Hi,
FW: uC 05.41 + d1/2 2.76 + FL1.15 Switching to manual notch in both modes. Notch working on CW as it should, notch switches off at 100hz en 50 Hz BW. (No serious problem :-) ) Notch working on SSB and data as it should, also at lowest BW, which is 150Hz for SSB. 73 Arie PA3A Op 22-10-2012 8:24, Dan Sherwood schreef: > All, > > I purchased 200 Hz 5-pole filters for my K3.
