It took so long time because my free time is small, due to my dayly work.\nThe goal was to get a linear transponder also available at areas where space and weight is little (with the 1 cell cubesat as a guidline). \n\nAt the moment I am working to get a few more of these transponders, and make it available for people/groups who are interrested.\nThe design is very small and takes lot of time to get it fully assembled (with microscope and very small solder iron tip).\n\nThe transponder design itself is even smaller than you mentioned. It can fit on a 7cm x 7cm board (size of a MiniDisc casette) when needed.\nI have added some 1cm strip around it for mounting purposes, what makes it a 9cm x 9cm board, what should fit in a qubesat.\nThe total circuit is made for 3.0V to 4.0Vdc supply, where a light weight 3.7V Li-ion or LiPo cell-phone battery will fit very well.\n\nWill be continued...\n\n73 de PE1RAH\nWilliam Leijenaar\n---\n\n \n\n \n\n\n\n\n\n> Date: Tue, 2 Dec 2008 14:36:50 -0400\n> From: [email protected]\n> To: [email protected]\n> Subject: Re: [amsat-bb] Pico transponder\n> CC: [email protected]\n> \n> William --\n> \n> This appears to be a linear transponder on a 10cm x 10cm board.
