During the past two weekends, WWVB was using its legacy AM/pulse-width-modulation signal. As of yesterday 21 March 2013, WWVB has stopped the twice daily 30 minute segments of this format.  Going forward, WWVB will only be broadcasting using its phase modulation (PM) time code protocol. 

Does anyone have a kluge to allow my vintage HP 117A to continue working?
