You may be thinking of "reciprocal mixing," a measure of receiver performance that is impacted by synthesizer phase noise, spurs, etc.

>> Like Don said, "not in receive", but in transmit, driving an Alpha 9500 to the full 1500 out, a close neighbor (about 5 blocks away) was noticeable on my K3 within 5-10 KHz of his transmit frequency.   That said, the FTdx5000 was MUCH cleaner than the FT-1000MP he had prior to obtaining the 5000.  The phase noise & key clicks from the 1000MP were horrendous but at least his huge signal did not pump the K3's AGC unless he was within my 400Hz filter passband.
