Telemetry interference

The ground station began tracking a different radiosonde at 18:08:26.
Pressure and temperature data were recorded from this point to the end
of the sounding at 18:12:52 but are incorrect.  No wind or RH data were
recorded after 18:08:26.  The sounding up to this point is okay.
