    Ez money, when I bought the radio from the cb shop they put the channel kit in it, and said they was going peak and tune it, didn't take him no time cause I was standing there waiting on him. Now if he really did peak and tune it cause I'm really not sure of everything involved, or how long it would take? I'm taking the radio and amp to a cb guy that I've heard nothing but good things about.

    Uti transport, that's what I'm worried about! I've learned some pretty good lessons the hard way tho, and pretty sure there will more to learn, lol

    Thank you guys for your input and advice, hope to be heading to the cb shop here in a bit when I get off work, I'll be sure and post what the problem is
     
    UTI TRANSPORT Thanks this.

    When you get everything set up perfect, it will help. When you turn on your amp things will be a little bit better local talking, but probably NOT what you are thinking. Most times you can talk better at 1,000 miles away but, not much better at 10 miles. Hope that makes sense. Alot tired and a lil alcohol at the end of a rough week :biggrin_25525:

    It takes just a few minutes to tune one.A couple turns of a screwdriver and maybe clip the limiter.

    To do it right it needs to be put on a scope,everything adjusted and aligned then checked on quality equipment.
    AND the limiter not cut or the coils bent open.....
    So many hack shops do just that and call it a peak and tune.

    Hopefully the Tech has an oscilloscope to be sure the signal is clean and not splattering all over the band.

    Take the radio and the amp to the CB shop so they can match them up.

    I have a single final Galaxy 44 that i use with a small amp.
    On a good day 30 miles.
    When skip is rolling i can talk all over the US and as far as Puerto Rico.

    Also that amp needs 25 amps of power to run correctly....Did you use heavy wire and power it direct to the battery?

    Yep didn't take him long, he said the dk was a little high on the low setting, so he set it to about 2, said the amp had some kick for what it was, but said he couldn't get close to 250, he said all he could get was about 150, which doesn't surprise me, as usually anything like that is a Lil over exaggerated. Haven't had a chance to really play with it yet, but I'm kinda thinking it's gonna more like Kak was saying, not sure it's gonna be quite what I was expecting, but I'm gonna play with it and just see.

    About 6-7 miles. Well, maybe 7-8 miles. Propagation theory for line of sight transmissions (what we are discussing here) are not dependent on power for range calculations.

    What adding power does is adds a little "headroom". When the signal gets down in the noise to the point where it's hard to copy, an amp will bring it up out of the noise a bit. It'll still be noisy.

    Thank you for that msjamie, that kinda put it more toward the answer I was looking for, what little I did play with it on the way home, that's exactly how it was.

    Ez money, it's straight to the battery, 12 gauge wire, you think I might should change it up to 10 or heavier?

    Well let me add, it's 12 gauge wired straight from the battery to the radio, but I spliced into it for the amp. Should the amp and radio be wired separately straight to the battery?

    Yes, you want to run the amp right off the battery.

    12 gauge wire is kinda small...I would go with at least 8 or 6 gauge for the amp.
    Most car stereo shops sell it by the foot.
