Struggling with "frequency accuracy"
Recently, I am struggling with "frequency accuracy for measurement" because I've released "programmed crystal oscillator on my tindie store and I should know how exact it is. But unfortunately I don't have frequency standard such as rubidium oscillator, BUT also I got to know that GPS trained accurate signal can be obtained even from $8 cheap GPS module! Here I've tried how it is accurate. Please take a look. (indeed, still I am not sure how it is accurate. If I believe the signal from GPS is accurate, then that should be accurate,,, yes it should be...)
