In 1945, RCA replaced the AR-88 with the CR-88 which placed the Crystal Phasing control on the front panel and reduced the size of the RF Gain and AF Gain control knobs so all three controls would fit just below the tuning dial.

The CR-88A replaced the AR-88F in the diversity receivers.

RCA's AR-88 planning may have chronologically followed their AR-77 ham receiver but the AR-88 owes much of its design concept as a replacement for RCA's aging commercial-military receiver, the AR-60.

Shown to the right is the typical British ham, G5FA, with his AR-88D station receiver. AR-88s survived in Canada because the receivers were built in Montreal and during WWII remained in Canada for various needs there.

AR-88s survive in Russia because a large quantity were sent over as part of Lend-Lease in the later part of WWII (after the USSR became an Ally.) The receivers were used for both surveillance and communications during the war.

After the war ended, it is assumed that none were returned and it's unlikely that any were destroyed.

Additional receivers were produced at RCA facilities in Bloomington, Indiana and Montreal, Quebec, Canada.

Use of Majestic Radio and Television Company as a contractor during WWII production is possible, although this company is usually mistakenly identified as the Grigsby-Grunow Company (bankrupt in 1934.) - Most of the early AR-88 production was sent to Great Britain or Russia (and to a lesser extent China and France) during WWII through Lend-Lease and this accounts for the scarcity of the early versions of the receiver in the USA.
