A weak signal is currently being observed over VK.  We're waiting to see if
it's a stray signal or something from AO-40.  The amount of drift roughly
coincides with the expected Doppler changes over time, but the real test
will be at LOS, in 5 hours time.

I'm not able to monitor directly, but keeping in touch with Dave, VK3DXL via
IRC and helping with tracking information.
