Hi Andy,

I've nicked some of the palette tables from the Speclab folder - saves reinventing wheels. Are there any copyright / restrictions on their use : The one above is Horne's 'Gram' Palette; still one of my favourites

Certainly no restrictions, since I did not copy Horne's palette, instead I "painted" my own (if that's the correct phrase). Same applies to the other palettes - my personal favourite for many applications is the "sunrise" palette which iirc was "painted" in Italy..

Cheers,
  Wolf.

PS the "Zoom FFT" descibes what SL does to create very long FFTs, too. There is nothing special about it. Any SDR with a digital downsampler (as the AD6620 in SDR-IQ) uses the same principle as the "Zoom FFTs" pre-processor in the time domain. It's only important to get the signs for the sin+cos output of the mixer (multiplier) right, to avoid ending up in the wrong sideband .. still thinking what the 'reference' for my own treatment of I+Q recordings was. Possible SpectraVue, which came along as the original software for the SDR-IQ.
