20 Most Recent Midland 1001Z 40-Channels Base CB Radio - Page 4 Questions & Answers

CB radios are AM radios operating in the 27Mhz band and are prone to noise even in home installation (though admittedly not as much). A signal on the meter that causes the indicator to move up to as much as 1/4 of the scale is actually pretty good for a mobile installation with the engine running. There are ways to minimize the noise, but none will eliminate it. Here are suggestions - in no particular order:

1) A well grounded antenna. Since you've got metal to metal contact with yours it shouldn't be a problem - the magnetic mounts are more prone to interference and noise that yours.

2) Locate the antenna on a large, flat, horizontal, metal surface. Mobile installs are always a compromise - but the more of these you can incorporate, the better the reception & transmission will be. There will still be noise - but when you receive better signals the "S/N" or "signal to noise ratio" increases - making the sound less noisy.

3) Tune the antenna for lowest SWR (standing wave ratio). You'll need an SWR meter to do this. Be sure to get one that will tune HF antennas - or at least one that works in the 27Mhz band. This is another method of improving the S/N ratio mentioned above. An untuned antenna can cause a transmitter to fail - so this is a must for any transmitter's antenna.

4) Obtain the power directly from the battery. Not the accessory terminal or battery terminal under the dash - but to the battery posts themselves. This is the cleanest (power-wise) source in the vehicle.

5) Install filter on the power lines feeding the radio. A rising and falling (with engine RPM) whine sound is usually alternator noise, and a popping sound is ignition noise. The whine sound can be helped by install a capacitor and the ignition noise by using an inductor or coil. So, if you have both noises, you'll need both filters.

6) Install resistor spark plugs and wires. Years ago, we had to get these as an aftermarket item. I don't know if those supplied by auto manufacturers are resistor types or not - so it may be worthwhile to check it out.

Some vehicles benefit greatly from one or more of these solutions, others - not so much. Some vehicles have noisy subsystems unrelated to ignition or alternator. Some tank mounted fuel pumps can be brutally loud and difficult to silence (check with radio on, and turn the key to run - the fuel pump usually runs for a few seconds - listen for static while the pump runs before starting). The vehicles that will probably have good luck are those that you see used as police, taxi and ambulance vehicles due to the radios and electronics in them.

I hope this helps and good luck! Please rate my reply - thank you.

Hi dm,
Welcome to FixYa.
My name is John. I will be assisting you with your issue.
Take the end of the mic. apart and check for a wire loose
touching another wire. Post back on reply.

try adjusting antina but you sould have a SWR meter you can buy just a meter then check it

if you dont know the culprit you are waisting your time

i know this sound daft but have you checked to see if the switch has been knock from cb to pa. it is amazing how people miss the smallest things.

the first button on the right hand side changes the fm to am but these usually break down. it is a small push button switch with four legs two at each side, but recomend sending it in for repair.

easiest way open mic the coloured wire on the wire at the front of switch is receive, the middle coloured one earth,and end colour transmitt,on the other side of switch is mic colour.find these out first then get back to me.

this is not common it only means you have a good ariel and ground.the preset for the squelsh inside the rig needs turning up if you really need to turn the squelsh off.

hi, chk fuse for outlet chk inline fuse for cb radios pwr cable . If you polarized the power cable wrong
there is most likely a protect diode inside the case that may be shorting out aswell

bad ground on antenna or radio if not grounded right will here lot of motor noise

yes but need to set SWR to antinna

Hi, my name is John. Try using a different mike on it. Make sure it is one wired for it. Sounds like it is in the mike area...let me know how it goes.hope this was helpful.Rate this solution on the four thumbs-up.........John

Hi erve, my name is John. Welcome to FixYa. You need a 2amp fuse, make sure you have the correct polarity, red wire (+) to the hot, and the ground (-) to the ground side. It is best to run the unit to the battery. If still no avail, let me know, I will have further solution. Thanks for choosing FixYa...John

This radio requires 12volt DC power and a suitable antenna.
It will work in your house if it is
A)connected to a suitable 12volt DC power supply with the wires the right way around (connecting the wires the wrong way around even for a moment will blow the in line fuse and the radio will not work until the fuse is replaced and the wiring is corrected, never bypass the fuse or fit a larger rated fuse).
B) connected to a suitable antenna.
If you like in a area where there are few CB radio users then the radio may work but there may be nobody for you to talk to. The local geography and how high up you can get the antenna will make a large difference to the range. The range will be much larger if you live on top of a hill than if you live at the bottom of a valley.

Hi sqa, my name is John. Welcome to FixYa. First thing to do would be is check your antenna system. Check that it is grounded good, like to the body of vehicle, and that nothing is blocking it. Next, check the coax cable, you will need a ohm meter to do this. Put it on the OHM scale, then with one of the probes, touch the center wire of the coax connector, while touching the other probe to the outside of the connector. If you get any kind of reading on the meter, the coax has a SHORT in it. If not, then the next step would be to check the SWR on the antenna. You can get this done at any locale CB shop for free. Try all these steps and still no solution, let me know and I will be glad to help you. Thanks for choosing FixYa....John

Hi my name is John. Welcome to FixYa. Turn the big dial to 26.965 thats channel 1. Thanks for choosing...John

Aluminum is a great conductor, and it sounds like your setup is just fine. Make sure that CB/PA switch is in the CB position. If it is, and you still don't hear any transmissions, chances are that there's just no one using this one-popular service in your area. I just tuned through through all 40 channels here in San Antonio, Texas, and didn't hear a single peep.
