New Klingenfuss products for 2027
Dear friends,
after an exceptionally strong solar cycle peak, propagation
conditions are still very good, allowing excellent reception
of e.g. HFDL stations on 21 MHz - see our hotfrequencies
webpage updated daily. What's more, we've monitored
hundreds of new military frequencies ...
We're now working on our new products
- 2027/2028 Guide to Utility Radio Stations
- 2027 Shortwave Frequency Guide
- 2027 Super Frequency List on CD
- 2027 Frequency Database for the Perseus SDR
to be published on 10 December 2026.
Full-resolution title page graphics can be found at

www.klingenfuss.org/s_2027.pdf
Just for the record, these are not stupid compilations by
"Artificial Intelligence", but the results of daily (and
"nightly" ...) real radio monitoring and decoding.
If you are able to supply additional new frequencies and
stations, your cooperation would be highly appreciated.
Please let us have your data by 20 October 2026.
The continuously updated product Digital Data Decoder
Screenshots on USB Stick now covers more than 30,000
(thirty thousand!) 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!
More than 800 (eight hundred!) selected new digital data
decoder screenshots will be published on our 2027 Super
Frequency List on CD.
