Gentlemen, Archie Tremmel IS THE MAN!!!
thanx BOAC, Centaur, and others. Your views were really enlightening indeed. I shall observe how Maxing the Gain would work out in hunting down cells and then increasing gain progressively to scan for the worst part of the cell.
and yes, google has a LOT of hits for the name Archie Tremmel, (thankfully all of them relate to the Wx Radar Guy himself!!)
anyone else would be still encouraged to give in their pointers collected by them over the years. Who knows, there might be PPrune's very OWN "Archie" emerging!!
thanx again.
cheers.
