Buying a BMW in South Africa? Shortwave radio is an option!

bwm-swSWLing Post reader, Bob, has a relative who works for BMW in the United States. Recently, Bob learned that some models of BMWs shipped to South Africa have a shortwave radio option.  He followed up with this photo of the radio display [see above].

Wow, what a fab idea! Not only would I love to have a factory-installed shortwave radio in my car, but I must admit that I love the simple design of this digital radio dial: elegant, clean, and just a tad retro and sci-fi, all at once.

Now if I could simply afford the BMW…Sigh!

Shortwave Radio Recordings: BBC to the 2014 British Antarctic Survey

800px-Antarctica.svgAs promised, here are the recordings of the BBC World Service’s thirty minute broadcast to the British Antarctic Survey. The broadcast started at 21:30 UTC on June 21, 2014 and was broadcast on 5,875, 5,985, 7,350 and 9,890 kHz.

As in previous years, this broadcast was lighthearted, filled with humorous shout-outs from the team’s family and friends. Even a couple of special guests were included. Listen for yourself:

This excellent recording was made by SWLing Post reader, Dominik, in Europe:

Post reader Rob Wagner (VK3BVW), in Australia, could receive the broadcast on three frequencies (5,875, 5,985, and 7,350). He’s included clips of each broadcast on his excellent blog, The Mount Evelyn DX Report.

As for me, I was traveling to visit family yesterday afternoon when the broadcast started.  I knew from listening endeavors on previous visits that receiving a broadcast indoors at their home is not feasible; there is some sort of power line noise in that area that overwhelms anything on the short or medium wave bands, unless the station is very strong.

To cope with this noise, I knew I would need to move my operation outdoors, away from the house, and employ an outdoor antenna. So I packed the following, all into my small flight case: the CommRadio CR-1, a NASA PA-30 15 foot passive wide-band wire antenna, and the Zoom H2n Handy Recorder
.

CommRadio-CR-1-Zoom-H2N-BBC-Antarctica

I hung the PA-30 antenna in a nearby tree, spread a wool army blanket on the ground for lounging, and put the mini flight case to use as a stand to hold the radio and recorder. The CR-1 required no external power supply, as its internal battery had been charged in advance (one of the reasons I love this little receiver for travel).

To try out the set-up, I tuned around the bands. Conditions were rough, thunderstorms were in the region, but I was most impressed that I could hear several broadcasters on 31 meters. I knew that the BBC broadcast would be a tough catch; after all, none of their transmissions were targeting my part of the globe–rather, the opposite!

When I tuned to the BBC broadcast on 7,350 kHz, here’s what I heard:

This is (very) rough copy; for five or so minutes, you’ll hear me switching between AM/USB and LSB to find the best mode for the signal. I also check the other BBC frequencies to see if any were more audible.

In the end, using ECSS (zero-beating the signal in USB) seemed to work best.

For fun, I had also brought along the Tecsun PL-660–a choice portable radio for weak signal DX. I tuned to 7,350 and could just hear the BBC signal in the noise, but voice and music were unintelligible.

What did I get out of the experience?  Good copy?  Alas, no.

But there’s nothing like the fun of playing radio outdoors! Even though the copy was rough, propagation deplorable, and static crashes abundant, I thoroughly enjoyed the experience.  Moreover, I was amused to note that while I listened (and sweated) outside in the very hot, muggy conditions of the American southeast, a few scientists huddled near the extremely chilly southern pole at that exact moment, were tuning in the exact same broadcast.  It somehow made the heat bearable.

That’s the remarkable camaraderie of radio: truly, a wireless community.

Happy Summer/Winter Solstice: Listening to New Zealand and Australia

Australia-NewZealand

I’ve been on the road a lot lately. A lack of time resulting from this, combined with frequent afternoon and evening thunderstorms when I am home, has meant that I’ve not had the radio time I often enjoy.

This morning,  I woke up around 5:50 AM determined to get a bit of time on the radio. After all, today is the first day of summer here in the US, and a special day for me. I walked outside and hooked my antenna back up; I had been forced to disconnect it yesterday as pop-up thunderstorms persisted throughout the afternoon and evening.

I then brewed a cup of coffee and settled into my “listening lounge” for some early morning tuning.

Elad-FDM-S2-Coffee

I started off this morning off by tuning the Elad FDM-S2 to Radio New Zealand International on 9,890 kHz in DRM (Digital Radio Mondiale). I was treated to one full hour of Peter Fry’s Saturday Night music; the DRM lock was completely stable.  Though I prefer the sonic characteristics of AM over digital modes, I’m most impressed with the audio quality DRM affords coming from a 50 kW signal being broadcast on the other side of the planet. The quality is so exceptional that, if you listen carefully, you can even hear the news reader shifting papers at the top of the hour.

That got me thinking: I’m flawlessly receiving and decoding a wireless digital audio signal from 13,500 kM away. Amazing. Especially considering that my laptop struggles to receive Wi-Fi in many hotels.

RNZI signed off after an hour, so I switched modes to AM and tuned to Radio Australia on 9,580 kHz.

BombersAs I had hoped, RA was broadcasting the second half of the AFL match featuring the Essendon Bombers who ultimately held a nine-point win over the Adelaide Crows. Alas, Radio Australia dropped the signal before the end of the final quarter, but I was able to watch the results roll in on my iPhone while making waffles in the kitchen. If this had been a World Cup match, I would have scoured the shortwaves for another Radio Australia frequency.

Immediately after tuning in RNZI, I hit the record button on the FDM-S2 (around 5:55 EDT/9:55 UTC) and didn’t stop the recording until after Radio Australia signed off, so there is a 30 second silence in the middle while I tuned and switched modes from DRM to AM.

Depending on which hemisphere you live in, I hope you enjoy this summer–or winter– solstice.

As for me, I’m looking forward to a happy birthday with my family.  Cheers!

Testing SDR#’s noise reduction in a London park

LondonShortwave-ParkSDR

Yesterday, SWLing Post reader London Shortwave took his laptop, FunCube Dongle Pro+, and 6 meter long wire antenna to a local park where he tested SDR#‘s new IF noise reduction.

He made the following screencast/video where he toggles the IF noise reduction feature while receiving the BBC World Service’s Pashto language service on shortwave:

Most impressive! Indeed, I believe SDR#’s noise reduction might rival that of OEM applications. While I’m not the biggest fan of noise reduction for everyday use (due to inherent digital artifacts) it is a valuable tool when noise levels are high.

If you would like to experiment with SDR#, click here to download your free copy. SDR# has a number of additional plugins and dedicated users/developers who communicate via this this Yahoo! Group.

Many thanks to @LondonShortwave.

Any other readers using SDR#? Please comment.

Looking for a weekend radio project? Check out MakeRF

MakeRF-LogoThis year, at the 2014 Dayton Hamvention, I had the pleasure of meeting a number of SWLing Post readers–truly a highlight for me at the convention.

One of the readers I met was Mike Gualtieri (KB3TKG). Mike and I had a great conversation about pirate radio, ham radio and shortwave listening.

I also learned that, one year ago, Mike started MakeRF: a blog devoted to making radios and accessories. He has already documented several savvy projects:

I encourage you to bookmark MakeRF and even give one of these simple projects a go. Many thanks, Mike!
