T06-3A - British Early Radar MCMs
CV56 Early strapped S-band MCM. Strapped NT98. Late 1941
CV56A CV 56 frequency selection. About 1942
CV56B CV 56 frequency selection. About 1942
CV56C CV 56 frequency selection. About 1942
CV64 Early strapped S-band MCM. Designed by BTH as BM717 as replacement for CV38.
CV69D Power magnetron, 450 kW peak pulses. The family of four frequency variants was later titled from CV1475 to CV1478
CV76 Early warning hi-power MCM. Similar to CV56 but operating at higher magnetic field.
CV160 S-band high-power magnetron, 1 MW input pulses, coaxial output. Early 1944
CV186 Frequency variant of CV64, airborne
CV192 Conduction-cooled S-band magnetron for airborne H2S
CV208 Double Stem Very early production sample of CV208. Soon replaced with the single stem variant below, for interchangeability with the BTH CV209. Extremely rare, second half 1943.
CV208 Single Stem Early X-band MCM, GEC E1487 design, modified to single stem to be fully interchangeable with CV209
CV209 Early X-band MCM, BTH design
CV214 Early X-band MCM, waveguide flange
CV1493 Very early unstrapped MCM, equiv. NT98C. About 1941
CV1494 Unstrapped MCM, equiv. NT98D
E-1189 Prototype Very early developmental sample. Predates the E-1189 brought to America by Tizard Mission. End July 1940. GEC.
NT98C Early unstrapped MCM, directly derived from E-1189. Later approved as CV1493
NT98D Early unstrapped MCM, directly derived from E-1189. Later approved as CV1494
REL 3C Canadian REL unstrapped S-band magnetron. Made by Northern Electric to the CV38 design. 1941
REL 3D Canadian REL unstrapped S-band magnetron. Made by Northern Electric to the NT98 design. 1941
