Temperature compensation crystal components suitable for models such as for Bazhong FT-817/857/897, fully compatible with the original TCXO-9 _x000D_ 2. The frequency is 22.625MHz, which can improve the stability of the machine by replacing the original crystal, and performs better than the original module in different environments _x000D_ 3. In actual testing, a high-precision frequency meter was used to observe the frequency of the crystal. The frequency of the original crystal shifted immediately after being heated, but the temperature compensated crystal did not show any significant changes, resulting in a significant effect _x000D_ 4. In general, there is a large temperature difference between winter and summer in northern regions. Many machines adjust their frequency in summer and then deviate in winter, or if indoor use is normal in winter, the frequency deviation can be solved by installing this temperature compensating crystal in the field. It's not that if the frequency of the machine is not biased, there is no need to replace the temperature compensation. Temperature compensation is not used to correct frequency deviation, but to ensure that the frequency of the machine is always consistent in various temperature environments. Of course, many machines have frequency deviation and immediately do not deviate after replacing this crystal. That's because the crystal accuracy of the original machine is too poor. If it is biased, the crystal accuracy can reach 0.5PPM, which is consistent with the parameters of the original TCXO-9 module, and the cost-effectiveness is extremely high _x000D_ Installation method: _x000D_ Turn off the power supply of the machine, open the upper cover of the machine, and find the location for installing the temperature compensation crystal. You need to first unplug the ordinary crystal on the machine, align it according to the pins, and then plug it in. After installation, you can start using it without any settings _x000D_ _x000D_ _x000D_ Note: _x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
