That depends on what kind of a system the local oscillator is part of. In a simple AM receiver, it's typically 455 KHz above the frequency of the incoming signal of interest. In a consumer FM radio, that figure is 10.7 MHz above. In a 'legacy' analog microwave receiver, it's almost always spaced 70 MHz from the received carrier, and since the ubiquitous advent of split-mount digital microwave equipment, with the RF system clamped to the antenna, there's no telling any more ... you always have to look in the book (if that information is even included in the book).
Frequency is measured in hertz (Hz) and represents the number of vibrations or cycles that occur in one second.
That's the frequency of the vibrations.
Frequency, measured in Hertz (Hz)
Frequency of the wave is the number of crests passing at a point in one second. Actually crests are not passing through, but it appears so.
The number of periods per unit time is called the linear (or ordinary) frequency. Specifically periods per second has a special name that is "hertz."
Frequency is measured in hertz (Hz) and represents the number of vibrations or cycles that occur in one second.
It is called the frequency. The SI unit is the Hertz. One Hertz is one cycle per second.
That's the frequency of the vibrations.

The measurement of the number of vibrations a wave produces each second is called frequency. It is typically measured in hertz (Hz), where 1 Hz equals one vibration per second.
The number of vibrations per unit of time is known as frequency, and it is typically measured in hertz (Hz). One hertz is equivalent to one vibration per second.
The frequency of vibration refers to the rate at which an object oscillates back and forth in a given time period. It is measured in Hertz (Hz) and represents how many cycles of vibrations occur in one second. A higher frequency indicates a faster rate of vibration.
-- Determine the number of revolutions, vibrations, reciprocations, or full oscillations in one second. -- Multiply that number by (2 pi).
The number of vibrations a wave makes in a certain amount of time is referred to as its frequency. It is measured in hertz (Hz) and represents how many complete cycles of a wave occur in one second.
The term hertz is a unit of measurement for frequency, which represents the number of cycles or vibrations occurring in one second. So, when we refer to a wave's frequency in hertz, we are quantifying how many wave cycles occur per second.
