Hi Chris, the Kenwood TCXO module is quite adequate because the microwave transverter LO is the major problem... let say a 10GHz/144 transverter LO xtal osci is 106,500MHz and multiplying up to 10GHz / fxtalX96 / is more critical to get exact 10368,000MHz....

Thanks. > 29/06/2012 11:36 Thanks, is it worth even thinking about, or is the Kenwood add on CXO module more than adequate? Only reason I ask is I will be using the ig as a driver for a microwave transverter. -- Best Regards, Chris Wilson. ______________________________________________ ime-nuts mailing list -- time-nuts@febo.com o unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts nd follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
