in the previous trip report dated 21 January. At the time of
the visit, the contractor had been running the tests for four
days. Test results indicate that the demodulators "stack-up"
Subsequent to a telecon with on 4 March 1963, the
formal on-the-air testing was scheduled to continue until
22 March. However., the project engineer recommended during
the telecon that the testing be terminated within the next
several days. The data that was being obtained was becoming
increasingly repetitive and no great service would be performed
by continuing to take additional data of this type. It was
felt that the effectiveness of each demod had clearly been
demonstrated at this point. On 5 March _ was informed to
stop the tests and begin preparation of a comprehensive engi-
neering report describing the tests and performance of each
demod.
