*CB Frequencies!*

Many people have asked me for a listing of CB channels and the REAL frequencies that they represent. There is this little clause in the Ham rule book that says people with ham licenses can build their own equipment if they are licensed to be on the frequencies they make. Seeing this, many people found out that the older General Electric and Cobra CB radios with the Phase Lock Loop (PLL) Chips (like the PLL 02A chip) could be easily modified in about 10 minutes (with no additional cost or parts except 3 "on/off switches) to reach these (and other) ham channels. If you don't have a Ham license then modifying your CB to go "out of band" is VERY illegal!!!!! In some foreign countries where there are little or no radio restrictions, many of the people who live WAY out in the jungle or bush modify these inexpensive radios so they can talk further and on channels that are less cluttered than regular CB channels. This also cuts down on the chance that they will be monitored by their neighbors, or guerilla soldiers, who may be listening in on "regular" channels.

CB radios operate in the 11-meter band. When people think of Ham radios they think of 2 meters (mostly radio phones tied to "repeaters") and 10 meters... The 10 meter band can be reached with a simple mod on these radios and many "jungle dwellers" do just that.

For those of you who asked for the channel/frequency list...Here ya go!

(OOOPPPpps... I forgot that CB's only go up to 40 channels huh? How silly of me....)

Notice that after channel 25 all the frequencies follow the channel number at the 3rd and 4th digits IE. Channel 26 is 27.265 and channel 40 is 27.405

Want side band? Sideband variations are +.001 (upper sideband) and -.002 (lower sideband) from center of frequency, IE. Channel 40 upper sideband would be 27.406, whereas Lower sideband would be 27.403 (another simple mod to add).

Hope this helps you guys out.

(Warlord's note: I came REALLY close to drawing up a schematic showing how you ham people could convert these radios (since it is VERY simple) and posting it on here, but I am not sure of the legalities of it... If someone convinces me it would be legal for educational purposes, I may just do it.)

Aww Screw it, here it is:
