Curious, but I'm wondering whether there are any artefacts that might have been caused by the weak GPS signal? I would feel more comfortable if the unit had its planned strong GPS signal throughout the test. I know it's meant to cope with that, but it might have thrown up an obscure software bug. Exactly how that might have nudged the frequency off I can't figure.
