Hello Leif, thank you very much for your answer and suggestions. At the moment i'm using my last assembled 3 GHZ PC with 2 GHZ of RAM. I wish one day to hear you on 2m cw eme.

The below is what I wrote on the Linrad development page. At the moment there is no more info available. Start with a small vertical size (limit the number of lines) and use a modest size for the fft2 transforms. That will work on most computers. Use F1 to get info. Edit par_userint (or delete it) to change screen setup. For real usage with a large screen and large fft2 transforms you will need a modern computer with a lot of memory because otherwise Watzo will have its data in the swap file on the hard disk. 73 Leif / SM5BSZ The watzo program uses a lot of memory if a large vertical screen size is selected in combination with large FFT2 transforms because the full averaged power spectrum is kept for twice as many lines as those displayed on screen. With a transform size of 131072 each waterfall line will allocate 1 megabyte for a single channel system and 5 megabytes for a two-channel system. It is possible to limit the number of lines to avoid having data swapped to the hard disk. Watzo uses temporary files that may use up to 16 gigabytes of hard disk space to store data over long periods of time. Scrolling back in time becomes very slow if the main data is swapped to disk. By using the MMX implementation for FFT2 one can save a factor of two in the scratch file size and thereby get a somewhat faster scrolling back in time. ############################################################# This message is sent to you because you are subscribed to the mailing list <linrad@antennspecialisten.se>.
