For weak CW signals try NR= mF5-3 with IF BW= 700-1000 Hz and APF on. The mF#-# settings mix unprocessed signal with the NR processed results. the second # sets how much. The wider IF bandwidth lets the NR work optimally on random, uncorrelated noise while the APF pops the desired signal out of the muddle the NR makes. Tune carefully using the FINE tuning rate, the APF is very narrow. There can be no other stronger signals in the IF passband. I haven't had much success using the DSP NB. The IF NB works well on pulse noise and some powerline noise but if there is a very strong signal nearby it will create some nasty artifacts. 73, Brian, K0DTJ KC6CNN wrote ..... Is there any information or help in finding a good setting for these.
