05:00:00 : Started setup.
         : Power equalization and phasing done.
    
05:25:27 : Started scan on 1154-350 for ~ 0.760566 min.
05:33:09 : Started scan on 1154-350 for ~ 6.17401 min.
05:39:32 : Started scan on 1154-350 for ~ 0.850045 min.
         : Due RFI Phasing was not happening.

Due to satellite RFI + phasing not working user\'s  time has lost.
