The VoiceMax prototype field testing continues. There are no issues at
this time.
Several people have emailed me asking questions. Here are some of
those answers:
Currently installed in a Cobra19 DX4 with stock mic.
The VoiceMax module has been set on the prototype at a fixed 15:1
compression ratio.
The Cobra19's limiter pot has been adjusted so that the radio will
maintain a 95% modulation envelope from a whisper... to yelling into
the mic. (statement based on 2" distance from mic)
The "noise gate" has been adjusted to block all sounds below an input
level of 1mV from mic. At this level... and with the stock Cobra
mic... it blocks all tire noise in my vehicle.
Output of module has been adjusted to match the output of the stock
mic. (about 40mV @ 1KHz tone)
The power source for the module is derived from inside the radio and
is fully regulated. The current draw is around 15mA.
Attack time of the modules limiter is about 1mS. Decay time has been
designed to around 500mS.

I plan on starting an FAQ page out at the Telstar Electronics web site
based on these... and other questions I receive.
