What we should do:

• record the times of starting the system, and also when the system is closed down.
• record any irregularity of the system, e.g. when the antenna go stuck, or the display did not continue to work ... in the case of such an irregular behaviour, it is best to keep note of the slightest detail!
• record all your actions to the system. Write down the time and what you've done, whether it's the move to another position or the change of the frequency grid.
• if you find anything remarkable, unusual, irregular, or simply new or noteworthy for yourself, write it down. If you want to comment your joy about a spotless result or your dispair about interference, don't hesitate to write it down ... it may later be helpful for your memory when
• it is better to write down as much as possible: the power level when the telescope reached the new source ... make a small sketch of the spectrum, indicate interferences ... if "record" is activated, much of this will be stored in the record file, but nonetheless it is good have it on paper under your eyes ... to see what values you get later in the observation period
• add your comments and explanations ... like "missed the sun again"; write down your impressions and thoughts ... even if you one hour later find out that you did something wrong or your interpretation wasn't correct ... you might have forgotten all that when you look at the data the next day! but then it is too late to exactly reconstruct what you had been doing!
• when you try out something or run a test, record what you do, why you do it, your thoughts and findings

• paper is patient: better write too much than too little.
• any piece of information not recorded will be lost forever!
• you might think: "Oh, I'll remember that later" ... but then someone comes and disturbs you with other matters ... and you may then no longer remember it accurately ...
