    Switch 2 - TimeTAG
    If this switch is ON, then a precise time code (for MLAT) will be generated
    by the decoder for each received frame. The adsbPIC-decoder time tag is
    based on a 12MHz clock. (Some other decoders/receivers use a 20 MHz
    clock instead)
    The adsbScope software via USB can activate the time tags by software. If
    this was done, then the decoder will send time tags even if the switch is in
    OFF position. The time tag can be used to triangulate aircraft position in
    collaboration with other decoders. If you don’t participate in such a network,
    then you should deactivate the time tags to reduce the load at the
