Excellent long-distance propagation in 2025-2026 and far beyond.

 

Dear friends,

 

says NOAA's Space Weather Prediction Center on 9 August

2024 at www.swpc.noaa.gov : "Solar Cycle 25 likely reached

the highest sunspot number yet - a value of at least 299.

The SWPC non-official, estimated daily sunspot number for

August 8th was 337, a value not observed since March

2001." By consequence, we'll see good to excellent

high-frequency (HF) long-distance propagation conditions

throughout 2025-2026 and far beyond.

 

More than 800 Kiwi-SDRs are now available at

www.kiwisdr.com , allowing easy global monitoring and

decoding of professional HF digital data stations. Hundreds

of pertinent screenshots will be published in our brandnew

2025 editions. See dozens of samples on our hotfrequencies

website!

 

We're now working on our new products

 

- 2025/2026 Guide to Utility Radio Stations

- 2025 Shortwave Frequency Guide

- 2025 Super Frequency List on CD

- 2025 Frequency Database for the Perseus SDR

 

to be published on 10 December 2024.

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 2024.

 

The continuously updated product Digital Data Decoder

Screenshots on USB Stick now covers more than 27,000

(twenty seven 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!

 

Shortwave is dead? Well, we've been told so ... for 57+

years. More than 1,000 (one thousand!) selected new digital

data decoder screenshots will be published on our 2025

Super Frequency List on CD ;-))
