Dear Andy & Group,
	With a 1Hz Bandwidth, isn't it rather difficult to find the signals 
in the first place? How do you tell if what you are receiving is a 
signal or not? It seems to me that some radically different 
operating procedures will have to be devised to exploit extreme 
narrow band techniques such as these!
