[IRCA] Reviewing SDR DX

[Les Rayburn <les@xxxxxxxxxxxxxxxx>]

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.
