CB question

I know a lot of people here are using the Cobra CB but has anyone had any experience or knowledge with this Midland 75-820 Midland CB

Also any good ideas on attennas and how long should I get.

Thanks

If you're really worried about communication then get your amateur radio license and a good 10 Meter radio. But if you're simply looking for a piece of equipment you can chat to truckers with while traveling along the interstate then just about any CB radio will suffice.

Regarding CB antennas- the most important thing to remember is to ensure a good ground and properly calibrate the SWR's (Signal to Wave Ratio). You'll check the SWR's on channels 1, 20 and 40 and are looking for 1.1:1 and no worse then 1.5:1.

You want the antenna to be as tall as practically possible. The antenna should be taller than any other part of the vehicle and if the antenna has a load then make sure it's above the top of the vehicle.

I've never used that model CB but some of them with all the functions on the mic are easy to accidentally change channels and other settings.

I thought the same thing Randy. I have a buddy selling a brand new one for 75 dollars and thought it would be a good deal.

Thanks again

I have a question also, when I key up my cobra with my stereo on, it squeals like a pig. Is that a ground problem or something?

Yep. RS has a cheap "all weather" one that's good for soft tops; I use it in my wagon as well.

While other radio technologies may be alot better, around here CB is the "standard" that everyone on the trail uses, and is what the log truck drivers use in the back country. A radio does you know good if you can't talk to anybody with it.

I mounted my antenna in one of the lamp mounting holes on the ARB bumper.

Evidently some may need some clarification.

A 10 Meter radio, and any other ham radio for that matter, is going to have the ability to tune and transmit on citizen band (CB) frequencies. (Channel 1 = 26.965MHz to Channel 40 - 27.405MHz) Your friendly truckers are going to be on 27.185 These are the most available and open freqs out there, hence "Citizen Band".

Misconceptions galore.


I actually used that midland while spotting over the weekend (out of the truck and too far from my base unit). Seemed to do the job although as a handheld, range was limited by the rubber duck antenna. It was great on batteries though.

The antenna is the most important part. Cheap CB's work just fine. My Cobra has the weather band and I appreciate that. Tune your antenna! Either borrow, buy and use a CB shop with a meter and tune that antenna. My KB antenna has a little shaft that extends to tune it. Others you may have to remove the tip and cut. Cheap ones don't require tuning because THEY SUCK. Firestik makes a nice tunable antenna, too.

Personally, I find CB's suck in general. FRS/GMRS radios are better, but I can't fine a permanently installed "CB style" FRS/GMRS radio--one that preferably can do both CB and FRS--do they exist?

Really? I did not know that. The 10 meter band runs from 28-29.7 MHz, above the CB band. A brief Google search did not reveal any 10m mobile transceivers that were also set up to operate in the CB band; can you point me to a particular model?

BTW, it's called "citizen's band" because that's what it is labelled in Part 95, Subpart D of the FCC rules; i.e., "Citizens Band Radio Service": a 2-way service indended for use by the general public. In the dom drak past you actually needed a license (no test, just fill out the form), but I think that was done away with during the Carter Administration.

Edit: that should be: "dim dark" past.

OK, now I owe an explanation.

10 Meter Radios are NOT CB radios. That means that they will NOT get any of the 40 CB Channels out of the box. Don't expect to buy a new 10 meter Radio, take it out of the box, plug it in and talk on channel 19. The 10 Meter radio is an amateur radio and NOT a CB Radio. Well, at least that is the claim of the manufacturers of these radios. The FCC on the other hand claims they are really CD radios in disguise and therefore need to be on the FCC's approved list.

Anyway, very simple Frequency modification can be legally done by you or any CB shop. You can legally listen in on the 40 CB Channels, but it is technically illegal to transmit on those channels do to the power which easily exceeds the max 4 watts of the legal CB radio. You should also have a License to operate a 10 meter radio.

The antenna is the crucial element of range but at some point you cannot mount a bigger antenna on your truck so you have to go back to increasing the power of the radio.

I have a cobra all in hand with a tunable firestick antenna. Been real happy with both. The cobra has a "lock" botton that prevents you from changing settings on accident. As others have said, put your money in the antenna, that will make a bigger difference.

so Matt, exactly what do I want to buy, a 10 Meter radio and decent antenna, then take it to my local shop and ask them to tune it to the CB channels as well? So can I buy a cheap as dirt 10 meter radio and good antenna (is K40 good, Firestick, which one, you tell me and I'll be on it) and get pretty good performance?

I've got 3 cb's sitting around, and was never really happy with any of them, and want to just get it right this time.

Thanks

K40's are no longer in business. You can find them, but the companies direction is different so their lifetime warranty is good only if you find someone with them still in stock. Although I have one, I would get a Firestick nowadays.

Hmm, well I own several radios but one particular radio i like is my Galaxy 99. You can order these pre-tuned on the web that are ready to go and include all of the upgrades. Like Chris said, the FireStiks are tough to beat for vehicular purposes. I also like Wilson or Monkey Made.

If you are lucky enough to have a CB shop nearby (they're a dying breed) that's going to be your best bet. They'll be able to assist you on everything from selection to installation and service.

A lot of the larger truck stops have a CB shop. I bought my CB online and installed it, then I took it to the CB shop at the truck stop a few miles up the interstate from my house and bought the the antenna. The guy sold me the antenna, bracket, cable and installed and tuned it for about $35. Interestingly, he said a few weeks before I showed up the Dallas Jeep club brought in about 15 trucks for him to install radios into. I'm no expert on CB, but I asked him about buying the longest antenna. He suggested a 3' length whip type antenna and said there would not be much to gain by going longer and it would be more likely to be damaged. It's mounted to the top bracket of the spare tire carrier and extends about 12" - 18" above the vehicle. I've never tested the range, but it works great for convoys and trails.
