Ivan, I don't know if there is a significant difference between the 2 crystals or not, but I suspect that either will work.
The crystal is only for the Real Time Clock. Put one crystal in and keep tabs on the time display for a few days. If it is off drastically, try the other crystal. If it off by only a little bit, try adjusting C19 as indicated in the manual on page 12. The normal clock accuracy is better than 2 seconds per day. If you have an accurate frequency counter, the clock frequency should be 32768.0 Hz (measure at U3 pin 2). 73, Don W3FPR Ivin Flint wrote: > I am confused on the X1 Crystal, cylindrical 32.768 crystal.
