BHI NES10-2 Speaker - is it worth it?

The nice thing about the BHI NES10 speaker is that it's pretty good as just a plain speaker too. Switched off, it becomes just a standard extension speaker, switched on - and it's slightly pre-amplified, and then finally when switched to DSP mode, it cuts down a ton of background noise. Also you can use it inline to another speaker - if you maybe have something with a bit of quality to it. I have an old Pioneer speaker in the shack, and often I run the NES 10 to that.
Mine was second hand from Waters & Stanton - so I didn't feel the pain of parting with 100. That's a lot of money for it.... although they do work.

I have the BHI DSPKR on loan for a week to test ,its the 10w speaker with volume control on top & the button you press until you get the right stage of filtering.
We had a talk at our club last night by Bhi & he left this on loan with the club for testing, by various members ,I have first test of it.
Not convinced how good it will be for me yet ,it certainly cuts out a lot of noise ,but for the 139 it costs perhaps the money would be better spent on improving aerials, so the other station has more chance of hearing me.
Will carry on testing for the next week

So the other station in umbobongo land CAN hear you and he is calling you back and calling you back. You've got this horrible noise on the band, some horrible static crashes or QRM and you can't hear his weak reply.

What are you going to do then? ;)

He'll probably move from somewhere full of QRM like RG2 in Reading, and go and live in a place that's good for radio, like Norwich. Next question. :P







Sorry . . . :$ Couldn't resist it after all your woes of QRM at your QTH Chris

My bands have been pretty darn quiet as of late I thank you very much....

Still the speakers DO work and work well. The DSP on my 590 is much better than my 897 but the speaker is better still.

Ive just bought the NES10-2 MK3 direct from BHI, Ive had it 2 days now and so far its pretty good, ive done some tests with it and compared it to the FT857D i have that has DSP built in, and ive compared it to the TS870S that has DSP at the IF stage built in.

So far the NES10-2 MK3 seems better that the 870, the 870 when the DSP level is turned up to a usefull level makes the audio sound watery and swishy, when the NES10 is turned up to a simular level to combat the noise there isnt any real signs of the watery audio or swishy sound.

Against the FT857D is a simular result, when i turn up the DSP on the 857D it does work and there is a reduction in overall noise, But the audio is affected quite a lot also, the highs seem dull and muffled, This is not the case with the NES10, Although when turned up to maximum it does affect the audio and makes it unreadable, from factory its set at number 6 on the dial on the rear of the unit, ive tried all the settings and 6 seems to be the best overall, Its quite amazing to think that such a small box works better than the DSP thats built into the TS870.

ive also been doing some simple tests with the NES10 , not only with it just by judgeing it by ear, but ive also go it rigged up to the Oscilloscope so that you can actually SEE what its doing and how it affects the audio and removes the noise, for the money it is, its very good, i dare say the more expensive units from say timewave and the like are better, but there up in the 300-400 mark, so overall its a keeper for me.

I shall put a short video up on the Tube of my findings and tests including the footage from the oscilloscope.

Anyone inetersted in stand alone DSP software should try this, its good but it does tie up your PC.


http://hamsoft.ca/pages/dsp-filter.php


Click on DSPFIL ver. 1.11E and download the software.

It takes a bit of getting used to but it does, comb filters, notch filters, bandpass filters and more.

Glad you're getting on with yours okay.

It is shocking how good they are for the money.

I've used a fair chunk of software DSP and its all been gash compared to the BHI.

As I said earlier the DSP on the TS590 is very good, much better than the 897 BUT the BHI is still better.

If you've got big time QRM, the BHI will not perform miracles, but it'll certainly bring a back of the box signal out of the hash ;)

Oh indeed. Be under no illusion that this will work miricales for you if you have massive levels of noise.

I have managed to make a few noisy contacts with it. I couldn't make out what they was saying due to loud noises etc, switch the filter on and I could make a contact.

I s'pose with a decent headset I'd also have had similar results.

... and it's worth reminding people that when switched off, it's still a damned good sounding extension speaker in it's own right - considering the size. I've also run a pioneer hi-fi speaker through the jack socket... and that sounds great with the DSP turned on.
The downside is - it spoils you. You get used to the lack of 'hash' and then when you use other equipment you realise how noisy some of it is !
