The 1 kHz filter is a decent roofing filter for general CW use. It is wide enough that you can hear someone off frequency but narrow enough to attenuate a big signal close by.
The 500Hz is pretty narrow and you might not hear someone calling off frequency. Sometimes that is a good thing, as in very crowded contest conditions. k4ia Craig "Buck" Fredericksburg, Virginia K3 #101 **************Ideas to please picky eaters. Watch video on AOL Living.
