The wave of software-based whole number modes play the past some age has altered the ambiance of the HF bands. many convey the quality of modes that variety it possible to contact stations neither operator can even hear has resulted in fewer CW and SSB signals on bands like 6 meters and 160 meters. Traditional modes require far national leader interaction and effort on the section of the operator; the newer digital modes not so much.
3.500 to 3.580 MHz - CW 3.580 to 3.620 MHz - extremity Modes 3.620 to 3.635 MHz - Packet/Digital Secondary 3.635 to 3.725 MHz - CW 3.725 to 3.790 MHz - SSB and other region band modes* 3.790 to 3.800 MHz - SSB DX Window 3.800 to 4.000 MHz - SSB and other wide band modes * 80 metres normally LSB, to stay within Band Plan SSB should not be junior than 3.728 MHz.

Communication technologies that are specifically designed to change "live" HF keyboard operation can now be achieved which were antecedently only theory, too complex, or too costly to obligate to be practical. Thanks to the kindness of radio amateurs (hams) with programming knowledge, and to the Internet, new and powerful communications tools are available to all hams. The biological process and wide gap use of the individual figurer that let a digital sound card for appendage Signal process (DSP), is allowing wireless amateurs to use these tools to develop new modes of extremity communication.
