Receiver AR88

The AR88 is a general purpose communications receiver made by RCA in the USA between 1941 and 1945. AR88s were made in large numbers for Service use. Most were sent to the U.K. and Russia for the War Effort.
AR88s came in 2 versions, the AR88D and the AR88LF (low-frequency version). The R.A.F. designations for R1556A and R1556B (the L.F. version).
The receivers evolved into the CR88, with crystal phasing, in 1946, and the CR88A with an 'S' meter. Later models CR91 and CR91A have the same coverage as the AR88LF. Moder SC-88 is like th eCR88 but shows only the band in use. CR88B is the last version, from 1951, and has a crystal calibrator.
The AR88F was part of a triple-diversity system known as the DR89 (made by RCA). This involved three AR88F receivers in a large rack, with a system for selecting the strongest signal of the three outputs, for long distance teleprinter link operation.
