Operation:
	The station was not operating upon arrival.  It was found that the interface board did not turn off the transmitter after transmission; the station was apparently turned off by the safety switch.  Also found that the transmitter could not be tuned to proper frequency and that the temperature sensor had failed.  Replaced interface board, transmitter, and temperature sensor.  Installed new type antenna, added three batteries, and raised solar panel.  Tower not raised.
