There are line filters that can be installed on the AC wiring. The most available is either a surge protector with line filtering or an UPS with line filtering. Of course a lot of the static is "airborne" and will be entering by the antenna. There is not much you can do about that.
You say he can turn circuits on and off in your house. What type of remote controls do you have installed in your house?
The garage door problem is easy. The early remotes only required radio carrier which weren't that many allocated so by trial and error it is easy to identify. The current remote openers on the market require codes and there are millions of possibilities. You can buy just the remote transmitter and receiver and replace what you have very easily. That will put an end to all of the fun that he is having!

CP185 has intermittent static, when pressing button to talk screen displays "channel busy" and battery will not keep a charge.


Could be one of several issues. A few which come to mind are:

1) You have a bad or poorly charged battery. Static is a sign of a bad or poorly charged battery. Try swapping a battery from another radio, with a known good battery and see if the problem is solve. If this resolves the issue check your battery and charger. Tip: Clean all charge contacts with a pencil eraser to ensure good charging. Also, check your 3- or 4-digit date code on the battery. If more than 2 years old, replace the battery. (4-digit date code example 1303 would be 2013 the 3rd week; on 3-digit date codes the first number is the year and the next two the week of the year.)

2) You are trying to use the radio in an area where you are experiences high RF on your frequency. This is the "busy"... someone/something is on or near your radio's frequency and interfering with transmission. Try your radio at a different location and see if the problem persists.

3) Another radio in the workgroup is stuck in transmit, causing static, and the channel busy. Turn off other radios, one at a time, and see if the problem still exists.

4) Or if you have an audio device plugged into the radio, try unplugging it and see if the problem stops. FYI: All audio devices must be plugged or unplugged with the radio shut off. If you plug one in with the radio turned on, you can experience some unexpected intermittent issues.

If none of these seem to be the problem, your radio is likely in need of repair.

Best regards.

How do i stop the intermittent static?!


Static can be caused by a poorly charged or bad battery. Try cleaning your battery contacts with a pencil eraser, on the battery, radio, and charger. Then recharge the batteries and see if the problem still exists. If so, try a battery from a known good unit and see if it stops the static.

If the battery is not the issue, you could simply have environmental noise. RF (radio frequency wave) in the environment is a common problem in urban areas. If you are using the radios in or around computers and other electronic devices, coil the cords to these devices and make them tidy. RF noise can be emitted through the cord like it is an antenna of sorts. Coiling will reduce this effect.

If your radios have PL capability, aka private line code, interference eliminator, turn it on, or change the setting. This should block out unwanted noise and interference.

Best regards.

Mag One Radio - Static


If your BPR40 radios are all about the same age, it could be a sign of your batteries getting old and needing replaced. A bad or weak battery will cause the radio to exhibit static, and then eventually poor or no transmit. Check your battery date code first, it is a 3 digit number on the battery label, followed by a space and then usually a number 1. On the 3-digit code, the first number is the year, the next two the week of the year. 229 would be 2012 the 29th week. Replacement batteries should be available for around $35.

If you feel the battery is not the issue, you may have ONE radio which is causing the problem. Try using all your radios and testing by shutting off just one radio at a time. You may identify the culprit. Motorola offers a one year warranty on the BPR40, after the warranty is done, flat rate repair is typically available for $69.

Third possible cause is some type of interference in your area. If this is the case, your radios may need a PL code programmed into them, if you don't already have one. This will filter out unwanted noise or transmissions. Sidenote: If you've added any new computers or electronic office equipment recently, it may also interfere. Some foreign produced computers will lack the filters required in the USA to prevent interference with communications. Coiling excess cables can be helpful in stopping RF noise.

The second of static at the end of your transmission is called "white tail" and is common in all modern radios. There is a programming feature to eliminate most of the white tail noise, it is called reverse burst. Your radio dealer can reprogram your radios and add this to your radios, or future radios you buy. The trade-off with reverse burst is that you will loose the last of your spoken words if you do not hold your PTT an extra moment, as reverse burst actually transmits back or cuts off the end of a transmission to eliminate the noise. White tail is worse when mixing old model and new model radios together.

Best regards.

One of my radios keeps emitting a constant static, whil the other work perfectly. Help?


Contant static can be a sign of a bad battery. Try trading the battery pack between the units to see if the problem moves to the other radio. If so, you need to replace your battery pack. Any other problem related to static would not be able to be resolved, as the T4500 is non-repairable.

Best regards.

Just bought a car and it had hardwired sirius radio already installed. I called and activated it with Sirius radio and tried to get assistance from them on how to get it to work. They gave me instruction...


The "hard wired" version that you speak of apparently only refers to the power supply.Do you have a seperate display for the Sirius unit? Now, you failed to mention the type of radio (factory or aftermarket); so, if you have to use an "empty radio station" then you have an FM modulator. This modulator could wired or wireless. The wired version interrupts the vehicle antenna wire and the station on said modulator is usually preset to either 88.1, 88.3,88.7, or 89.1. There is no need to power this modulator up, it comes on when then Sirius comes on. One way to check for power is to turn on the Sirius unit and tune your radio to an occupied Fm station. Wait a few seconds and listen to the reception. Turn off the Sirius unit, the reception should improve for the occupied station. If it is a wireless FM modulator it also has preset stations that you can change but, extending the wieless antenna will greatly improve your reception of the Sirius stations.

Hyundai radio CODE needed


I believe that these older HYUNDAI radios use a hardwired code system  inside  the radio.

The only place I know where you can obtain FREE advice and a FREE code for thesew old Hyundai  (if it is a hardwired version) would be here

www.ukbookshelf.co.uk

Mention this forum.

If it is not a hardwired code , then you will have to take it to a Decoding Service who will have to plug in a laptop to read/recode the memory chip

I get static after someone else talks


One of the main causes of static can be a bad battery. If you are using rechargeable batteries you need to replace them every 14-18 months. If you are using alkaline batteries, they have been known not to fully power the radio once your cross the 10 hour mark. Your radio would then be operating in somewhat of a brown out. This would lead to static.

Another cause of static is simply being nearly out of range of the other radio(s).

The burst of white noise at the end of Rx on some radios can be rather annoying. On the basic talkabout radios there is nothing which can be done to solve the problem, other than replacing the radio.
