I've seen units that do the switch electronically. If there's energy at the external input, the internal source is switched off.

It has an external frequency input, but I can't find any switch that would allow me to turn off the internal oscillator and use an external supplied frequency. It has switches on the front panel to switch between an internal time-code and an external time-code, but no switch for the frequency standard. I've tried locating a jumper or switch inside, but there are boards on top of boards and I don't want to start taking it apart unless I know that there is a switch or a jumper on the bottom. Anyone have a manual or one of these units? Thanks for your help. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
