Second number is global deviation in hertzs, i.e. maximal deviation from current frequency. The first number is local deviation in hertzs, i.e. The numbers to the left of the AFC button determines the limits of AFC. The " AFC" button (auto frequency control) adjusts the long red lines (working frequencies) to the closest peak frequencies. When squelch is switched on, the horizontal red line shows the squelch threshold in spectrogram window. The number to the left of the "SQL" button determines the squelch threshold. Logarithmic scale is more convenient usually, but it needs more computer resources.
Analogously, the " Setup->View->Logarithmic oscillogram scale" option or Ctrl-Z hotkey switch oscillogram scale.
The " Setup->View->Logarithmic spectrogram scale" option or Alt-Z hotkey switch spectrogram window between linear or logarithmic scale. This window can be hide by the " Setup->View->Show oscillogram window" option The bottom window shows an oscillogram of the decoded signal.
To change the center frequency, click on the desired frequency (probably between the peaks). In FAX mode these lines show "black" and "white" frequencies. The long vertical red lines in this window show the working frequencies of the decoder filters. Ruler under this window shows frequencies of sound spectrum. In the top window the current spectrum of a signal (blue line) and a peak detector of spectral components (green line) are shown. The working area of the program is divided into several windows, the sizes of which can be changed by the user by dragging the borders. No additional hardware is required you need only a receiver and computer with a sound card.
Software also can automatically save NOAA Weather Radio SAME voice messages (NWR SAME) and them digital headers. It can decode GMDSS DSC (HF and VHF) messages. Transmitted in RTTY, NAVTEX, PACTOR-1 FEC and HF-FAX (WEFAX) modes on longwave and shortwave bands. Simple software to handle devices connected to LPT portĪ program to receive weather reports, navigational warnings and weather charts A tool for monitoring popular web-cluster service from OH9W/OH2AQ Radio Club
Only the new Klingenfuss products for 2022 take this fascinating new trend into full consideration - now! We - who else? - provide hundreds of brandnew HF e-mail frequencies and screenshots.Weather messages decoder - RTTY, NAVTEX, PACTOR-1 FEC, WEFAX (HF-FAX), NWR SAME softwareĬluster monitor. Interestingly enough, the immense potential of HF e-mail has not been monitored - let alone realized! - by any other author and publisher so far. With 52 years of experience in the field of worldwide radiocommunication via HF, we predicted already in 2000 that HF e-mail will continue to spread rapidly and will soon develop into the major application of modern digital HF techniques that we have marketed - and used! - for years. The Utility Radio Guide is the ideal companion to the new 2022 Shortwave Frequency Guide for the "special" stations on shortwave! Aeronautical and Maritime Mobile Service frequency allocation plans. Name and traffic abbreviations and signals. Worldwide NAVTEX schedules of navigational and meteorological warnings on 424, 428.6, 486, 490, and 518 kHz. Plus: Meteorological radiofax/radiotelex stations. Another 300+ brandnew frequencies monitored in 2021 can be downloaded here! A handy index lists 1,600 stations in 250 countries for rapid access.
Comprises 9,123 frequencies monitored during 2020 with call sign, station name, ITU country symbol, type(s) of modulation and corresponding return frequency, or times of reception and details. Again includes more than 230 fascinating new screenshots from the world leader in advanced digital data transmission and teleprinter systems monitoring and decoding.
The 2021/2022 Guide to Utility Radio Stations has 550 pages.Ĭovers the complete shortwave (HF) range from 3 to 30 MHz, plus the adjacent frequency bands from 0 to 150 kHz and from 1.6 to 3 MHz. Here are the really fascinating radio services on shortwave: aero, diplo, maritime, meteo, military, police, press, and telecom. Only this guidebook gives you hundreds of brandnew frequencies and screenshots! New chapters cover disaster communications and terrorist networks as well. Today, worldwide HF e-mail networks are the hottest talk in town for aid agencies, business companies, coastal stations, non-governmental organizations, the International Red Cross, the United Nations, and terrorist organizations.
