If the COR on the sub receiver is only tripping on rare occasion, no  
problem. But if it's tripping frequently, say during CW keying, it may  
alter the keying envelope and increase the keying bandwidth. I  
strongly suggest not operating this way. You might consider a lower- 
gain diversity antenna on bands where this occurs, or moving the  
antenna farther away.
