Hi Trying to troubleshoot those racks *without* being able to see the timing is harder than if you can. This gizmo should trigger at the top of the minute. Did it trigger? That’s much easier to catch if you can see the minute transition. If the rack goes down, it needs to be back up fast…..

There are more sophisticated units that include controls for the tape recorder so you could auto search to a certain time. Multiple displays could be used for locally generated time, time received from a remote site by fixed line or radio and time from data or video recorders.I have a number of them and one sits above my GPStar as the LCD on the GPStar is hard to read from across the workshop and it lets me have time available while showing timing or satellite status on the GPS. Just picked up 3 more (RAPCO 104 anyone have a manual for these) at the weekend. > Robert G8RPI. > > From: Bob Bownes <bownes@gmail.com> > To: Discussion of precise time and frequency measurement <time-nuts@febo.com> > Sent: Sunday, 22 January 2017, 18:33 > Subject: Re: [time-nuts] purpose of time of day display units > > > #5) Everyone likes blinkenlights. >

They also help weigh the rack down :-) I took this photo before I saw the thread.
