can tell that company isn’t connected with the Crosley Radio company that was a powerhouse in the field from 1921 to 1956. [Uniservo] looks at two of the very early entries from Crosley: the model VIII and the XJ. You can see the video of both radios, below.

The company started by making car parts but grew rapidly and entered the radio business very successfully in 1921. We can only imagine what a non-technical person thought of these radios with all the knobs and switches, for some it must have been very intimidating.

The model VIII had two large knobs, three small knobs, and a switch. Oddly enough there were very few markings on the knobs, as you were expected to know how to use a tuned RF radio. The large knobs were for tuning capacitors and the switch was for coil taps, while the three small knobs controlled the tube filament supplies.[]

Panasonic RF-2200 antenna coupler (model RD-9820) on eBay

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who recently discovered a model RD-9820 antenna coupler for the Panasonic RF-2200. Mario states, “[The] price is reasonable and they take offers.”

Please, someone purchase this before I do in a moment of weakness. I’ve two RF-2200s, but do not have the matching coupler. It is incredibly temping even though I know I’d rarely use it!

Video: Antonio’s Kenwood R-2000 Modifications

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following:

Antonio Fernandez, who is in Spain, posted this on the Extreme page. Very interesting R-2000 mods:

Major modifications are adjustable RF GAIN (using the former TONE control), BFO Pitch control (former AM Squelch, FM Squelch is retained) and DSP Audio filtering for SSB and CW. Internal DSP module is SOTABEAMS Laserbeam Filter Module. The former DIMMER and NB push switches are used for switching on (bypassing) the DSP module and bandwidth (CW, SSB) selection.

Those are brilliant modifications on a classic receiver!  Thank you for sharing, Dan!
