As I said. "Obviously they have to contain 'all the works' (oscillator,
balanced modulator, compressor, clipper, filters, balanced demodulator
etc)."

That sounds very complex and expensive all right.
Another problem I see is that they only work on SSB.
My customers insist on something small that fits inside the radio and
processes in all modes. The VoiceMax does that with less than 1% THD.
Can't build them fast enough to keep them in stock...

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.

OK, thanks for your input.

Berhinger has consumed that nitch now, especially with ESSB.

LOL... a unit like that (http://www.nu9n.com/deq2496.html) would cost
you at least $300. That's more than your whole station is worth!
Come on... you know how frugal hams & cbers are. Get real.

Dream on, Brian. You can't touch my ts870 for less than $1000, more like
$1200 if you can find one.

I'm hearing more and more voodoo audio these days so there are plenty of
stations running rack gear, try more listening and less spamming your junk.

You mean that old beat up one you got at the garage sale?
I didn't know you ever got that thing working since it was under water
and so rusty inside.
Kudos on your technician skills... fixing up that old dog.

What the hell are you smoking, Brian? I traded an ft-920 for this 870.

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.
