Crazy idea?
Had an off-the-wall idea last night to use dbx noise reduction with a
CB. It would require dbx units on both ends. The audio bandwidth is small so Type I wouldn't work, but maybe Type II? Anybody ever try it? -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

DBX is 2:1:2 compression/decompression. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

It's a narrow bandwidth single sideband modulation technique which was first proposed when UPS was handed a 2 Mhz chunk of the 220 Mhz ham band. Dave "Sandbagger" |

I'll give it a shot this summer. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I tried a "crazy" idea years ago. Two commercial pitch transposers. Drop
frequency down and turn on a narrow filter. Voice quality is not super, but not bad and it used half of the bandwidth. Can cut qrm quite a bit.
