AR88 Communications Receiver
During the war there existed an insatiable demand for ground station receivers for the multifarious jobs of point to point communication, air to ground reception and intelligence monitoring.

In the last stages of the war a receiver came into service which was regarded by delighted operators as representing the (then) ultimate for communication purposes.

This was the AR88
, which from its ruggedness, its electrical specification and its appearance both inside and out  that it had been developed almost regardless of cost.

Three versions of the AR88 were available, the basic model, the AR88D with output into 600ohm balanced line and the AR88LF with long waves. .
 

In the RAF service these models were subjected to modifications to become R1556/1556A/B. Use of the LF version had the advantage of the 200 kc/s Light Programme transmission.

AR88D R1556A, 535 to 32000 kc/s in 6 bands.

Band 6 :- 22000 to 32000 kc/s.

Intermediate Frequency
455kc/s The IF frequency may vary with model.

Power Supply
:- 100 to 117, 117 to 135, 135 to 165, 195 to 230, 200 to 260volts (50 to 60 cycles)
It is possible to operate the receiver under portable conditions if 12 amp from a 6volt accumulator can be tolerated; for this service a vibrator  power unit type M1-8319 was required.
