Kevin,
In 99.999% of cases where a database reset resolves erroneous behavior
of PowerSDR, it is due to invalid data (the database is inconsistent)
resulting from PowerSDR shutting down improperly, either due to a forced
shut down, or the PC going into a suspend or hibernation state where the
in-memory data is not properly written to disk. I seriously doubt that
the database is actually corrupted, because PowerSDR has logic to ensure
that the XML data structures are correct and if they are not, it will
perform an automatic recovery and use the "last known good" database
from the three deep generational backup that is performed when PowerSDR
is started.
Check your power management settings and makesure that you are using the
high performance settings

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.
