Joe Taylor K1JT przedstawił nowy protokół FT4 – jest to FT8 zmodyfikowany specjalnie do zawodów.
Poniżej oryginalna informacja – chwilowo w języku angielskim. Dalej interesujące odnośniki o FT4.
Colleagues,
Yesterday a new digital mode for digital contesting has been announced by Joe Taylor, K1JT, Steve Franke, K9AN, and Bill Somerville, G4WJS – called FT4.
FT4 is a special-purpose mode designed for rapid-fire contest QSOs. Like FT8 the mode is not useful for more extensive conversations. FT4 has a bandwidth of abt. 90 Hz.
The following default dial frequencies are suggested for FT4: 3.595, 7.090, 10.140, 14.140, 18.104, 21.140, 24.919, 28.180, 50.318, 144.170 MHz.
Joe, Steve and Bill will welcome any feedback that could lead to better frequency choices, they are writing.
You will find more information abt. FT4 at http://physics.princeton.edu/pulsar/k1jt/FT4_Protocol.pdf
The choice of frequencies should be discussed very intensivly, especially those for the 40 and 20 meter band. Because of this an international group of band planners stays in touch. The R1 HF committee is part of this.
