These hugely heavy and incredibly sensitive sets were, rumour has it, produced for Lend-Lease agreements with England for service in World War II. They are quite common in the UK but scarce in the US. There appear to be two 'flavours' of AR88 - the 'D' version has a frequency coverage as per above whilst the 'LF' version goes down all the way to 75kHz.
The receiver consists of two RF stages, a mixer, local oscillator, three IF stages, a detector, noise limiter, BFO, AF amplifier, output stage and power supply system. The IF amplifiers incorporate variable selectivity and a crystal filter. The sets are normally housed in steel cases but can be rack mounted.
The receivers are designed for coupling to a 200 ohm transmission line, except on low frequency general broadcast bands. For these and general use a single wire 25 to 50 ft. long can be used.
Estimating the value of a rig can be challenging. We collect prices paid by real hams over the years to help you estimate the value of a used RCA AR88LF. Just bought or sold this model? Let us know what you traded it for and help other ham operators!
