Clipping vs. Compressing
First of all, thanks for the participation on this thread!
In our discussion, we were comparing (mostly) the CBC-Dynamic Speech Processor (DSP) with the Telstar VoiceMax. As we may know, the DSP is a "clipping" processor and the VoiceMax a "compressing" processor (At first, I was "illiterate" of either processor or its method or theory of operation). Apparently, it is still debatable which processing technique is the "best" method of audio speech enhancement.
Although maybe a little biased, Lou Franklin (of CBC) wrote a paper explaining the difference in the four methods of speech processing, which I found to be very interesting and, for me, educational. Here's the link: All About Speech Processing for CB Radios .
For the fun of it, I'll "throw" a couple of other add-on processors in the "mix": The Top Gun Technologies (TGT) CP-1 compression module and the MD-1 modulator module. They are radio specific (not too "universal") and if both units are installed in those specific radios, it seems apparent that one could have the "best" of both "worlds" (clipping and compression)!
The newer Magnum radios, such as the OmegaForce S45, have both TGT modules factory installed. You have the option to turn them both on or off with one of the controls on the face of the rig. This radio is one of my newest "toys" and when I was trying it out on 10-meters with another ham friend of mine, He told me that there was a "big" difference (for the better) with the processing on as to it being off. We tried both AM and USB (didn't get around to FM).
I do now have the VoiceMax and DSP modules but still need to build the DSP from the kit. Don't think there is any way that these two (like TGT's modules) could be combined.
