HF+ Discovery: calibration value

Dana Myers

I received my HF+ Discovery on Friday (DHL did a wonderful job for me).
As an initial test, I ran a Zoom FFT test against WWV 15MHz, noted that
the receive frequency was ~2.5Hz high, recorded the calibration value
from the HF+ (-152), and tinkered with the calibration value to bring
the WWV carrier within ~0.2Hz.

However, despite flashing the calibration value, power cycles to the
HF+ seem to always revert it to -152 (and the WWV carrier reads ~2.5Hz

Is this the expected behavior?
