Changing what is just the resonant frequency of the IF transformer should not alter the RF frequency.
Tracking is getting the aerial in step with the RF.
If the RF is low i.e.1600m instead of 1500m then you need to lower the oscillator, try a cap across the trimmer to alter its range. I think I have that the right way round, waiting for the corrections to pour in.
