Maybe you are a bit hasty with the power switch?

When the move the VFO knob, the new frequency isn't written into the
EEPROM straight away, it will only be written if the knob stays still
for a certain period, or if you change another setting like operating
mode. This is to keep the number of writes to the EEPROM at a minimum.
I forget what the timeout is, maybe 10-12sec, but if you wait a bit
before turning the K2 off, it will hopefully retain your QRG.
