Wireless Set No 88 WS 88 WS88

PURPOSE AND FACILITIES

The Wireless Set No. 88 is a small lightweight man-pack RT set for short range communication.
It may also be used as a ground station and for working from vehicles at rest or on the move.
There are two versions of the set, Type A with an olive drab control panel and Type B with a black control panel.
The difference lies in their frequency ranges (see below)

The set is frequency modulated, the maximum deviation being 15 kc/s Side tone is provided.
The complete equipment, including the battery, is fully tropical and can withstand immersion in salt water

The set is carried in the operators left-hand pouch which also provides stowage for a collapsible rod aerial and an instructional card (ZA.32991 Wireless Set No 88. Instructions Working No 2 Metal.
The battery and microphones, receivers, etc. are carried in the right-hand pouch.
A short wire “invisible aerial is also carried in this pouch.

FREQUENCY
Typo A and Type B sets both work on four spot frequencies, as follows : -

Wireless Set No 88 Type A
Channel A 42.15 Mc/s
Channel B 41.40 Mc/s
Channel C 40.90 Mc/s
Channel D 40.20 Mc/s

Wireless Set No. 88 Type B

RANGE OF WORKING
A range of up to 1 1/2 miles may be expected using the 4 ft. rod aerial, but this will vary considerably with the nature of the terrain and the climate. The range with the "invisible" wire aerial compares quite favorably with the 4 ft. rod.
