I see no reason why we can not vote on the \ndesigners decision with our support dollars. Personally, I am giving \nall mine to P3E.\n\nThe fact that they are \"designing the ground equipment too\" is of no \ncomfort to me. My S band gear is on the tower and operating.\n\nIf AMSAT thinks this is such a great decision then let them find the \nmoney to support it without the majority of us.\n\nDean Shutt\nAL7CR\n\n\[email protected] wrote:\n> I totally agree with you.\n> \n> Les W4SCO\n> \n> At 02:38 PM 9/7/2006, you wrote:\n> \n>>Rick,\n>>\n>>I am in _TOTAL_ agreement.
