Hello All,

We will be testing automatic mode switching on AO-51 for 2 days each week on Wed & Thur this month, except for Dayton week. The rest of the time AO-51 will be in 'normal' mode.

I will do the first mode switch on an early US east coast pass between 1300-1500Z, 2 May 2007. The AO-51 schedule for May on the AMSAT web site has been updated. http://www.amsat.org/amsat-new/echo/ControlTeam.php

Enjoy these modes and send comments and requests to the AO-51 Operations Group ao51-modes@amsat.org
