Pentti Stenman’s impressive collection of SWL recordings, QSLs, and pennants

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

Just ran across this guy’s site Pentti Stenman, who is in Finland.
Check out his audio and QLS, pennants as well…

Pentti’s collection is impressive indeed! Since he’s in Finland, some of his site is in Finnish, but it’s still quite easy to navigate and you can have Google translate it into any language.

I have pasted direct links below to Pentti’s various galleries.

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 Troy Riedel, Dennis Dura, and Dan Robinson for the following tips:


Ernest Eugene “Gene” Pell 1937-2020 (Radio Free Europe)

As noted in this obituary published by his hometown newspaper, The Paducah Sun, Ernest Eugene “Gene” Pell, 83, died quietly on April 7, 2020, at his home near Syria, after a 3-year battle with cancer. Pell served as President and Chief Executive Officer of Radio Free Europe/Radio Liberty (RFE/RL) from 1985-1993, leading the Radios during the peaceful revolutions that occurred in Eastern Europe and the Soviet Union from 1989-1992.

In Tribute to Gene Pell

In 1989, we who were privileged to serve in the management of RFE/RL as Gene Pell’s colleagues watched the awesome professionalism of RFE/RL’s broadcasters as peaceful revolution swept from the Baltics to the Balkans, and the Radios helped each country share with others the power – even the slogans – of peaceful protest, and the wisdom of restraint by police and armed forces.

Romania was a tragic exception. Ceaucescu’s regime was doomed by RFE’s broadcast of a recording of the shooting of civilians protesting in Timisoara. As Ceaucescu fled Bucharest, and violence by unknown combatants erupted, Gene ordered a million watts of shortwave power from our transmitter stations across Europe diverted to the Romanian service. Before long, Romanian army commanders seeking to restore calm established phone contact with the service in Munich.

In the immediate aftermath of the liberation of Eastern Europe, and the 1991 collapse of the Soviet Union, Gene saw the need and found the resources to open bureaus across the region and begin on-the-ground reporting by talented local journalists – and local rebroadcasting of RFE/RL programming.

And he persuaded the U.S. government to allow RFE/RL for the first time to broadcast to the former Yugoslavia, during the Bosnian War, with a new, multi-ethnic service led by Nenad Pejic*.

On Gene’s watch, Lennart Meri, Foreign Minister of a newly free Estonia, nominated RFE/RL for the Nobel Peace Prize.

Gene’s leadership was crucial as another struggle soon ensued, this time in Washington, as efforts arose to save the federal government money by shrinking or closing the Radios, on the premise that if Europe was free, why did we need Radio Free Europe (and Liberty)? Support from new democratic leaders across the region, notably from Lech Walesa and Vaclav Havel, helped convince a Presidential Commission addressing this question that the Radios’ mission should not end but evolve, as it has.

The views of these freedom leaders were decisive in keeping RFE/RL on the air and positioned to win the enormous multi-media audience it enjoys today. Gene Pell’s vision is alive for future generations.

Two of my closest colleagues, Ross Johnson and Kevin Klose, join me, as I am sure many others would, in saluting Gene for his contribution to a freer world.

A Dangerous Demonstration of the Power of Radio (Hackaday)

Terrestrial radio may be a dying medium, but there are still plenty of listeners out there. What would a commute to or from work be without a check of “Traffic on the Eights” to see if you need to alter your route, or an update of the scores from yesterday’s games? Getting that signal out to as many listeners as possible takes a lot of power, and this dangerous yet fascinating demo shows just how much power there is on some radio towers.[]

White House Criticism of VOA, Unprecedented in its 78 year History (Public Diplomacy Council)

The Voice of America is the nation’s largest publicly-funded international broadcaster, reaching 280,000,000 multimedia users in 47 languages each week, many of whom access it daily for honest, balanced and accurate world news.

To most senior VOA officials, past and present, including this writer, an unsigned White House blog on April 9, 1600 Daily, omitted or misstated vital information about the scale and original date of the coronavirus outbreak in mainland China. That blog asserts in a bold headline: “Voice of America spends your money to speak for authoritarian regimes.”

But that attack was just the beginning.

President Trump went even further at his daily news briefing on April 15, largely devoted to the coronavirus. “If you heard what’s coming out of the Voice of America, it’s disgusting”. The President then assailed Congress for failing to take up his nomination of conservative Michael Pack as chief executive of all five U.S. funded multimedia organizations, the U.S.Agency for Global Media, until recently known as the U.S. Broadcasting Board of Governors.

The USAGM is the oversight body of five overseas multimedia U.S.-funded networks: VOA, Radio Free Europe/Radio Liberty, Radio Free Asia, the Middle East Broadcasting Network in Arabic, and Radio/TV Marti in Spanish to Cuba. Research in approximately 100 countries indicates that collectively, the five networks reach 350,000,000 people abroad every week.[]

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!

The LAN-IQ can be connected to a PC via USB or Ethernet (at a 2400 kHz sample rate).

The Afedri website also has a few videos of the LAN-IQ in operation:

As you might have noted, the encoder knob seen in Fenu’s video is not standard but can be added at an additional cost and extended lead time. If I were to order the LAN-IQ, I would want the encoder knob as well.

Also, note that due to Covid-19 affecting the supply chain, Afedri SDR informs me that LAN-IQ availability will be adversely affected. If you would like to order a LAN-IQ, contact Afedri SDR via their website.

Tecsun PL-990: How to distinguish pilot run and final export versions

The Tecsun PL-990

As I suspected, it appears the Tecsun PL-990 batch that showed up recently on AliExpress for $399 each are the preliminary pilot run units that Tecsun offered in China last year. The final export version of the PL-990 is not ready for production yet and has been severely delayed by Covid-19 quarantines.

Anna at Anon-Co reports that Tecsun factories have been closed since mid-January 2020 and have only recently recommenced production, “but at a very slow pace.”

Since there will eventually be two different versions of the Tecsun PL-990 in the wild–the pilot run for China, and the finalized export version–I thought I’d share a trick Anna has described to tell the difference between the two.

Anna notes:

One way to easily see this is from the labels for the buttons above the keypad, these should be

[ TIME ], [ TIMER A ], and [ TIMER B ] (see picture below)

Tecsun PL-990 Final Export Version:

Tecsun PL-990 Final Export Version

Pilot Tecsun PL-990 (preliminary China domestic version):

Anna adds:

I highly recommend [no one] buy these pilot versions, because the software on those devices is also not developed.

There still isn’t a final version or any price indication available yet, but it will definitely not be US$399.99.

So in case it’s not clear: don’t purchase a PL-990 until you can confirm you’re receiving a final export version which has the TIME, TIMER A, and TIMER B labels.

Again, at time of posting, the final PL-990 export version is not yet in production.

When the final export PL-990 is available, I will announce it here on the SWLing Post with links to authorized retailers like Anon-Co.

Tecsun PL-990 (pilot run) now on AliExpress

Many thanks to SWLing Post contributor, Dan Robinson, who notes that the Tecsun PL-990 has now appeared on AliExpress.com.

The price is a steep $399 US shipped via DHL with an estimated delivery of late March. They claim to have about 900 units available.

You can check out the PL-990 on the AliExpress website, but it might require registration even via this direct link.

Frankly, I would wait until the PL-990 is available at Anon-Co since they’re an authorized Tecsun distributor, have proven customer service, and will likely have a more competitive price. I would also question if the AliExpress units are the new export version we’ve been waiting for, or simply the units that were available within China last year. The AliExpress page gives us no clear indication of the production version at time of posting.

UPDATE: Turns out, these are the pilot Chinese versions of the PL-990. I can’t recommend purchasing one–especially at this price.

I hope this might indicate that the PL-990 is close to release. Covid-19 has certainly stopped much production and development in China. Thanks again for the tip, Dan!
