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.
