a. Observations of prototype of MEW at Tarpon Springs, Fla.,
indicate satisfactory results. Nine thousand to 11,000 targets
were plotted in eight hours, some targets as far away as 160
to 180 miles. This is considered excellent in view of the fact
that personnel operating this set was not thoroughly experienced.
b. Final specifications for Radio Set AN/CPS-1 have been
completed and forwarded to the General Electric Co.
2. Frequency Change Kit CPSI-Q1.
C. The development of the frequency change kit is under
consideration for use with Radio Set AN/CPS-1. The kit will
consist of the necessary materials and equipment to effect
