When you tune the radio in to a particular station, you will align to maximum signal. Then when you align the MT you will align the MT system to maximum signal. Since this is done well after the radio has had a chance to warm up, and not enough time for the oscillator to drift, the 2 signals should be exactly the same with no tonal difference. Once the MT is set, you will be able to turn the radio on when cold and the MT will bring the oscillator to the correct frequency for maximum signal given your dial setting for the station. then, as the radio warms up and the oscillator tends to drift, the MT will adjust the oscillator to maintain the maximum signal. It works well. I have 2 37-116's and a 38-116 and when properly adjusted, the MT keeps the signal strong and clear.

As morzh said, if you tune in a station with the MT on, It may lock in with the dial slightly off the correct frequency. Always tune with the MT off. the MT will then hold the frequency even if the local oscillator drifts, which it does do as the radio warms up.
