SSB or Single Side Band?
Howdy! I've seen CB radios that have SSB as well. However, I don't
understand this very well. That is, what exactly can you do with SSB? How far does it reach out? What kind of license do you need to use it? What kind of range do you get with a mobile unit? A base unit? I know these are a lot of questions; however, I would appreciate your views and information. Always, Karl |

The laws may be different in Australia. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

I know these are a lot of questions; however, I would appreciate your views and information. Always, Karl SSB is a type of modulation, like AM and FM. Most CB radios use AM only. SSB uses half the bandwidth, so you can cram two SSB 'channels' into the space of one AM channel. Those SSB channels actually use the same channel frequency as the AM channels but are divided between the upper and lower half of the channel, or USB and LSB (Upper Sideband and Lower SideBand). One advantage of SSB is that it receives half as much noise as AM because it uses only half the bandwidth. Another advantage is that you have more effective power with SSB. Watt for watt, SSB has about 9 times the power of AM. SSB radios are more expensive, but you don't have to change the antenna or anything else. You -do- have to use one more knob, the 'clarifier', which makes voices sound normal instead of like ducks. Range for any mode depends mostly on your antenna and your terrain, but with any given antenna the range using SSB will usually be several times greater than using AM. Legal power for CB radio is limited to 4 watts AM or 12 watts SSB. You don't need a license for CB regardless of whether you use AM or SSB. Hope that helps. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- hey frank, the above poster asks about single side band. have you ever come across double side band? |

Nope, not unless they were accompanied by a carrier. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

DSB does exist.
"Got RF?" |

Hello Ozark 333:
Yes it does. My ol friend "Ray" Buckshot use to raise havic with the local SSB guys with a old Imperal Rang Gain, that had DSB, it transmitted on both uper and lower Side Bands at the same time. Ray would record the SSB stations while in the AM Mode so the stations where not tuned in and of course sounded like Donld Duck. Then replaying the recorded SSB stations back out on DSB. No matter what you did you could not tune in the stations that ray was playing back. It throw me for a while, until I called Ray up and asked what the heck he was doing. We had a good laugh! Other radios had a DSB output also. I believe the Trams did until the Tram 201 and 201A came out. One of the first radios to have true single sideband was the Johnson 350 a two channel SSB only radio, and the Mark Sidewinder 27, a 6 channel radio, with no S-Meter, made by Dyascan I believe. General Radiotelephone came out with the SB-72 that offered true Single Side Band, and had a Collins Mechnical Filter in the radio. Jay in the Mojave OZARK333 wrote: DSB does exist. "Got RF?" |

Put a switch in the AM Carrier adjustment circuit to turn off the carrier on AM, and you've got DSB... Easy as pie. |
