I actually started with that, but the US 2 meter "suggested" channels are
either 15 kHz or 20 kHz spacing depending on location. It's interesting to
dump all the 2 meter repeater traffic in my city to disk for several days.
Even the busy ones are only active about 2 hours/day. Unfortunately the 800
MHz public saftey band is so wide it's difficult to capture many channels,
and they are P25 anyway. I patched in the DSD P25 decoder, but it can only
handle two channels simultaneously. The public safety channel spacing may
work well with the pfb_channelizer.
Thanks,
