After a long SDR hiatus I started to put my Perseus back into action yesterday. This time around I have it in a dedicated Win7 partition that can only access 50 GB. This is a deliberate restriction to force me to be more selective in what I record and how long I keep it for. I realize that I must form a new and more meaningful relationship with my <Delete> key.

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. -- -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296, 10GHz & Light
