“Enjoy your blog. I have been reading it for years. [H]ere is something your readers might be interested in that I mentioned in my blog today:

Very cool! Goes to show that there are a countless number of applications for the Arduino system to be used with amateur and shortwave radio.

Click here to read Stan’s informative post, and here to order the TASS system from TAPR.

John Ackermann also produced this informative presentation/video about the system:

Craig Seager’s review of the Dansk RX4000 receiver

Dansk ReceiverMany thanks to SWLing Post reader, Rob Wagner, who writes:

Craig Seager is one of Australia’s finest SWL DXers, a longtime listener with great experience on shortwave, mediumwave and other modes. His amateur radio callsign is VK2HBT. Craig also has another special interest – old radio receivers. He has personally restored many fabulous radios to full working order and has accumulated a fine collection of his own. His knowledge of communications receivers is extensive.

The Mount Evelyn DX Report blog is delighted to welcome Craig who, over the next few months, will regularly contribute a new series called Retro Receiver Reviews – a look at some common and not so common communications receivers from the past. This series will be of interest to both amateur radio operators and shortwave listeners.

Craig’s first review has just been published, covering a radio not often seen these days – the Dansk RX4000 receiver. Check it out at:

Thanks for passing this along, Rob!  That Dansk RX4000 sounds like a robust receiver, with a bullet-proof front end. A nice addition to any collection.

Jeff gives high marks to the Sangean PR-D4W

Sangean

My pal, Jeff McMahon, over at the Herculodge, has just posted a video review of the Sangean PR-D4 portable radio. In summary, he writes:

“It’s a great radio with top FM, AM, and speaker sound. It blows away my C.Crane Radio-2E. Lack of illumination, however, makes it less than ideal as a bedside clock radio.”

Wow! I’m most impressed that Jeff places the PR-D4W (which retails for $69 on Amazon) above the venerable CCRadio-2E (which retails for $169 on Amazon) in terms of AM performance.

I just checked and it appears that Universal Radio also retails the PR-D4W for $69.95.

Video: “The very particular world of amateur radio”

BBC-Yaesu

Many thanks to SWLing Post reader, Nick, for sharing this 2013 video produced by the BBC. Here is the description from YouTube:

“In the face of the internet, mobiles and instant messaging you might expect the hobby of amateur radio – or HAM radio as it’s also known – to be on the decline.

But in the last three years, the number of amateur radio licences has risen by over 8,000 – with 80,000 currently issued in the UK.

Using designated frequencies, amateur radio enthusiasts communicate with people over the world. Many prefer the relaxed approach of ‘rag chewing’ or chatting at length with people, who often become friends – while at the opposite end of the spectrum ‘contesters’ compete to make as many contacts as possible in a given period.

The hobby is also a public service, with Raynet (in the UK) stepping in during emergencies when regular communication networks fail. Amateur radio enthusiasts are currently contributing to relief efforts following Typhoon Haiyan in the Philippines.”

The demise of longwave could lead to the end of the Shipping Forecast

Many thanks to SWLing Post reader, Erica, who writes:

“I saw this article about the demise of the Shipping Forecast on Radio 4 Longwave and thought readers might be interested:

http://www.telegraph.co.uk/culture/tvandradio/bbc/11892805/End-of-Shipping-Forecast-on-long-wave-radio-could-leave-sailors-high-and-dry.html

I’m not a fan of DAB radio and my bedroom radio aerial has to be positioned just so to get radio 4 FM with cclarity, so I will be disappointed if Longwave eventually gets switched off. That’s not to mention all the people–however many there may be–who don’t have easy ways to get weather info out at sea.”

Here’s an excerpt from The Telegraph:

It has kept sailors safe on the ocean waves for 90 years, becoming just as much a part of national consciousness as cricket, cups of tea and The Archers.

But the days of hearing the Shipping Forecast out on a boat may be numbered thanks to the demise of long wave technology, a veteran announcer has said.

Peter Jefferson, who read the Shipping Forecast to Radio 4 listeners for 40 years, said the “very old” transmitters which worked on long wave could soon be retired.

If that was to happen, he said, anyone more than 12 miles from the coastline would be unable to hear the shipping forecast on long wave, ending a Radio 4 tradition dating back to 1924.

Speaking at the Radio Times Festival, in Hampton Court, Mr Jefferson said the soothing tones of the Shipping Forecast would then be left to its many fans who choose to listen to it from their homes in lieu of a “sleeping pill”.

“Long wave reaches much further than FM, it’s as simple as that,” he said.
“So FM would be totally useless for shipping beyond 12 miles from land.

[…]A spokesman for the BBC said they were no firm plans to end long wave broadcasting, and no date set for when the technology could run out.

The service currently reaches as far as south-east Iceland, and is occasionally picked up as far as 3,000 miles away.

Read this full article at The Telegraph online.

Of course, I haven’t heard the Shipping Forecast on longwave since moving back to the States from the UK. Still, I would be very sad to hear the program and the longwave medium fall silent.

I would like to start adding some Shipping Forecast programs on the Shortwave Radio Audio Archive where we also curate select mediumwave and longwave recordings.  If you have the means to record episodes on longwave, please consider helping us!

The Sangean ATS-909X: Marty’s bedside radio review

SWLing Post reader, Marty (W5MRM), comments:

I recently picked up a Sangean ATS-909X to use as a bedside radio.

This blog post inspired me to put together a video review of the ATS-909X as a bedside radio. The video review can be found on my youtube page [or via the embedded player below]:

Great video, Marty, and thanks for the thorough review!
