SWLing Post contributor, Mark Fahey, has just announced that his new Beaglebone-powered KiwiSDR receiver is online.  Mark notes:

Please try out my multi-user 0-30MHz SDR[.] The test system is operating from my monitoring station at Freemans Reach in south east Australia (near Sydney).

[…]The test system is fully self contained and self operating. The antenna (ALA1530S+) we are using is a magnetic loop with an impedance tracking amplifier designed and manufactured by Wellbrook Communications, Llanwrth Wells in Wales. The receiver and CPU is the result of the Kickstarter funded project “KiwiSDR” which was conceived and designed by John Seamons ex Pixar and Lucas Films.

[…]You can use Chrome, Microsoft Edge, Safari, Firefox – but Internet Explorer is not supported at this stage. Tune in on this URL…

Many thanks for sharing your KiwiSDR, Mark! Though demand has been quite high, I have managed to claim one of the four user seats on Mark’s SDR and “listen like a local.”

Mark: you’ve done a great job making a proper listening post for your remote listeners. The KiwiSDR/Wellbrook ALA1530S+ combo is performing admirably!

New Brunswick town “haunted by the radio”

unnamed

I’m very happy to see that the CBC has reported on the premier of Amanda Dawn Christie’s film, Spectres of Shortwave.

(Source: CBC)

For seven decades, a mysterious site on the Trans-Canada highway marked Sackville, New Brunswick. Where the hills and trees faded just past the Nova Scotia border, 13 120-metre towers rose up from the town’s Tantramar Marsh. They encompassed CBC’s Radio-Canada International (RCI) shortwave broadcasting site, built during the Second World War to send broadcasts worldwide.

Like others in the area, artist and filmmaker Amanda Dawn Christie was fascinated by the site — which not only transmitted Canadian content around the world in various languages, but also relayed Radio Free Europe broadcasts during the Cold War. This week, she’s premieringSpectres of Shortwave, her experimental documentary film on the site, at the Atlantic Film Festival in Halifax. It’s a project seven years in the making.

“[The transmission site’s] purpose wasn’t for the locals,” Christie says. “So my interest was in what its relationship was to the local people who lived around it.” That relationship was more than just landscape: the transmission site affected the appliances, homes and even dreams of local residents.[…]

Rare Hitachi KW-WSI WorldSpace Receiver on Ebay

This is the first and only “WorldSpace” satellite receiver I’ve seen on Ebay, currently offered at a $175 Buy-It-Now price from a seller in Australia:

http://www.ebay.com/itm/HITACHI-KW-WSI-DIGITAL-RECEIVER-WS-FM-MW-SW1-SW2-/282192383263

The radio is listed as in excellent condition with the original box and literature. Besides the long-gone WorldSpace satellite frequencies, the radio covers medium wave, FM, and most of the shortwave range. A brief PDF data sheet for the radio gives a description of features and operations.

hitachi-kw-wsi

Wikipedia describes this radio’s satellite service as 1worldspace, formerly known as ‘WorldSpace’, is a defunct satellite radio network that in its heyday provided service to over 170,000 subscribers in eastern and southern Africa, the Middle East, and much of Asia with 96% coming from India. It was profitable in India, with 450,000 subscribers.

I wonder if the Hitachi KW-WSI is a reasonable performer for shortwave listening? Does anyone know any technical details of this receiver?

Many thanks to SWLing Post contributor, London Shortwave, who shared a link to this Sony CRF-V21 on eBay:

I’m sure a Sony collector will eventually snag this rig. Thought the listing mentions no shipping outside the UK, the Seller states otherwise:

“[I]f you don’t live in uk you can arrange a courier at your own cost”

Do any SWLing Post readers own the CRF-V21? Please comment!

Great Smoky Mountains National Park: Four NPOTA activations planned today

npota-tr10-pk01-qrp-elecraft-kx2-clipboard

Around noon (EDT) today, I’ll start my short journey to the W4DXCC conference in Sevierville, TN.

En route, I’ll pass through three National Parks: the Blue Ridge Parkway, The Appalachian National Scenic Trail and the Great Smoky Mountains National Park. It’s a beautiful drive and the weather appears to be near-ideal–clear skies.

ARRL-NPOTAThis also affords me the opportunity to activate two “two-fers” for the National Parks On The Air  (NPOTA):

  • Blue Ridge Parkway and Great Smoky Mountains Park (PK01 & NP26)
  • Appalachian Trail and Great Smoky Mountains Park (NP26 & TR01)

I’ll only get credit for three activations, but chasers will have a better opportunity to snag two park entities in one QSO.

I plan to activate the PK01 & NP26 two-fer starting around 17:00 UTC, then the NP26 & TR01 two-fer starting around 19:15 UTC. Look for me on 14,286 and 7,286 +/- 6 kHz.

SWLs: please comment if you happen to hear me at your location!

On the way back from the conference, Sunday morning, I plan to activate the same sites once again (weather permitting).
