you could, but thats a little more work than im willing to do.  i usually only have my cb on when im trail riding anyways.

as far as fcc regulations go i believe you are right.  I was throwing out rough estimates where i shouldnt have.  I do know that after the peak and clip mod I am running about 17 watt peak.  I know for a fact that the lower cbs like the cobra 29 are significantly less powerful than say a cobra 29.  thank you for clearing up my ignorance Truth.


If my thinking is correct, (and it may not be) If you are actually putting out 17 watts of power you would fry any radio receiving you. Somebody here linked up a pretty good site at http://www.rightchannelradios.com , and according to them all radios, even the ones that are peaked and tuned, put out an FCC regulated 4 watts of power.  The cheap radio you get at walmart, and the expensive cobra or uniden both put out 4 watts of power. Price nets you more features and thats it.

Ah! gotcha!

I will say though, I really want a noise canceling mic, but the radioshack one has a different plug than the ones im finding….

upgrading soon? I think yes!

I thouight about that for mine, but mainly because I have an open vehicle. But the second thought is my CB is pretty much worthless when I'm driving on the highway. Even when I had a top and full steel doors I could barely hear it.

i would gladly show pictures of my radio output if you would like, i will take a photo and post the result after i go to the cb shop to get a new mic. a radio that is peaked and clipped has the resistor limiting its output (put there by the fcc) clipped, taking the restriction off.  and having a high output would not fry another persons radio.  take a ham radio for example.  a ham or base radio has a very large output so it can cover a large area.

Electric stooge, i made a typo on the post you quoted, I meant a cobra 19 would not compare to a cobra 29 in terms of transmitting and receiving power.

Actually a boosted signal CAN fry a radio, but only if boosted way about where you have yours and ona power supply well beyond that of the average user.  Of course this does not mean that boosting a signal still is not going to cause problems.  With a boosted radio you are going to step all over other peoples signal and can bleed to other channels; do you really want to be the guy stepping on the broadcast of somebody who really does need help?

The FCC regulations are there for a reason…

A properly installed and tuned radio should get you around 5 miles of range and that is really enough for most situations where you are going to need a CB, beyond that you can relay stuff through other people.  Worse case if you feel that you may be farther out then that and your only way to contact others is the CB get an amp and use it only when needed but keep in mind that if you are boosting your signal you are not going to hear any response which makes the radio much less useful.

Base stations are, I think, still limited on power output; they get their range from antena hieght and size.  You ever notice base stations never have their power output listed in the specs?  It's because they are all the same.

HAM radio is a whole other beast and has less restrictions because it has it's own specific frequency range and requires a licsense to use.

I  hate to be negative but that's bunk. Not according to me, but according to the pros that sell these, and the manufacturer. ALL CB's have the same transmitting and receiving power. If they didn't they would advertised that way, and they're not.

Here ya go…

4 watts of transmission power. Price nets you features, not power.

at 17 watts you do not bleed over to other channels.  The only radios that I have seen bleed to other channels are the radios that have a "kicker" amp installed, I have only seen a 100 watt kicker amp installed so I am unsure as to exactly how much wattage will yield channel running.  Regardless, I am glad that you have done your homework, regarding fcc regulations anyways.  Anyways, it has been fun getting reamed over a couple watts.  :) Have a great 4x4 season, I surely won't be there, I'd hate to see what you'd have to say about my jeep after seeing what you guys did about a few watts.

Mitch I'm guessing by "the radioshack one" you were referring to the radio?  I have no experience with RS radios / their plugs, but if you do upgrade (we'll call this a upgrade for the sake of conversation) to a Cobra or Uniden CB, the "Road King" brand noise canceling mic is a excellent choice for either of those radios.

4x+ over fcc regulations is a little more than a few watts

if you over power a certain frequency, it will bleed into other channels, there is only soo much bandwidth

when you say "kicker" I think subs, and thats just a good back massage

I am sorry that you feel the need to leave the club, You seam like you are very eager to learn and try to teach others

Toliver, neither Dug, nor myself are members of this club.  So anything that I post here I don't feel is a fair representation of the membership.

My post to you wasn't to insult you, but to correct that two different models of cobra radios don't have different range capabilities. I'm sure the range on your CB is farther than most, but that's not what I was trying to correct. I'd hardly consider that a "reaming", so it's unfortunate you feel that way. Bear in mind when you post info anywhere people will fact check it, and more than likely correct you if you're mistaken.

I think it's odd anyone would leave a forum based on a couple posts that are in disagreement. So to make sure I'm not in disagreement with anyone else here, I'm going to have to stick to my guns this time and no longer post. Apologies for any misunderstandings.

Toliver,

I'm really sorry you feel reamed out over this but like Brandon said we where only trying to correct some bad information you had gotten.  I am no expert on CBs but I do know enough to see that you where working off of bad info and spreading it farther around.  FYI, all of my CB info comes from Chewbacca, a licensed ham radio operator, avid radio enthusiast and owner of one of the best sounding, legal, CB set ups ever.  With a un-boosted or clipped head he has been relay man both locally and on trips to Moab because his properly set up radio has better range than those of some people with boosted units.

I have to say it seems pretty silly to pack up your toys and go home just because somebody disagreed with you…  If you think we are wrong show us and I'll concede I was misinformed, findout we where right and take the chance to learn something.

The first step to greater knowledge is a willingness to listen.
