Re: [IRCA] Laptop computer requirements for an SDR or similar receiver.
Mike -
You wouldn't want to do an overnight recording session. 8 hours of Perseus recording would take you almost 900 hours to listen to. Until I'm retired and tired of shuffleboard and bridge, I'll never come close to having that much time available.
Better to pick your times: a few minutes over the top of the hour and half hour for all the channels and anything else as-needed.
Doing that, I easily get 3 or 4 nights onto a 250 GB internal drive. After that, it all gets transferred to the 1 TB or 2 TB drives that hold stuff for later analysis.
