[Elecraft] Why is KX3 phase noise so much less than the K3 ?

It's easy to demonstrate this.  My real-world setting is Field Day,
and the example is actually what my team experienced.

Take four rigs in a Field Day setting, within 100 yards of each other.
Make sure one of them is a K3, and the others are Y/K/I types.

On the same band, any of the Y/K/I rigs will create so much wideband
[phase] noise on transmit that none of the other rigs are usable on
receive.  Transmit on the K3 and all the other rigs are usable on
receive (same band, mind you).  No BPF required in this case.

This is very real-world.  It's also the reason DXpeditioners use
Elecraft products in close proximity with no ill effects.  Field Day
is just my Regular Joe example of the same thing.

Yes, there is a huge difference - not just a statistic for the charts.
