Zenith Trans Oceanics Still Command Big Prices

by Dan Robinson

For many radio collectors and users, the Zenith Trans Oceanic R7000-2 is a must-have item in the collection. This was the final version of the Zenith Trans Oceanic line that stretched back for decades — production was shifted to Taiwan and tuning in this radio is accomplished with internal gears, with concentric knobs for main and fine tuning.

The R7000-2 has Longwave, AM, FM and importantly for fans of aircraft listening, the radio
has excellent VHF reception. The huge Zenith TO telescopic aerial is a real eye turner — it is
super tall and compares only to the SONY CRF-1 in length.

Some years ago, the used market saw a few NIB or LNIB Zenith R7000-2 every year or so.
That hasn’t been the case — at least it was not until just recently when a LNIB TO appeared from a California seller.

NIB or LNIB R7000-2 radios could often bring more than $1,000 and sometimes much higher —
even as high as $1500!

That did not stop bidding on this-2 R7000-2 from topping the $700 mark and reaching nearly
$800 in this auction.

This does not mean, however, that every R7000-2 will be out of reach but other R7000-2 radios on eBay at this time suffer from cosmetic issues of one kind or another (see photos) such as detached side vinyl and missing antennas.

Amazingly, as this is being written there is yet another R7000-2 on eBay, complete with original
box and papers, and the original purchase receipt. This one could well hit the $1,000 mark.

If you’re hunting for an excellent late production Zenith TO, this may very well be the time
to pull the trigger — but for one in 9.9 to 10.0 NIB condition you will pay a price!

Radio Waves: Potential for Change at USAGM, Judge Rules Pack Unconstitutionally Interfered With VOA, Solar Cycle 25 Could be Strong, and DEF CON Ham Radio Videos

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!

The Biden Choice on USAGM: Business as usual, or major change (USC Center on Public Diplomancy)

Several years ago, I wrote about ongoing problems at Voice of America and its parent agency, which re-branded in 2018 as the U.S. Agency for Global Media (USAGM), and how Donald Trump would deal with them.

I suggested that the Voice of America could be shut down with little impact on the global media scene. This sparked outrage in some quarters, especially from those invested in perpetuating the yearly $600 million to $800 million taxpayer-funded media structure aimed at foreign audiences.

Space limitations prohibit a thorough review of events since Donald Trump’s nominee to head USAGM, Michael Pack, finally achieved Senate confirmation and took up his post after being blocked for two years by Democrats and some anti-Trump Republicans.

Pack faced a wave of hit pieces by major anti-Trump media as he moved to gain control of the bloated and entrenched USAGM bureaucracy, confront security issues at USAGM, and tackle political bias at VOA. His removal of key officials in charge of USAGM networks is still being fought out in the courts.[]

Trump Appointee Unconstitutionally Interfered With VOA, Judge Rules (NPR)

The chief executive over the Voice of America and its sister networks has acted unconstitutionally in investigating what he claimed was a deep-seated bias against President Trump by his own journalists, a federal judge has ruled.

Citing the journalists’ First Amendment protections, U.S. Judge Beryl Howell on Friday evening ordered U.S. Agency for Global Media CEO Michael Pack to stop interfering in the news service’s news coverage and editorial personnel matters. She struck a deep blow at Pack’s authority to continue to force the news agency to cover the president more sympathetically.

Actions by Pack and his aides have likely “violated and continue to violate [journalists’] First Amendment rights because, among other unconstitutional effects, they result in self-censorship and the chilling of First Amendment expression,” Howell wrote in her opinion. “These current and unanticipated harms are sufficient to demonstrate irreparable harm.”[]

Sunspot Cycle 25 could be among the strongest ever (Southgate ARC)

The ARRL reports a research paper has concluded that Solar Cycle 25 will stronger than the just-ended Solar Cycle 24 and likely stronger than Solar Cycle 23

The League says:

A research paper, “Overlapping Magnetic Activity Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude,” by Scott W. McIntosh, Deputy Director of the National Center for Atmospheric Research in Boulder, et al., has concluded that Solar Cycle 25 could be among the strongest sunspot cycles ever observed, and will almost certainly be stronger than the just-ended Solar Cycle 24 (sunspot number of 116). The scientists say it will also most likely be stronger than Solar Cycle 23 (sunspot number of 180). As the abstract explains:

“The sun exhibits a well-observed modulation in the number of spots on its disk over a period of about 11 years. From the dawn of modern observational astronomy, sunspots have presented a challenge to understanding — their quasi-periodic variation in number, first noted 175 years ago, stimulates community-wide interest to this day. A large number of techniques are able to explain the temporal landmarks, (geometric) shape, and amplitude of sunspot ‘cycles;’ however, forecasting these features accurately in advance remains elusive.

“Recent observationally motivated studies have illustrated a relationship between the sun’s 22-year magnetic cycle and the production of the sunspot cycle landmarks and patterns, but not the amplitude of the sunspot cycle. Using (discrete) Hilbert transforms on more than 270 years of (monthly) sunspot numbers, we robustly identify the so-called ‘termination’ events that mark the end of the previous 11-year sunspot cycle, the enhancement/acceleration of the present cycle, and the end of 22-year magnetic activity cycles. Using these, we extract a relationship between the temporal spacing of terminators and the magnitude of sunspot cycles.

“Given this relationship and our prediction of a terminator event in 2020, we deduce that Sunspot Cycle 25 could have a magnitude that rivals the top few since records began. This outcome would be in stark contrast to the community consensus estimate of Sunspot Cycle 25 magnitude.”

Commercial Radio Is 100 Years Old. Can It Survive? (Inside Hook)

Four industry veterans weigh in on how they’d “fix” a medium that remains popular but lacks innovation

The first broadcast from a commercial radio station took place on November 2nd, 1920. Here’s how I imagine listeners responded to the debut of KDKA-AM in Pittsburgh:

Nov. 2: This is amazing! I can hear someone from hundreds of miles away talking through this device! The world will never be the same!

Nov. 3: They’re playing “Wang Wang Blues” again already?

The joke here is twofold: First, there’s a popular song called “Wang Wang Blues” from 1920. And second, by day two, KDKA had already developed the repetitive play-the-hits format that would become one of its hallmarks for the following century.

The first commercial broadcast actually related to the election — it was the idea of a radio manufacturer, Westinghouse, to offer up programming to go along with their newfangled tech (a century later, Apple and Sonos thought exactly the same thing). The first commercial broadcast featured updated results of the Harding-Cox presidential race “before [people] read about it in the newspaper,” as this PBS retrospective notes.

One hundred years later, commercial radio still holds a place in American daily life. The average American still listens to about 106 minutes of radio per day (with the coronavirus and its attendant lockdowns projected to increase that number), and there are more than 15,000 stations in this country alone.

We’re certainly listening to radio differently: according to Statista, 57% of Americans do so online, whether by streaming, downloads, satellite or digital radio. If you asked me how I listen to radio, I’d offer up services like Apple Music 1, Sonos Radio and Dash Radio; podcast downloads from ESPN Radio; online streaming of overseas entities like BBC 1 and Triple J or any occasional college station like WSOU; NPR stations for news and commentary (and music if it’s KCRW); and for new music, a DJ-free experience via Spotify’s New Release Radar playlist. In other words, while audio-only, passive-listening medium has survived and thrived for a century, which is astounding and worthy of celebration, the need for traditional, turn-the-dial “commercial” radio is decidedly on the wane.[]

20th anniversary of first ham radio operation from ISS (Southgate ARC)

On November 13, 2000, the ISS Expedition-1 crew turned on the ARISS Ericsson radio for the first time and completed several contacts with ARISS ground stations around the world to validate the radio communications system

These inaugural contacts launched an incredible two-decade operations journey on ISS, enabling ARISS to inspire, engage and educate our next generation of explorers and provide the ham radio community a platform for lifelong learning and experimentation.

In celebration of the ISS 20th anniversary, ARISS was part of an ISS Research and Development Conference Panel session entitled “20 years of STEM Experiments on the ISS.”  The video below, developed for this panel session, describes our program, celebrates our 20th anniversary, conveys some key lessons learned over the past 20 years and describes the ARISS team’s vision for the future.  Enjoy watching!

20 years of continuous operations is a phenomenal accomplishment.  But what makes it even more extraordinary is that ARISS has achieved this through hundreds of volunteers that are passionate in “paying it forward” to our youth and ham radio community.  On behalf of the ARISS International team, I would like to express our heartfelt thanks to every volunteer that has made ARISS such an amazing success over the past 20 years. Your passion, drive, creativity and spirit made it happen!!

Congratulations ARISS team!!!

Rebroadcasts of RFI programs halt over alleged “pro-China” stance (RTI)

Taiwan’s National Education Radio has decided to stop domestic rebroadcasts of Radio France Internationale’s programs. That’s after receiving listener complaints that the station’s news programs repeated Chinese talking points that praised Beijing, belittled Taiwan, and criticized the US.

National Education Radio had rebroadcast Radio France Internationale’s French and Chinese programs for Taiwanese audiences during two daily time slots under an agreement arranged by RTI.

During a meeting of the Legislature’s culture and education committee Wednesday, KMT lawmakers said that the education ministry should investigate whether the listener complaints were justified or not. They also expressed concern about what pulling the plug of the rebroadcasts might mean for freedom of speech and the press in Taiwan.

During the meeting, Education Minister Pan Wen-chung said that the rebroadcasting agreement had been intended to foster exchanges with France. Pan said the programs originally rebroadcast were mainly focused on educational and cultural topics. However, Pan said that RTI and National Education Radio have decided to temporarily stop the rebroadcasts, since the content of the re-broadcasted programs had begun to deviate from these non-political topics.

Pan said that he had not personally listened to the rebroadcast programs. He also said that the education ministry had not been informed about the decision to halt rebroadcasts until RTI and National Education Radio had already decided to do so among themselves. However, he said that the education ministry supports the decision.[]

New Tecsun PL-368 prototype on display at 2020 Shanghai International High-End Hi-Fi Expo

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following photos and short videos of a prototype Tecsun PL-368 at the 2020 Shanghai International High-End Hi-Fi Expo.

The PL-368 appears to be the updated and upgraded model of the Tecsun PL-360/PL-365 series.

Something I note immediately is the most welcome addition of a numeric keypad for direct frequency entry:

In addition, there’s a “Sync” button indicating the PL-368 will sport synchronous detection, hopefully, with USB/LSB selectable sideband.

Photos

Note, all of the following photos and video were shared by Benny in the Tecsun PL-880 group:

Videos

Dan also shared the following short videos (click links to view):

Many thanks to Benny for sharing these photos and videos from the Expo and thanks to Dan Robinson for sending them to us.

When we learn more about the PL-368, we’ll post details on the SWLing Post. Just follow the tag: PL-368

Sangean ATS-909X2: Production has been “postponed”

Many thanks to a number of SWLing Post readers who’ve noted that Sangean Europe has removed the ATS-909X2 from their website and stopped taking pre-orders.

Dan Robinson received the following response from Sangean Europe after an inquiry:

“The ATS-909X2 is postponed, so we cannot send a product yet. I’m sorry for the inconveniences.”

No doubt, production may be pushed into 2021.
