Because your Cobra CB radio is legally limited to 4 watts AM and 12 watts SSB.
That 10 meter ham radio puts out 25 watts IIRC. 25 watts takes a bit more to cool off than 4 watts. It also makes it illegal to transmit on the 11 meter CB band.

sparky Very good, it's a lot of fun. For local communication 2M & 440 is what is mostly used. HF mobile on 10M can be interesting especially when propagation is good.

Any questions on the test or how to proceed, PM me.

It's a SSB, too. But it has the cooling fins.
Putting it up above the rear view mirror, I'm kinda worried about the heat dissipation coming off the back of the radio, constantly pushing towards the windshield.

As far as heat, it might warm up in FM, but for AM and SSB it should stay cool.

Jerry Bransford Those cooling fins don't put out enough heat to worry about, a CB radio doesn't put out enough power to get the cooling fins hot. Not to mention it only happens when transmitting.

My bet is once you actually start using the radio, you'll soon see that SSB isn't used on CB enough any more to warrant the extra cost. I use SSB on my HF ham radio all the time but I can't remember the last time I heard SSB used on the CB band.

The radio should come out of the box, tuned & ready to go.
It's the antenna that should need tuning.

the Kolector Just an update, i went ahead and got the SSB, installed on my Rugged Ridge dash tray, used the Cool Tech Ultramount kit. I even bought the Firestik splitter so my CB antenna is pulling double duty catching my AM/FM radio signal as well.

Tfrench40 Go for the SSB rig, Its far better to have that capability and NOT need it than the other way around. Look at it like this, stock CB output is 4 watts, SSB peaks out around 10-12 watts and if your in a jam that little bit of extra just might be what you need. Otherwise you will need an illegal amp to make sure you get out.
The little bit extra you get from the shop "Peaking & Tuning" your rig is only $$$ in their pocket, from the factory it is set around 70-80% modulation and they simply crank up the output to 100%, anything past that and you are flattopping your signal and its crappy audio plus over driving the transmitter circuit which will fry your finals faster. just my 2 cents worth. 73, Frenchie N3UFJ

First, VERY few CBs have SSB ability. And unless you know where to look, it's hard to even find a CB with a SSB mode. SSB is rarely used any more on the CB band and its use is pretty well limited to CB enthusiasts/hobbiests. And if the CB at the other end doesn't also have a SSB, they wouldn't be able to understand your SSB signal anyway. A SSB CB radio cannot communicate in SSB with a standard CB radio like is used for offroading... they wouldn't be able to understand each other.

For offroad use, SSB is not needed or commonly used. In 15 years of offroading with a CB, I have never, not even once, heard anyone using SSB.
Jerry is VERY correct! (hey... I rimed! LOL) BUT... I plan on being with friends who also have SB radios. I didn't drop $55k on my jeep to save $50 on a stupid radio. (AM vs SSB) I bought what people said was a decent radio, then I wired it correctly, I bought good coax, I doubled my high quality RF ground cables I worked on my SWRs & RF output, and "F" the clubs! I got a big whip! By the way, I'm very happy about mounting it in the overhead above the mirror. I bought the G.E.A.R. overhead console, which I love, and hard mounted it there.

Do it or don't do it but why be half-assed about anything!

Yes! However, some can really benefit so you increase your output slightly and you increase the modulation BUT not to the point of not being able to understand your spoken words. In fact I don't like it even near that point. You might be illegal but linears can increase the output. Just remember what the other wise members hav said. You can out transmit your reception capabilities. I like to have someone really professional inspect my complete instalation and then make suggestions on RF ground, SWRs, tweaking the radio.

Good luck and I'll leave the light(SSB) on for ya!

You know, I was just thinking about this until I read this post. I went and bought top quality parts so that when my install is completed I'll know that it will work right and the stuff will last longer. Buy the best that you can afford or wait a little longer and save for the better radio/antenna/coax. In the long run you'll save yourself a lot of aggravation. And dont take shortcuts do it the right way. Take time to make it look like it was meant to be there.

lensam The cool thing about SSB is if you spend a little more time in your Jeep like... being in traffic, it might be interesting to listen in on conversations people are having on sideband. Maybe you could break into the conversation and find out where they are. You'd be suprised as to where they might be. For example, years ago I had an old Radio Shack SSB radio and a trunk lip mount antenna and on my way to work I talked to someone from Hollywood FL and I'm in CT. HAH! And I think I got the setup out of a junk car at the time.

genesbro For trail use am radios are the norm. I have always used a Cobra 148GTL ssb rig in my offroad adventures. One reason is it has a far better receiver than most am only rigs. I have been in areas where there is a s9 noise level and turning on the NB knocks it down to s2. Most am only rigs are lucky if they can get it down to s8 or at best s7 in the same situation. Of course I am old school and I run a Cobra 2000 as a base station and using a homemade set of stacked 3 element beams have talked with another base station over 80 miles away. For that range we were using SSB of course and it was at night so the skip wasn't causing interference or that would have been impossible.

Anyway am is all that is required for trail use. But you also don't need lockers to run trails either. SSB is like lots of other things, don't have to have it but is does also get you a rig with a better receiver and even when the skip is in can help you reach other members of your group if they also have it.

Was on a run with a group once at high dessert roundup and reception was terrible from all the skip and another guy in the group has SSB and when it got to hear each other we switched over to that mode and it was almost like we had the whole channel to ourselves, it made that much difference. That was about 20 years ago now and there are a lot less people that use SSB radios these days. To me having SSB is like having 4x4. You don't always need it but is nice to have it handy just in case.

the Kolector I went ahead and got the Uniden Bearcar 980 ssb, I had an Amazon giftcard that pretty much covered the difference, got it delivered from FedEx yesterday and installed lastnight. Now I have to tune it.
01-20-2013 08:56 PM
lolpetewtf No extra tuning required. Just throw it in USB/LSB on 16, 36, 37, 38, 39 or 40 and talk away.
01-19-2013 10:15 PM
Jeepnolan I would definitely go with a SSB radio. I used a Uniden Grant SSB radio in my 95 YJ and just recently installed a Cobra 148 in my TJ. Both are SSB radios. With the right conditions, you can talk clear across the US with a decent 4' antenna and stock SSB radio. Just my two cents but once you get into it, it's pretty cool.

Well, MSRP difference is actually $30, but hey, whos worried about a measly 30 bucks, right? The reason for the discussion is because I was interested in the difference and if it is something worth wasting the extra money on. I don't know much about cb's and found one I liked that came in two different variants, don't know if its harder to tune or required anything special, hence this discussion. No better way to learn than to ask questions, right?

Thanks, thats kinda what I was thinking, that it wasn't really common enough to justify the additional cost.

BlueRidgeYJ For sure, but remember that sage advice: Buy once, cry once.

One thing to add about ssb - because all the modulation is contained in a smaller spectrum of band space, more crisp reception is heard on the other end. Less "static-y".
12-10-2012 08:44 PM
the Kolector Awesome, thanks. Yea, it will just be trail riding and, unfortunately, won't be too often, so with as little as it will actually be used, I think the 880 will be my best bet, I can always upgrade later, right?

Well to answer your original question, what is the difference:

Single Side Band (SSB) transmission is a mode of operation, not a band of frequencies. All cb radio waves are comprised of 3 parts: a carrier wave that uses ~50% power and 2 equal side bands that use the rest (upper & lower). The carrier wave rides the freq setting on the radio and the sides deviate equally beside it. SSB operation takes the carrier wave and 1 of the side bands and throws them out the window, so to speak. The only wave actually transmitted of the 3 is the side band you are using, which is sent with more relative wattage than a typical "3 part" wave, because all power can be focused on it. It also uses less bandwidth by more than 50%, perceivably "adding" twice as much space on the band, but only if everyone does it.

This is all in addition to being able to operate in normal mode.

If others are talking with normal mode, and you are talking on the same freq on ssb, you will be trying to occupy the same side band/frequency.

You don't need it, but it is a neat feature. If you expect to advance in RF comms, go for it. If it is a trail only kind of deal, hold off.
