What happened to the Telstar Electronics SkyWave 2879ABTC CB Amplifier? IT WAS GARBAGE TOO!

Telstar Electronics VoiceMax IS GARBAGE!
 

I conclude that the VOICEMAX issue has died, has had the funeral and now should
be buried.

Those who advocate high distortion levels and poor quality signals can spend
their $$$ and buy it.

Those who prefer low distortion and clean sounding signals won't.

Let the trip to the cemetery begin.

We know, it has been ripped apart on this newsgroup a few times. It's not
a good product. If fitted without using the correct alignment procedures
and test equipment it will ruin performance and cause splattering over the
bands and generate harmonics. Not many people who have the "really loud =
really far" mentality will know how to use test equipment, they tend to be
the ones with a lack of knowledge. Maybe the type who believe polishing
the aerial will lower the VSWR!
The circuit has no RF filtering for a start, it is not screened in any
way, it has a light that you will never see once the radio is put back
together and it will have no benefit over the microphone that was designed
to operate with the radio. It will cause distortion and harmonics unless
the radio is realigned using test gear. If you use that on AM/SSB you
will sound terrible, it is a waste of time. There is no way that the
circuit differentiates between a voice and background noises, so raising
the level many times and keeping it at 100% will mean that the sound will
just be a "noise". Compare that to a normal mic, audio nearer to it such
as the operator voice will be louder than what is in the background.
The product is out of date, has no market and probably would have been
better 20+ years ago.

I certainly wouldn't recommend it, from a radio engineers point of view.





Just like so called Engineers, your a dumb ass John.
Your are an Engineer? What a Trash truck radio Engineer?

There is a noise gate built in. Read his Good web site.
Just wondered on what happened to the Power amp He had.

Thanks for your conclusion. Maybe you should contact the engineers at
Analog Devices and explain to them that their SSM2166 chip is just
plain no good. I'm sure they'd be happy to hear from you... lol

Deek if you run a 300 or 1000, or 3000 Hz signal into a good compressor,
since the circuit its only a controlled gain amp, the sinewave will come
out not distorted.

Simple test. Use a dual channel oscilloscope.

Display the input signal on one channel.

Display the output signal on the other.

Normalize the gain at one frequency, and don't touch the gain for the duration
of the test.

Adjust both traces to overlap each other.

Insert a swept frequency audio signal into the device. If the two traces are not
identical, the circuit introduces DISTORTION.

A brief course in Fourier transforms will convince you that a distorted sine
wave signal is still a series of sine waves, the fundamental, the 2nd, 3rd, 4th
harmonic, etc. The existence of those harmonics is by definition DISTORTION.

Your choice of expletives indicates either: you are losing the discussion and
have decided to shout louder; or, you are still in need of further intellectual
development. I recommend you spend 4 or 5 years earning an EE degree from an
accredited university.

You may desire distortion for some purpose, but it is still distortion.

I'm sure they will acknowledge that it introduces controlled distortion.

I'm surprised at you... being a chief engineer and all... you should
realize that in this audio application we're talking strictly about
harmonic distortion. After all, that's what you can hear. In the
Analog Devices datasheet (page2)... this is given for the SSM2166 as
"Total Harmonic Distortion including internal chip noise" of typical
0.25%... and a maximum of 0.5%. These figures rival the finest audio
equipment!

That said, you seem to know little more about the subject than does
he.
BTW, to see the performance of this thing without the hype:

Wes, I'm curious... what is this "hype" you are talking about? I would
like to address that directly.


First why don't you address the spam marketing part?

Then you can simply look the word "hype" up in a dictionary. It's a
simple word with a more precise meaning than "fuzzy audio", for
example.

So a bandpass filter for example is a distortion generator? Better
tip off all of those BC stations and recording studios that are using
equalizers.

I see. So a perfect sine wave run through a perfect clipper will
generate a 2nd harmonic?

OK... just as I suspected... you have no legitimate concern.
