The computer I use with my SDR-1000 recently took either a ligtning hit or a power surge, such that the motherboard had to be replaced. I've since rebuilt this machine with a new motherboard, using the original disks, memory, cpu, Delta44, etc. It has a fresh install of WinXP Home SP2.
I've done a fresh install and calibration of PowerSDR 1.6.2 and also have the K6JCA console (July 29 version, I think). All seems to be well except for the fact that the received audio is accompanied by an annoying "crackle" which is very unpleasant to listen to and was not evident prior to this incident. The voice or CW audio itself seems OK - subjectively, the crackle seems to be superimposed on otherwise good audio. I made a post-processed wav recording of a CW signal. On playback via the computer's on-board soundcard (not the Delta44) the audio sounded clean - no nastiness present. I haven't tried a recording/playback of pre-processed signal yet. Buffer sizes are the initial defaults for the Delta 44 and PowerSDR. I'm wondering if I missed some config setup option or if the Delta44 card is damaged also? I plan on trying to move it to a different slot on the motherboard to see if anything changes. Any ideas appreciated.
