Small LPF add on SMD board for earlier K3 DSP boards that adds a Low Pass Filter to roll off RX audio above 4 kHz. This is already included on the  Rev D and later Assembly K3 DSPs, which are included on all  K3S radios.   


(Requires making two PCB cuts and soldering the short LPF board connections to the DSP. )

All K3S radios ship with DSP boards that include this change.
