[TenTec] Corsair vs. Orion (weak signal)

[Robert & Linda McGraw K4TAX]

While the technical measurements of the various receivers do seem to show 
certain ones to be better than others, what ever "better" implies, the 
reports of being able to hear signals on one receiver and not another leaves 
out one important factor.  The human brain coupled with the ears do allow 
one to hear signals that are typically 6 dB to 10 dB below or down in the 
noise.  Also the human hearing has and adaptive feature that allows the 
brain to disallow, on a short term basis, any unwanted signals received by 
the ears.

In most cases it is observed that the skill of the operator exceeds or 
greatly impacts the end performance results, regardless of the technical 
merits of the equipment.  These factors do not seem to be "weighted" with 
regard to receiver performance.  A factor that I personally observe has to 
do with the quality of the audio chain, the character of the noise being 
produced within the receiver and the artifacts of any digital processing.
