My one stop solution for noise reduction Time Owned: more than 12 months.
I own a small fleet of BHI products, all of which are fantastic!
I agree with everyone's remarks from good to bad but my experience pushes me in the direction that not all audio sources are created equal. The same BHI solution that works great on one radio is quite useless on another.
I believe that it has to do with impedance matching as when I use the same BHI product on a radio that has both speaker and headphone outputs, it always sounds better connected to the speaker output and not the headphone jack.
All in all all the hiss is gone and the voices magically appear as if you are listening to FM radio. Lightning crashes still can make it through though. 73 de AD0AR

Nice But Flawed by awkward control convenience Time Owned: 0 to 3 months.
Bought the latest version - NES10-2 Mk4 just recently. It replaced a module fitted to a Kenwood speaker, Both purchased approx. 15 years ago, The new Speaker works fine, particularly effective on local noisy ground wave signals. Removes all hiss etc. I don't find the sound distorted but it is a little punchier/harder than when using the speaker unprocessed. However, I find this an advantage and easier to listen to than with the processor off. My only gripe is with the ergonomics. Switches etc are small and fiddly and not easily accessible with the unit placed on a self slotted in amongst other gear. But I would thoroughly recommend it from my limited experience so far.

Poor listening quality Time Owned: 0 to 3 months.
Eliminates noise but the audio quality is very bad. Audio too unreal and distorted

Primo!!!! Time Owned: more than 12 months.
I originally got one of the MK1 models years ago.Now I have three of them.One at home,one in the mobile and the third for portable ops.

On the Minus side :-(
The audio out sounds abit crackly on peaks.
The unit exhibits a low audio hum.
Please bhi do away with the awful coaxial DC plug socket.Kindly wire in a permanent 'flying' DC wires.

The home base unit failed the other month.Some how I managed to blow the protection diode on the earth circuit.A Mk3 model has been ordered and is on the way from the UK :-)

Set up correctly these are absolutely brilliant
Over all I highly recommend them.

Points missed earlier Time Owned: 0 to 3 months.
Oops - I forgot, that there is a bypass switch for the noise cancelling stage, but it is in a forgettable place, underneath the unit, and hidden by the mounting bracket. Also, I should add that the hum is most objectionable (unbearable) when using headphones, especially at low volume.

Very good hear stations out of the noise. Time Owned: more than 12 months.
This noise cancelling speaker works well. While running a special event station from South Africa I managed to hear and work on 8 nights stations from Europe that were lost in the noise. I used this filter with a kenwood TS 50. This nose cancelling speaker seems to work very well with the TS 50 radio. It did not seem to work so well with and old Icom 735. I am not certain if I have mark one or mark two.

dee yes peeeeeee Time Owned: 0 to 3 months.
well i got this one for 100 pounds,well when i got it out of the box i thought i had been done.
it did not look like a hundred pounds worth and i thought well it will not work good by the look of it as it seemed very small.
Well i put it on and i was glad i was wrong it did work good cut the noise down, and was loud so i take my hat off to BHI..what a wonderful speaker.
It makes my yaesu ft 890 as good as the ft-950 and i dont need to get another radio.
I would recomend this speaker to anyone and yes its worth the 100 pounds hands down...jeff M6GLH

Good for satellites Time Owned: more than 12 months.
I have been using the unit for 5 years now, connected to the audio output of my Icom 821H and 910H satellite transceivers. The unit was designed primarily for white noise reduction and allows me to clearly receive satellite signals from the horizon upwards, instead of 10 degrees and above before I had the unit.
The only minor gripe is the small headphone socket on the side of the unit.

Earlier 5-star review posted by G3LGR on 2005-08-19

I have been using the NES 10-2 speaker on satellite work with my IC821H for about 18 months.
The DSP function totally outperforms my Timewave 599X, but the NES 10-2 does not have bandwidth filtering. The Timewave now supplements my HF gear.
On the plus side, I can pull out satellite traffic from all the LEO's (and AO40 when it was working) when I can only just hear that there is something there under the background noise.
I estimate that it provides me with about 10dB effective gain.
The miniature headphone socket on the side of the unit has also proved reliable
When on FM, with no signal and the squelch at minimum, the background noise hiss is very evident. Turn the DSP on and in 2-3 seconds it dies away to a whisper.
The only criticism I have is that the 12 volt power connector can make poor contact and I needed to 'glue' it in place for mobile use in my Diesel Landrover Dicovery.
I would recommend this unit to anyone wanting near total white noise removal from their radios.

almost unbelievable! Time Owned: more than 12 months.

I was talked into buying one of these years ago, (despite my reservations about it) and for various reasons never got around to hooking it up to anything. (long story). Now I am getting back into ham radio and dug out my old IC-756Pro2, and set up a makeshift antenna to check it out. I found some signals buried in the hash, and the built-in DSP in the Icom didn't seem to help much. Then I connected the NES10-2 (Not sure if it's Mk1 or Mk2) and was astounded at the result. The noise floor just disappeared! And there was the signal; it was as if I had replaced the antenna! Every ham (or short wave listener) should have one of these...
