You might consider a DSP speaker or filter.Had my 7300 for a while now and so far I've been disappointed in the NR ability. I'm in a very noisy environment and when I get the radio to a point of reducing the noise, the signal is unintelligible. While my Yaesu FT891 is less sensitive I believe that it's noise reduction capability while leaving the signal understandable is better.

That's a lot of radio for a great price.
