Sharp Z-3000 Three-band Radio, also known as Sharp FY-73J, is a multi-function radio launched by the company in 1975. It has three bands: Frequency modulation, medium wave and short wave, among which the frequency range of the frequency modulation band is 76-90MHz, the frequency range of the medium wave is 530-1605KHz, and the short wave is 3.9-12MHz.
There is a white button on the upper left corner of the front case of the Sharp Z-3000 radio. It is the control key of the frequency dial lighting. Press and hold it and the lighting light will light up; once you let go, it will automatically pop up and the lighting will turn off. On the other side parallel to it is the model nameplate, and the "Z-3000" displayed in italics is particularly eye-catching. The rest of the front panel of
is a speaker guide grille for the speaker. This radio is equipped with two speakers, one large and one small, with a large speaker diameter of 10 cm, and the small speaker , that is, the diameter of the tweeter is 5 cm. In the position of the tweeter, a square sound guide grille was specially designed, which not only highlights the treble configuration, but also avoids the front panel being too monotonous and rigid.
0 The top of the body is the main functional control area. The round button in the upper left corner is the toggle keys for the radio function and the karaoke function. You read that right, this radio does have karaoke. A rectangular condenser microphone is built directly below this toggle key. When a company party, you can take out the hidden microphone and sing loudly.
The four black-body silver-top knobs are very eye-catching, from left to right, the microphone volume adjustment knob, the bass adjustment knob, the treble adjustment knob, and the volume adjustment knob. Below them are four up and down switches, from left to right, power switch , loudness switch (double as a short-wave beat frequency oscillator switch), mute switch, and frequency modulation automatic gain control switch. Note that this switch is dual-function, and it also serves as a medium-wave remote and local switching switch. A three-band switching switch is set on the right side of these four switches, with the frequency modulation band, short wave band and medium wave band respectively.
The black area on the top right of the body is slightly higher and lower, and the purpose is to facilitate users to view the content inside. To the left of this area is a signal strength indicator, which has another function that displays battery power. On the right is the frequency scale area of the green characters on the black background.
There is a buckle on the upper end of the left side of the body for mounting shoulder straps. There are 8 sockets below it, from top to bottom: NSB Crystal socket, microphone guitar socket, recording output socket, audio input socket, multi-out socket, timer socket, headphone socket and 6V external DC power socket. It is important to note: It is said that the first socket can be connected to accessories with the model NX-100, and I don’t know what it is for. If you know, please give me advice.
The upper end of the right side of the body is another buckle for mounting shoulder straps. Below it is a knob for tuning frequency. Interestingly, its side is not glossy, but has 6 slender rubber strips. When the user tunes the frequency, he can use his fingertips to press against these rubber strips to rotate. In fact, such a design requires a high level of tuning mechanism inside the machine. If damping is uneven or large, it is difficult to turn it with the fingertips against the side. Only smooth and silky tuning can be worthy of this design.
The top of the rear case is a pull rod antenna, and below it is a long sound guide grille. The lower left side of the grille is etched with a variety of information about the machine. The battery compartment is in the lower left corner of the rear case, and the Sharp Z-3000 is powered by 4 No. 2 batteries.
The entire machine size is 24×15×7 cm. When it was released that year, the price of this radio was 17,800 yen. According to the exchange rate of between the RMB and the Japanese yen in the 1970s, its price was equivalent to about 516 yuan at that time.
