How i change the radio station jump from jumping from odd numbers to even numbers for example i want these stations in my radio 102.0,98.0,92.0..etc

Tune into 102.0 then hold button "1" for a few seconds (you may hear a beep as it registers). Tune into 98.0 and then hold button "2" for a few seconds. Tune into the next station and then hold "3" and so on. Now when you press "1" it will go to 102.0 "2" will go to its' preset and so on.
