 =====Filter replacement=====
-The radio is set up to receive +-5KHz FM voice, but on packet we're using +-2.5KHz deviation. I replaced the second IF filter (CFW455F, -6dB BW +-6KHz, -40dB BW +-12.5KHz) with a tighter filter (CFW455H, -6dB BW +-3KHz, -40dB BW +-9KHz).

I replaced the second IF filter (CFW455F, -6dB BW +-6KHz, -40dB BW +-12.5KHz) with a tighter filter (CFW455G, -6dB BW +-4.5KHz, -40dB BW +-10KHz). I have an even tighter one which I may chuck in down the road (CFW455H, -6dB BW +-3KHz, -40dB BW +-9KHz).
