Says Hugh Stegman NV6H, Utility Planet Editor, in The Spectrum Monitor – October 2021: “Kiwi-SDR´s underlying technology is the
biggest thing to happen to this hobby in a very long time. It´s never going to replace DXing from home, but it does supplement it with very powerful tools. It´s hard not to be excited …” More than 600 free receivers worldwide are currently linked e.g. on www.kiwisdr.com
Our article “Internet-controlled SDRs”, focusing on the reception of fascinating HF utility radio stations, is available at
HF is dead! Really? We’ve been told so … for 54 years ;-))) Anyway, more than 900 new digital data decoder screenshots will be published on our 2022 Super Frequency List on CD … To be continued!
The incessantly updated product Digital Data Decoder Screenshots on USB Stick now covers more than 22,400 (twenty-two thousand four 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!
