It's worse than that.
There are TWO independent frequency references.
The obvious one is the TCXO, and the other one is the codec clock.
The ways they are combined in the main RX and in the sub RX are quite different,
which causes the observed frequency differences.
There is no practical way to calibrate this out permanently.
