DSP?

Do you need it? Only if you want to hear the weaker stations covered up by noise. I think Texas Instruments and Motorola worked on the technology together. Can't explain exactly how it works, but I think I can get close.
The demodulated signal is fed into the DSP circuits and the noise is discriminated from the audio and suppressed. DSP did not become very common until the patents expired from TI. They were trying license it in the same fashion as the old Dolby noise reduction was for the music and movie industry. CB radio manufacturers pockets weren't that deep and TI was too stingy to take less. Well that's what I was told way back when. I tried to verify and the engineers I dealt with could not be be found.
