Dear friends,

all new products for 2018

– 2018 Super Frequency List on CD
– 2018 Shortwave Frequency Guide
– 2018 Frequency Database for the PERSEUS Software-Defined Receiver
– 1997-2018 Digital Data Decoder Screenshots on USB Stick
– Supplement January 2018 to the 2017/2018 Guide to Utility Radio Stations

have been published by 7 December. We’ve worked around the clock and hundreds of advance orders have been mailed by Saturday 9 December, i.e. well in time for the Christmas holiday and radio monitoring season. Enjoy!

Full A4 size sample pages can be found on our website: where you can download the new 2018 catalogue as well, plus detailed product descriptions, hundreds of fascinating screenshots, and a list of dealers worldwide, from Australia to the United States of America. Alternatively, you may ask for our free 24-pages 2018 printed catalogue to your postal address.

The free Supplement January 2018 to the 2017/2018 Guide to Utility Radio Stations with 400+ new frequencies can be downloaded from our website as well. For decades, the Klingenfuss Utility Radio Guide has been the standard reference book for both professional HF radio monitoring services and non-professional radio listeners worldwide.

Deadline for the very latest 2018 broadcast schedules published in the brandnew Shortwave Frequency Guide was on 15 November 2017. Unlike traditional publications in this field, our clear layout and new typeface provides for excellent legibility. See the brandnew sample pages on our comprehensive webpage!

Apart from the usual up-to-date broadcast and utility station and schedule databases, the 2018 Super Frequency List on CD now covers more than 570 fascinating new digital data decoder screenshots from professional HF stations around the globe, comprising in detail the revolutionary Kiwi-SDR and Web-SDR techniques as well.

Our product Digital Data Decoder Screenshots on USB Stick now covers more than 14,500 (fourteen thousand five hundred!) digital data decoder screenshots from 1997 to today, essentially produced with PROCITEC and WAVECOM equipment. Feed your PC or laptop or tablet with this stick, and the “slide show” will keep you busy for a few days –
or weeks!

As precisely predicted by ourselves – and by nobody else! – already 18 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 decades.

Best wishes, Joerg Klingenfuss

New Klingenfuss products for 2017: Worldwide Web-SDR Decoding

Dear friends,

recently, we've used Web-SDRs from all over the world for the 
monitoring of professional HF digital data stations. Decoding results 
are excellent and hundreds of screenshots will be published in our 
2017 editions - see some samples on our hotfrequencies website!

NOAA sunspot numbers now are between 0 and 100, with the solar cycle 
minimum expected for 2019. However, we still experience good 
propagation conditions up to around 21 MHz: on 13 October we received 
the low-power transmitter of aircraft A6-EOX, an Emirates AIRBUS 
A380, sending a detailed ADS-C Basic Report from high above the 
Arabian Sea at an altitude of 40,000 feet, on 21982 kHz. HF radio 
continues to be fascinating!

busy for a few days - or weeks!

Bob Grove W8JHD, Review Editor, in The Spectrum Monitor, United 
States of America - February 2016: "For the consummate monitor of the 
radio spectrum, two major sources dominate the frequency directory 
compendium. For scanner enthusiasts it's the 
website, and for shortwave aficionados it's Joerg Klingenfuss's 
comprehensive collection in print and on CDs. Joerg has been a leader 
in shortwave publications for decades, covering both broadcasting and 
utilities; his latest issues are excellent examples of his continuing 
effort to offer professional and comprehensive volumes. 2016 
Shortwave Frequency Guide ... This 20th print edition should provide 
ample evidence to refute the 'shortwave is dead' myth. Last year's 
volume had 360 pages. This year's volume? Still 360 pages. While it 
is true that the broadcasters are slowly but surely emigrating from 
the HF spectrum, utility stations are actually on the rise. As might 
be expected with the dwindling broadcast users of the HF spectrum, 
there are only about half the number of frequencies in this list as 
there were for utilities. For convenience to the listener, 
Klingenfuss addends the frequency list with a cross reference of 
stations listed alphabetically by country. Clandestine stations have 
a list of their own, with such notables as Radio Libertad, Voice of 
Freedom, Sound of Hope, Voice of the People and many, many more. -
