Hi Laurence and all,

You asked:

 Is it better to have a longer FFT input size and smaller decimate or 
say smaller input size and larger decimate :-) ?
<

It doesn't matter for this application. Important is only the resulting 
FFT bin width, which is displayed on the 'FFT Settings' panel.
Longer FFT and less decimation has the advantage of covering a larger 
bandwidth (to pan around), but since we know Uwe's frequency quite 
accurately that's not so important. On PCs with less than a gagabyte of 
RAM, or if many other programs need to run simultaneously, keep the FFT 
size below 512k .
