Fwd: [Mw] Amateur Deep Space Network Yahoo Group



I have been asked to forward this to the Amsat and SETI-League reflectors.
I'm
not sure if this will be a repeat posting of this, so I appologize if it is.

> Here's something unusual, but probably of interest to the group. Paul Marsh,

> interest in Venus Express and Mars Reconnaisance Orbiter reception at 8.4
> GHz. Several on the various ham and radio astronomy lists I belong to have
> expressed interest in attempting reception, so I'm forwarding this notice
for

> Distance was 45 million miles.  A one meter dish was used.
