Re: [Discuss-gnuradio] AUTOMATIC START AND STOP FILE RECORDING

[Kevin McQuiggin]

Why not just record at the three stations continuously with accurate time 
stamps going into the files?  Then you can line up the three recordings easily 
using the time stamp values.  When the recordings start and stop won't matter.
