Hi Stefan, The noise at Orford is mainly due to lightning activity off the coast of New South Wales. https://dl.dropboxusercontent.com/u/101251787/temp/l.PNG See: http://www.weatherzone.com.au/radar

Hi Joe, Yes, winter has less noise. The best time for the reception of DK7FC at Orford was in April, during Equinox. I have a rubidium oscillator and GPS unit and will try to set-up a receiver using

Hi Paul, Thank you the the information on the signal level required to decode a message. To obtain a 92 uHz bin width in Spectrum Lab the settings would have to be something like https://dl.dropboxus

Hi Paul, GPSDO for the local oscillator? And why is a GPSDO better than using just a Rubidium Oscillator for EbNaut? Regards, Edgar Moonah, Tasmania.

Hi Paul and Andy, My question on the use of GPSDO for EbNaut was to improve my limited understanding of the equipment required. It was not intended to directly compare Rubidium Oscillators vrs GPSDO.
