I don't think I'm getting out there as far as i can. Most likely this Friday I will be purchasing a Wilson 1000 Magnet Mount to replace the antenna I have now. Is that going to get me out there a little more (the wilson 1000) No modifications have been made to this radio and have not been able to find any either. I purchased it brand new at a Pilot Truckstop, and am sure it is only putting out 4 watts (fcc required). Will the Wilson make me receive further or transmit further or both, or neither? I'm new and feel it all has to do with how much your getting out ( 4 watts doesn't seem to good ) All domestic CB radios are rated at 4 watts. Unless you are running an amplifier, no one radio will significantly "put out" any better than another. What you use for an antenna, though, is a different story. The antenna will make a much bigger difference in signal than the radio. Generally speaking, the longer the antenna, the better it performs. The largest CB mobile antenna, is a 9' whip. If mounted in the center of a the vehicle, there isn't much that can touch it. Maybe I don't need a new radio, maybe the wilson 1000 will do what I want it to do. I get so sick of losing communication once I'm not close to truckers anymore. What do I need to do? I want to make sure i am getting out as far as possible. My other dilemma: I've been looking here http://www.wilsonantennas.com/cobracb.shtml at some of the radios and the three that have caught my eye a Cobra 29 LTD Night Watch Classic Cobra 25 LTD Classic Cobra 148 GTL Classic These are fairly nice radios, although there are continual rumors of diminished quality due to their place of manufacture. A better alternative would be the Uniden line of radios. My favorite is the Grant. The site also offers two tuning options before shipping. Which one should I go for? Seems like the Mega Tune. One more question below as well. The tuning options a The Mega Tune 29.99 Our Mega Tune is designed to provide you with loud booming audio while still maintaining a clean and clear signal. If you looking to sound raspy or bleed over many channels this defiantly isn't the modification for you. Our techs have worked very hard to perfect this modification. The mega tune will not void any factory warranties, it will not damage your radio and it will not make your radio run warmer than normal. We also do not remove or disable any part of the AMC or ALC circuit. We do upgrade various parts of the audio circuit with higher wattage or better quality parts. We also do a few other modifications that make the radios wave form, when viewed on an oscilloscope more linear. This means of course you will sound as loud as possible while still maintaining maximum clarity. If you are looking for maximum performance from your radio we recommend you have us perform this modification. We also completely warranty all work performed by our service department. The mega tune will also increase your peak power. Dual final radios after being mega tuned typically put out over 40 watts and single final radios typically put out over 30 watts. The True Tune 10.00 Our True Tune is like a basic peak and tune. When you receive your radio that have been True Tuned by Premiere Electronics you can rest assured that your radio is operating at it's maximum efficiency. We go through your radio and re-align the transmitter section. The reason this is necessary is because from the factory most radios just aren't working at their best. The factories don't have the time to sit down with every radio and precisely tune it. They generally get it in the ball park, but if you are interested in performance, you need the true tune. Every modification we perform is backed up with our unbeatable warranty! Like always, none of our work will void any factory warranties. Run, don't walk away from peak jobs. They do nothing more than remove your hard earned money and put it into someone else's hands. All that is usually involved is peaking the power output for maximum, and removing or reducing the affects of the modulation limiter. I won't go into the math here but in order to see even 1 "S" (signal) unit increase on another guy's meter, your radio would have to put out 4 times as much power as it did stock. It is VERY difficult to get 16 watts of dead key power from a 4 watt CB. It cannot be done by alignment alone. By the time someone "redesigns" the transmitter and replaces the parts necessary to get up to 16 watts, you are left with a radio that may very well be less reliable, or may have a dirty or unstable transmitter. If you truly want to get a boost in output power, you are better off with an amplifier. Yes, an amplifier is illegal as heck, but so is a peak job. Last question: The one that bugs me. I purchased a SWR Meter from Radio shack. It was the cheapest one they had and I am on a budget here, because some they had were way to expensive. The one I got was http://www.radioshack.com/product.as...ct%5Fid=21-534 I took it back because nothing seemed to make much difference, or I wasn't operating it right, seemed to always fall in the red. The antenna I have the only way to adjust is to move antenna up and down. Maybe I wasn't in a good location. I finally got it to 2.3, and just left it. My question is was I operating it right to finally get a 2.3 or is that just a cheap ass SWR Meter? That meter should do the job. How were you using it? To check SWR, you need to set it to the "CAL" position. Key the mike on your radio and adjust the calibrate knob on the meter to the red cal line at the right of the scale. Then switch to SWR and read the reflected power on the SWR scale. A good performing antenna will have an SWR less than 2:1 (1.5:1 preferable) Hope that helps... Dave "Sandbagger" http://home.ptd.net/~n3cvj I just don't know how to thank you. You answered my questions perfectly. Maybe for now I'll just keep the Cobra and get that antenna Friday and see the differences. I'll go back and purchase a SWR meter as well. My uncle that i rarely talk to is really big into ham radios and cb's. I bet he has a SWR meter, and I'm just gonna call him and see if I can borrow it. |

Twist: Actually, there is a correlation. If two radios are set up in a "fixed" location, each, and one transmits a carrier, there will be a reading on the "s" meter of the receiving radio. Assuming the two radios are far enough apart so that the transmitted signal does not register above, say, s5 on the receiver, it is possible to get a relative power reading from the transmitting radio. Now if the transmitting radio increases power fourfold, say from 4 watts to 16 watts, the receiving radio should now show s6 on its meter. This of course assumes that the receiving radio's ALC is tuned properly and that the s-meter is calibrated properly. In a properly calibrated receiver, a 3db increase in received signal strength should show about 1/2 of an S unit. Doubling the power output is the equivalent a 3db increase. It's a moot point, but output power does indeed have something to do with "s" units, to the receiving radio. There isn't a direct correlation, and most CB receivers probably aren't calibrated properly, but there is a correlation, nonetheless. To the original poster: as for the antenna advice, a Wilson 1000 is a decent antenna, and will do fine. You will notice increased receive and transmit range while still remaining legal. Hope this helps. -SSB Thanks so much. With all the trolls in here I wasn't sure I would get a decent reply. thanks again. |

I don't think I'm getting out there as far as i can. How far are you transmitting? On a clear channel, or busy one? If I am not mistaken I am getting maybe 3- 4 miles at times on busy and clear channels, but again i could be mistaken Most likely this Friday I will be purchasing a Wilson 1000 Magnet Mount to replace the antenna I have now. Is that going to get me out there a little more (the wilson 1000) No modifications have been made to this radio and have not been able to find any either.

I'm new and feel it all has to do with how much your getting out ( 4 watts doesn't seem to good ) 4 watts is actually a great deal of power. The first mistake a newcomer makes is believing power determines range. Yes, I did think that. I thought damn to actually get a good radio I'm gonna have to be illegal. Now I think otherwise. The Wilson antenna will increase both your transmit and receive range. Thats what i was hoping for. Maybe I don't need a new radio, maybe the wilson 1000 will do what I want it to do. I get so sick of losing communication once I'm not close to truckers anymore. What do I need to do? I want to make sure i am getting out as far as possible. Is your radio tuned to your antenna? Again a newcomer mistake... not adjusting the SWR of your system. Just dropping a radio and antenna into a vehicle and operating is not all that is required. You must make sure the antenna/radio/vehicle combination are matched up with one another. You can search on the web for how to adjust SWR. The best i could get it. I finally got it to 2.3, but gonna recheck it when I get my Wilson 1000 Also, antenna location is important. Placing the antenna right in the middle of the roof of your vehicle is the optimum place to mount an antenna. Especially if it is a car. To make it simple.... the metal in your vehicle will act as a "guide" for radio waves. Wherever the most metal is is the direction the radio waves will be directed. The center of the vehivle will direct your signal equlally in all directions. Placing an antenna, say on the roof of a pickup truck will actully direct the signal BEHIND the vehicle, since you have the whole bed of the vehicle to guide the signal. Mounting your antenna, say on the driver's side mirror of a car will actually direct the signal to the left, side and rear of the vehicle, while sending a diminished signal to the front and left. Hope that makes sense. My other dilemma: I've been looking here http://www.wilsonantennas.com/cobracb.shtml at some of the radios and the three that have caught my eye a Cobra 29 LTD Night Watch Classic Cobra 25 LTD Classic Cobra 148 GTL Classic To be honest.... any and all radios will perform for the most party, the same. They differ in "bells and whistles" only. I had one of the first generation Cobry 19 Plus radios.... best sounding radio I ever had... perhaps the newer generations are similar. The site also offers two tuning options before shipping. Which one should I go for? Seems like the Mega Tune. One more question below as well. The tuning options a The Mega Tune 29.99 .... The True Tune 10.00 .... If you want to stay legal, stay away from this stuff. The only legal way to operate a radio is out of the box. I have yet to see a peak and tune that doesn't sound awful, or bleed over. To be honest, most radios ARE undertuned. You CAN get set up to run at the full legal 4 watts, and not exceed modulation limits. Just go to a trustworthy shop. Last question: The one that bugs me. I purchased a SWR Meter from Radio shack. It was the cheapest one they had and I am on a budget here, because some they had were way to expensive. The one I got was http://www.radioshack.com/product.as...&product%5Fid= 21-534 I took it back because nothing seemed to make much difference, or I wasn't operating it right, seemed to always fall in the red.

My question is was I operating it right to finally get a 2.3 or is that just a cheap ass SWR Meter? In the red is VERY BAD.... A factor in your range for sure. 2.3 is not too bad... you want an SWR under 3. See my above on antenna location. I figure you have your antanna tuned as good as it can be. Your SWR meter was working properly. All it does is tells you the truth. Some vehicle/antanna combinations don't agree with one another. I really hope someone has the time to answer and help out a newbie as I am very interested in Cb's since i finally broke down and got me one. I just want to be able to transmit and receive as far as possible without breaking the law to bad. Not ready for a amplifier or anything like that. Good deal.... best way to be. Hope I helped. |

I get so sick of losing communication once I'm not close to truckers anymore. What do I need to do? I want to make sure i am getting out as far as possible. The most important part of any radio system is NOT the radio -- it's the antenna. It's the antenna that converts signals to and from the ether. If your antenna sucks, so will your communication REGARDLESS of what kind of radio you have. That being said..... The best mobile CB antenna you can buy is the 102" whip (it's also one of the cheapest antennas). Shorter antennas are a compromise between length vs. performance. The longer the better. And if you want your antenna to do the job it's capable of doing you have to mount it properly. Generally, the higher you mount it on your vehicle the better, but it's much more important that your mount is well grounded. Mag-mounts are mediocre at best. No-Ground-Plane (NGP) antennas are worse, and thru-glass antennas are junk. My other dilemma: I've been looking here http://www.wilsonantennas.com/cobracb.shtml at some of the radios and the three that have caught my eye a Cobra 29 LTD Night Watch Classic Cobra 25 LTD Classic Cobra 148 GTL Classic There are two things you can do to make even a cheap radio talk much better: Get an external speaker and a better microphone. The site also offers two tuning options before shipping. Which one should I go for? Seems like the Mega Tune. One more question below as well. The tuning options a snip Like Dave said, avoid the peak jobs. Especially one's where they claim to get 30 watts out of your radio and not void the warranty -- any warranty is voided when your radio is modified to exceed the legal limit of 4 watts (which translates to 16 watts peak/PEP). Most of the shops that offer peak-&-tune jobs are chop-shops that will tell you anything you want to hear just to get your money. And yes, some of their claims are flat-out lies, including the text you quoted in your post. (The work is illegal, so it shouldn't come as a shock to find out that their advertising is also illegal.) The best thing you can do to improve your talk-power is to use a quality mic. You can improve it even more with an audio compressor, and don't exceed about 30% compression. Last question: The one that bugs me. I purchased a SWR Meter from Radio shack. It was the cheapest one they had and I am on a budget here, because some they had were way to expensive. The one I got was http://www.radioshack.com/product.as...ct%5Fid=21-534 I took it back because nothing seemed to make much difference, or I wasn't operating it right, seemed to always fall in the red.

My question is was I operating it right to finally get a 2.3 or is that just a cheap ass SWR Meter? The meter probably works ok, and your location shouldn't make much difference (unless you are parked inside a steel shed). It's more likely that you have something wrong with your antenna and/or coax. The antenna could be poorly mounted, the coax could be old (don't use foam coax!), the connectors could be bad, etc, etc. My first guess is that mag-mount antenna you are using is junk. I really hope someone has the time to answer and help out a newbie as I am very interested in Cb's since i finally broke down and got me one. I just want to be able to transmit and receive as far as possible without breaking the law to bad. Not ready for a amplifier or anything like that. Amps are not only illegal, they are expensive. The laws of physics dictates that you need 4 times the power to double your range. That means you need an amp capable of 16 watts AM. The problem here is that most amps are rated for peak watts (PEP), which means you need 4 times -again- as much power; i.e, a 64 watt amp. THAT's how much it takes to double your range, but -only- during transmit, NOT receive (and that's assuming you have an IDEAL antenna operating under IDEAL conditions). Ok, so you get a 64 watt amp, and after a while you want even -more- range. To double your range again you would need an amp capable of 256 watts. Double it again and you need over 1 Kilowatt! By the time you reach that point you are in it for the big bucks -- to run that kind of power you need two or three heavy-duty alternators (with all the pulleys and other hardware), battery cables thicker than your thumb, high-quality coax, an antenna capable of that much power, ....$$$$$ And here's the ass-kicker: if your range was 1 mile without the amp, you have only increased your range to 8 miles! On the other hand, a better antenna can do the same job or better for -both- transmit and receive. It's also much cheaper. And it's legal. I seem to like the site I am planning on purchasing from unless someone out here tells me there is no need for another radio because the Wilson 1000 will do what i want. I guess the reason i also like them is that they will tune and get everything running just right before they ship it. I know that wasn't done to the one I have now. To get everything running right you need to install everything properly. They can't do that through the mail. Go to the library, find a book on CB or ham radio and read it. That's the best way to learn how to do things right the first time, and not pad the pockets of sham artists with your hard-earned money. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I receive all kinds of stuff, but not always able to talk back to the people I hear. Its the transmitting, maybe I am just want more than any cb antenna can offer. How far ( guesstimate ) if everything was just right would this 102" be able to transmit. Please don't tell me the Wilson 1000 isn't good. I've heard to many good things about it from about 30 different people, owners of the antenna. |

I have both the Wilson 1000 and the 102" and the problem I have with the whip is the clearance under trees and such. It has the nickname "tree pruner", but it really can't be beat for performance. They're both good antenna's. |

You didn't say the brand of the antenna or where it is mounted. The antenna
is the most important part of the whole system. You want an SWR of 1.5:1 or lower. One common mistake is to put something under a mag mount antenna to protect the paint. Don't do it. You'll never get a good SWR reading. Also, unless it is a shunt loaded antenna like the Wilsons, you want the loading coil above the roof. You'll be happy with the Wilson and if you can mount it, get the trunk mount. They are harder to steal and give a better ground. The radio you have should do just fine, once you get your antena problems worked out. As for the peak and tune deal, there are many opinions and preferences. Firstly, the radio is designed around a 4 watt output. It is adjusted not only to meet the 4 watt legal limit but also to minimize harmonics. Just leave it alone and definitely don't have parts changed. The Mega-tune didn't sound too bad til I got to the parts changing part. I usually tweak the modulation up just a hair but never disable the limiter. Invest in a good power mic like an Astatic, Turner, or even a Cobra CA-75. This will improve your audio tremendously. If you want to talk farther, look for a radio with upper and lower sideband. I won't go into a big explanation but if you want to know about AM and SSB, do some internet searching. There's alot more to it than can be explained here. Also check out http://www.1stopelectronics.com . There is a forum there that you can read through and ask questions. There are some people who do some crazy things with radios but also alot of people with some good advice on good basic radios.

Nothing was insultive was said to you in the above post. Really? It's funny, when someone even remotely suggests that you're opinions are off the mark, you accuse them of "getting personal", yet you don't seem to apply the same consideration when you refer to advice as "voodoo bull****". But he's way out of his element and way too far into mine if he wants to talk about radio theory. Hehe,,,,that's the davie we're all used to, the one that needs to blow his own horn. If the shoe fits. In all likelihood, I've probably forgotten more about the technical aspects of radio than you know now. It ilustrates your blown self-esteem. I guess if I was as ignorant as your remarks about FCC law that hold roger beeps illegal and dxing as a felony, Deny all you want. DXing IS illegal, and roger beeps were at one time considered in the same vein as other noisemakers as devices to amuse or entertain. I would hurry up and start tooting my own horn about another area of which I have slightly more knowledge than that of the law which governs "your" element. I understand the law well enough. At least I'm not blatantly disregarding it. Nevertheless, tuning a 4 watt radio will not affect any "S" unit on the receiving end. You go on and believe it will and continue to sling your voodoo bull**** that is found in your posts from your claim of making a Davemade "spectrally pure" (something which you are unable to define, but claim you did) to your bull**** about increased S units from a 4 watt radio. Are you THAT literal? Are you disputing my claim because you're hung up on the absolute definition of a "4 watt radio"? The term "4 watt radio" in this context, refers to a stock (legal) CB. If you peak the radio, of course it will no longer put out 4 watts, otherwise why do it? The truth is (a truth that you're either too anally specific about or unable to comprehend) that if you double your transmit power, you increase your signal by 3db. A typical "S" meter is "calibrated" in 6db increments. Therefore, assuming a linear (no not the amplifier) scale, an increase of 6 db (1 "S" unit) is the equivalent of taking a 4 watt carrier, and increasing it to 16 watts. Something that is not possible from a simple "peak job". There's nothing "voodoo" about it. But don't take my word for it. Check out some books on radio propagation, and read it for yourself.

Absolutely in agreement...
Professor www.telstar-electronics.com All domestic CB radios are rated at 4 watts. Unless you are running an amplifier, no one radio will significantly "put out" any better than another. What you use for an antenna, though, is a different story. The antenna will make a much bigger difference in signal than the radio. Generally speaking, the longer the antenna, the better it performs. The largest CB mobile antenna, is a 9' whip. If mounted in the center of a the vehicle, there isn't much that can touch it. |
