Ok, got a ssb question

[Phaze91460]

back in the day this was a moot point. We only had 11 meter band and 40 channels.

I know that SSB is only half of the AM band, carrier and modulation on either the upper or lower half of the am band.

So, with export radios ( 10 meter converted ) the AM mode has quite a few Bands with 40 channels in each.

The question is.......... ( Drum roll ).....Is there a upper and lower side band mode to each AM mode bands ?

Did I confuse everyone ? Example: USB mode, Band A - B - C - D - E - F - G - H and then the same on LSB ?

Or is SSB only available on 11 meter 40 chans on the CB bands ?

Phaze, look very closely at what you just wrote.... you just answered your own question.

DEFINITELY any channel you select will have upper and lower sidebands. The channel is simply a frequency. The AM, USB, and LSB are transmitting modes on that frequency. Just as you can transmit in AM on any of those frequencies, you can transmit in USB, LSB, and even FM if your radio is capable of those modes too.

Yep...whatever channel you are on you can use SSB. And SSB transmits strickly modulation...no carrier per say. Unlike the AM which the modulation travels on the carrier. Part of the reason I like SSB is that if your radio is capable you can slide 5 Kc's down/up and have a whole other channel for further DXing. I've talked to many other countries over the years like that. Especially Australia and New Zealand.

I have been doing searches on 10 meter/sideband and this thread came up. This is what I have wanted to find out, but I am thick headed and don't understand the answers given.

Let's say you have a 10 meter radio (modified for regular CB channels) and you have the Band selector set to "D", which I understand would be your regular 40 CB stations. If you turn the Band selector to "C", would that be LSB? If you turn the selector to "E", would that be USB?

Thanks in advance. Please make the answers simple for your village idiot.

If your on Am on band D and switch to band C or E it will still be on AM
unless you switch it to LSB or USB.

Well, as stated, for any given frequency, there is am, USB, LSB, FM, CW, and whatever mode your radio has. Example: For any "channel" you are on whether its on band a,b,c,d,etc. you are on a frequency. For example, channel 40 is 27.405. Beyond that, for every frequency are several modes you can use to communicate. That mode may be USB,LSB,AM,FM, etc. and not all radios have all modes, such as fm and ssb.

Channels are generally only used in cb, FRS, and marine radio terms and on 10 meter and every other ham band and freeband, frequency is used, such as 28.400 mhz. No matter what rig you are on and how it shows it, 28.400 is just a frequency, and on that frequency you can operate various modes. On cb, we have fallen into a rut and everyone mentions channels. A channel is just a designated number for a given frequency. Channel 19 is 27.185, channel 40 is 27.405. You can be on channel 40 on any "band" on your radio and they translate to different frequencies, depending on which 10 meter or export rig you're on, and they vary. Band "b" channel 10 on one may be a totally different frequency than band "b" on another radio. This is just how the radio is designed and has nothing to do with the mode or any other official designation. A mode is a form of operation for a given frequency and has nothing to do with the channel.

Sideband is simply a by product of producing an AM signal. When you talk on AM, your audio is what creates the upper and lower sidebands. One day, a rather smart individual figured out how to eliminate the carrier and the opposing sideband with using either a low pass filter or high pass filter (depending on which sideband you wanted to transmit on). See the following link, it might explain it a lot better.
