Isn't the end result that a receiver with much less attractive phase noise numbers can probably perform just as well as the Orion in the current noisy signal environment? Is this truer for phone than CW?
Am I missing something?

Yes... keep in mind that the Orion low receiver phase noise means that there are "fewer internal osc signals" (phase junk) to mix with the incoming RF, giving you purer reception. So, a simplified (but not extremely accurate) way of looking at would be that your reception would be 50% better! If the adjacent channel "phase noise generators" were clean then you would then be 100% better.... (as I said, a simple way of looking at it) :-)
