Just like any other computer with volatile memory.... IF you don't tell
the computer you are shutting down, it doesn't know and therefore
doesn't have time to save the information to NON-volatile memory.

Respectfully, is that really true? The K3 needs to be shutdown via
the Power switch due to some sort of shutdown procedure, (or internal
timings issue), within the radio?

I would also comment with Knut, AB2TC, that one must always turn the
radio on and off with the power switch. This allows the internal
workings to store the data. 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.
Years ago we had "the big switch" which was used to shut the station
down. Today with all of the computerized gadgets, power down in
sequence is more and more of a must do.
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.
