Best advice I've got so far was an off-list reply that said:

Russ's is a close second. SDR's may simply be too much of a good thing.
I remember a few years ago when I used "Total Recorder" to record TOH
ID's on a single channel. I reviewed these during my half hour long
commute to work in the morning, and again while driving home in the
evening. Even then, I often couldn't get through an entire night's
recordings.
SDR's have just magnified the problem. Plus my SDR-IQ is a great, but
not quite the performer that my old Drake R8-B was. And it's difficult
to use an SDR with a phaser, because of the small latency issues. It
makes it difficult to adjust for the best null.

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.
