[Strong compatibility]:For Yaesu FT-817/857/897 and other models for temperature-compensated crystal components, fully compatible with the original TCXO-9.
[Strong compatibility]:For Yaesu FT-817/857/897 and other models for temperature-compensated crystal components, fully compatible with the original TCXO-9.
[High stability]:he frequency is 22.625MHz, which can improve the stability of the machine after replacing the original crystal. It is superior to the original module in different environments.
[High cost performance]:The price is only 15% of the original module, and the cost performance is extremely high.
[Effect is remarkable]:Actual test the frequency of the crystal is observed with a high-precision frequency meter. The original crystal frequency is deflected with a fire-baked , but this temperature-compensated crystal has no obvious change, and the effect is remarkable.
[Simple operation]:Turn off the power of the machine, open the cover of the machine, find the position where the temperature compensation crystal is installed. You need to unplug the ordinary crystal of the machine, then insert it according to the stitching of the machine. After installation, you can start using it without any settings.
