Indy 500 Week Marks the Second W9IMS Special Event of 2021

Indy 500 Week Marks the Second W9IMS Special Event of 2021

By Brian D. Smith, W9IND

If you’re looking to add a 2021 Indy 500 QSL card to your collection, and perhaps a certificate as well, your odds of success just accelerated. From now through the end of Sunday, May 30 (Race Day), the Indianapolis Motor Speedway Amateur Radio Club will take to the airwaves with special event station W9IMS.

The station’s SSB signals will appear daily on 20 and 40 meters – usually on or around 7.245 and 14.245 MHz – and possibly on 80 meters (near 3.840 MHz) later in the evening.

The Indy 500 special event is the second of three W9IMS operations commemorating the major races at the Speedway – and comes only 9 days after the first, which honored the IndyCar Grand Prix. The third and final special event of 2021, which runs from Aug. 9-15, celebrates the NASCAR 400 at the Brickyard.

Both hams and SWLs are eligible for the newly designed 2021 W9IMS QSL cards and Checkered Flag Award. To earn the certificate, however, you must work (or tune in) W9IMS during all three of this year’s special events – and the first race has already come and gone. But even if you miss the clean sweep, you can still claim individual QSL cards from the last two races.

Tips on finding W9IMS:

  1. Check DX Summit (www.dxsummit.fi) for spots listing the current frequency or frequencies of W9IMS, if any. By typing “W9IMS” in the search box at upper right, you can customize it to show reports for only that station.
  2. Go to the W9IMS web page (www.w9ims.org) and look for the heading, “2021 Operating Schedule.” Click on the Indianapolis 500 link, which opens into a weeklong schedule listing individual operators and their reserved timeslots. Your odds of catching W9IMS on the air are enhanced during hours with an operator’s name attached.
  3. Prime time on weeknights is 6 to 10 p.m. Indy time (2200-0200 UTC). However, W9IMS can pop up anytime, even on two bands at once, between now and 11:59 p.m. Sunday, May 30 (0359 UTC Monday, May 31).
  4. Remember that the published schedule can be curtailed by adverse circumstances, such as noisy bands, local thunderstorms or a lack of calling stations.
  5. On the positive side, operators frequently fire up the station at unscheduled times. That’s why DX Summit is the best starting point for locating W9IMS’s current frequencies.

Armin hears “clicks” after update of SI473x receiver firmware

Many thanks to SWLing Post contributor, Armin Sander, who writes:

Hello Thomas,

Thanks for posting the info on the SI47xx firmware-update.

I have done the update and the receiver runs now on firmware ver. 3.0.7a

It works fine but I hear now on am/lw/shortwave “click” noises on the radio.

Is this the sign that something is wrong with the firmware programming?

Before I had the ver. 1.5 on my radio without these noises.

Maybe you can post this info on your homepage.

Best Regards from Germany

Armin Sander

Thank you for the feedback, Armin. My hope is that an SWLing Post reader might be able to help you hear. I haven’t heard others report of click noises yet.

UNID Russian Numbers Station recorded April 26, 2021

Many thanks to SWLing Post contributor, Paul Walker, who recently shared this recording of an unidentified numbers station in Russian.

Paul recorded this on April 26, 2021 at 0218 UTC in McGrath, Alaska, on 11,615 kHz:

I’m not an expert on numbers station identification–if you can ID this station, please comment!

Update: Many thanks to a number of readers who have suggested that this is the “S06 Russian Man” station.

SI473x Receiver Firmware Update and Internal Photos

Many thanks to SWLing Post contributor, Robert Richmond, who writes:

Hi Tom,

Ricardo (PC2CLR) recently published an excellent firmware update for the SI473x kit-based receivers flooding AliExpress, eBay, etc.

I purchased a preassembled SI473x model, and it has a much better user interface following the update IMO. Other changes include being able to tweak or disable soft mute, finer grained attenuation, and a few options being moved to the encoder instead of multiple button presses.

The update including directions and a list of features can be found here:

Robert also kindly shared the following internal photos of the SI473x receiver:

Robert, thank you so much for sharing the information and your SI473x photos/mods!

John’s 1965 RCI Shortwave Club certificate triggers serious shortwave nostalgia!

Many thanks to SWLing Post contributor, John (G3VUO), who shares the following:

Hi Tomas,

Seeing [the] article about RCI prompted me to remember the halcyon days of SW Listening.

I still have my RCI Shortwave Club certificate issued in 1965 when I was only 14 years old!

In those days you had to monitor their broadcasts regularly and send listening reports on (if I remember correctly) green airmail reception forms every month.

Hope the attached may give other readers some memories.

Wow! Thank you for sharing this, John. Those were, indeed, the halcyon days of shortwave radio listening!

Post readers: Please comment if you’ve also received a certificate from RCI!

Radio Songs by Silvia Swart

Many thanks to SWLing Post contributor, Bill Hemphill, who writes:


I ran across a reference to Radio Delta International Shortwave, a Hollands station on 6020 kHz.  The reference was to a song that was recorded for them by Silvia Swart en het Radio Delta lied.  Which (according to Google) translates to The Radio Delta Song.  It’s on YouTube and I like the sound of it even thought I don’t know Dutch.

YouTube link to the Radio Delta song:

There’s some nice photos and background to the station equipment on Delta Radio web site;

https://radiodelta.am/

After listening to the song by Silvia Swart, I did a search on her and found that she did other radio songs.

Radio Krachttoer:

Radio Combination Team:

Hopparadiotune:

Radio Waubach:

Hinnehok fm lied:

Supervision Radio:

Next step was to dive in and learn a little more about her.  Thank goodness for Google Translate.  From her website

https://www.silviaswart.nl/

I learned that Silvia has made over 155 tunes for legal / illegal pirate stations, associations.

Her parents run a record shop in Holland and that her father, Record King JB Swart, produced the Original Pirate Hits.  From his web site

https://www.jbswart.nl/

I learned that his store carries Pirate Music as well as the usual Dutch and other stuff a record store would normally carry.  Now I understand her interest in radio.

One last song I found that she recorded with her group, The Greenlights:

Mijn opa is een zendpiraat

Which translate to: My grandfather is a radio pirate

Maybe one of the forum members can give us a quick translation/summary of the songs.

NHK World celebrates 80 years of radio service

Radio service for overseas marks 80 years.

A ceremony has been held to mark 80 years since the start of radio service at Japan’s only station broadcasting programs overseas on shortwave bands.

The KDDI Yamata Transmitting Station in Koga City in Ibaraki Prefecture, north of Tokyo, is used by NHK World Radio Japan.

About 50 officials from NHK, KDDI and other entities took part in the ceremony on Wednesday.

The chief of the communications ministry’s Kanto Bureau of Telecommunications, Tsubaki Yasufumi, said remotely at the event that he honors the station’s 80 years of stable operations. He also said he hopes for continued efforts so that programs from Japan can be broadcast overseas.

Terada Kenji of the NHK Engineering Administration Department said shortwave broadcasting served as a lifeline on many occasions such as the 2014 coup in Thailand. He said he wants to express gratitude to all the people involved in shortwave broadcasting.

After the ceremony, the head of the station, Saito Toshimitsu, said it plays an important role in providing information from Japan. He added that he will keep working hard so that the station will be passed down to younger generations.
