jstack is right, if that was your question. I thought you were asking how wide.

does anyone one here know much about Single Side band? is it worth having in a wide band receiver or not?
the only modes it has a AM, FM and WFM |

Voice on the ham bands below 29MHz (10 meters) is sideband, so you will have issues listening to that. It can be done with an AM receiver, but it will be very hard to understand. Commercial SW stations, however, are standard double-sideband AM, so you will have no problems with them. You also will have problems with CW (morse code) and some of the digital modes hams use, since there are no filters for them.
What radio are you looking at?

I'd like to see more than 500 channels on a radio with that wide of a receiver, but it'll do. |

SSB is used for Amateur Radio, "Utility" stations, and military HF traffic. If those things interest you, you'll need a radio that can receive SSB. Keep in mind that you won't get much reception with the whip antenna. Some of the AOR models had a ferrite-bar antenna ("loopstick") for broadcast-band reception, but what I can find on that one indicates it doesn't. Even a 10' piece of wire stuck into the center of the BNC will make a noticeable difference for AM and shortwave reception.
Manuals can be freely downloaded from the AOR website.

| All the utility stuff I've listened to has been sideband. There might be some still using AM or DSB, but all the "shore stations" I'm aware of went to SSB quite a while ago.
But then again, I don't go looking for AM/DSB in those frequency ranges.

Most if not all transmissions on the ham bands below
30 mhz are on sideband, anything below 14 mhz (20 meters)
is lower sideband (LSB) and anything on 14 mhz and above are
on upper sideband (USB).
The ham bands are further broken down by mode.
The following URL should explain the band plans which are
universally agreed upon by gentlemans agreement.

one of the more interesting things i listen to on my kenwood ts440s and yeasu 757gxII is the aeronautical frequencies on USB.
heres a link to them.
»wiki.radioreference.com/index.ph···Stations
this is where you will hear first hand any distress or problem with an aircraft carrier traveling overseas.
these frequencies are used when the normal VHF frequencies are out of range.
its interesting to note the size of the horizontal polarized antenna used at some major airports for these frequencies.
imagine, being a ham operator, having one of these in your backyard.

i forgot to mention, if you want the best reception, you can make a dipole antenna at a specific length relative to the frequency.
here is an online calculator you can use to cut various lengths of copper wire for use at certain frequencies.

The use of LSB below 14.0MHz and USB above is "by gentlemen's agreement" (albeit based on technical considerations), but the band plans, in general, are not. Sub-bands are determined by the licensing authority (FCC in the U.S.), and certain modes are restricted. Typically, the lower portion of a ham band is CW/RTTY/Data only, with voice modes at the higher end.
