Information

1. 144/430 MHz, all mode (FM, SSB (USB, LSB), CW) Transceiver. • Microprocessor controlled VFO and full variety of auxiliary functions. • FM circuitry based on KENWOOD;s advanced technology and outstanding SSB quality. • Built-in VOX. • Built-in side tone and CW circuitry capable of semi break-in operation. • Easy-to-operate 1 band, 1 MHz VFO stops at 999.98 kHz or is continuously adjustable (endless system). 2. Built-in digital display that indicates operating frequency in all modes. • Digital display equipped with easy-to-read green phosphor tubes. • 7-digit digital display that directly reads down to 100 Hz. • Frequency indicator that reads out carrier positions when mode of operation is changed. • Indicates fixed channel (stores any given frequency) and call channel frequencies, besides VFO A and B frequencies. • Digital display indicates which VFO (A or B) is in use, fixed channel numbers (1 through 8). • The use of display select circuit turns off the 100 Hz digits in FM mode. 3. Dependable electrical and mechanical functions. • VFO frequencies are switchable in 2 speeds, SLOW (in 20 Hz steps) and FAST (in 200 Hz steps). • VFO knob equipped with variable torque mechanism. • Pushbutton band select switches (UP and DOWN) that shift up and shift down frequency between 144 MHz and 440 MHz in 12 bands at 1 MHz intervals. • Wide band design for both Transmitter and Receiver that eliminates the need for tuning the RF circuits. • Panel layout based on human engineering. • Full variety of indicating functions to check operating conditions (Pilot lamps: ON AIR, Hi/LOW (FM transmit), F-LOCK, RIT, SLOW/FAST, Back-up power ON/OFF). • Amplified type AGC and ALC circuits that maintain receive and transmit outputs at constant level without distortion. A multitude of auxiliary functions for more enjoyable operation. The use of RAM memory system microprocessor enables any given frequencies to be stored in or cleared from fixed channels (8 CH). Built-in back-up power circuit to keep data stored at all times. Built-in scan and search circuits. RIT circuit functions on VFO, fixed channels and call channel. Adoption of frequency lock circuit. KENWOOD's unique noise blanker (NB) circuit to eliminate pulse type noise. Equipped with two meters, one is an "S" meter (with RF/ALC selector) and the other is a center meter for use on FM. RF power HIGH/LOW selecting function provides convenience in transmission with local stations. Auxiliary (AUX) socket. Designed for fixed and mobile station services. AC/DC 2-way power operation. Equipped with a grip for carrying convenience. Sufficient AF output power (2.5W/412). Built-in large sized speaker (7.5 cm). External speaker connecting jack.
