I have yet to find a RDS radio that switches when the signal gets to the point that I think it is worth switching, I always get better results by forcing a manual switch (every RDS radio I have used allows a manual switch by pressing the preset button for the current station again). They tend to hang onto the current frequency long after a clearer one is available.

It will be interesting to see if the new empeg RDS code finally meets my RDS AF requirements...
