jdow jdow at earthlink.netHe sent me two frequencies in private email. These were in the FM broadcast band (in the US). He probably needs to notch them out in order to get adequate response. As for wanting narrow bandwidth - I am not quite sure why he thinks that is a benefit. I use a large FFT (about 10 Hz per bin) and use the zoom control to see fine detail. (Different FFT settings suite different uses. This one seems to be a good compromise with my two needs. I'm too lazy to change it.) {^_^} On 2013/10/22 02:08, Sylvain Munaut wrote: >> Effective filtering must occur between antenna and receiver.
