Description: This is the similar amplified module they sell in other forms, but installed in a small module designed to be placed in-line with your speaker output. It is essentially portable, though requires power to run. Convenient to swap in and out of the shack and your mobile.

Almost unbelievable!
|
Time owned: 0 to 3 months
|
|
After seeing all of the great reviews of the Noise Away module,I purchased one from W4RT and received it promptly. The unit was small and compact and connected into my radio setup easily. I took the advice of one of the other reviewers and set the input and output levels according to the BHI online instructions, which were, I believe, in the manuals section. The results were almost unbelievable. I tuned in on any weak SSB voice signal that I could find and pushed the DSP on button. Almost like magic, the background noise disappeared and only the voice remained. Again like most of the reviewers suggested, a setting of around 5 or 6 was the right amount of processing. Over and over I tried this on different weak signals and got the same great results. One area of improvement is the included instructions are pretty sketchy and one needs to go to the BHI website to learn how to properly setup your unit for processing steps of 4 or 8 and input/output levels. Under very high noise levels, a very very slight amount of processing noise can be heard on the voice but is not at all any problem. All in all, I love this unit and would recommend it to anyone who gets tired of irritating background noise. The price was very reasonable at around $180.00. 73s Lon A.

Update to my original review
|
Time owned: more than 12 months
|
I first met one of these adaptive AF DSP modules in the version designed to be built into a radio. A friend had it and as soon as I got a demo of it, I knew I had to have one.
A lot of demo links for products are exaggerated or done under ideal conditions. This link here I can tell you is exactly what you can expect. Just play the sample .wav files. They speak for themselves.

I don't work anything but voice modes at this time so I can't give feedback beyond that. However for ragchew or nets, this thing is just ideal. It knocks the background hash down so that it is listenable for hours.
I have an older Kenwood TS-680S which has pretty much nothing for noise reduction or filtering so this is an invaluable add-on to this era of rig.
I should also mention that there are 8 levels of noise reduction, so finding the right balance is easy. You cycle through the levels, in half a second or so it samples the signal and 'settles' in. Fantastic.
I wanted to add that this thing is still working just great and the one big tip I can give with any of these active DSP units from BHI is that you have to adjust the gain staging for the input and output levels to get the most benefit.
You need to set the input drive level so that you are feeding quite a lot of signal from the source and adjust right to the clipping level. If you don't feed enough signal the DSP won't have as much data to analyze and won't be as effective.
If you take the time to fiddle just a bit with the internal pots, you can balance the input and output levels so that there isn't a drastic overall volume difference when you bypass the unit too.
This adjustment will vary a bit if you move this between rigs as the drive level on the audio outputs varies quite a lot at times.
With an older rig, this one piece will extend the usefulness remarkably. You may be surprised at how good your old rig is, all over again.

Excellent AF DSP
|
Time owned: 6 to 12 months
|
After having chat on the 20m with w2aji Mike he is the one who inform me regarding this AF DSP BY BHI (ANEM) after listening on the online demo @ the bhi web site.I decided to purchase for my Icom SP20 speaker.
I got mine @ w4rt a kit version Installed in Icom SP20 External Speaker this is a best addition to the my speaker. What you hear in Demo is what you will hear in the actual. It remove the white noise on the received & you will hear pure audio out of the speaker. My FT-1000mp Mark V Field w/ w2aji mod on roofing filter installed. This make a wonderful or best Transceiver ever had. Note use this also on my remote hf audio received link and it works great.

Update--Use with Mk V Menu 9-
|
Time owned: more than 12 months
|
My Anem is still going strong. As an update, for the Ft1000MkV, I access menu 9-1 and turn the internal receiver amp setting up to 31 or so(as high as possible--- think its about 20 from the factory). The ANEM brings the noise right back down but not the increased voice signal level.
After 18 months, I use it almost every time on the air and love it.

great after fix
|
Time owned: 3 to 6 months
|
I got mine from W4RT. The only nit I have to pick is the 2 jacks. They were auful in my unit and I replaced them with 2 radio shack mono jacks. The rating would be 3 before the fix and 5 afterword.
I use this unit with an Omni VII and it takes away any leftover hiss out of the signal making listening a pleasure.

Simply fantastic!
|
Time owned: 6 to 12 months

Put this in-line between my TS850SAT & the matching SP-31 speaker.
The best piece of peripheral kit I've ever had the good sense to get a hold of, simply superb & can't praise it enough.
For those of us not using DSP rigs it's worth every penny you'll pay for it.

After a month of use
|
Time owned: 0 to 3 months
|
I upgraded this to a 5. I did this because as funky as the 1-8 level control is, I never use it. I set it at 5, which works for me. I suppose I could clean up my desk a little by mounting it inside my speaker, but I may want to change my speaker someday. You have this option because the connectors and switches are not mounted on the pcb. This device should be left powered up. Otherwise, you need to turn it on each time you turn on your rig.
Again, this adaptive noise reduction is a must have if you have $200 you can spend on an accessory.

Excellent addition to any Xcvr/Rcvr
|
Time owned: 0 to 3 months
|
I read the review of the ANEM in QST and also email its author, as well as researched internet posting about it. I have a FT1000MP Mark V. I have the roofing filter as well as the 2.1 KHz filters as well, and can pretty much close QRM out but that nasty hiss remains (unless the sig is >S7 and I can use the IPO; can't add both the roofing filters and INRAD hiss modification).
The ANEM takes the hiss out and improves the receive quality I can get! Its an external AF DSP which is simple: off/bypass/on; and DSP level setting (1-4 or 1-8). The radio S-meter may be a S6 with noise, but the speaker sounds like S1, and I can easily hear the S-5 voice. There is little affect on the voice quality, only the noise. I have not used in on CW, only HF SSB. This is much better that the NR capability in the Mark V.
The price is about $200. While its advertised from Gap, most dealers (AES, R&L, HRO, etc) have no idea what the product is. I could not reach Gap, found that W4RT had it advertsied and got mine from there. Excellent service, Barry emailed me with availability and pricing at 10PM Wednesday night, I ordered it Thursday and was using it Friday. I highly recommend W4RT---they made sure they had one while on the phone with me and opened the box to make sure it was all there---WOW! The units are hard to find right now in the US. Way to go W4RT Electronics!
I think that the ANEM would be a valuable addition to any Xcvr which does not have a good internal IF DSP and think its AF DSP is probaly better than other older DSP (internal or external) implementations. The only down side I found is that when switching functions which greatly affect the audio, the ANEM must recalibrate itself and so you'll get the hiss back for about a second before the ANEM takes over (when going out of Xmit back to rcv, or switching a rcv function like NB, EDSP, etc).
I chose to get this speakerless unit rather than than those with speakers so I could decide the size what I wanted it on. I am using two simple car speakers (unamplified) which look nice with the Mark V. (I have used the SP-8 and the ANEM would improve its perforamnce greatly).
