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 92 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 environments3 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
