Many thanks to SWLing Post reader, Marc, who shares this news from Radio France.

The article (in French) notes that as of midnight on December 31, 2015, Radio France will cease all mediumwave broadcasts permanently. Up to this point, Radio France’s mediumwave transmitters have broadcast France Info, France bleu RCFM and France Bleu Elsass.

The article notes that regions previously within the broadcast footprint of their mediumwave transmissions are now serviced via FM and/or online streaming.

Ukraine to launch radio station for troops

Disputed Ukraine Map via Wikimedia CommonsMany thanks to SWLing Post reader, David Iurescia (LW4DAF), who shares this article via Sputnik News:

Ukraine plans to launch a new radio station for the military in 2016.

Alexei Makukhin, an advisor to the Ukraine’s Defense Minister, said during a press briefing that a new Ukrainian radio station for military personnel will begin operating on March 1, 2016.

“It’s no secret that our troops on the frontline often suffer from an information vacuum,” Makukhin said. “So we need a radio station. Seventy percent of its content will be music; there will also be news broadcasts and programs for the troops – where soldiers can say hello to their friends and relatives, request songs and share stories live on air.

There will also be programs featuring interviews with experts and military personnel.”

The new radio station will be reportedly funded by Spirit of America, a non-profit company which assists US military personnel deployed in Iraq, Afghanistan and Africa.

Fessenden Christmas Eve Commemorative Transmissions

7 Replies

Embedded image permalink

This  was reported in the ARRL Newsletter:

Brian Justin, WA1ZMS, will again put his 600 meter Experimental Station WG2XFQ on the air on for a Christmas Eve commemorative transmission. WG2XFQ will transmit on 486 kHz from Forest, Virginia, to mark the 109th anniversary of Reginald Fessenden’s first audio transmission. Historic accounts say Fessenden played the violin — or a recording — and read a brief Bible verse. It’s been reported that other radio experimenters and shipboard operators who heard Fessenden’s broadcast were astounded.

Justin will conduct a run-up to this year’s event starting at around mid-day Eastern Time on December 23. The “official” Christmas event will begin on December 24 at 0001 UTC (the evening of December 23 in US time zones) and will continue for at least 24 hours. Justin said he plans to repeat the commemorative transmissions on New Year’s Eve and on New Year’s Day.

Fessenden’s transmitter was an ac alternator, modulated by placing carbon microphones in series with the antenna feed line. Justin’s homebuilt station is slightly more modern, based on a 1921 vacuum tube master oscillator power amplifier (MOPA) design. Listener reports are appreciated and may be sent directly to Brian Justin, WA1ZMS, at his QRZ.com address. (Brian Justin, WA1ZMS, built this replica circa-1920 transmitter, capable of CW and Heising modulated AM.      Photo by Brian Justin)

While I have not heard Brian’s transmission before, I have actually heard a transmission on the experimental frequencies between 465 – 515 kHz. I never expected to be able to hear anything due to extremely high local noise, but one night the propagation gods smiled upon me and the evening was exceptionally quiet. I listened on my Elad SDR receiver over and over to the Morse Code signal which was extremely weak, but mostly readable. I confirmed with Multipsk software, verifying I was indeed hearing one of the experimental stations out of Connecticut.

For information regarding the 500 KC experimental project you can follow this link.

Why not give a listen? You just might be surprised like I was to hear something on this band, and you could add a little Christmas Eve radio memory to your collection!!             73, Robert

Phil’s initial impressions of the Degen DE27

Degen-DE27

Many thanks to SWLing Post reader, Phil Ireland, who comments:

I’ve just received my Degen DE27 from China. Interesting little radio, I haven’t had a good chance to put it through its paces yet but my initial impressions are the radio seems well built and fairly intuitive to turn it on.

However, all the instructions are in Chinese so luckily there was someone in my office who could set the language to english otherwise, setting up the radio is a nightmare! I will have to take the radio outside to test its performance as the office environment is useless to listen in.

The box says the radio tunes from 3.2 mhz to 21.850 mhz however, I havent been able to work out how to make it tune out of the standard SW Broadcast Bands yet. Toggling between 10 khz and 9 khz steps for AM is easy as it setting the FM band coverage but I’m yet to determine the SW settings. It appears tuning is only in 5 khz as well on SW.

As for venturing into MP3 settings and recording, I’ll leave that, it seems too much of a challenge! The clock and calendar, sleep timer, alarms are all fairly straight forward but there is an “E-Book” setting which defies description! It has a USB flash disc function and inputs for a micro SD card. Charging the supplied Lithium battery is via a supplied USB cable.

The display is easy to read and attractive with excellent backlighting. I’m not expecting stellar performance on any band, after all, it was a cheap radio (about 40 AUD with free postage) but it is built around DSP architecture. Only a single bandwidth is available and there is no SSB capabilities. The radio hopefully will be ideal to throw onto a backpack or pocket as a travel portable.

If DEGEN read these comments, perhaps an English manual put online would be extremely helpful to allow users to get the most out of the DE27.

I’ll comment more on the performance later but for now, the radio shows promise.

Thanks so much for sharing your initial impressions, Phil! Please keep us informed as you discover more about this little radio!

This reminds me that I have yet to put my Degen DE221 through the paces. Stay tuned!

Historic Ocean Gate antenna field may be removed

Leave a reply

GoodLuckPointMany thanks to SWLing Post contributor, Ulis K3LU, for sharing the following story from newsworks.org:

Pole removal project planned for Good Luck Point tidal marshlands

The iconic poles emerging from the tidal marshes in Bayville’s Good Luck Point may soon disappear if a federal plan clears a historic preservation hurdle.

A plan funded by the federal Disaster Relief Appropriations Act of 2013 calls for the removal of hundreds of poles along with cables, wires, metal towers, and concrete blocks that sit within Barnegat Bay marshlands at the foot of the Toms River.

“The goal of this action is to enhance coastal marsh habitats by increasing marsh resiliency from impacts of large storm events and other ecosystem stressors,” according to a U.S. Fish & Wildlife Service release.

The poles are a component of inactive shortwave antenna fields associated with AT&T’s ship-to-shore shortwave communications system, which was in operation at the sites from the early 1930s until 1999, according to the release.

The area also includes a shortwave transmitter building and antenna field. Under the call sign “WOO,” the station helped broadcast Voice of America around the globe after 1944 and enabled communication with ships at sea throughout the twentieth century.

Best solution to restore a vintage plastic radio chassis?

20 Replies

Sony-ICF550W-FrontFriday, I brought home an untested, slightly grimy, Sony ICF-5500W. I purchased it through Goodwill for $20.

Sony-ICF550W-Right

I crossed my fingers as I put three C cells in the radio and turned it on. Fortunately, I was rewarded with brilliant audio. I tuned the ‘5500W on AM/mediumwave and heard CFZM,  500 miles to my north, and Radio Reloj, 860 miles to my south. A quick scan on the FM dial revealed that I could also hear all of my local benchmarks. Whew!

Other than the dial needing a little calibration, and DeOxit on a few pots, it’s in excellent mechanical shape.

Sony-ICF550W-Left

I started cleaning the radio last night using Q-tip cotton swabs and a vinegar/water solution.

I’d like to restore the hard plastic chassis’ original shine, though.

I was tempted to reach for some Armor All, but stopped myself short. I know it would give the ICF-5500W a nice shine, but would it cause any long-term damage to the black plastic or clear dial cover?

I know there are vintage radio restorers among the SWLing Post readership. Can someone offer advice on what’s the best product to use (or not use!) on my ICF-5500W?

If you have experience, please comment!
