    Right Channel radio send me

    Right Channel radio send me this CB and it is amazing I had a few issues in the beginning with it but right Channel radio walk me through it and now I have an amazing set up

    Good radio.

    The Galaxy DX939 is a good radio foundation, over all. To make it perform at its full potential it needs to be tuned and adjusted by a professional technician. I see no purpose for the frequency counter, as there is no classifier to fine tune the frequencies, but I guess the designers thought that it would somehow help to sell the radio. I just installed it in my 18 wheeler, so time will tell just how good this radio is. I hope that it was worth the cost.


    Really love this! I have been a CBer since the 70`s. Had it tuned. Sound is crystal clear. No interference. Speaker is clear. Reaches way out there. Features and bells and whistles. Best warranty out there. Puts the other brands to shame. Check the internet for reviews and you`ll see. A beginner could use this.
