All he can do is spin, no actual facts. |

Since you can't seem to grasp this idea, forget about even casually mentioning digital sequencing to you,,,,you'd win the pool!!! : ) I've been watching this topic with some interest. IMHO the only true method of SS is the direct sequencing method. Frequency hopping sort of "cheats" the concept of a wideband and barely distinguishable SS system. Direct sequence is also more secure than FH. Nonetheless, frequency hopping is considered spread spectrum in today's marketplace. As far as using SS on 11 meters, well...... First off, there are no commercial CB radios made with this technology. Even hams have been slow to embrace it. That's not to say that enterprising experimenters have not played with it on 11 meters. Utilizing cordless phones and transverters might yield satisfactory results. I'm sure there may be a few that have. But it's hardly in widespread use. Dave "Sandbagger" http://home.ptd.net/~n3cvj |

Dave "Sandbagger" http://home.ptd.net/~n3cvj Hello, Dave The problem would be SWR with the requisite bandwidth. Of course, if anyone has any of those old Heathkit Cantennas ![]() There is a thought. 1.1 to 1 SWR from something like zero to 30 MHz. Not bad somewhat above too; just add oil and turn on your amplifier LOL. Best regards from Rochester, NY Jim - cooking at 3 megabaud |

That's one of the preferred commercial antennas for SS on VHF/UHF. SWR isn't flat but it's low over a 10:1 range of spectrum. The only problem is the poor gain. I wonder if anyone has ever tried to build a phased discone array..... ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

Since you can't seem to grasp this idea, forget about even casually mentioning digital sequencing to you,,,,you'd win the pool!!! : ) I've been watching this topic with some interest. IMHO the only true method of SS is the direct sequencing method. Yea,,that's what i meant when I said "digital" sequencing. Frequency hopping sort of "cheats" the concept of a wideband and barely distinguishable SS system. Yea,,I guess it could be seen that way,,,but,,why couldn't the technology be programmed to hop "wider" (for lack of a better term at the moment)? Direct sequence is also more secure than FH. I'm not up on the latest encryption technique regrading this technology, but take your word for it. But,,,why would a direct sequence (definite pattern) be more secire than a random pattern? Nonetheless, frequency hopping is considered spread spectrum in today's marketplace. Yep it is. As far as using SS on 11 meters, well...... First off, there are no commercial CB radios made with this technology. I never said there was. I said the technology was there and blew a gasket in a certain poster's gray matter and now he is all wrapped up in himself blathering incoherently about a cb radio when I referred the freeband. Even hams have been slow to embrace it. That's not to say that enterprising experimenters have not played with it on 11 .meters. BINGO! Utilizing cordless phones and transverters might yield satisfactory results. I'm sure there may be a few that have. But it's hardly in widespread use. Agreed. Dave ."Sandbagger" n3cvj |
