Visiting the Kon-Tiki Museum: The NC-173 Lives On

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

Hi Tom – some years ago, you posted an article about the famous Kon-Tiki expedition and the use of the National NC-173 on board.

Well, today during my first-ever visit to Oslo, Norway, I stopped by the Kon-Tikki museum – devoted to the r expeditions of Thor Heyerdahl.

And sure enough, right there in the Kon-Tikki raft exhibit you can see the actual radio he used! In fact, the radio operator was a radio operator named Knut Haugland, who was also a radio operator for the Norwegian resistance during World War II. There is a photo in the museum of him operating the NC-173, which I am also including here.

If you are ever in Oslo, the museum is definitely worth a visit!

All the best,

Robert

August 2026 Schedule Updates: From the Isle of Music & Uncle Bill’s Melting Pot

The Sound of Soft Power: Airing on BBC World Service, August 1–2, 2026

2 Replies

The BBC World Service will rebroadcast The Sound of Soft Power—the excellent radio documentary exploring the enduring influence of international broadcasting and shortwave radio—via its shortwave service on the following dates:

First transmission: 18:00 GMT, Saturday, 1 August 2026
Final transmission: 11:00 GMT, Sunday, 2 August 2026

I’ll post the frequencies as soon as I’m notified, although I expect they’ll follow the BBC World Service’s normal shortwave transmission schedule.

I’d love to add a good off-air recording of this broadcast to the Shortwave Radio Audio Archive. I’ll certainly try to make a recording myself, but I may not be in the best location for reception. If you’re able to capture the broadcast, please consider sharing your recording!

If you missed my original post about The Sound of Soft Power when it first aired on BBC Radio 4 in May, you can read it here: BBC Radio 4 explores shortwave broadcasting and soft power (May 2026)

The W9IMS Brickyard 400 Special Event: Third Time’s a Certificate

Leave a reply

By Brian D. Smith, W9IND

Trifectas aren’t usually associated with auto racing, but this week’s run-up to the NASCAR Brickyard 400 will find thousands of amateur radio operators and SWLs pursuing just that: contact with the third and final Indianapolis Motor Speedway special event station of 2026.

In their quest for a colorful certificate, the Checkered Flag Award, radio enthusiasts who already worked or tuned in W9IMS during the previous two special events in May are now aiming for the clean sweep. The station will be on the air at various times from now till 11:59 p.m. on Race Day Sunday, July 26 (Indy time)/0359 UTC Monday, July 27.

But even if you missed out on either or both of the first two special events, which honored the IndyCar Grand Prix and the Indianapolis 500, there’s still time to claim a collectible bounty. The Indianapolis Motor Speedway Amateur Radio Club, the events’ organizer, offers an all-new commemorative QSL card for each race.

So how to win the paper chase?

W9IMS operates almost exclusively on 20 and 40 meters, with preferred frequencies of 14.245 and 7.245 SSB. But QRM can send the station far from those usual hangouts.

Here are a few tips on locating W9IMS:

1. Go to the W9IMS web page (www.w9ims.org) and look for the heading, “2026 Operating Schedule.” Click on the “Brickyard 400” link, which opens into a weeklong schedule of individual operators and their reserved time slots. Although participants frequently get on the air at unscheduled times, your odds of catching the station improve significantly during hours with a listed op.

2. Even if no operator is scheduled, check DX Summit (www.dxsummit.fi) for spots listing the current frequency or frequencies of W9IMS. You can customize your search by typing “W9IMS” in the box at upper right.

3. Your best chance for finding W9IMS active on weeknights is during the station’s prime time: 6 to 10 p.m. in Indy (2200-0200 UTC). However, operators may show up an hour or two early or continue till 11 p.m. and even past midnight if band conditions allow. It can also be fruitful to check DX Summit during mornings and early afternoons.

4. Remember that the published schedule can be shortened by adverse circumstances such as local thunderstorms, a lack of calling stations, and solar anomalies. Don’t wait till the last hour to hunt W9IMS.

5. Even so, if you still haven’t worked W9IMS by the final weekend, don’t give up too soon. Toward the end of the operation, ops often call for “only stations that haven’t worked us this week” and/or switch to a contest-style format, exchanging just signal reports to give more paper chasers a chance.

6. Keep in mind that both hams and SWLs are eligible for QSL cards and the certificate. So if you’ve made two QSOs and haven’t completed the trifecta by Sunday evening, you can use an SWL report for your third credit. Just copy down the basic details – such as the time (UTC), date, frequency and the callsigns of three stations you heard W9IMS working. The certificate may feature your name instead of your call, but should otherwise be indistinguishable from a standard-issue Checkered Flag Award.

7. Still have questions? Email [email protected] for the answers.

There’s something curious about listening to this tiny Sony SRF-SR84 receiver: when I hold it close to this metal fence, the medium wave reception improves significantly.

Many thanks to SWLing Post contributor and noted political cartoonist Carlos Latuff, who shares the following illustrated radio listening report.
