pip faded due to excess range.
At 265 mc/s had four or five contacts which are
presumed to have been noise. These are not listed. A
video
signal was never observed, only a weak audio tone, about
1200 c.p.s.
At about 450 mc/s a video pulse gave trouble
throughout the whole patrol. This was definitely a fault in
the APR, and was eventually located.
Contact #12 considered to be a friendly set
based at Exmouth. If so, information that we could expect to
pick up such a set would have been helpful. We were forced to
consider contact enemy, and to maneuver accordingly.
Contact made 200 miles from Exmouth. Still
present at 250 miles 0500, 6 November (CGT).
Radar Interference
Two contacts were made, both were friendly
submarines.
The first contact was made at 2215 (I),
22 September 1944.
The second contact was made 150 miles south
of Lombok with JACK and PARGO. Contact was made at 10
to 12 miles.
Casualties
No SJ casualties of importance were experienced
during this patrol. Several minor repairs were effected, but
all except one during daylight hours.
The antenna rotation mechanism is clumsy. More
flexibility is needed in shifting from hand to power. A
larger PPI scope would be highly advantageous. When working
close to coast it is often difficult to distinguish small
islands and rocks from ships. This could be accomplished
much more easily with a larger scope.
Information is needed on all allied radar sets
likely to be encountered, particularly British and Dutch
submarines and planes, and those land based stations through
whose transmission range we pass. |
