bad data - MFRSR - site E9

From about 960614 to 960725, the data emanating from the MFRSR at site E9
was very noisy indicating that there was a problem with the instrument.
On 960725, the MFRSR head was changed and the problem appears to have been
solved.  The data quality could be poor prior to 960614, so beware!
