Hi Rob,

Please don't be worried by this activity, we are just doing some testing of different groundstation equipment at various locations to establish the best operating procedures. This will enable us to ensure the future health of the spacecraft over time.

We are not trying to make any actual changes to the current operating schedule.

thanks

Graham G3VZV

I wonder what attempt was made,and if the attempt was by AMSAT-UK, I see the last attempt failed

and returned an Unknown command.
