The Heil Clear Speech Speaker arrived today and I got busy installing it. I
gave it a quick operational check then took it apart and photographed it
inside and out. I also scanned the Owner's Manual and created a pdf file
from it. I did have to add an Amidon core to the power lead and the signal
input lead since with 1KW I had RFI feedback. The cores resolved it 100%.

I am so very pleased and yes after the 746 Pro dopes all it can to reduce
noise the Heil Clear Speech Speaker can and does further reduce the audio
noise dramatically. I purposely tuned several weak and noisy stations on HF
and VHF and the dsp speaker did make an unworkable signal literally arm
chair copy..no kidding. Years ago I had the AmCom Clear Speech Base box on
my TS450 and it gave similar results. These things really do work.

Thank you for the review. I always wondered a little bit about those
speakers --- 73

Charlie,

I have a Am-Comm Clear Speech and find it indispensable for mobile
work. Do you see a significant difference between the Heil and
Am-Comm?

Tnx and 73,

Yes....the Heil has better sound and has adjustable levels of dsp although I
typically leave mine on the highest level. I like the headphone jack and
tone control neither of which my CS Base had.

All kidding aside... a digital speech processing app is an excellent idea.
However, you can get them for free (download off the internet!) Then, by
using either the line in (preferred) or mic input on the sound card of your
computer, and your computer speakers or sound card output--you can process
that audio to unfathomable depths!

I looked but could not find the dimensions for the ClearSpeech. I am
very tight for space and have the speaker on my mobile wish list

The pictures aren't any help as there is no reference point

ANy help would be appreciated

Thanks

My Am-Comm is 5.5"w x 4.5"h x 2.5"deep. I have it
mounted close to my ear velcro'ed to the rear
window in my GMC pickup.

Question -- got a buzz at this QTH; sounds like powerline hash; the
ordinary analogue noise-blankers on my Icom 735 and JRC NRD-525 will
take out the noise, but introduce heavy distortion on the received
signal. Will the the ClearSpeech digital doobies take out the noise
without distorting the signal?

Charlie,

Thanks for the review....I have one of the older versions...an AmCom
speaker/ DSP combo...and wanted to give my "unbiased" input.

The speaker does take out some noise but, unfortunatley I cannot give it the
same "unworkable to arm chair copy" review you have. I've used this with my
MP, MP Mark V and currently with my mobile FT100D. All experiences have been
the same; mediocre. There were few instances where the AmCom alone made a
signifcant difference.

The voice quality is very degraded when the DSP is engaged and the audio
level drops substantially and has a "talk in a barrel" quality. Having one
of the earlier models, I found the heavily engaged, non-variable DSP to be
quite annoying. Also, I found that the unit is definitely NOT required if
you use the internal DSP of the rig. Yaesu DSP and noise reduction are more
effective than the AmCom.

This is the second unit I've tried, having thought the first to be
defective. AmCom was nice enough to replace the first.

Additionally, I see you found out that the unit is RFI prone. Remarkable
that this should be the case for such as expensive accessory that is
supposed to be functional in an RF environment.

In short, Good Luck with the unit....and thanks for the review....

The manual recommends that you NOT use the same 12v power source
as the transceiver. How is that possible. You mean I have to buy another
switching power supply for my home rig and another battery for mobile?

What is your interpretation of this statement in the manual and how did
you connect it to a power source?

Hi Richard...
I do not use my Heil CSS mobile so my only application is as a base
station speaker. I purchased a Radio Shack 12v/500ma "wall wart" type power
cube. It works fine and cost about $17. I am using a Radio Shack 12v/500ma
(273-1773) adapter with the "H" (3.4MM)"adapta-plug".

Charlie,
 
This unit costs $210!....and now you have to power it externally........
 
And add torroids ...."Each Heil Clear Speech is tested in 1.5KW system and is guaranteed to be free of any RFI as it leaves the Heil assembly plant. ANY RFI problem encountered must be rectified by proper installation, use of correct toroid cores or ferrite beads." Doesn't make sense....is it RFI proof...marginaly RFI proof...or not?......
 
One would think that for a $200 devise, we could ask the manufacturer to make this thing RFI proof....

I believe what they're saying is that if you have a bunch of cables (audio, power, etc.) that are full of RF, they sufficiently block it internally such that it doesn't affect the sound coming out of the speaker.  However, there's really not much they can do to get rid of any RF on the cable insofar as it being picked up by _other_ equipment around your house, and it's here that one typically ends up with a bunch of ferrite cores around the cables as an attempt to reduce the RF on them.
 
I realize that $200 is a fair chunk of change for a lot of people, but I think it's quite reasonable considering what you're getting and the quantities they're likely producing them in.

Lou I can see your point but how can Bob foresee every installation? What
about the guy that places his Heil CSS on top of his AL-1500 and then
complains about feedback from this "no good over-priced speaker?"

Every Ham should already have a clean and neat cable system and effective RF
and electrical ground. And while I'm on my soap box...Radio Shack has 2
different ac power adapters that can power the CSS..and they range from
$15 - $17. If you can afford $210 for a speaker but can't go the $15-$17 for
the power source let me know..I'll send ya one! Sheesh...

It's not uncommon for many stores in the US to have large mark-ups on what are
really cheap accessories. For instance, in many of the big electronics
stores, you'll see USB cables for, e.g., $9.95 when they're more like a couple
of bucks mail order! This is something of a silly game, but given the
significant competition for the 'big ticket' items (computers, printers, TVs,
etc.), you can see why they do this.

Keep in mind that this is the same country where coffee shops selling lattes
for $3/cup are still multiplying like rabbits. :-)
