I was "stopped" by some FAA tech ops guy back in my college days for bleeding over on the tower frequency near MLU. Nothing ever came of it. I told him I was a pilot too and would be sure to turn off my amp when near the airport. I was running a big radio with about 350 watts of bonus boost.

The FCC has much bigger things to worry about than someone with a CB and amp chatting it up on the trails/hiway, unless they are getting many complaints. 20 watts won't even get their attention.

County98 If it's really vehicle noise, it will be a whhhirrrrrring sound that changes a little with vehicle rpm. Will be there always regardless of any static or other stuff. if so, probably a bad ground. make sure you sanded any paint off of all your grounding points. might help I think.

If you buy your SWR meter from Radio Shack, you will need to also buy a short cable to hook it up. Doesn't come with the cable. Least mine didn't.

Jag I had a ton of vehicle noise that was the result of an improperly installed antenna stud which was shorting the thing out. Might be worth checking.

Standing Wave Ratio. You need an SWR meter and adjustable antenna.

Perhaps this will help: CB Radio Articles: Selection | Installation | Troubleshooting

Rooster76 I'm not sure about noise. Running power to the battery was a good idea to stop engine noise. If you have an ANL (Automatic Noise Limiter) on your CB i would try turning that on. My super basic Uniden 520XL has one so you probably have one too.

To get better reception your best bet is a longer antenna. That's a huge factor. I think the firestick FIREFLY (not other stiff models by them) are the best. You can get one 4' long and they bend like 90 degrees. You don't really need a spring with them.
For best performance you want:
-It as high as possible
-As long as possible
-And at least 1/3 of the length over the roof line.

Which CB radio will give me the best range?

All stock CB radios are limited by FCC regulations to 4 watts of transmission power. Accordingly, all radios will have the same output power regardless of their price. As all radios are limited by this bottleneck, the largest determinant of performance is antenna quality and installation. We’ve written an entire article that discusses antenna and mounting location selection which addresses important factors for getting the best performance possible from your CB system. This article is titled Choosing a CB Antenna.
Here they give you some numbers CB Radio Range Approximations | Right Channel Radios Of course in hills and trees it's going to be a good amount less.

Single Fiberglass Antennas
  • 2' Length: 2 to 3 miles
  • 3' Length: 3 to 4 miles
  • 4' Length: 4 to 6 miles
  • 5' Length: 5 to 7 miles

There are places that can "Tune" your CB. Usually truck-stops from what I have heard. Basally they can make your CB transmit higher than the legal FCC range. I personally don't think that it would be necessary, and is more a trucker thing to do. Also it can annoy others by having too strong/loud of a signal. It seems like the Galaxy are one of the more "tune"-able cbs from the threads I have read though.

You need to tune your antenna's SWR if you haven't already.It can destroy your radio if you broadcast skipping that step, and you'll get bad reception.

Good Luck

CB install.

I just completed my CB install (Galaxy DX 949). I routed the coax to the rear of my rig and mounted the antenna to the rear left of the gate, right side of tail light. The power cable is routed through the fire wall to the battery to alleviate vehicle noise. Only problem is, I still get vehicle noise. Is there anything I can do to stop this? i have a low pass filter and wonder if that will solve it? Also, any recommendations on what I can do to boost my power to get out further? Any and all advise will be taken into consideration, as I am new to all this. Thanks in advance!!
