A well designed (probably something telstar can't do) and properly
adjusted speech processor can boost the average signal some, but most
of the claims made are just hype. Most, if not all cbers will simply
crank the gain wide open because it makes the meter "swang" more so
they think they are getting a bigger signal, and I doubt they have a
clue as to what an oscilloscope is much less how to use one.- Hide quoted text -

Rob, if you understood this device at all you'd know that "cranking up
the gain" as you put it... is not possible. Only the limiting point
and noise gate have adjustment. As for you comment about "swang"...
that doesn't make any sense either. Since this speech processor holds
the modulation constant at 100%... actually there is no "swang" (that
must be a technical term of yours). You're doing well so far... lol

Who is Rob?

My 2p, I mean 2c.

The job of an audio processor is to increase the 'average level' level
of audio without changing the waveform. This can be done at both audio
and RF frequencies (RF speech processors are commonly found in many
ham transceivers).

However, even in the best processors a certain level of distortion is
generated. It's down to the designer and the user to keep this to a
minimum.

Yes, a scope is handy but I doubt your typical processor user would
know what to do with one.

Hi Jay, long time no speak. I hope your antennas are selling well.

How right you are Phil. The processor I have designed has about 0.4%
THD at 1KHz. As you know... this level of distortion is undetectable
to everyone but maybe a maestro... lol
Hope everything there is well...

...... at 0dB compression. Why did you leave that part out, Brian?

BTW, when does full production begin? I'm still waiting to buy one so
I can run it through the bench. And too bad about the dismal sales of
your non-linear linears..."LOL".

Frank,
I knew you'd show up sooner or later... to spout your rhetorical
nonsense.
You're right on schedule... lol

And it took you less than 20 minutes to reply. But you didn't answer
my question: When are they going into full production? Cause when I
order mine I don't want to wait several months for you to build it. So
do you have them built, in stock, and ready to ship?

He has attempted everything from turn signals to splatter boxes, and
modulators.

No market for any of it.

Frank... I asked you this before and never got a response. Why would
you want to spend your hard-earned money on a device that you believe
doesn't work? That makes absolutely no sense. Obviously, you know it
does function as advertised. Believe me... I don't need your money. In
fact... if I were to see you ordering one... I wouldn't sell it to
you.

You know why, Brian.

No, I don't. That's why I want to run it through the bench. The only
thing I'm sure that works is the noise gate, but I still don't see the
point since all it does is shut off the audio when you're not talking
to eliminate ambient noise. And it's that ambient noise that let's the
other guy know that you're still keyed up. A noise gate would make
your radio sound like a cheap speaker phone, or that crappy digital
voice from Comcast. Hey, here's an idea -- when you're done talking,
why not just unkey the mic?

That's ok, I have a few friends that will order it for me.

Well... I still don't know why you would want to bench test something
that you have said doesn't work from day one. But that aside... let's
talk about the significance of the noise gate. Your understanding of
the way the noise gate works is correct. When the audio falls below a
user-defined threshold... the audio mutes. If you stop to think that
the VoiceMax has very high gain in the AGC... you realize that any low-
level background sound will be greatly amplified... up to around
+60dB. Without the noise gate... the hissing and wind noise in the
background between words would be extremely distracting. The
background noise detracts intelligibility from the voice signal. This
blocking of background noise between words helps the vocal clarity of
the transmission. It's really quite effective .. and the audio quality
is excellent. It certainly doesn't sound like a cheap speakerphone.
The speakerphone is quite different as the the person is quite a
distance from the mic in that application. This does present a big
problem... since the S/N ratio in that appliaction is very poor.
That's why speakerphones sound hollow... due to room acoustics... and
many times are choppy on transmit/receive... because of the poor S/N
ratio... and therefore very critical threshold setting. So far there
are eight pre-production units in the field right now. I haven't had
one complaint or problem. I have two installed in both my Cobra19 and
Cobra25 using the stock mic on one... and the Astatic 636L on the
other. They both work like a million bucks. I have the audio of a
power mic... without all the background noise. In my book... that's
the best of both worlds. My on-air experiences so far in the past few
months have substantiated my beliefs that the clarity is enhanced. I
came to that conclusion knowing how much less I've had to repeat
transmissions.
