Changing IF frequency changes the location of birdies. If you have a selection of IF frequencies to choose from, you can move a birdie away from a frequency you want to hear. For example, if you have a birdie at 460.000 MHz and want to monitor that frequency, changing the IF frequency from 10.80MHz to 10.85MHz would move the birdie to 459.950MHz. That allows 460.000 to be monitored without interference.
The x36 scanners have this feature, it is under the Miscellaneous tab of the Profile Editor, the button labeled Intermediate Frequency Exchange (IFX). You can list frequencies that have birdies using the default IF frequency, and the alternate IF frequency will be used for those frequencies.
