If you have a sked with me on 20 meters, I'll be there a half hour before, tune the rig, go get coffee, and turn up the volume so I can hear the abc de xyz. In case our clocks aren't exactly correct.
Also not a critical app.
Timing fuse cords on nukes? I want cesium decay precision.
Accuracy is fine. For the application.
