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.
