BOOST YOUR "TALK POWER" AND RANGE
Blow Their Ears Off With DYNAMIC SPEECH PROCESSING!
Ever wonder why those Rock ’N Roll radio stations always seem so loud? Or why TV commercials seem to be louder than the program itself? The reason is because smart broadcasters use exactly the same modulation processing that’s now yours in this simple add-on device. You won’t find this circuitry in the average radio; it would cost a lot more. And the sophisticated design requires too many parts to fit inside a power mike.
Your voice only modulates a transmitter about 30% on the average. So during a one-minute transmission, you’re really only hitting full RF power output for about 20 seconds; the other 40 seconds are wasted energy. Here’s why: almost all of the voice power is concentrated in the consonant sounds (B, K, S, etc.). The vowel sounds (A, E, I, O, U) contain very little average power and can cause high-intensity peaks which easily overmodulate a transmitter, causing channel splatter and "bleedover." Also, voice frequencies below 500 Hz and above 3000 Hz contain little power and don’t really improve voice communications. With our DYNAMIC SPEECH PROCESSOR, the unwanted frequencies are reduced while at the same time the high intensity peaks are "clipped off." The ’scope photos show how the DSP effectively raises the average power relative to the peak power. The result is a dramatic increase in perceived loudness by the listener, to about 90% average modula tion. Now you’re running at your full potential RF power output almost all the time! And the best part is that proper adjustment of the DSP output eliminates overmodulation and channel bleedover while letting your voice punch through LOUD!
FEATURES:
· dB
improvement (one S-unit) in AM/SSB audio power with little or no distortion.
Improves communications during heavy interference or weak-signal conditions.
· Prevents
overmodulation "bleedover" while maintaining extremely high average
modulation. Over 30 dB of dynamic range is compressed to modulation levels
averaging 90%, even when you whisper!
· Harmonic
and RC filtering assure clean, problem free audio signal.
· Powerful
IC design is equivalent of 15 transistors. Adjustable clipping and output
controls to match any situation or radio; works with any CB or HAM transceiver.
Jumper options to match any stock mike, power mike, high or low impedance.
· Simple installation.
Small size (3" x 2¼") fits easily inside radio. Connects
to mike wires. Powered by the radio’s own +12 VDC supply. (Only 15
mA current drain.) Includes instructions for separate box mounting if desired.
· Simple kit
construction. Completely illustrated, non-technical instructions. Use soldering
iron and common hand tools.
