[TenTec] [Norton AntiSpam] Re: Corsair vs. Orion (weak signal)

[Robert & Linda McGraw K4TAX]

The original post indicated that the IMD was zero beat with the incoming 
signal.  Makes me wonder what part of zero isn't understood.  Either it is 
zero beat producing a sum signal (Fa + Fb) which is not heard and a 
difference signal (Fa - Fb) which is zero, again not heard.  Has nothing to 
do with what frequency one prefers to listen to CW.  If one understands what 
zero beat means then I need not explain further.
