My SDR-1000 (an older rev box with RFE, no PA or tuner, parallel port
interface) receives fine for the first couple of minutes then goes deaf.
Cycling the DC power restores the receiver for another couple minutes, then
it dies again. Just before it craps out, the baseline as viewed on the
spectral display raises from -130 to about -70 a couple times along with an
increase in the white noise, then drops to -140. All frequencies appear to
be dead. Restarting the software has no effect, so it's a hardware issue.
I have yet to open the enclosure and get the scope out, just wondering if
anyone has seen this, or has a suggestion on where to start looking.

When I had problems like that, it related to problems with the sound
card setup. In the most extreme case, I had configured the wrong card.
If you're receiving at all, that's not your problem.
However, to take another possibility I've seen, if you have your SDR
sound card set as any of the Windows default sound devices, some very
strange results can happen. This can happen in ways mysterious.
Check all your sound card settings for the SDR and any nonSDR cards.
Check that you don't have bad defaults and check that you have things
like reverb turned off, the correct mixers and microphone et. al.
settings set on or off.
