BUBJgCT: Developmenu of the RT-4-9 and RP/A-49 with 25X1A5a1
6. Contractor's Performance:
a, On Schedule and Expected to Remain So: No
b. Within Obligated Funds and Expected to Remain So: No
c. Satisfactory Technical Progress: Yes
7. Project Status:
The contractor has delivered two RT-49 transmitters and one
RP-4+9 power supply. One of the transmitters and the power supply
are considered engineering lab models and were not subjected to
an analysis and appraisal. The transmitter delivered on 25 Jan-
uary been sent to the OC-E/R&D Laboratory for evaluation.
25X1A5a1 hashas finished a third transmitter, but will hold this
unit until approval has been received on the second unit.
The second RP-49 is being fabricated and is scheduled to be
delivered on or before 8 March. A breadboard model of this power
supply had been set up for this visit and was able to
demonstrate a circuit which will provide overlo protection with-
out the use of fuses or circuit breakers. This circuit uses semi-
conductor sensing devices and a relay and will reset itself when
the cause for an overload condition has been removed.
25X1 A5a'
The RP/A-4 is still in the breadboard stage without a use-
ircuit , "W has promised to have a working circuit 25X1 A5a
able circuit.-
by 28 February. If a satisfactory circuit has not been developed
by 28 February, it will be recommended that the RP/A-49 project
be removed from or that a new approach be made to the AC 25X1A5a1
power supply requirement,
The RT-4+9 20 watt feasibility transmitter has enjoyed a
successful change from PT-657 transistors to PT-1623. This unit
is being optimized on band 3 (12-24+ mcs) and has been found to
function well out to 27 mcs, A tune-up key is being added to
the transmitter which will reduce the amount of drive to the
output stage and prevent transistor burn out when the trans-
mitter is not matched to the load. After tunin
matching network, the regular key may be used.
