The technical history of the Würzburg radar system (1937 - 1945)

It is interesting to notice, what had been stated in
the British wartime report: “Technical Note No. Rad. 203, of June 1944".
Conclusion (page 12-13)
While no investigation of accuracy of the (Würzburg) equipment, either absolute,
or in comparison with corresponding British apparatus, has yet been made, it is
safe to state that the operation is fairly easy, even with comparatively
untrained personnel. The smooth following of range - essential for use with a
predictor - is particularly simple to perform, and the split is very
satisfactory, provided that the echo is well above mean noise level.
A consequence of the fact that the dipole rotation is not locked to the
recurrence frequency, is that for varying dipole positions different amplitudes
of pulse are received, ranging from zero to maximum. These are all superimposed
on one another on the trace, so that the echo is a solid patch of illumination
with, quite frequently, no break in the time base. This tends to make searching
rather more difficult than is usually the case.
The circuit design in these two units is efficient, and sometimes ingenious, and
no circuits faults have yet occurred since the equipment has been in use here -
i.e. for two months or more. Setting-up can be performed simply and quickly.
The construction of both units (ANG 62 and EAG 62) leaves nothing to be desired,
from the point of view of interchangeability of units, robustness and simplicity.
No comment can yet be made on the quality of components, which will be dealt
within a further report, except the remark on their smallness as compared with
their British counterparts.

Since the circuit drawings started in early December 1943, we may assume that this Würzburg apparatus (FuSE 62 “D” or FMG 39T/D) had been seized somewhere in September or October 1943, in Italy. As no other continental war-theatre had been in the hands of the Allies. The RAE trials took place at Farnborough.
