#130 MPT-1327 Decoder Filter issue resolved. Converts the post-demodulation filter from a band pass filter to a low-pass filter with 60 dB attenuation and a cutoff of 3200 Hz. This is then followed by a high-pass filter at the decimated channel rate, internal to the decoder that performs DC removal and removes any CTCSS tones prior to the FSK decoder.
