So I don't use that anymore.\r\nHDSDR is a *lot* better, although it seems to be a dead horse, because it's not\r\ndeveloped further. FM-deemphasis is bitterly missing. I asked the author to\r\ninclude it, but nothin happened.\r\n\r\n    Do you see that high cpu load on some specific band/demod ?\r\n\r\n\r\nIt varies with bandwidth setting (of course)\r\nSR                      -aa-            -bb--\r\n12000           50%             73%\r\n192000          62%             80%\r\n\r\n-aa- is the other version\r\n-bb- is your version\r\n"}}
