We are probably damned to fight agains QRN and QRM. Recently I had opportunity to buy an external DSP device. I wonder what the experience of DSP users are. Certainly it is great to have a very narrow non-ringing filter. I mean rather use of noise-reduction techniques. Do they really provide a possibility of making very weak signals (normal CW) more readable? Or is it only a toy and I had better to rely on my well-trained ear? Petr, OK1FIG
