Anyway, more than 900 fascinating new digital data decoder screenshots will be published on our 2026 Super Frequency List on CD, again covering really unique MIAM messages as well. See our hotfrequencies webpage for dozens of samples! These Media Independent Aircraft Messages - via HFDL! - are often really looooooooong, with up to several hundred XML format elements ...
The printed Supplement, with many new frequencies and stations monitored throughout 2025, will be attached free to all copies of the 2025/2026 Guide to Utility Radio Stations sold after 1 January 2026. Those customers that did acquire the 2025/2026 Guide to Utility Radio Stations before that date may download the pertinent PDF file free from our website, after 1 January 2026.
The incessantly updated product Digital Data Decoder Screenshots on USB Stick now covers more than 28,000 (twenty-eight 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 !
