VoiceMax is really gaining momentum!
Radio operators all over the world are enjoying the Voicemax
advantage.
Since VoiceMax doesn't use audio "clipping"... your audio is loud AND
clear.
What a concept!

The compression ratio of VoiceMax is fixed at 15:1 with distortion
levels well below 1%.
I suggest you read this for clarification... http://en.wikipedia.org/wiki/Audio_level_compression

RF Clipping is superior to audio compression in SSB transmission. RF
clipping will provide about 6dB improvement over audio compression
alone.

James is correct... that the RF clipping technique is somewhat more
effective. What he fails to mention is that it's more complex... and
not easily installed into an existing radio. RF clipping also
exihibits substantially more distortion. The VoiceMax installs
easily... and provides tangible results.

Actually as easy to design an RF Clipper as an audio compressor. True
it is a bit more difficult to install. Audio clippers can be external
to the transmitter and simpler to install and operate. A RF Clipper
will install as easily as your internal audio compressor.

Personally I would take RF clipping over Audio compression any day
with SSB transmissions. If the post filters are good in enough RF
clipping, there is not significant difference in distortion.

Correct. An RF clipper an be inserted after the SSB filters or before.
There are versions that do the clipping after the balance modualtor
and before filters. Sherwood did a RF clipper for the Drake TR4 that
was after the SSB filters and had crystal filters to restore the
original bandwidth.

Generally RF clipping is a bit more expensive than audio compression.
Then you get what you pay for.

I thought that there were some stand-alone RF clippers. Surely there is
no reason why they cannot be external units, inserted in-line between
the mic and the mic socket (ie audio in - audio out)?

Obviously they have to contain 'all the works' (oscillator, balanced
modulator, compressor, clipper, filters, balanced demodulator etc), but
at least they are self-contained and universal.

Regarding filtering, the main advantage of RF clippers is that they
eliminate the effects of second-order distortion, and only have the
distortion produced by in-band third order intermodulation. For
cheapness and simplicity, if you leave out the SSB filtering (ie do
everything at DSB), you will have at least twice the number of in-band
IM products. But how much worse is this than having SSB filtering?

They had a lot of company, and the residents here have a very short memory.
Datong was second. Comdel made an RF clipper in the late 60's and early
70's. Mike input and amplifier, mixed up to 455 KHz, sideband generated,
clipped the hell out of it, filtered it with a second filter, mixed back
down to audio with the same LO for injection to your mike input jack. Every
serious contester and DXer had one. Cost more than the receiver.

Why do you think that they only work on SSB? Stand-alone RF clippers
like the Datong are independent of transmit mode. They are audio in -
audio out (with a bit of RF magic in between). They should work even on
an audio PA system.

DF4ZS developed a RF speech clipper that fits into the Yaesu MH-31
microphone shell. This mic is used with the popular, tiny FT-817
transceiver along with others and in all speech modes. His clipper has
a SSB IF.

Details: http://jwm.de/afu/0ft817eng.htm
Reviews: http://www.eham.net/reviews/detail/2732 (6)

There are no reviews of the VoiceMax on eham.net while there are 21 of
the W4RT Electronics "One Big Punch" which uses a similar IC and can
be installed either in the MH-31 or inside the case of the FT-817 et
al.

DF4ZS also makes an outboard RF Clipper with adjustable a.f.
compression and integrated noise gate.

If you don't mind tying up a computer to do your speech processing,
VE3NEA developed freeware to work with a soundcard between the mic and
the transmitter that functions as bandpass filter, 7-band equalizer,
noise gate, compressor, and RF envelope clipper. http://www.dxatlas.com/VShaper/

This DF4ZS is a clipping type processor... nothing like the VoiceMax
audio compressor. You are correct, Since VoiceMax is a new product and
there are only about 150 units in use worldwide... so far there are no
reviews on Eham. Thanks for your interesting comments.

That is true. SSB RF clipping is proven to deliver an honest 6 dB
improvement.
