Before I bought my K3, I discussed the radio with someone in the
booth at Radiofest, a small hamfest held near Monterey, CA.
After I had learned a very little bit about the radio, I had my
wife (KI6SLX), a retired QA engineer for Apple, discuss UI
issues. When she said it seemed OK, I wrote a check.
I like Brian's idea of simulating contest conditions to test
receivers. Such a simulation would need to be reproducible and
good enough that it can't be gamed. For testing CW reception,
perhaps a fixed set of signals modulated through a very linear
SSB modulator would work. That could give at least 2KHz of
signals for the receiver to handle.
The West Valley Amateur Radio Association field day operation
sometimes has 3 signals active on one band (CW, digital, and
SSB). We manage to get by running QRP with K3(S)s, KX3s, K2s and
carefully placed antennas. For CQP, we managed to run two
stations on a band at 100 watts with similar equipment and techniques.

I want to know how well a receiver is able to separate a weak
signal from strong signals 50-100 Hz away. It would be
interesting to speculate how such a measurement would be done.
Let the RX use whatever analog or digital tricks it can to
achieve the above.
Your idea of simulating a contest with a hundreds of signal
injected at various random frequencies to gauge RX performance
has merit.
Have you overlooked the MM, FD and DXpedition RX uses which in
fact push the dynamic range and mixing limits today? There are
MM stations which operate two transmitters on the same band.
