Yaesu FT-817/857/897 TCXO Temperature Compensation Crystal Module TCXO-9

Feature
1. The temperature-compensated crystal components applicable to Yaesu FT-817/857/897 models are fully compatible with the original TCXO-9
2. The frequency is 22.625MHz, which can improve the stability of the machine after replacing the original crystal. It performs better than the original module in different environments
3. In the actual test, the frequency of the crystal was observed with a high-precision frequency meter. The original crystal was roasted with a fire and the frequency immediately shifted, and the temperature-compensated crystal did not change significantly, and the effect was significant.
4. Generally, the temperature difference between winter and summer in northern areas is large. Many machines adjust the frequency in summer and deviate in winter, or if they are used indoors normally in winter, the frequency deviation can be solved by changing to this temperature compensation crystal. It does not mean that the machine frequency is not deviated and there is no need to change the temperature compensation. The temperature compensation is not used to correct the frequency deviation, but to ensure that the frequency of the machine is always the same under various temperature environments. Of course, many machines originally have frequency deviations replaced with this crystal. It was not biased immediately, it was because the crystal accuracy of the original machine was too poor and it was already biased.
Installation method
Turn off the power of the machine, open the top cover of the machine, and find the place where the temperature compensation crystal is installed. You need to unplug the crystal attached to the machine first, then align the pins and plug it in. After installation, you can start using it without any settings.
