Randy, 10.238 MHz was very likely used for GPS applications. With GPS, it is more important to keep LO harmonics away from the L1 input frequency than to use any particular round frequency. The IF can be anything suitable, as the baseband data is recovered using an NCO which corrects for LO offset and drift, as well as satellite Doppler.
Other common GPS frequencies are 10.949297 MHz, 16.368 MHz and so on. Murray ZL1BPU _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
