Bruce believes the CC Skywave is an ideal travel radio

The C.Crane CC Skywave

Many thanks to SWLing Post reader, Bruce Atchison, who recently shared his positive comments about the CC Skywave. Bruce writes::

This is a lot of radio for such a small size. The CC Skywave is a great travel companion because of its portability and price.

Moreover, it’s rich with features. The receiver tunes in AM and FM as well as all the shortwave bands, NOAA weather channels, and the aircraft band. The latter comes in handy while you’re waiting for flights so you can find out immediately and directly what is delaying them.

It also has a built-in alarm clock so you needn’t miss the next morning’s activities.

The Skywave runs on 2 AA cells and can be set to charge NiMH rechargeable batteries. Its mini-USB port lets you use the AC adaptor or 12 volt cigarette lighter adapter. You can even use one of those cell phone solar panels to power the set.

This radio’s reception is excellent and its filters allow for eliminating adjacent channel interference. Apart from its rather high noise floor on AM, the receiver pulls in stations at night very well.

The Skywave can also add local stations to its memory pages automatically. This comes in handy in foreign cities when you don’t have time to manually scan the AM and FM dial.

This is truly a globe trotter’s accessory. You can set it to European AM channel spacing and the Japanese FM band. The radio even has a fine tuning setting for oddly-spaced stations.

The three amber LEDs light up the dial nicely and they turn off automatically after about ten seconds to conserve battery life. In fact, the Skywave is amazingly energy efficient.

Whenever I travel, this radio is one thing I’ll be sure to pack. It’s all I need when I travel away from home.

Thanks for sharing your thoughts, Bruce.  Yes, I believe the Skywave is a great little travel radio, too. One of the Skywave features I used extensively while off-grid in Canada this summer, was the weather radio function (Environment Canada and NOAA frequencies are the same). Without Internet, it was an excellent, handy source of weather information.

WRMI to showcase digital modes via analog radio

WRMI, Radio Miami International, will showcase digital text and images via analog radio in a half-hour special broadcast to be transmitted nine times (at least), beginning Saturday, 13 August.

The broadcast will mostly be in MFSK32 centered on 1500 Hz. There will also be segments in MFSK64, MFSK32 centered on 2200 Hz, and Olivia 64-2000. The program will include MFSK images, examples of non-Latin alphabets, and an Flmsg transmission. You will also hear “co-channel” music.

To decode the modes on the WRMI broadcast, Fldigi software is recommended. Download it fromhttps://sourceforge.net/projects/fldigi/files/fldigi/ . The main Fldigi website is http://www.w1hkj.com.

And you will use the companion program Flmsg. Download it fromhttps://sourceforge.net/projects/fldigi/files/flmsg/ .

To make Flmsg work with Fldigi, in Fldigi: Configure > Misc > NBEMS > under Reception of flmsg files, select Open with flmsg and Open in browser, and below that indicate where your Flmsg.exe file is located – probably somewhere in Program Files(x86).

For correct decoding of the languages with diacritics, or using non-Latin alphabets, in Fldigi: Configure > Colors & Fonts > RxTx > in the Rx/Tx Character set menu, select UTF-8.

For Fldigi to automatically select the mode and the center audio frequency of the mode, select RxID (upper right of the interface) by left clicking. In newer versions of Fldigi, also right click on RxID and select Passband.

You can decode this WRMI special broadcast as it is broadcast, or from your recording.

USAF wants to release ionized gas in the upper atmosphere to improve HF

Earth

(Source: Southgate ARC)

New Scientist magazine reports the US Air Force is working on plans to improve HF radio propagation by releasing ionised gas in the upper atmosphere using a fleet of micro satellites

As well as increasing the range of radio signals, the USAF says it wants to smooth out the effects of solar winds, which can knock out GPS, and also investigate the possibility of blocking communication from enemy satellites.

The story says there are at least two major challenges. One is building a plasma generator small enough to fit on a CubeSat – roughly 10 centimetres cubed. Then there’s the problem of controlling exactly how the plasma will disperse once it is released.

Ecos del Torbes special broadcast August 12 & 15

special program Ecos

Many thanks to SWLing Post reader, Rafael Rodríguez R., who writes with the following announcement from Bogotá, Colombia:

[I would like to announce a] DX program, celebrating “International Day” from Ecos del Torbes (emblematic Venezuelan station) and also the 40th anniversary Club Diexistas de la Amistad and their program América en Antena (celebrating 26th anniversary).

This will be a 30 min. program with reviews about the club, program and station, and historical audio from Ecos del Torbes.

This special program will be verified with a e-QSL

Note that Rafael sent this announcement in July while I was traveling and I missed posting before the August 8 broadcast date. Thankfully, we still have the August 12 and 15 broadcasts! Thanks again for the announcement, Rafael!

 

Experience with Heros Technology Ltd UK VLF Up-Converter?

VLF-LF-Upconverter

Many thanks to SWLing Post reader, Michael Vitale, who (several weeks ago–!) asked:

Has anyone ever dealt with the equipment from Heros Technology Ltd UK specifically their VLF converters models 350-400? Their claim is these converters will work with any receiver (SW) on the market past or present.

Click here to view the video introduction to the VLF-LF Up-Converter.

I, personally, have no experience with VLF/LF up-converters, so I’m hoping someone else can help Michael.  Please comment!

Hello all,

A few nights ago during great propagation in the Medium Wave band I had the opertunity to DX Radio Capital from Lima, Peru all the way to Northern Ireland. I was planning to sleep early but favourable conditions on MW prompted me to have a late night to chase DX. I have had this confirmed to me by a few very well known MW DX’ers.

Swlingperumw

The equipment I had used to get this catch were as follows ;

• Lack of sleep & plenty of caffeine

• SDR Play RSP with ferrite chokes

• Wellbrook ALA1530LN Active Loop Antenna with coax running out of the electric field of my house and ferrite chokes attaches at parts

The Classics Experience with Paul Walker: August 26 and 27

SX-99-Dial-Nar

Many thanks to SWLing Post contributor, Paul Walker, who announces his next show:

The next broadcast of The Classics Experience with Paul Walker is going to be the biggest yet. It’ll all take place in late August with 2 hours of rock n roll music with maybe a few country songs thrown in for good measure. The show is ALL about the music and providing something different on the shortwave bands, so all you’ll get from the show is MUSIC. There will be NO rants, raves, personal opinions or political and religious rants. No commercials or sponsors either. I fund the broadcast out of my own pocket so I can pick whatever music I want and not have to answer to anyone but George D. Beagle!

WRMI 7570kHz Saturday August 27th 0400 to 0600UTC. Beaming at 315 degrees towards Vancouver. It should provide a good signal to the West Coast of the US and Canada and probably parts of the midwest and upper midwest along the way.

WRMI 11580kHz Friday August 26th 2100 UTC to 2300UTC., This signal target area is Eastern North America and Western Europe.

WRMI 11530kHz Saturday August 27th, 0200UTC to 0400UTC targetting South America with maybe a little spill over to extreme Western Africa.

WINB 9265kHz Saturday August 27th 0330 to 0530UTC. This should provide good coverage into the Midwest, parts of southern Canada, into Mexico along with parts of Central & Southern Europe it seemed.. It was weakly heard in Australia and New Zealand during my last broadcast.

Channel 292 6070kHz Friday August 26th 2200 to 2400UTC. This should provide good coverage of central and parts of Western Europe.

Shortwave Services 15195khz via Armenia Saturday August 27th 1200 to 1400UTC. Beaming at 65 degrees towards Japan.

I am going to suspend my request for $ to cover postage and QSL costs. I’ve been so lax in sending out QSL cards, I haven’t gotten around to any of them from previous broadcasts and have gotten a few nastygrams about it. I feel bad, so I won’t ask for any money to cover costs this time around.

There may be MFSK32 data and pictures during the broadcast. I will announce during the broadcast if and when that happens.
