While not 10.7 MHz you may find the circuit diagrams of the 145/29 MHz linear transponders for the RS series of satellites of interest. They are on the RadioSkaf website at http://tinyurl.com/RadioSkaf - Click on the Forum menu option - UnderĀ Satellite "Radioskaf" select the Transmitter topic - Then click on Schemes of repeaters There are a number of circuit diagrams there available for download as JPEGs Also see the Receiver -> Receiver CL (Command Radio Link) section 73 Trevor M5AKA _______________________________________________ Sent via AMSAT-BB@amsat.org.
