not too bad overall  Time owned: more than 12 months
I have had this dsp filter since 1995 and it is still serving well. The unit looks sturdy made. It is very well protected in the audio input and in the power input. Notch filter eliminates completetely cw and tuning leaving the speech unaltered. Noise reduction does not change the speech too much. Also Data and CW is cleaned well with the noise reducer.

A couple of settings are however done internally moving jumpers. The unit does not have a high impedance output, so that an audio transformer may be added.
