Hi Max: I could give you a long discourse, but first,
before you get numbers fever pick up the latest, or next to latest, ARRL
Handbook. There is a section on reciever specs that bears close scrutiny.
After you get that digested, remember that many older rigs tests were taken
with 20 kHz interfering signal spacings, offsets, while later tests use the
much more stringent 5 kHz offsets. There is a vast difference in the
performance of the same rig when the spacings are reduced - and a comparison
of rigs using different offsets results in meaningless comparisons.
Next, remember that some rigs are "racers," all out performance rigs most
suited for serious DXing and contesting. Other rigs are "runabouts," most
suited for less demanding activities. That difference makes "spec sheet
comparisons" an "apples and oranges" affair as the contest rigs essentially
use a different yardstick than the general purpose rigs.
Now, here in the real world, having collected quite a number of rigs and
participated in a number of rig shootouts - the consensus is the Omni VI+ has
the best overall reciever performance, the main reciever on the FT1000D is a
fair second, followed closely by the Paragon and the PII. The Jupiter is a
pack leader, excellent among rigs in its price range.
Hope this helps
