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? -- Paul Nicholson -- |
