          iMet-1/iMet-4 sondes do not provide a serial number, and so auto_rx [generates](https://github.com/projecthorus/radiosonde_auto_rx/wiki/Model-Specific-Notes#intermet-imet-1--imet-4) a serial number based on launch time and transmit frequency. DFM sondes do not regularly transmit their serial number, and so data from these sondes should not be uploaded before the serial number is known.

          Some sondes (e.g. iMet, LMS6) do not provide the date portion of the timestamp. In this situation, the date portion should be added on by the receiver. An example of how to handle this problem is [available here](https://github.com/projecthorus/radiosonde_auto_rx/blob/master/auto_rx/autorx/sonde_specific.py#L13).
