Hi LF,

My thanks to Wolf - DL4YHF, Graham - G0NBD & John - GM4SLV for reports.

Wolf, is that the filter you spoke of in the latest SpecLab ??

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 .
