Thank you for the post. I was experimenting with WWVB reception also and will have to try this for NDB DX reception. What advantage does the Goertzel filter have as opposed to just using a narrow band FIR? I see you still have to specify the 250 Hz offset in the filter, so I assume it doesn't help with detection if you drift off frequency.
