Many WAAFs volunteered to
accept the extra work in the T-block and Gretta became one of them.
Helping to maintain an unbroken transmission of high voltages, pulses
and frequencies, changing transmitters when necessary, and keeping station
records. Among them was the setting up of calibration tests on top of
its towers when desirable. This became a challenge for any fit and adventurous
mechanic, but when an energetic and willing WAAF found herself with
the job, male personnel perked up a bit. They had done their stint in
the readings required - now it was her turn.
As Gretta explained to me,
her ignorance of the exposed wild conditions to be expected at 360 feet
above ground level spurred her willingness to satisfy the demands of
the job above her. But someone's descriptions of the lonely surroundings
while sitting on the top platform inspired her to pack layers of newspaper
round her body beneath her uniform and trousers. Nobody seems to have
thought of providing her with flying suits, as happened in later years.
Colin Latham's description
of his adventures and fears climbing the wooden CH towers could equally
be applied to Gretta's exploit climbing a steel CH tower. The R/T connection
was checked; and a theodolite issued, which was held to her by straps.

Evidently the first climb
section was achieved without mishap, and the second, and the third,
and on up to the 200 ft platform. Only a short rest was needed before
realising the climb was an enjoyable experience and she was keen to
complete the last three sections to the top, all within the confines
of the now narrowing steel ribs leading to the top platform area.
Gretta recalled that her
brief theodolite training had been enough to manage the radius vectoring
needed, all the time trained on a circling autogiro at a predetermined
height and distance. Readings were passed by R/T down to the Ops Room
where map references were completed and calculations determined.
The return down to the ground
from her lofty vantage point seems to have been without incident. But
it was an exciting memory of her time at Bawdsey that she never forgot.
Recalling at the same time the wonderful views of the surrounding countryside;
across to Felixstowe, west to Woodbridge and observing aircraft landing
at the special base there, and across the North Sea seeing, she remembered,
many ships in the coastal waters. And she was rather saddened to learn
that three of the four steel towers had been dismantled and taken away
in the 60s - in common with many similar towers from the coastal radar
stations round Britain.
One day she climbed up towards
the 200 ft platform to help down a male colleague who had 'frozen' on
the ladder, and evidently couldn't find the nerve to make his way down
unaided.
Whether her 1942 calibration
climb was a pioneering achievement we didn't discover. But Colin has
since published the experiences of other WAAF personnel who, in the
years that followed, carried out calibration tests from the tops of
the steel towers quite frequently.
Now, in this year 2000, the
last remaining nostalgic tower was demolished in one piece - the BRRG
members agreeing to it falling to one side.
