Yes. Study my summary of ARRL Lab Tests of the TX cleanliness of a dozen 
or so medium to high priced modern rigs.

Look for rigs with very low TX phase noise in the wide plots. I haven't 
added the new Flex 6000-series rigs yet, but the 6500 and 6700 are good 
performers for phase noise. Also study Rob Sherwood's comparison of 
receivers for handling strong signals.

Phase noise is that "rushing" sound you hear off frequency when a strong 
signal is being keyed. Both TX and RX have it -- we hear it because the 
other guy is TXing it, and also because our RX contributes its own phase 
noise. :)  You want rigs that score well both ways.
