Yes.

Vienna Wireless Society K4XY Field Day multiple times. We had an all K3 
field day couple times with 2 K3s on 40m. One CW and one SSB.  Antennas 
were dipoles or two element wire yagis both pointing West with about 300 
ft separation E-W ( yea, CW station was in the beam of the SSB station]. 
Either K3 could dial close to the other with little issue. When we tuned 
past the other station was just a strong station. I guess plenty of one 
over r-squared isolation?
