VoiceMax has Arrived... Introductory Priced on Ebay
"Telstar Electronics" wrote in message ups.com... http://search.ebay.com/_W0QQsassZtel...QQfsooZ1QQrdZ0 Why are you showing the use of coax to connect the board ? That board has NO RF filtering and it is NOT shielded in any way. I can imagine what will happen when it is incorrectly installed in a radio or not shielded with a filtered supply and filtered input. It looks like a half finished design. The LED is of no use as that will be inside the radio and only indicates what the level is at the board - not what it is on the carrier from the radio. You will also need an oscilloscope to set it up correctly. I would also be interested in you telling me how you think the average home user can adjust FM deviation correctly without the use of a test set! I wouldn't bother buying one of those, most radios have a better circuit built in anyway, so having two in series would be of very little use and would distort the audio or cause extra power consumption in a handheld. The product is of no use! It would have been good in the 80's before the K40 and Protel mics were used on CBs. Current CBs and amateur equipment would not tolerate that circuit as the impedances are completely wrong too. You haven't researched and appear to have very little working AF/RF knowledge. |

Coax is certainly necessary... and the board is fully shielded. What do you think that tin plate is for? The rest of your comments show that you obviously have not read the installation manual. I suggest you do so at http://www.telstar-electronics.com/VoiceMax%20B.pdf Thanks for your comments. |

Isn't that something that would render the radio non-type accepted? And why are you using tin as a shield? Just needing clarification so the multitudes will know what they're getting. |

This AGC amplifier can have gains up to 60dB at low input levels. Without proper shielding... this amplifier would oscillate (squeal) like crazy. VoiceMax has a solid tin shield covering all electronic components... as well as a solid copper pour (shield) on the non-component side. Hope that answers your question. www.telstar-electronics.com |

Would this not be adversely affecting the legality of the now modified radio? Of course this question would be null and void if you were designing your kit for amateur scenarios. So how does it fly with the FCC? Regards, Jim |

Teddy Roosevelt once said:
"It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat."

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. |

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". www.telstar-electronics.com |

A m ore prudent design would be to spread the gain over several stages to reduce instabilities of a single stage. Also proper RF by passing and PCB layout can minimize stray pickup of weak RF fields. james |

Why Do You Need a Speech Processor for Your CB Radio?
Two-way radio communication relies on the modulation contained within the signal. Maintaining a high modulation level is crucial in providing the highest possible efficiency from any transmitter operating on AM, FM, or SSB modes. Two-way radios also rely on microphones that inherently change audio levels delivered to the transmitter. This causes transmitter modulation to fluctuate greatly depending on voice level and pitch. The average modulation of a typical voice signal is only about 40%. This low percentage applied to the transmitter, results in less than optimal transmission range. Other Processors Have a Problem... Other speech processors use a low-cost "audio clipping" approach to achieve compression. While this method is economical for the manufacturer, clipping distorts the original signal and sounds fuzzy on the air. What these types of audio processors gain in volume, they lose in voice intelligibility. VoiceMax is Different... VoiceMax uses a sophisticated AGC (Automatic Gain Control) circuit that installs inside your transceiver to hold the audio level constant, with less than 1% harmonic distortion. No "clipping" type processor can come close to this low distortion level. Whether you're whispering or shouting, VoiceMax holds your transceiver at 100% modulation allowing you to punch through heavy channel traffic without sacrificing voice clarity. VoiceMax incorporates a feature not offered on other processors. The adjustable noise gate allows the user to block unwanted ambient background sounds. This feature is especially helpful in mobile environments where wind and road noise can be an issue. VoiceMax works with your non-amplified dynamic microphone to give you tremendous audio punch without all the background noise associated with power microphones. www.telstar-electronics.com |
