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!
We're now working on our new products
- 2017/2018 Guide to Utility Radio Stations
- 2017 Shortwave Frequency Guide
- 2017 Super Frequency List on CD
- 2017 Frequency Database for the Perseus LF-HF Software-Defined
to be published on 10 December 2016.

If you are able to supply additional new frequencies and stations,
your cooperation would be highly appreciated. Please let us have your
data by 22 October 2016.
The continuously updated product Digital Data Decoder Screenshots on
USB Stick is highly successful and now covers more than 12,300
(twelve thousand three hundred!) screenshots from 1997 to today. Feed
your PC or Tablet with this data, and the "slide show" will keep you
busy for a few days - or weeks!

Frank Ravenswood K2NCC, United States of America - 6 March 2016: "One
thing I have a lot of in this house, is printed material. Shelves and
boxes of knowledge I wish I could better retain, but enjoy
nonetheless along the way. Most eventually get traded, donated, sold,
but some I just never get rid of. Reference books mostly, many with
information not found online. Yeah, it was a surprise to me too,
everything isn´t on the Web! The Klingenfuss guides are a great
Radio User, United Kingdom - March 2016: "2016 Shortwave Frequency
Guide ... 2016 Super Frequency List on CD ... Over the past 47 years,
Klingenfuss Publications has built a reputation for producing superb
frequency guides and reference books that are of interest to both
professional and hobby radio enthusiasts. Whether your interest lies
in aeronautical, maritime or military communications, news agencies,
non-governmental organisations, standard frequency and time signal
stations or weather broadcasts, these Klingenfuss publications are
likely to be very useful reference sources. Without doubt, the
combination of these two items should meet the needs of most devotees
for the low frequency, medium frequency and shortwave bands."

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 radioreference.com
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. -

Alfredo Gallerati IK7JGI in Associazione Radioamatori Italiani's
Radio Rivista, Italy - December 2015: "2016 Shortwave Frequency Guide
... importante guida operativa, una guida che consiglio di tenere
accanto al nostro ricevitore per disporre di un database aggiornato
da sfogliare con pochi 'click' delle dita, magari durante la nostra
caccia al dx. A Klingenfuss ... dobbiamo un ringraziamento perchè da
20 anni non ci fa mancare questa panoramica aggiornata di frequenze
mondiali BC da tutto il mondo in circa 400 pagine. La stessa SWFG
esce anche in versione CD con il titolo 2016 Super Frequency List
aggiornatissima e di facile gestione da computer. Attraverso una
utility interna offre la possibilità di una comoda ricerca di
stazioni e frequenze aggiornate, grazie all'impostazione dei
parametri di lingua e Paese. Per gli amanti del radioascolto utility
è targata la famosa 2015/2016 Guide to Utility Radio Stations che,
ogni due anni in 550 pagine, offre una panoramica aggiornata del
mondo delle Utility."
