    Hi Jose,
    I'm interested for your modification on a cobra 148GTL cb radio which can give 26.965 - 28.045 mhz after adding the MB 8719 transistor. I seek assistance if you could advise other modifications which could give you a freq range from 26.965 - 27.995 mhz. This range is allowed in our country to use so please could you assist on that.

    All the best

I have recently bought a new Cobra 29 LTD BT(new) from the USA not realising it was 27MHz? Does anyone know if you can get them changed to 26MHz? Or does anyone do it? I'm a truckie & would li


It is stuck on 27 by design and FCC rules--those almost never will go down to 26 and if did would require extensive retuning to receive and or transmit there----sell it if you need 26 and buy a Ranger or Galaxy instead.

I have a cobra 29 brought in us want to change to newzealand frequency


Normally this would not be possible, but to do what you are proposing you would be hard pressed to find anyone that could do this. The us radios have built in diodes to trap out frequencies to keep them in the 27mhz bandwidth, so you need to find someone who knows radios inside and out with the proper circuit diagrams to work with.

Nice choice of radio i have the Grant LX Uniden which is roughly the older version.
This site may be of interest also if you choose the channel mod make sure you have the right PLL. http://www.radioaficion.com/HamNews/mods/mods-cb/2428-uniden-grant-xl-mods-pll-agc-power-clarifier.html

How do I get back to regular CB channels on the 75-822? All I can get is 27.xx and 26.xx. Where are the 1-40 channels.


I'm guessing that you bought the CB from a person not a company the CB band is between 26Mhz and 27Mhz unfortunately your CB was Modded to talk on Ham radio frequency's what i would suggest is one of two things if you are good at electrical soldering get a schematic and take out the mod or look on-line for a ham radio store like ham radio outlet near you and see if they can un modd it.

if you bought it from a store return it or talk to midland to see if they can fix/reset it at http://www.midlandradio.com/Contact-Us

one other thing until the radio is fixed it is not FCC part 95 or 97 compliant and is therefor illegal to transmit with it

North Star Dx440v


Hi and welcome to FixYa,

Enabling the 25.165MHz - 28.755MHz range of the radio would require modifications. Depending on the version of the DX440V, here or here. Incidentally, the Channel Chart is here.

Good luck and thank you for asking FixYa.
