I bought two of them.
The nominal frequency was 45.1584 MHz.
The measured frequency of one of them was 45.158230 MHz,
the other measured frequency swam slowly to the desired value : 45.1584000 MHz
Obviously, after a while it slowly drifted away from here, but how much was the error of the measurement or the oscillator could only be told by a frequency meter with an atomic clock .
Excellent oscillator with very little jitter.
