#Let's do something#DSP makes the radio circuit greatly simplified, and the peripheral parts used are much less than the traditional radio, in fact, I am used to the hot spray gun operation, and it is not so difficult to solder the chip, but try to minimize self-soldering, because the melting point of special solder is low, and when soldering, it is still not good for the body to absorb flux and solder smoke.
Some small brands of radios have fair prices, and after using DSP, the gap between them and big brands is actually between them. The former BT6622 only costs a few dozen yuan, and the effect is comparable to the machine of hundreds of yuan, which has been well received by enthusiasts, and the effect is better than the effect of hundreds of Sony radios, which is the power of scientific and technological progress. The disadvantage of BT6622 is that the machine itself is relatively small, the horn effect is more general, and there is no shuttle, and the dial always feels relatively simple.
There is also a recent enthusiast to buy the icebreaker full-band radio, the price and BT6622 also have a fight, dozens of yuan is the full band, this can be better than Desheng in the popularization of radio, R308, MS200 These are kind, R308 has no short wave, MS200 has no FM.
Although it is only a few dozen yuan, it is not ambiguous at all, and you can use 18650 lithium batteries.
Technology is always advancing, I remember ten years ago it cost me hundreds of yuan to buy a 320g hard drive, and now I actually bought a 500g hard drive for 20 yuan in the live broadcast room. Now, if you look at the present in 5 years, maybe you spend hundreds of hundreds of dollars to buy radios, and you will also feel that a lot of money is wasted on consumer electronics.
