The audio frequency is more to suit the passband of the radio.
1000 Hz does make the calculations a bit easier than 1500 of course.
As long as the combination of dial and Audio frequency add up to the
same actual TX / RX Frequency and your radio is happy with that audio
frequency chosen then all should be well.
