The Mighty KBC will test to the USA on Sunday 11 November 2012 00.00 –
02.00 UTC on 9450 kHz!

Please join the Mighty KBC for a test of a digital text sent via a
shortwave broadcast transmitter. This will take place during the next
transmission to North America, Sunday 0000-0200 UTC, at approximately
0130 and just before the end of the broadcast at 0200.

All you need is a basic shortwave receiver (no SSB mode is necessary),
and a basic personal computer. Using a patch cord, you will feed the
audio out of the earphone jack (or line out) of your radio into the
microphone jack of your PC. If you don’t have a patch cord, you can
try placing the speaker of your radio close to the built-in microphone
of a laptop PC.

You will also need software. There are several freeware or shareware
programs used by the amateur radio community that decode digital text
modes. One is FLDIGI, available from http://www.w1hkj.com .

After installing FLDIGI, pull down the Configure menu, then click
Sound Card, and select the soundcard your PC is using.

You might also have to adjust your audio settings. In Windows 7, left
click twice on the speaker icon in the lower right of PC display, then
click Options, then click Properties, then click Recording, then click
the input that works. Other operating systems will have different
procedures. A good way to test your audio settings is to try to decode
the radio amateurs using the PSK31 mode on 14070 kHz.

For the test digital text transmissions on Sunday, The Mighty KBC will
be using the QPSK125 mode. On your software, your cursor should be
centered on 1500 Hertz, where you will see the “waterfall” of the
QPSK125 signal. You can decode the transmission while you receive it,
or record the transmission and decode from the recording. The latter
will give you more opportunities to perfect the technique.

The test to be transmitted will be a formatted html file. Copy it from
to (and including) , and paste it to a text editor (such
as Notepad in Windows). Save the file, using any file name, with the
suffix .htm or .html. Then open the file in any web browser. If all
goes well, this might be the first time you receive a shortwave radio
broadcast in color!

In the future, an app will be developed to make this process simpler!

Dear friends,

all new products for 2011

– 2011 Super Frequency List on CD

have been published by 4 December. We’ve worked around the clock and hundreds of advance orders have been mailed by Monday 6 December, i.e. well in time for the Christmas holiday and radio monitoring season. Enjoy!

Please note that we did NOT increase our prices for 2011.

Since Larry Magne’s Passport to World Band Radio has been
discontinued in 2009, our 2011 Shortwave Frequency Guide remains the only international handbook that gives you full schedule details for each entry in the unique broadcast frequency list, e.g.

4824.4 – La Voz de la Selva – Iquitos – PRU – 01.00-03.00 – Sp – dom – Mon-Sat

7210.0 – All India Radio – Kolkata – IND – 04.00-05.00 – En Hi Bg –
dom – Sat Sun

11675.0 – Radio New Zealand International – Rangitaiki – NZL – 06.59-07.58 – En – Pa – DRM

On our updated website

www.klingenfuss.org

you can download full A4 size PDF sample pages of our latest printed
products as well as the new 2011 catalogue, plus detailed product
descriptions, sample pages, screenshots, and a list of dealers
worldwide – from Australia to the United States of America!
Alternatively, you may ask for our free 24-pages 2011 printed
catalogue to your postal address.

The 2011/2012 Guide to Utility Radio Stations is the 26th edition of
this standard reference book for both professional HF radio
monitoring services and non-professional radio listeners worldwide.

Deadline for the very latest 2011 broadcast schedules published in
the brandnew Shortwave Frequency Guide was on 20 November 2010.
Unlike traditional publications in this field, our clear layout and
new typeface provides for excellent legibility. See the brandnew PDF
sample pages on our comprehensive webpage!

Apart from the usual up-to-date broadcast and utility station and
schedule databases, the 2011 Super Frequency List on CD now covers 418 fascinating new digital data decoder screenshots from
professional HF stations around the globe.

Our product Digital Data Decoder Screenshots on CD now covers more than 7,800 (seven thousand eight hundred!) digital data decoder screenshots from 1997 to today, essentially produced with WAVECOM equipment. Feed your Windows PC with this CD, and the “slide show” will keep you busy for a few days – or weeks!

WAVECOM W-CODE is a software decoder with inputs identical to the famous W61PC. It allows seamless integration with SDR (Software-Defined Radio) receivers with IQ data or digital audio outputs, and provides all functions required to analyze, decode and process data communications throughout the complete radio spectrum (HF, VHF, UHF, SHF). RADIXON’s Excalibur or MICROTELECOM’s Perseus and the W-CODE make a real dream team!

The W-CODE and W61 series of Digital Data Analyzer and Decoder
products are clearly targeted at the professional market. Typical
applications are manual or automated monitoring of radio
communication transmissions in the HF + UHF + VHF + SHF + satellite
bands, SIGINT, and signal analysis and classification. The superb new software cracks 200+ modes with worldwide leading technology.
Detailed information can be found on our website and in the printed
brochure available upon request.

As precisely predicted by ourselves – and by nobody else! – already
10 years ago in 2000, HF e-mail continues to spread rapidly and has
developed into the major application of modern digital HF techniques
that we have marketed – and used! – for years.

After Hurricane Katrina, the Indian Ocean Tsunami, and the Haiti
Earthquake, Lesson # 1 says: Forget about satphone, BPL, cellphones, e-mail and Internet. HF radio is vital!

Best wishes, Joerg Klingenfuss
