1. Introduction.
The NEDSP1061 module features is a fully integral solution for noise reduction for the
FT-817.
2. Operation.
All functions of the NEDSP1061 are controlled by a single button.
•Single press turns the noise cancellation on/off.
•Holding down the button changes the DSP filter level.
The mode of operation is indicated both by a flashing LED and a beep.
The LED is illuminated red when the noise cancellation is off.
When the noise cancellation level is changed the LED will flash green to indicate which
level has been selected.
Simultaneously the DSP will beep to give audible indication of DSP level. This allows the
operator to change the DSP level without having to look at the LED to see which level has
been selected.
A short beep is emitted to acknowledge a button press.
The module will store the current DSP level, and will return to this level when the FT-817
is switched on.
