NXDN48 Voice Decoding is Good Now
Just use squelch if using SDR++ or GQRX to feed it. RTL-SDR input mode and NXDN still makes tons of false positives, and doesn't work well at all. May just be a bad signal issue but still think the RTLSDR input uses wrong center freq/tuned freq/"optimizations", need to get back to that some time, maybe also implement squelch settings on rtl_fm mode.
Thanks to LouisErigHerve for his 'Improved NXDN Detection' update on his version, implemented it and works SO MUCH BETTER!
May still disable the if ((state->lastsynctype == 9) || (state->lastsynctype == 17)) condition in dsd_frame_sync.c if I think it leads to more consistent decoding vs false positives. USE SQUELCH!
