Court of Dreams: How shortwave radio lead to a lifelong obsession with tennis

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following video from CBS Sunday Morning and notes:

For those who may have missed this recent CBS Sunday Morning piece, which tells the story of a guy who, inspired by BBC broadcasts of Wimbledon, built his own top-level court in Iowa. It’s not often that shortwave gets such national exposure:

(Via CBS Sunday Morning on YouTube)

“If you build it, they will come.” In the case of one tennis-obsessed fan who built a replica of Wimbledon’s center court on his Iowa farm, people have come from around the world to his All-Iowa Lawn Tennis Club, to play on his court of dreams. Steve Hartman reports.

This absolutely made my day, Dan!  Thank you for sharing.

Video: TX Factor Episode 17

(Source: TX Factor)

TX Factor goes digital as Mike Marsh gives Bob McCreadie an introduction to operating on DMR, Yaesu Fusion and D Star as part of his digital fun. In part one of a three-part series, they take a trip to a local farm to see how an amateur has set up his own Fusion Gateway.

Ever wonder why QSL cards take a long time to complete their journey? Bob finds out what we can do to help speed up he process.

Pete visits Norwich to spend a day with the Norfolk Amateur Radio Club at their annual field day event, Radio Active to discover why they won the coveted prize of RSGB Large Club of The Year.

This is another excellent TX Factor episode well worth your time. I was especially impressed with the in-depth feature about the Norfolk Amateur Radio Club–truly a case study for other amateur radio clubs who struggle with outreach.

Listening across the globe: The 2017 BBC Antarctic Midwinter Broadcast

Halley VI: The British Antarctic Survey’s new base (Source: British Antarctic Survey)

On Wednesday, 21 June 2017, the BBC World Service officially transmitted the 2017 BBC Antarctic Midwinter Broadcast–an international radio broadcast intended for a small group of scientists, technicians, and support staff who work for the British Antarctic Survey.

This is one of my favorite annual broadcasts, and I endeavor to listen every year. Once again, the SWLing Post called upon readers to make a short recording of the broadcast from their locale.

Below are the entries, roughly organized by continent and country/region, including reader’s photos if provided. If I’ve somehow missed including your entry, please contact me; I’ll amend this post.

So, without further ado….

I was curious to listen this transmission and Wednesday I tried to receive it with a little Tecsun PL-300wt and its antenna.

SWL: Ayrshire, Scotland
Location: Scotland
Notes:
Tonight I rushed home from work in time to hear the broadcast. Signals were good at my QTH in Scotland, even though we had thunder storms to the East of Scotland.

I made several (shaky) videos on my smart phone. As you will see from the videos, my receivers are more of the classic/old type, but reception was good with my home made antennas.

Details of my receivers, antennas and location are on the youtube videos.
I have posted one of reception from Wooferton on 5985 kHz Am, and one of
reception from Ascension on 7360 kHz AM.
I also heard Dhabayya with a good readable signal, but the first two were the best signals best with me.

Listening to the 2017 BBC Antarctic Midwinter Broadcast from the back of my vehicle in Saint-Anne-de-Beaupré, Québec, Canada.

SWL: Thomas Witherspoon (K4SWL/VE2)
Location: Sainte-Anne-de-Beaupré, Québec
Notes:

I made a field recording of the Midwinter broadcast from an access point along the north shore of the St-Lawrence river. I used two receivers:

The  Sony ICF-SW100 which I hooked up to my portable PK Loop mag loop antenna.

The Elecraft KX2 which I hooked up to a NASA PA 30 multi-band compact wire antenna that I suspended in a tree.

None of the frequencies used for the Midwinter broadcast were ideal for my location and time of day (after all, these broadcasts target Antarctica!) but last year I did successfully receive the 41 meter band broadcast.

The KX2/NASA PA 30 provided the best reception results, but sadly the recording turned out quite poor due to an incorrect setting on my Zoom H2N digital recorder.

Fortunately, I did make the following video of my Sony ICF-SW100 in action:

SWL: Nace Magner
Location: Bowling Green, Kentucky
Notes:  I listened to the signal on 7360 kHz from the back porch of my home in Bowling Green, KY. I used a 35′ end-fed external antenna located about 20′ up in a tree. I received a similar quality signal using the external antenna with a Kaito 1103 radio. I also received the signal on the Kaito using only its whip, although the signal was substantially weaker.

Thank you for your excellent work on the SWLing Post.

SWL: Jon Pott
Location: Michigan
Notes:  My first attempt at catching the Midwinter broadcast; I wasn’t expecting to pick up anything at all, but the Ascension Island location came through well enough that I could positively identify it when I compared to BBC’s recorded broadcast.

Recording of my reception (the beginning of the recording corresponds approximately to the 4:00 mark in the BBC recording below).

Location was western Michigan in the U.S.
42°46’40” N
86°03’48” W
Elevation: Approx. 212m ASL

Once again, many thanks to all of you who submitted your recordings of the BBC Midwinter Broadcast!

Video: Lightbulb vs Radio Beacon by Thomas Cholakov (N1SPY)

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

My 11 year old son Tommy (N1SPY) completed a project where he compared a 1W lightbulb to a .25 W radio beacon that he put together and bet that the radio beacon can be heard around the world. I asked him to document his activities as he went along. The project took a couple of months but is now complete and we stitched together a video of his activities.

Wow–Tommy, you’ve done an amazing job here!

I especially like how you’ve taken time to explain the principles behind the various steps of the process. Brilliant job!

Tommy, your future videos are always welcome here. Keep up the good work and we’d love to hear how many new countries you’ve racked up on your WSPR system!

Carl Laufer’s RTL-SDR on HamRadioNow

Carl Laufer isn’t a ham (yet), but he got caught up in the RTL-SDR craze in his home town, Auckland NZ, as he was completing his PHD

He began writing about them, and selling them, on his blog at www.RTL-SDR.com, and soon discovered that the little SDR receiver dongles could stand some improvement.

So he designed ways to make them work better, and contracted a Chinese manufacturer to build them with his mods. That just about doubled the price, from $10 to about $20. Yeah, big deal.

TAPR invited Carl to come to the 2017 Dayton Hamvention to talk about them at both their Friday Forum (part of HamRadioNow Episode 324) and as the main speaker at the TAPR/AMSAT Banquet.

And we got him for a conversation with HamRadioNow’s KN4AQ and PhasingLine’s Chicken With Fries in the SIB back in Tent City.

I got to meet Carl at the Hamvention this year–what a great guy and his website is certainly the best source of information about the RTL-SDR.

I should note that I also met with contributor, Mike Ladd, in person at the Hamvention. Mike now works for SDRplay.

This is one of the great things about gatherings like the Hamvention–it brings together so many people that you’d otherwise likely never meet in person!
