Hi,

During the last three Equinoxes I = have=20 attempted to receive DK7FC's
signal at QE37pd, Moonah, = Tasmania.

The=20 best result was achieved last April.

I=20 decided for next Equinox period, (20th September 2013), that I would =

The results will be = available=20 on the internet.

By the middle = of=20 August the system is to be set-up at Orford, on the
