Mush Reducer  Time owned: more than 12 months
Had the unit 4 years now and it drastically reduces local powerline mush to a level that makes the station much easier to listen to.
When something works then leave it alone and this one is stopping just where it is. Much much better than the dsp in the Mk5 and 756Pro I find.

Good Audio DSP  Time owned: 3 to 6 months
I purchased the NIR-10 used at an estate sale, in very good condition. I have the original receipt from the Ham Station; it sold new for $314.95.

I can only comment on Audio DSP, as I've never owned an IF DSP radio; but I'm told most people will not be able to hear the difference between Audio and IF DSP.

I whole heartedly recommend an Audio DSP for anyone who does not have good filtering on their receiver. The NIR-10 is just what the doctor ordered for older general coverage or Ham Band receivers without the the expensive ladder filters in the IF section.

The NIR-10 has a bypass switch which allows you to quickly change between modes; NIR (full DSP), Band Pass, and Bypass. You can instantly tell whether the NIR mode is useful; Or if the signal is better heard in the Band Pass mode. The unit has a three step BW switch which operates separately from the variable knob control. And it includes a built in amplifier that will power a very large speaker. (RCA jacks on the back) All powered from a 12v DC input (coax jack).

On the negative side; you must drive the NIR-10 with the correct audio level from the main radio. There's a PEAK LED that will flash on the high peaks of audio input, but you must adjust the volume control on the main radio first, then adjust the volume control on the NIR-10 for correct volume. Also, the purpose of Digital Signal Processing is to pick up the inherent peaks and dips of voice communication. That being said, the NIR mode does not work very well on music; You must switch to the Band Pass mode, select the Wide position from the BW switch, and adjust the knob for filtering.

Rescued my HW-101  Time owned: 0 to 3 months
Made a trade with a fellow who worked for JPS. He had this one stashed away and it was brand new in the box never opened. This was about a month ago, end of March 2000. Anyway, I had intended to use it with a recently acquired HW-101 to see how good I could make the 101 sound. For starters, the DSP functions very well and eliminates much of the noise as the 101 does not have a NB. But even better was the audio bandwidth function. Its as if you had a very good adjustable if in the 101. Now it performes nicely and brought the pleasure back to operating the HW-101 closer to todays standards. I give it a 5 because I think its great!
