I use the AmCom DSP "base" unit with my Omni VI/3, which also provides the
power for it.  This little DSP unit does a fantastic job of reducing the
very annoying background hiss to practically zero.  I have it driving either
an MFJ "Clear Speech" speaker or a Radio Shack "Minimus 0.5" speaker.  BTW -
the Minimus 0.5 speaker beats the socks off of any other commercially made
speaker I have ever tried for communications work.  The one that I have is
about 28 years old and unfortunately Radio Shack hasn't carried them for the
past couple of decades.

Noise Reduction 

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
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
stations thru a S-9 power line noise level... judging the desired signal to
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
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
for the speaker, as I was planning on running it mobile, and needed a
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.
