If you use a "master station switch" thus just dump the power supply then the radio may not store the data as required.   I recall the term "power down imminent" or PDI.

>> In another brand of radio to which I am familiar, there is a CPU timing circuit that assures the CPU is up and running before loading the operating code.   If this circuit is running too fast, it may cause a partial load and related error.  This circuit is basically a simple RC network, and with age the C value decreases thus making the timing circuit run too fast.   i.e.  not enough delay.
