COMMUNICATION INTELLIGENCE SUMMARY, 2
General.-Traffic volume normal for Sunday. Receiving conditions were fair but bulk of traffic derived from the
major shore circuits. Solution of new
call system progressing satisfactorily but volume of accumulated traffic in new system not yet large enough to
permit more than casual identification
of individual calls. The number of alternate calls for major commands is increased over last system.
So far there are seven alternate calls
for the Combined Fleet.
Third Fleet traffic is still on a very high level. The combined air Force traffic is also very high with the Commander
of the Combined Air Force originating
many dispatches. It appears that he is now in Taiwan. Traffic to SAMA and BAKO is on a very high
level. Tokyo and The China Fleet
Intelligence bureaus are originating periodic dispatches, these from Tokyo being prefixed WIWI. There were
several high precedence dispatches from
Tokyo with the major fleet commanders as addressees.
