Problem:
The volume of the FT-817 can be increased up to a point - where it then starts to fall.
Cause:
Input level to the NEDSP1061 is too high and causing the DSP input circuit to clamp.
Reduce the signal input level using P2.
Problem:
Increasing the volume to the FT-817 creates distortion.
Cause:
Output level from the NEDSP1061 is over driving the FT-817 power amplifier.
Reduce the output level using P1.
Note:
When listening high noise/signal broadcasts it is possible for the DSP to create an
effect that resembles slight clipping. Always check clipping problems with a good quality
clean audio signal, such as an FM talk station.
