Hi
LF,
You may have seen
an image of a NAVTEX signal on my 500KHz grabber at about 506KHz. The original
of this image is at 518KHz. The receiver for this grabber is a Softrock Lite
455KHz module modified for 500KHz.
I have attempted
to notch the signal using a simple series or parallel filter but only succeeded
in seriously degrading the whole band possibly due to the bandwidth of the
filter??
Is there some
simple narrow notch filter which I could use to remove the offending
signal.
