I've just received a mail from Joerg, owner of the publishing company, Klingenfuss Publications, located in Tuebingen, Baden-Wurttermberg, Germany.
He wrote that recently, they'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
their 2017 editions - see some samples on their
NOAA sunspot numbers now are between 0
and 100, with the solar cycle minimum expected for 2019.
However, they still
experience good propagation conditions up to around 21 MHz: on 13 October they
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, as they think.
They're now working on our new products

Frank Ravenswood K2NCC, the US - 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 example."

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,

Spectrum Monitor, the US - February 2016:
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
