Hi John, The clock's accuracy is typically +/- 2 seconds per day. If that doesn't suffice for a long trip, and you don't have a timepiece to correlate it to, you could attempt to adjust the frequency of the clock crystal closer to 32768 Hz. This usually requires some long-term experimentation. Putting a frequency counter on the crystal will load it down unless you have a very low-C FET probe.
There's a capacitor connected to the crystal that can be adjusted in value slightly without impacting the oscillator. It's easy to slow the clock down; just parallel a small amount of additional capacitance. Speeding it up requires a decrease in capacitance, which means removing a surface mount capacitor first. Let me know if you need advice on how to do this. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
