bovine excrement.

The board is not fully shielded. From the pictures I see components on
one side. If it were fully shielded then I should not see conponents
but some form of shielding.

What are you talking about?
The components are all under a metal shield...
The picture you see with all the components is before the shield goes
on.
I see you're still as sharp as a tack... lol
Now get your glasses this time and look again...

besides a well designed PCB layout and proper care in design can quite
often remove the need for shielding.

When you have an amplifier with 60dB of gain... and high local RF
fields... all the design and PCB layout work in the world will not
help you from instabilities... without a shield!

The main problem I see with the voicemax is that it is a fast response,
short hold time audio compressor.
CBers like their audio clipped off on their peaks so they can sound LOUD and
like ****. The more screwed up the audio is the better they like it

Now if the compressor was followed by a clipper with some clipping on the
peaks, followed by a low pass filter, it could sound LOUD without splitter.

I forgot CBers like to splitter across the band so their buddies on the
band can hear them no matter what channel their on.

like ****.

Capitalized for emphasis? :lol:

I know of two hams that have their audio cranked up so loud on
2 meter FM, that when you turn them down to a normal level, you
can't hear the reply from a normal user.

True, sounding bad is not exclusive to CBers... LOL
What do you mean normal level? 50% modualtion?, 70%?, 85%?
What is the modulation of a "normal user"?

You're right... CBers as a rule sound bad. I don't think they do this
on purpose... although you'd never know that by the way they carry-
on... LOL
You're also right that a clipping type compressor makes you sound very
distorted... and should not be used for voice applications.
After all... clipping type compressors are most commonly used as an
accessory for electric guitars... where they are commonly referred to
as "fuzz boxes".
