I'm curious to hear how other DX'ers tackle "data management" when it
comes to the use of I/Q recordings from SDR receivers. My SDR-IQ allows me
to record 192 KHz of bandwidth, and using HDSDR software, I've started
recording TOH periods overnight. I record about four minutes per hour,
starting at local sunset and continuing through sunrise.
This provides a total of 19 MW channels to be reviewed per hour, Recording
for 4 minutes over a ten hour period, leaves me with 760 minutes of data to
be reviewed daily. Some channels are nearly impossible to find new ones on,
so these can be reviewed quickly, checking only for unusual conditions. But
it's still a massive amount of data.
Since starting this just a few days ago, I've already deleted days of
recordings, unchecked, simply because there is no practical way to review
it all. Perseus owners would have an even bigger issue, due to the much
wider bandwidth that can be recorded. The entire AM band for instance!
What strategies have other DX'ers found successful for managing the data?
I've considered recording just the sunrise/sunset periods, or waiting for a
night with unusual conditions to record TOH ID periods only, or even simply
recording for a week in mid-winter, then taking my sweet time to review
them during the summer.
