With our technology you are in the position to delete these interferences either totally or at least to minimize significantly. The result is a much better signal to noise ratio (S/N) to enable a readability without any strain.
Our product Speech-Extractor LINGUA combines the noise suppression algorithm in the core of a well considered hardware which is excellently harmonized for the use in amateur radio- or SWL-applications.
The picture shows a disturbed speech-signal in the 40 m-band. In the first half LINGUA is deactivated, thereafter activated. You can recognize the noise tending to zero. Just the speech (as transmitted) and not the unwanted noise reaches the AF-output of LINGUA and can be heard in a normal station speaker and / or headphone.
Interfered speech-signal without and with activated LINGUA (40m).
