I have been using the AmCom DSP speaker for quite some time now. I find it is a 
easy "transparent" solution to all kinds of noise problems, quite similar to 
the old "NR button" fix.
 It's not specifically adjustable to any any particular type of noise, but has 
a fantastic "blanket effect" on all types noise. The bit rate is slow enough 
where it doesn't have any adverse effects on a cw signal, but it blasts away 
a "tuner upper" or a BC station in fine form. Random white noise, static, 
birdies, hash... all gone. In fact, I've used it mobile, and been able to copy 
stations thru a S-9 power line noise level... judging the desired signal to be 
an S-3,or so.
 Best thing is, it costs about $150... as opposed to $400 with the ZX. Worse 
thing is, you'll have to add your own power on/ power off switch. It has 
a "function on/off", but the unit is allways drawing current regardless. The 
radio shack large red pushbutton fit nicely under the Function on/off with 
plenty of room insde the case for work. And I had to add a fuse. Seems funny 
that these two items were left off the production run, but then again, so does 
the fan on a Ten*Tec.
 This unit comes either in it's own speaker cabinet (with a pretty decent 
sounding speaker), or as a "base" unit with out a speaker, but smaller. I opted 
for the speaker, as I was planning on running it mobile, and needed a speaker 
anyway. Note, with the base unit you'll have to add a headphone jack in 
addition to the main power switch and the fuse, as it only has one audio out 
for running to a speaker. The mobile unit has a 1/8" out for headphones.

Just another option for your consideration... hope it served as useful info.
