The DSP-100 Digital Signal Processor adds high quality digital signal processing technology to the TS-850S. By converting the signal into a digital waveform it is possible to tailor the audio passband of the transceiver.
The DSP-100 also provides increased suppression of the unwanted sideband during SSB operation. It increases carrier suppression, provides and inproved CW waveform, and allows operator preference of rise and decay times of CW signals. Four different low pass and high pass filter settings provide maximum signal intelligence with minimum bandwidth.
The DSP-100 processes received signals at the detector level, providing a digitally processed signal that sounds clearer and is easier to copy.
NOTA : I used this external digital signal processor for 7 years (1997 to 2004).
