A very good one Neal, if you do not mind I'd like to add to also advise Kevin to double check the memory configuration settings in the BIOS. I remember having an occasional corruption problem usually followed by a BSOD for which I could not track down the cause until I found out the memory configuration settings in the BIOS were not 100% correct (w hen in doubt select the 'auto' setting).

I doubt strongly that reinstalling will help (although its easy to do so feel free). If you run a disk check and it comes up clean, its not disk so either the motherboard is wacko (and it would be evident as you would have things falling apart all over the place) or the memory has a back stick and when/if PSDR stores data there it gets corrupted. 73 Neal Campbell Owner Abroham Neal LLC Work: +1 540 645 5394 Mobile: +1 540 645 8171 On Tue, Apr 30, 2013 at 11:10 AM, < ke...@3950.net > wrote: On 4/30/2013 5:22 AM, on4...@telenet.be wrote: <blockquote> Kevin, I would either suspect the anti-virus program or potentially also a faulty hard drive (or at least may be some bad sectors on the drive). The latter can be checked through a windows disk check utility, the former I would exclude the database directory from the real-time scanning or if that would prove to be too difficult to do, disable the anti virus all together (just for the sake of the test). Please also check all drivers are up to date. Guy Thanks, Guy. Will check the hard drive (though it is brand new) and the drivers. I don't think it's the anti-virus, as it is Avast and I know several other Flexers who use it without problems. Maybe a fresh install is called for, too. Still working on it, Kevin. <blockquote> ----- Oorspronkelijk e-mail ----- Van: ke...@3950.net Aan: flexradio@flex-radio.biz Verzonden: Maandag 29 april 2013 17:22:31 Onderwerp: [Flexradio] Constant database corruption I recently installed a Flex 5000 at a friend's station -- PowerSDR 2.5.3, Windows 7, i5 motherboard, 16 GB, TI firewire chipset. The rig works beautifully when started up, but after a day or two, sometimes less, PowerSDR crashes (it doesn't stop responding, but the radio loses its ability to transmit or receive). Before it crashes, odd things happen: 1. Receive bandwidths get reset to odd values, for example 3.4 kHz gets set to 100 Hz or sometimes plus and minus 2 kHz. No pattern, just seems crazy. 2. Received signals get an odd and continuous "buzz modulation" -- this only happened once. 3. Transmit bandwidth settings get changed or become unadjustable. Several other things change too, but there's really no consistent pattern -- just crazy values seem to creep into many settings. RF ingress isn't the culprit, as refraining from transmitting doesn't help. A database import clears the problem -- for a day or two, then it starts all over again. Any ideas? Thanks, Kevin, WB4AIO. </blockquote> ______________________________ _________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/ mailman/listinfo/flexradio_ flex-radio.biz Archives: http://www.mail-archive.com/ flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/ </blockquote> _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
