Even though 10-meter radios are illegal by FCC regulations, they are still the best way to go for talking on cb frequencies. There is a vast aray of 10-meters available, depending on what options you are looking for and how much you want to pay. In my opinion, the 3 best brands are Connex, Galaxy, and Magnum. If you would like addition information on any radios, lmk.

There is no factory made 10 meter CB Radio made for US use. CB Radios use 11 meters, and the FCC doesn't allow the combination of 10 and 11 meter radios combines. Although, many people modify 10 meter radios to work on the 11 meter ( CB ) band, it's not legal. Good Luck

How do I increase power output for a cobra 148 gtl the latest Chinese version


best way is to leave the radio in piece and obtain a linear amplifier to do the job a 10 meter ham radio amplifier will do nicely but you must re-tune it for the 27 mhz band 10 meter band is 28 mhz.
RF amps work best using side-band mode.

Purchased a midland 75 785 from u s will it work on u k channels


  • For 11 meter (CB) the standard 40 channels will be the exactly same as the "EU" set of frequencies (channels). However the "UK" 11 meter (40 channels) and the U.S.A. 40 11 meter (40channels CB) will not work together at all. This includes any actual Citizen Band radio, excluding Export 10 an 12 meter radios often labeled as "CB'S" which they are not.

  • Hope this helps.

How far will a cobra 19 cb reach


This is a tough question with many variables power, antenna, weather, terain, other radio traffic and interference on channel and reciever sensitivity.
The answer/guess roughly 2-8 miles depending on best and worse conditions.
This is one of your lower end cb radios but has a good receive sensitivity of the money.
This might be a good resource for any other questions you might have http://www.advancedspecialties.net/cb-radio-faq.htm

Be aware that most cb radios that Truckers talk on are actually 10 meter "export radios" that are illegal by FCC standards. They put out far more than the legal 4 watts that radios sold in the US as cb radios do. This is not to say that your typical cb is not modifiable to high rf power levels but not to the degree that the exports are.

Please explain a 10 meter am/fm radio


Okay.

You do set this up like a regular CB. The meters refers to how long the waves are. CB is 11 meters. So its very close. The antenna woud be tuneds slightly shorter. Use the SWR meter in the radio to calibrate just like you would a normal cb.

Now for the ABCDEF knob. each letter is 40 channels in the band. So A would be 1 - 40 channels, then B would be the next 1 - 40 channel frequencies. You use the frequency counter in the radio(providing that model has one) to tell what channel you are on.

Here is some info one the frequencies in the band.

Now for AM and FM. this is the type of modulation you are using for transmit and receive.

CB transmits on AM or SSB. Amplitude modulation or Single side band. Most CB radios only have AM. But some also have SSB. None will have FM.

FM is frequency modulation.

10 meter radios can have AM FM SSB and DSB depending on the model and options it comes with.

So your radio has 6 ranges for freqency. each is 40 or 50 channesl. Not sure what model you have. If it has 40 then you have 240 channel freqencies.

with AM and FM, you double that, because you can talk on AM or FM on all the channels. If you are on AM and some one transmits on FM unless they are really close, you will not hear them at all, but if you do with will just be garbbled noise.

Also Am and FM both work a little different with range etc.

Now, you may be able to talk on the CB channels as well. Cb starts at 26.965 MHz and ends at 27.405 MHz. The channels are all .010 MHz appart.

Hope this helps

Gtl dx will not transmit below 26.955


First off, the 200 GTL DX is a 10 meter radio. Running it on 11 meters (CB) is illegal, as it is not FCC type accepted. If you go below 26.965 mhz, you are outside of the 11 meter band, and operating illegally.12 meters does not start until 24.930, so ultimately, the freq's between 24.930 and 26.965 mhz are restricted even to a licensed amateur radio operator.

Information on how to use DX 45MP radio


The DX 45mp is a 10 meter radio meaning you need a license to use any other band other than the normal 1- 40 cb channels, its capable of going beyond the normal cb range.Ask if it has been converted to 11 meter. Channel E should be the normal if it has been converted from 10 meter to 11 meter. Im sure its been converted if its been used for a mobile cb application. Normal cb band is called 11 meter 26.965 mhz to 27.405 thats 1- 40 . Your not supposed to talk on the other bands unless you have an amature radio license but everyone does anyway . I have several galaxys and by far in my opinion are the best on the market. Go to www.cbtricks.com on the home page go to Radio Informaion click it go to G and follow it to Galaxy DX radios youll find all the info for this radio you can even print out the channel chart to see where everything is. Good luck and if you have any more questions just ask. Thank you Chia

Rci 6900f drifting


Since the RCI 6900 is a 10 meter ham radio, and not desogned for the 11 meter band, when you had it modified, you also expanded the PLL chip past it's normal use. 10 Meter radios are not designed for CB use ( and of course this is also illegal ) so the PLL does drift. There is no real fix on this problem. Sorry
