When WWVB changed to BPSK, the phase-tracking receivers were rendered inoperative.
Paul Swed has a tested design for a Costas Loop receiver front end and demod that properly tracks the BPSK carrier phase and routes it to a 117A or similar receiver. There are also some hacks that, knowing the time, invert the WWVB signal phase, in sync with the data, but no product that I know of. -John =============== > Are there any tricks to getting a HP 117A to lock to the current WWVB > transmissions. > I have read the thread for the Spectracom receivers. > Will this work with the 117A? > > Thanks > 73 > Glenn > WB4UIV > > > > > _______________________________________________ > 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. > > _______________________________________________ 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.
