Re: [IRCA] SDR Recordings

["Chris Black" <n1cp@xxxxxxxxxxx>]

At the home QTH I usually go with 2 min before TOH and 2 after for the band 
unless a compelling reason to change like needing a bottom of the hour for a 
particular frequency. Of course DXpedition recording is a different animal; 
more is always better.

Stop and think what you're getting yourself into.

118 frequencies (530, 540, 550... 1700 kHz) * 10 minutes (5 minutes before 
the hour and 5 minutes after the hour) * 24 = 28,320 minutes.
  28320 / 60 (minutes in 1 hour) = 472 hours needed to listen to 1 day of 
TOH recordings.

How about only 1 TOH recording?
  118 frequencies * 10 minutes = 1,180 minutes.
  1180 / 60 = 19.67 hours needed to listen.

How about only record 2 minutes before the TOH and 2 minutes after.
  118 frequencies * 4 minutes * 24 = 11,328 minutes.
  11328 / 60 = 188.8 hours

How about only 1 TOH 4 minute recording?
  118 frequencies * 4 minutes = 472 minutes
  472 / 60 = 7.867 hours needed to listen.

Hope you have plenty of time available.
