It is a metal-cased receiver with a polymer front and it is suitable for reception in the AM, FM, CW and SSB modes. Its frequency coverage is from 150 kHz – 30.0 MHz continuously in 30 switchable band segments. Its frequency readout is available in a traditional analog (dish) mode as well as in a digital display mode. Called a “budget receiver”, the FRG-7700 was released in 1978 as successor to the FRG-7000 and priced at approximately US$450. This type was in production until 1982. The FRG-7700 is a superheterodyne type receiver going up to 48 MHz in the Intermediate Frequency trap, followed by a fully synthesized local oscillators in the 1st and 2nd mixer unit and thus creating a VFO that is reasonably stable after warm-up.
