Question 6: When was this radio? Is it valuable? How much is it worth? It's a Hongqi 502 medium-short wave five-tube transistor radio produced by Shanghai Radio No.3 Factory before 1967-1970, but according to the product label pattern, it seems to be a product after 1970. 1970 On April 24th, China successfully launched its first artificial earth satellite. The satellite runs well after launch, and all kinds of instruments work normally. The telemeter keeps sending back all kinds of data and playing the music of Dongfanghong circularly. That is the dominant communication equipment-radio, and of course, we should keep up with the situation to show pride and glorious propaganda. The picture shows red radio waves spreading all over the earth. Generally, flea markets range from 50 yuan to 200 yuan, and some of them are priced above 800 yuan. The product logo before 1970 is as follows, compared with the landlord.
Question 7: When did the word radio appear and what are its different names in other parts of China? The word radio appeared very early. Some people call it "drama box", "electric box", or simply "box", some people call it "radio" and some people call it "broadcast".
The radios in Manchukuo are all made in Japan, Sharp, Mark 3, Mark 4 and so on.
After liberation, the state removed all the "short wave" lines in the old radios, so that people did not need to listen to short waves and enemy stations.
Many cities in China produce radios, which is the largest electronic product industry in China.
The simplest radio is a crystal receiver. Listen with headphones without power supply.
Radio circuits are divided into direct amplification, regeneration, super-regeneration, heterodyne, superheterodyne and frequency modulation.
Advanced radios also include "adjustable high amplifier", "multistage intermediate frequency amplifier", "cathode output", "stereo" and "floor-standing".
There were many electron tube radios before the Cultural Revolution, and there were discrete transistor radios, printed circuit radios and integrated circuit radios before and after the Cultural Revolution.
Question 8: How to adjust the time of car radio? Different machines are slightly different, depending on whether you put them in the same car or added them later. The original car is synchronized with the time on the meter. General system time can be found in the system settings. See if there are any STEUP or system options on the interface, and go in and look for them. If not, send a picture to see what it looks like.
Question 9: Why are there no instructions for adjusting the radio time?
If you press a button, you can break it. Not bad.
Use your rusty brain. You can't even tune the radio. Just throw it away.
