After seeing one go on another forum for 65 and me thinking "damn, i missed it" I've noticed that BHI are selling them direct on ebay at the moment for 100 delivered.

I'm just wondering if anyone has any oppinions of them?

I think this chap is a member on here but cant think who...

Yes indeed, that's our very own CT Admin "OffPlanet"s YouTube Channel. Offplanet, Gary, is a big fan of the Bhi Speakers and speaks very highly of them.

You can also get in-line Bhi filters to use with any external speakers, rather than the one with built-in filtering. The only downside, as I understand it, is that those speakers have little tiny dip switches to change the settings, which canbe a fiddle. Once they're set-up then the idea is you leave it alone. But an in-line Filters allows easier modification of the settings to take account of varying conditions.#

You might also consider a second-hand TimeWave DSP Filter, which will do much the same thing as the Bhi SPeakers and Bhi Filters, or even the MFJ 784b "Brick Wall" filter, if you can find one at a reasonable price.

Cheers for that. I thought I recognised the voice. I think I recognise the voice of the person on the radio too ;)

I also rather like the idea of one of these http://www.radioworld.co.uk/catalog/mfj1026-active-antenna-30mhz-with-noise-canceller-p-4001.html
They sound like they'd be brilliant in my area but I've no idea if they'd actually be any good.

I'm trying to toss up the idea of buying a speaker or wait a while and put the extra speaker money towards a better HF rig as and when a job comes up.
I'm then thinking that if the speakers are as good as they appear to be, why not buy one anyway :D

Well, basically, the Bhi Speakers are simply a DSP filter, and your FT897 has DSP already. But I use a TimeWave DSP-9+ with the FT897 and with the Kenwood TS570 (both of which have on-board DSP) and in some situations the sound is much better with the radio DSP off and the stand-alone Timewave doing the processing, or sometimes it is best with a combination of radio DSP and the Timewave.

On top of the TimeWave DSP-9+, I've also got a VEK-841 Notch/Peak Filter, and a MFJ-616 "Speech Intelligibilty Enhancer" in line with the Filtered Kewood SP-230 Speaker. Sometimes the sound is best with them all OFF, or One or Two of the units ON, with various combinations and settings. "Noise", to me, is a variable thing so it helps to be able to tune around.

The MFJ1026 does have some excellent reviews, although I've not used one myself. As I understand it, its Big Claim is that it can make an excellent job of Killing one specific Local QRM source. So if there is something in particular near your QTH that is giving you 90% of your noise grief, the 1026 does sound like it might well be worth a try. If you buy a good one second-hand and it turns out that it cannot handle your particular problem, the chances are that you can resell it on Ebayy for about the same sort of money.... So your loss would probably only be listing fees and seller's fees. Got to be worth a try at that :)

I think my noise issues here are down to location and not a single point of interference so in that respect the 1026 will be pointless.

The DSP in the 897 in my opinion is almost completely useless and it really doesnt do a very good job.

The more i look at it the more i want one of those tiny BHI speakers. The reviews do sing its praises very well and it is a nice compact unit that'd go quite nicely on my desk.

My current speakers are a bit naff for radio use. they are a bit too boomy and more for dance music than radio use.

I just wish there was some simple but effective software DSP i could use.

The BHI is a tidy little speaker, I bought one secondhand and I'm very happy with it, it does a better job than the filtering on the FT847. If you can put up with it's small size and small dip switches then you'll be a happy man. ;)

It stings a bit to pay 100 for a small speaker, but after it's been set-up right, it certainly does the business.

I did a more comprehensive review on this video BHI Video 2 Link

Works great on SSB, but I'm no fan of it on FM.

100 is a bit steep to pay knowing that one sold a few weeks back for 45 and one sold the other day for 65.

One shop has a second hand one for 80 and that takes the sting out a little bit knowing its not 3 figures.

I'm keeping my eyes peeled for one 2nd hand and I'll watch the 2nd video in a bit

Chris take a look on the BHI LTD site they also sell a retro fit dsp board
you can fit into your own radio or ext speaker
http://www.bhi-ltd.com
better option if you already have a good brand ext speaker

1) I can't do surface mount soldering. i'd destroy the radio!
2) I don't have a decent external speaker. its naff at best

but thanks

With a little bit of luck I think I've found one at a good price. I'll have to see how it pans out but if I do end up getting it I will post back with my findings!

There's a Mk3 version of the BHI speaker out now - the switches are now gone in favour of a rotary control.

Plus they've some other speakers listed now too.

I bought mine on ebay and works a treat on SSB. Coupled with the Maas it makes noise into voices. No complaints here

I often leave my radio on the 2m calling channel, fully opened squelch and the speaker on full DSP.

I can crank it right up and go downstairs and if a weak signal comes through I'll hear them calling and I wont need to listen to hours of SQhhhhhhshshshshshshshshshshsh

I had one and got rid of it after a couple of weeks. I found it very tiring to listen to and would rather hear the background noise.
There was just something, to do with the sound, I couldn't live with.
