Ignacy Maybe your rig has a problem. NR does not affect the signal strength at all. It does however reduce the audio level, depending on how aggressive the setting is.

NTCH is also outside the AGC loop. I also suggest the following refinements to NTCH: - faster or adjustable notch time in automatic mode. Now it takes a second and does not work if the carrier is slowly drifting. - adjustable width in manual mode; e.g., can be adjusted by buttons 1-4 For instance 1=20Hz, 2=50 Hz, 3=..... The current one is 250HZ and is wide. It may be the same code to put both NR and NTCH into the AGC loop. Would anyone agree that these features will be worthwhile? For me several times NR 3-3 made a difference between a copy and no copy for weak signals but the volume was too low.
