It is suitable to be used in SSB mode. Under SSB, the noise is reduced, the voice identifiability is increased, and there is no obvious tone change. The chip element with 1% accuracy of capacitance and resistance is used in this module. after long-term use test, the filter works stably and the effect is obvious.
The net weight of the product is 8g.
Installation method:
Turn off the machine power, open the machine cover, you can see two filter installation bits (817 is one), one side is a 4-bit pin, the other side is a 3-bit pin, you can insert the filter according to the pin alignment.
