Information

■ GENERAL COVERAGE The model FRG-7700 is a high-performance, all solid-state, communications Receiver designed to cover the low, medium and high-frequency spectrum from 0.15 MHz to 29.999 MHz. ■ ALL MODE CAPABILITY A unique feature of the FRG-7700 is its all mode capability—SSB (USB, LSB), CW, AM, and FM. The FM mode is especially useful when the FRG-7700 is teamed with a VHF Converter. ■ DIGITAL FREQUENCY/TIME DISPLAY The FRG-7700 digital display unit allows you to display the operating frequency or time. Just turn a knob for selection of the desired function. ■ TWELVE MEMORY CHANNELS (OPTION) WITH BACKUP As many as twelve memory channels may be programmed for instant return to a favorite station. The memory unit stores the entire frequency, which means you never have to change the bandswitch when switching channels. A backup feature is provided to hold the memory circuits when the FRG-7700 is turned off. ■ LSI CLOCK TIMER If you want to record a program, but have to be away from your station, the FRG-7700 will do it for you. The built-in digital quartz clock contains a timing feature that activates the Receiver and internal relay contacts. Set the time you want to start and stop recording, hook up your tape recorder, and your FRG-7700 will do the rest. ■ WIDE DYNAMIC RANGE The FRG-7700 is an up-conversion superheterodyne Receiver, incorporating a 48 MHz first IF. The up-conversion technique and the individual filter networks in the front end eliminate most image problems, allowing you to receive weak signals. A high"loss" JFET balanced mixer is utilized in the FRG-7700 to provide wide dynamic range for protection from cross modulation. ■ CONVENIENCE FEATURES Selectable AGC, memory fine tuning, DIM switch for dimming the digital display, advanced noise blanker, and a variable RF attenuator provide the convenience you need for efficient operation. The front panel controls and switches are arranged in a logical manner, so you won't have to fumble for a knob when you need it quickly.
