Improving selectivity for close CW signals?
As a KiwiSDR user (not an operator), I've found that when I select CW mode and drag the sides of the bandwidth bar as close as possible, it is still often difficult to hear a signal clearly if another CW signal is close by.
Are there other user settings or commands within KiwiSDR to help with this? Or would my main option be audio post-processing with, say, an audio filter in-line with my headphones, or outputting to a program like Spectrum Lab, etc?
Thanks for any suggestions,
