I am interested in Non-Directional Beacon (NDB) DX'ing and I use a Winradio Excalibur SDR, which enables me to get the CW bandwidth down to 10Hz or less.
My normal listening bandwith is in fact 10Hz.
I have been listening to NDBs on the KiwiSDR but have been unable to get the minimum CW bandwidth down below about 50Hz
Is this the minimum that the current software allows?
If so can it please be altered to enable at least a 10Hz bandwidth to be used?
