Later 857 and all 857D had the DSP built in from the factory so there is
no option to install one.? If the DSP options (like DSP BPF WIDTH/CUTOFF
etc) work you already have the filter.

Press the DSP button on the top of the radio. Activate DNR by pressing
the A/DNR key.
Press and hold the A key for one second tor recall DSP NR Level.
Adjust the DNR level and you should be able to hear a difference.

You could also use Key C to enable Band pass Filter and See "DSP
BANDPASS FILTER (DBF)" section in your manual for adjusting the cutoff
frequencies.

I'd like to add... Are you sure you got a North American 857?

I have an early 857D, I recall that for a few months back then someone was selling 857's at a ridiculously low price, it turned out that they were 857's aimed at Japanese noise hams and were only 10 watts of RF.

I'm pretty sure it's a US unit.
