Let's see......the Corsair II was reviewed in 1986 and sold new for $350.00. So I guess what we're saying is that receiver technology/performance has not changed much if any in some 20 years. As to whistles and bells......radios are loaded today with them and the 756 Pro III is an example. But even with many other models, all the whistles and bells, dual receivers, 1000's of memories, dual VFO's and band scanners, the bottom line is if one can't here 'em they can't work 'em. Sherwood Engineering has the Corsair II listed in the top 15 with regard to receiver performance. I think Don's comments are a testament to the fact our objective to radio performance has vastly changed. But as hams, we are driven to have the latest and greatest regardless.
