That is wrong , I used to have a freq. counter that only read when you applied RF to it on my old Tempo rig and I ran lower 37 and upper 35 so I would key the radio on am and tune the vfo to that frequency and would be on frequency with everone else,I remember hearing that once long ago but it's not true.

    basically, an AM signal is composed of a carrier signal, an USB and a LSB. If you delete the carrier and (say) the LSB you are left with the USB which occupies from the carrier frequency UPwards to the limit of your audio signal (lets say, 2.5Khz) so your signal goes from 27.185 to 27.1875 (ie. 27.185+2.5Khz). On LSB your signal would occupy the slot 27.185 to 27.1825 (ie. 27.185-2.5Khz). On AM your signal occupies from 27.1825 to 27.1875 or about 5Khz, Thats one reason SSB is more efficient and quieter than AM.

Can't get freq numbers and channel numbers to match on dx66v


so,what numbers does it show? If you are at 27.187 or 27.183 it should be no problem that little amount of frequency differance won't make any differance. Now if you were at 27.180 or 190 then you would be going into another band width.

How to use ssb usb am cb radio


  • Well, AM is Amplitude Modulation and Sideband suppresses the carrier and uses only the top half (upper sideband) or lower half (lower sideband) of the wave.

  • Whether using AM, USB or LSB you are on the same frequency although if someone is on USB and you are on LSB you will not be able to understand what the other person is saying because you are using different parts of the wave. So 27.185 (channel 19) on AM, USB or LSB is still 27.185.

Looking to find the frequenecies of the upper and lower channels



  • Hi I can help.
  • For the Grant 40 channel CB there are 40 frequencies I will list below.
  • When you refer to the upper and lower channels for this raidio you must mean USB (Upper Side Band) and LSB (lower side band).
  • This is called single side band modulation which is to say the the carrier is removed from the upper or lower sideband depending on which your pick and the signal goes farther on less power.
  • So the upper and lower side bands are the same frequency just upper side band or lower sideband.
  1. 26.965 MHz 21. 27.215 MHz
  2. 26.975 MHz 22. 27.225 MHz
  3. 26.985 MHz 23. 27.255 MHz
  4. 27.005 MHz 24. 27.235 MHz
  5. 27.015 MHz 25. 27.245 MHz
  6. 27.025 MHz 26. 27.265 MHz
  7. 27.035 MHz 27. 27.275 MHz
  8. 27.055 MHz 28. 27.285 MHz
  9. 27.065 MHz 29. 27.295 MHz
  10. 27.075 MHz 30. 27.305 MHz
  11. 27.085 MHz 31. 27.315 MHz
  12. 27.105 MHz 32. 27.325 MHz
  13. 27.115 MHz 33. 27.335 MHz
  14. 27.125 MHz 34. 27.345 MHz
  15. 27.135 MHz 35. 27.355 MHz
  16. 27.155 MHz 36. 27.365 MHz
  17. 27.165 MHz 37. 27.375 MHz
  18. 27.175 MHz 38. 27.385 MHz
  19. 27.185 MHz 39. 27.395 MHz
  20. 27.205 MHz 40. 27.405 MHz.

Galaxy 99 has same frequency 27.185 on am also on upper side and lower side band how come?? thank you


The frequency doesn't change when you change to USB or LSB. Basically the AM frequency takes up a certain amount of space, known as bandwidth, so it could fill in for example use 50 hertz above and below 27.185 giving 100 hertz bandwidth. When you use sidebands the am bandwidth is split in two so the upper side band would use the 50 hertz above 27.185 and the lower side band would use the 50 hertz below. The idea is that twice as many operators can operate without interference.

In Thailand Cb radio users must use freq range 245.000 - 249.999 freqs. Do usa Cb's use this freq?


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.

U mean on sideband? Frequency counter only useful on other than sideband operation. This does not mean the carrier insertion osc. is on frequency. If it needs adjustment, your voice will sound high/ low on transmit. Incoming signals will sound right after adjusting the osc.

Scanner(POLICE) Question


Hi, using the manual button, step to channel 1 and enter your freq. including the point then press the E button. You might have to step to the next channel using the manual button again. Enter the next freq. and repeat. WX is the weather bands. Lockout is for locking out a nuisance channel(as an example, if someone's mic stays keyed, and keeps the squelch open).Priority is for any channel whose conversations you don't want to miss, just press the button for the specific channel. That way any time someone keys up on your priority channel, even if it's on another channel talking, will go right to the priority one. Review gives you a readout of the freq you programmed into a specific channel. If you need new or extra freq's check here on this site.

Cobra 148 gtl new model


Hello bluzfan, Do you remember the old 40 channel CBs? they used basic A3A transmission (dual sideband single carrier)remember how you got crosstalk sometimes, if your power was too high? Then they went to 80 channel CBs (using a single side band as Lower Side Band (lsb) and the other as the upper side band (usb))? more crosstalk but they invented anl (automatic noise limiter)circuitry to compensate. Now you have the 120 channel CB which uses a form of side band multiplexing (20QAM) to generate 3 times more channel density 40 X 3 = 120. Here is my problem; Cobra should not have done this because you will have massive crosstalk and unaudible sounds because of the increase in channels but not an increase in initial (physical)bandwidth. I hate to tell you this but the only cure for the is to use it in 40 channel or 80 channel mode forget the 120 channel mode, or get a radio with better channel separation.
