[SFDXA] Sherwood RX performance Comparison

[Kai Siwiak]

Hi Norm,
That is indeed an interesting listing, but you need the "method of measurement" 
before the numbers have meaning, especially across different products. Ask any 
"Standards" or "Specifications" guy ... if you can't get your number into the 
Standard/Spec, then jockey around with the "method of measurement".  I own and 
have measured many of these parameters on an Atlas 210X a few years ago. My 
results differ markedly from the Table. Anyhow, it is an interesting guide.

There is another set of radio measurements available in the archives at:
    http://www.arrl.org/product-review
The big difference is that the ARRL also reveal their lab "measurement method" 
on that web page, in:

As far as dynamic range goes, ask the question whether you could tell the 
difference between a radio with the published dynamic range and one which has an 
"infinite" dynamic range under normal ham operating conditions. In other words, 
what is "good enough", especially in light of other specs, radio weight, size, 
power consumption, ergonomics, etc.?
