Yes, accurate tuning is possible with a kHz precision, but since stations are positioned with a 0.1MHz gap I have restricted it. Also, default value of tuning from class for fm band is 0.1MHz.

A problem I encountered with a more accurate tuning is that the seeking increases freq by 0.1MHz aswell, so if you are at 87.75, seeking will check only if signal is >0 for stations 87.75, 87.85, 87.95 and so on, missing any stations in those frequencies.

Why do you need a more accurate freq tuning anyway?
