Looks good but I didn't get a decode, just 'NK!'
at Eb/N0 = -0.2 dB.  I swept a range of frequencies
either side of +93 uHz in 5 uHz steps but nothing
better came out.

It was a noisy night again! Good reception overnight
7th/8th has been followed by noisy nights ever since.

Is the RPi running ntpd to maintain its clock?

ebnaut doesn't need superuser permissions, you
shouldn't need the sudo prefix.

Will you be trying again tonight with the same
timing and settings?
