Hi Gary,
rrr - the audio filter is implemented in SpecLab, but it's been there 
since quite a long time -  I just never used it to listen to morse code 
with such a low bandwidth myself. It is actually the "FFT-based filter", 
which can also be used with real signals (i.e. not complex) from the 
soundcard.
The configuration for the SDR-IQ is in the file "SDR-IQ_narrow_RX.usr", 
which will be included in the next release. But with some dozen 
mouseclicks, that configuration can be created for the soundcard input, too.

Cheers,
  Wolf .
