The all-solid-state FT-7B mobile transceiver provides high performance on the 80 through 10 meter bands. The operator may select upper or lower sideband (USB, LSB), AM, or CW operation, and the compact package contains many features engineered for maximum convenience during mobile operation. The TUNE control provides single-knob peaking of all transceiver circuits, thus eliminating inconvenient plate and load controls. Transmitter final amplifier input power is adjustable, up to a level of 100 watts. A high performance noise blanker minimizes impulse-type noise such as that found in mobile applications. Also built-in are a 100 kHz crystal calibrator and receiver offset tuning (clarifier). For CW operation, an audio peak filter plus semibreak-in with sidetone are provided. The receiver front end utilizes MOS FET and Schottky diode circuitry for maximum sensitivity and immunity from overload. The FT-7B operates directly from a 13.5 VDC power source. For base station operation, the FP-12 power supply may be used to provide the necessary voltage. In order to derive the maximum satisfaction from your new FT-7B, we recommend that you read this instruction manual carefully, so as to understand fully the functions of the controls and switches. The YC-7B outboard digital frequency display unit is an available option for your FT-7B, providing versatile digital readout of your .operating frequency. The YC-7B may be situated on the dash board, steering column, or other convenient location, for maximum visibility and driving safety.
