(Figure 1) is the powerport (in), which may be connected with 230V or 115V alternating current (AC) by use of standard three-pin plug (random configuration). Before use, please check if the voltage transfer switch (Figure 1) ⑪ is consistent with the alternating current (AC). When the voltage transfer switch is at 115V position, it can adapt to 110 - 120V/60HZ alternating current (AC); when the voltage is at 230V position, it can adapt to 220-240V/50HZ alternating current (AC); the switch’s factory setting is 230V (Note: only adjust under professional guidance)
Panel (Figure 2) ⑬ is the power switch and volume knob. By clockwise rotation, turn the power on, and by counterclockwise rotation, turn the power off. After power on, continue to rotate to the right to increase the volume to an appropriate location (the volume knob is normally adjusted to around ten o'clock direction). Due to the use of vacuum tube amplifier, vacuum tube needs about 30 seconds for warming up before normal operation. Therefore, the radio speaker will make a sound 30 seconds later. Note that the volume can’t be turned to the maximum during these moments.

Radio use
instructio
1
When the machine is used as a radio, it is of paramount importance to place the machine and the external antenna correctly. Otherwise, you may not receive any radio programs, or only receive bad one! It is recommended to use the machine close to window as much as possible. If it is impossible to use the machine near the window, a group of external antennas will be of great importance. The more professional the antenna and antenna installation, the better the machine performance. In addition, in case of connection with external antenna or not, it should also be noted that the switch position for internal/ external” antenna on the back of the machine must be correct!
Listen to FM broadcasting
This machine has equipped with built-in FM line. If the radio is placed close to the window in the general urban area (not far from the radio transmitting station), there is no need to use external antenna generally. When external antenna (random accessory) is used, turn the rear(Figure 1) to the external (EXTERNAL) position. The external antenna of this machine can also be connected with dedicated external antenna or dedicated cable antenna. Press the (Figure 2) ⑯ key switch on the front of the machine to be in FM wave, and adjust the tuning knob to the range of 87--108MHZ for its radio programs. Turn the transfer switch (Figure 2) ⑫ to FM position to be in ordinary FM state. Turn to FM St position to be in stereo FM state. If the FM St effect is not good enough, the switch can get a higher Signal to Noise Ratio (SNR) at FM

Radio knowledge
What is shortwave radio?
Many countries in the world use short frequency to perform worldwide broadcast transmission. Shortwave frequency range is usually between 1.6MHz and 30MHz. The radio that can receive the frequency with the range is called shortwave radio.
What is shortwave meter wave band
In general, we also divide the shortwave frequency into many "meter bands". Each meter band contains a frequency range. For example, the 19M band contains a frequency range from 15.100 to 15.600MHz. The International Radio Consultation Committee (CCIR) stipulates that the civil broadcaster uses the frequency within meter band range, and the frequency beyond meter band is mostly used for military and other civilian communications. Therefore, the civil broadcasting programs can only be received within the range of meter band frequency. (Please refer to the table below)

Effect of listening to shortwave programs at different times of the day
What language programs can be received by shortwave radios?
Shortwave signal propagation is subject to the influence of many factors, such as sunspot activity, atmosphere and earth-ionosphere change. The shortwave propagation effect varies with band, sometime good in the daytime or at night. It is not good to listen to shortwave program during daytime, especially from 10 am to 3 pm. It is mainly because that shortwave is greatly affected by the change of ionosphere in such period, leading to short transmission distance. If you want to listen to shortwave programs during the daytime, please refer to the table above. The effect may be good in certain meter bands, but inferior to that at night.
If in China, in shortwave radio programs, the Mandarin, English, French, German, Russian, Japanese, Hindi, Spanish, Portuguese, and other languages may be heard, as well as our Cantonese, Teochew dialect, Shanghai dialect, Minnan dialect and other dialects. China's Central People's Broadcasting Station also uses Mongolian, Uygur, Tibetan, Kazakh, Korean and other minority languages for short-wave radio broadcasting.
What kind of radio broadcasting can be received by shortwave radio?
What content in the shortwave program?
Is there the need to use outdoor external antenna to listen to shortwave radio broadcasting?
Most countries in the world have shortwave radio broadcasting. However, the shortwave radio station in a certain small country can only cover the territory of such country, owning to small transmitting power, which cannot be received well by our country. Even a station with strong power, the receiving effect depends on geographical location within or beyond coverage range. For example: some frequencies of China's Central People's Broadcasting Station shortwave radio broadcasting can be received well in our northeastern region, but badly in China's southwest region.
Thanks to the national cultural and political background of different countries, the shortwave radio content varies with country. In general, the international shortwave radio program contains world news, national news and local news, news reviews, national culture, music appreciation, language teaching, etc. Some countries even set up police information announcement, weather forecast, marine information forecast and other program. It must be stressed that the official radio station of each national government represents its political positions and economic interests. Therefore, when listening to international broadcasting, you should have ability to make judgment.
This depends on your listening environment. The reinforced structures will shield the broadcast signal. In some remote areas, mountains and mining areas, the shortwave signal will be slightly weak, so it is necessary to install the outdoor antenna.
Is the shortwave signal clear?
The effect of listening to shortwave broadcasting depends on the strength of radio transmitting power, the performance of radio and the receiving location and other environmental factors. With the improvement of radio technology, the listening effect will get better and better.
9
How to test the effect of an
external antenna?
Must the external antenna be very high and long?
In a general listening environment, turn the radio to a relatively weak shortwave radio station, and go outside of the room while listening. If the shortwave radio signal is enhanced, outdoor antenna should be installed to improve the receiving effect. However, if there is a strong TV station, FM radio, BP machine and other radio communication antenna near the receiving location, the strong interference signal will cause poor receiving effect of shortwave external antenna.
In short, shortwave external antenna will get better effect if it is high and long. But, higher and longer antenna doesnt imply better effect. Sometimes, sensitive antenna will introduce strong radio interference wave. Therefore, the height and length of the external antenna should be adjusted according to the actual needs.
11
FM broadcasting
FM (FM) is a close-range high-fidelity radio system, which is the broadcast system with most rapid development, the largest number, and best sound quality. In some developed countries, a city even has 30 FM radio stations. Since the 1980s, China has built a large number of FM radio stations, and almost all of them can play stereo programs. China FM radio frequency: 87 ~ 108 MHz, the frequency interval 0.1 MHz, radio frequency from several hundred watts to twenty kilowatts.
Special warning: do not install outdoor antenna in the multi-lightning area!
12
What signal will affect FM reception?
Powerful VHF TV radio broadcasting and personal computer switching power supply radio wave will interfere with the FM reception. In addition, the FM radio stations with adjacent frequency and strong transmitting power will interfere with each other, leading to poor reception effect.
13
How far is the receiving distance of the FM radio?
FM radio frequency is very high, and the radio is transmitted in a linear way. The higher the transmitting antenna, the greater the power, the larger the coverage, and the farther the transmission distance. FM radio transmission distance is usually 30 to 100 km.
14
How to reduce the interference of
FM?
Shorten the lever, change the direction of the antenna, change the listening position, and keep away from personal computer equipment, to
reduce the degree of interference.
16
Shortwave radio
Shortwave is transmitted mainly relying on the reflection and refraction between ionosphere and the ground, regardless of day and night. Shortwave can be transmitted very far, so the radio can listen to the long-range radio sound in shortwave band.
How to achieve long distance
listening of FM radio?
Use VHF outdoor TV antenna and antenna amplifier. Install the antenna as high as possible, align the antenna at the direction of the FM radio, and connect to the radiotelescopic antenna with 75 ohm coaxial cable, so that the receiving capacity can be greatly improved. Some cities have used cable television networks to transmit cable FM programs. Attempt may be made to pull the antenna from a cable jack.
Shortwave frequency is between 2 and 30 MHz, and is divided into civilian broadcasting meter band and communication dedicated band. Civil broadcast use amplitude modulation system and shortwave communication typically uses single sideband (SSB) system.
Why does the shortwave radio sound
suddenly rise or decline?
The ionosphere that propagates the shortwave is unstable, because its thickness, height and ionospheric density change at any time, especially during daytime. The shortwave signal arriving at the radio is sometimes strong or weak. Therefore, when listening to shortwave broadcasting, the sound may suddenly rise or decline. This phenomenon may be mitigated for the radio with good automatic gain control <AGC> performance.
Medium wave broadcasting
Medium wave is the world's first and most widely used folk broadcasting band, which is mainly applied in domestic, provincial and municipal, regional and other medium-distance radio, and has rich programs. Wave broadcast characteristics: short range during daytime, and long distance during night, easy to suffer from the interference from lightning and household appliances. China medium wave broadcast frequency: 525~1610kHz, step length 9kHz.
19
Why more radio stations received at night than that of the daytime?
Medium wave propagation mainly relies on the ground wave. Only a small amount of medium wave is transmitted by relying on sky wave.
When a radio wave encounters conductor, conductor will generate induced current, consuming a portion of energy. The phenomenon that weakens the radio wave energy is called the absorption of radio wave.
The ground is a conductor, which has high absorption of medium wave. So, the medium wave cannot be transmitted for a long distance in the form of ground wave (about two or three hundred kilometers).
Due to sunlight and ionization density increase during the daytime, the ionosphere becomes a good conductor, such that a small part of the medium waves propagated in the form of sky wave will be strongly absorbed, and difficult to return to the ground. Moreover, the medium waves propagated in the form of ground wave are absorbed by the earth and cant be transmitted for a long distance. So it is difficult to receive the medium wave radio stations during the daytime.
At night, the atmosphere is not subject to sunlight, and the mutual recombination of ionospheric electrons and ions is significantly increased. Hence, the ionosphere becomes thinner, the density becomes smaller, the conductivity becomes poorer, and the radio wave absorption is also greatly weakened. At this time, the medium wave can be transmitted to a remote place through sky wave, so the more medium wave radio stations could be received at night.
20
What factor will affect broadcasting reception effect?
The reception environment is the main factor that affects the broadcast reception!
In the receiving environment in modern city, there are many waves that may interfere with the radio, such as FM radio, wireless phone, personal computer switching power supply and powerful shortwave SSB communication station. It is very difficult to listen to shortwave programs near such places; furthermore, various motors, cars, televisions, microwave ovens, SCR equipment, and the fluorescent lamps and poor quality energy-saving lamps that use electronic rectifier will seriously affect the medium wave broadcasting.
The mutual interference of a large number of FM radio stations and VHF TV will also make the FM radio receiver worse. The second problem may be the radio itself.
