What frequency is channel 21 on a cb radio? - Galaxy Radios DX-66V Base CB Radio

turn off the 10Kswitch

first , Is this a new radio ? If it is then send it back to Galaxy .Its under warrenty for 3 yrs.Second if its not then make sure you are on the cb band . it should automatically display the frequencies.

CB Radio Channels (FCC)[32] Channel Frequency Channel Frequency Channel Frequency Channel Frequency 1 26.965 MHz 11 27.085 MHz 21 27.215 MHz 31 27.315 MHz 2 26.975 MHz 12 27.105 MHz 22 27.225 MHz 32 27.325 MHz 3 26.985 MHz 13 27.115 MHz 23 27.255 MHz 33 27.335 MHz 4 27.005 MHz 14 27.125 MHz 24 27.235 MHz 34 27.345 MHz 5 27.015 MHz 15 27.135 MHz 25 27.245 MHz 35 27.355 MHz 6 27.025 MHz 16 27.155 MHz 26 27.265 MHz 36 27.365 MHz 7 27.035 MHz 17 27.165 MHz 27 27.275 MHz 37 27.375 MHz 8 27.055 MHz 18 27.175 MHz 28 27.285 MHz 38 27.385 MHz 9 27.065 MHz 19 27.185 MHz 29 27.295 MHz 39 27.395 MHz 10 27.075 MHz 20 27.205 MHz 30 27.305 MHz 40 27.405 MHz

• The UK uses more FM frequencies than AM frequencies. So the CB will work over there just fine but you will need to find someone who uses them frequencies as well or it may no be much fun. Here is a frequency chart for what we in America call import radios shipped from over there. http://macuk.org.uk/cbchart.htm 27.555 FM is the main frequency used in the UK but the Cobra 19 is a strictly AM CB. Also on the link on the far right are the standard 40 channel frequencies from the UK version of CB's and not one is the same as the Cobra 19 as the UK uses FM for their 40 channel CB radios.
• Here is the 40 channel CB frequency chart utilized in America http://www.csgnetwork.com/cbradiofreq.html
• Hope this clarifies things for you.

on the cb band (11 meters ) 27.105 is channel 12

CB radios and hand-held CB radios can operate on the same channel and be in contact with each other. Other hand-held radios do not operate on the same frequencies and even though they may have channel numbers the channels have different frequencies and will not operate to CB radios.

Thailand actually has three "CB" bands, the first is the same as the U.S. / CEPT (EU "European Community) band 26.965 - 27.405 MHz, the second is a 78MHz VHF mid CB band (I think its either 40 or 80 channels with FM mode) and then the 245.0000 - 245.9875 MHz VHF 80 channel band - apparently the law also stipulates that the 78MHz CBs must be yellow colored and the 245MHz CBs must be red colored.

But yeah, 245MHz Thailand VHF CBs are very illegal in the United States.

You can download a frequency chart at www.RadioReference.com hope this was helpful..

I am guessing that you are talking about getting it to talk on the FCC Citizens band. I am not too firmiliar with connex, but this will work with any radio with expaned channels.

Usually you use a frequency counter to see what frequency you are on when you are playing with the bands.If you do not have a frequency counter you can find the CB this way.

If its in a mobile, or you are not really far from a highway where big rigs travel, you can flip to channel 19 on the channel sellector then flip through the bands checking each time to see if you are on the CB 19. When you start to hear truckers or you get a radio check from a trucker your on CB 19. You can always ask the person, "this is 19 right"?

I recomend geting a frequency counter.

To add 10Khz to your transmit frequency:

FIXED/OFF/+10KHz SWITCH: The left position puts the radio on
one of the three fixed channels that is selected by the channel switch
(6,19, or 21). This over-rides the channel selected by the 40 channel
knob. The right position adds 10KHz to whatever frequency you are ON.
In the middle, both features are OFF.

Otherwise, a radio tech would be able to retune the frequency inside the radio.

After adding 10KHz to your frequency, use the SWR control to check the SWR of your antenna.
Here's how:
SWR CAL CONTROL: Normally this switch is set to “PO”. Then,
during transmission, the meter indicates output power. To read SWR,
rotate this knob during transmission until the needle moves to the “SET”
point on the SWR scale. Then, while still transmitting, set the R.B./SWR
switch to SWR.

Ideal SWR is 1 but you'll want to be as near one as possible. An SWR of 1.6 or greater will make ineffective use of your antenna.
If in doubt, a radio tech has the required meters and tools to adjust the SWR/Tuning of your antenna.
