TR3174 Eureka MKII with
PSU
254A (UK)
Eureka &
Rebecca
formed a system of ground based beacons and airborne direction finding
equipment
designed initially to assist the air-drop delivery of supplies to the
Army
or Resistance groups in occupied Europe.
Eureka was the
ground
based beacon and Rebecca the airborne station.
The ground
based
beacon was a super-regenerative receiver and transmitter
operating
in the frequency range 214 - 234 MHz, powered from a battery via a vibrator power
supply
unit. A portable tripod mounted aerial was erected when communications
was
required.
The system was
initially
designed by TRE, and manufactured by Murphy and Cossor. A number of
different
versions of Eureka were designed and manufactured in both the UK and
the
USA.
Details of the Rebecca
Display
Unit, Indicator Unit No. 96, will be listed separately under its own
type
number.
