The higher band is used as the desired band, thus the local oscillator can be lower than FM radio band. The oscillation frequencies were chosen to range from 66.6 MHz to 86.6 MHz, resulting in a tuning ratio of 1.3. Minimizing the LO frequency facilitates the design of the oscillator, making it highly desirable.
One of two things will happen. (1.) Your landlord will return all of your security deposit. (2.) You'll receive a letter with itemized deductions that explains why some or all of your deposit is not being returned. Most states give landlords 21 to 60 days to return the deposit.

Within 30 days of moving out, the landlord should notify you, in writing, whether he or she is going to make any deductions from your security deposit for repairs for damages you caused.
