Buy a hi-tech sailboat, complete with shortwave radio

The Nomadness

The Nomadness

With all of the recent posts on maritime radio, I can’t help but jump slightly off-topic for a moment…

I just learned that SWLing Post reader, Steven Roberts, is selling his completely geeked-out sailboat: a 1987 Amazon 44 called the Nomadness. ( Steven knows “geeked-out” is a compliment!)

Steven has put a lot of time and engineering love into the Nomadness and has documented how he’s customized her on his popular blog, Nomadness.com. She’s a beauty.

You can read about the sale of the Nomadness on the boating blog Three Sheets Northwest. If you live in the Pacific NW, you might check her out.

Work the NASA Spacecraft Juno (and get a QSL card)!

EFB_publicmap1-675Many thanks to SWLing Post reader, Troy, who emailed us about a really fun and unique opportunity for amateur radio operators:  to send the NASA spacecraft Juno a Morse Code greeting [specifically, “HI”] when it passes over Earth tomorrow, starting around 18:00 UTC.

The NASA Jet Propulsion Laboratory explains:

“NASA’s Juno spacecraft will fly past Earth on October 9, 2013, to receive a gravity assist from our planet, putting it on course for Jupiter. To celebrate this event, the Juno mission is inviting amateur radio operators around the world to say “HI” to Juno in a coordinated Morse Code message. Juno’s radio & plasma wave experiment, called Waves, should be able to detect the message if enough people participate. So please join in, and help spread the word to fellow amateur radio enthusiasts!

This page will be updated with additional information as the event approaches. In addition, we have created a Facebook event page where you are welcome to a discuss[ion of] this activity.”

ham_morsecode_ditsTo be clear, this is a coordinated and unified message to the Juno craft; there will be no opportunity to hear a response from it.  Rather, the Waves instrument data containing the message will be shared by the Juno team after the flyby.  But still, what fun!

If you’re a licensed ham, and this sounds like something that you’d like to be part of, please check out the the NASA JPL page dedicated to this event. It has all of the information you’ll need to transmit to Juno, including a countdown clock–or to simply listen to everyone who does. Be sure to check out Juno’s Technical FAQ (click on the FAQ link) which answers a lot of the questions participants have already asked.

I’ll certainly do my best to be a part of the unified greeting to Juno.

I should note that I’m pleased to see the JPL page is running despite the US government shutdown. Many other NASA web pages have been affected.

Hi, Juno; we send our greetings!

Shutdown: Wake Island DXpedition on ice

WakeIslandI’ve been somewhat amazed at the number of ways the US government shutdown has had an impact upon radio.

Many ham radio operators are aware of the upcoming Wake Island DXpedition commemorating the 70th anniversary of the World War II massacre; everything had been arranged in advance, including payment for the flight to Wake Island. But as the last leg of the operators’ trip to Wake Island relies upon a coordinated venture with the US Air Force, just as many USAF employees suddenly find themselves on furlough, the trip has been placed on hold until the shutdown ends. This is particularly unfortunate in that DXpeditions are pricey ventures; the total cost of the Wake Island DXpedition cost each radio operator $9,000 out-of-pocket, for a grand total of $140,000 US.

I received the following message from the DXpedition on Wednesday:

To All:

Those of us on the Wake Atoll DXpedition team were scheduled to depart today for Hawaii, on our way to Wake Island Friday.

However, because of the U.S. Government shutdown yesterday, the DXpedition has been delayed. The USAF is preoccupied with sequestration activities and many staff personnel have been furloughed.

We are hoping this is a short-term delay, as we continue to pursue the approval process. As soon as a revised schedule is finalized, new dates will be posted on the Wake DXpedition website.

In the meantime, thanks to all for your continued support.

Yesterday, the DXpedition actually caught the attention of the Reuters news service:

For anyone questioning the reach of the federal government shutdown, consider Wake Island.

Not much more than military-plane refueling and classified operations occur on the unincorporated U.S. territory, a coral atoll located between Hawaii and Guam, about 6,700 miles (10,780 kilometers) from the legislative standoff in Washington.

That was about to change this week with the arrival of a dozen ham-radio operators who thought they’d won approval for a two-week commemoration of the 70th anniversary of the World War II massacre of almost 100 U.S. civilian contractors on Wake Island by the Japanese on Oct. 7, 1943.

Instead, after months of preparation, the trip is on ice because of a paperwork delay the group attributes to the partial federal shutdown, which started Oct. 1 as Republicans and Democrats failed to agree on a stopgap spending measure.

“They made it sound like it was just unfortunate timing,” said Craig Thompson, 61, one of the expedition’s leaders. “At the level that it was at, they were focused on what they had to do to shut down government, to prepare their budgets and deal with all of the other changes that were going on.”

The operation was of special interest to tens of thousands of ham operators inside and outside the U.S. The hobbyists collect contacts with all countries and islands in a practice known as DXing. Because Wake Island hasn’t had a major radio expedition since 1998, there’s great demand for its confirmation of a contact there.

All the paperwork was in place, except for final travel orders that needed one last Pentagon signature, said Thompson, an electronics company owner from central Illinois who is a veteran of radio expeditions to other remote locales, including Midway Island and Swains Island in thePacific Ocean.

[…]The U.S. Air Force manages Wake and access is restricted. The group was to fly commercial on Oct. 2 to Honolulu, where they would have then boarded a military flight today to Wake.

The decision to cancel was made late on Oct. 1 after determining the group probably wouldn’t get final approval in time to catch the second flight, flown once every two weeks.

Shortwave Radio Recordings: Radio Australia

CRI-bandwidthLike most Friday mornings, yesterday at 11:00 UTC, I tuned to 9,580 kHz to listen to Radio Australia news and ABC National’s technology program Download This Show.

While the signal out of Shepparton, Australia was as strong as ever, I heard adjacent interference from China Radio International.

Indeed, looking my WinRadio Excalibur‘s spectrum display (see image on right), you can see that CRI’s signal on 9,570 kHz was actually producing noise 15 kHz on either side of their AM carrier (for a total bandwidth of 30 kHz!). Radio Australia’s signal was much cleaner, sticking to their allotted 10 kHz bandwidth limit.

The recording of Radio Australia was still quite good, despite the interference, because I was able to run the Excalibur’s AM sync detector locked on the (less noisy) upper side band.

Document radio interference via the Ofcom Spectrum Management Survey

PLT devices can produce broad spectrum noise on the shortwave/amateur radio HF bands

PLT devices can produce broad spectrum noise on the shortwave/amateur radio HF bands

Nige (G7CNF) recently contacted me regarding a survey he has created to help document and fight radio interference from power line technology and other sources.

If you live in the UK and can create an Ofcom case reference number, please consider contributing.

I have created a new forum (or rather relaunched my old one but with some rebranding) […] dedicated to discussing and curing [radio] interference.

I was contacted recently on one of my PLT YT videos by a SWL who was suffering PLT interference and it reminded me that since 2010, SWLs have had no ‘right to complain’ in the UK after Ofcom delegated domestic broadcast interference to the BBC. Frankly I think that is unacceptable and I want to address that imbalance.

I have created a new survey, the ‘Ofcom Spectrum Management Survey.’ Unlike the previous incarnation which was aimed at radio amateurs alone, this time I have opened it up to all radio users, regardless of type; the only qualification needed to fill this survey is an Ofcom case reference number. […]

Like the RSGB noise floor monitoring campaign which has just been stepped up to incorporate the use of the Cross-Country-Wireless Sentinel SDR noise monitor, I believe that my Ofcom survey will offer insights into the regulator’s performance over over time – and highlight its deficiencies by placing Ofcom spectrum abuse cases in the public domain.

The survey can be found here:

Many thanks for your time and the best of luck with the hobby.
