U16 is the RTC (real-time clock) chip: http://www.nxp.com/acrobat_download/datasheets/PCF8563_6.pdf PCF8563 In theory, frequency pulling is possible via C60 while monitoring CLKOUT (32768Hz) on pin7. The datasheet recommends a 5...25pF trimmer capacitor. In reality this might be difficult since U16 must be powered up during the alignment... -- View this message in context: http://n2.nabble.com/accurate-time-tp2442818p2443883.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
