Why MeteoFax32 does not use the sound card of the computer to demodulate the signal?

The MeteoFax32 modem was designed to obtain a decoding of high efficiency even under bad reception conditions. This modem provides an analog filtering (see analog filter) and a digital signal processing by a processor which executes a program (firmware) that will process the signal and ensure communication with the software. This provides optimal performance both on tranceiver or pocket radio. No software can provide satisfactory results if the signal that is provided is not of sufficient quality such as in the case of a basic demodulation by the sound card of the computer. This type of demodulation does not have the required sensitivity level when you move away from areas near the transmitters as is the case for example during an Atlantic crossing in the area of trade winds. Only an external modem specialy designed for this type of signals provides global coverage at sea See: MeteoFax32 modem
