Informazioni

1. Versatility The IC-505 accepts either standard dry cell pack or optional rechargeable nickel-cadmium battery pack, IC-BP10, as well as external 13.8V DC Power Supply. Output power can be selected between 10W for fixed use and 3W for portable use, increasing its versatility. 2. Highest Receiver performance RF Amplifier dual-gate MOS FET (3SK74)—featuring ultra high gain and low noise—with PLL-circuit control voltage added to band-pass filter provide theoretically flat and optimum sensitivity. Moreover, high-performance crystal filter at IF stage assures ideal pass-band characteristics. 3. Distortion-free radio Transmitter The advanced circuit configurations including exclusive purpose IC’s in the balanced modulator circuit, double-balanced mixer in transmission mixer circuit, and a number of quality-assured band-pass filters and low-pass filters generate a pure signal with minimum spurious. 4. Microprocessor frequency control functions The Dual VFO system and 1 MHz UP function have been developed utilizing highly advanced computer and PLL technology. The IC-505 features 6-channel memories which can be used independent of emission modes, unique CALL channel, Memory Scan which sequentially searches memory channels, Program Scan which searches only specified frequency band, and other useful frequency control functions. 5. New liquid-crystal display panel provides clear visibility in sunlight. At night, simply turn on the switch for illumination 6. Helpful accessory circuits provide quick action Standard accessory circuits such as a split switch for split frequency QSO, noise blanker circuit which eliminates pulse noise, squelch circuit which functions even in SSB CW modes, dial-lock switch, and CW break-in circuit make the IC-505 the finest set for the amateur radio operator.
