every night for the past 7 months i have been getting some kind of electrical noise in my radios here at the base.i get it on all 3 radios i use and the noise blanker and or anl switch does nothing.my antron 99 is about 12 years old but my coax is new.my question is.what can i do about trying to eliminate this?..i was thing about starting with getting a new antenna since my is about 10 years old.but if i get a new antenna and the noise is still there then i wont know what to do!..the noise gives me 3 pounds of noise when it comes in and i get it on most channels but sometimes its just on some channels then sometimes it moves from channel to channel..anyone know what i can do?i tryed to locate it with a walkie talkie and driving in my mobile but i cant find where it coming from.grrrr |

Swamper, have you been able to isolate what time it comes on? Does it not have the noise during the day/early morning when radio is quiet? It could be as simple as yours, or a neighbors night exterior light, especially if it's flourescent. If you can find times such as the day when it is not there, chances are it has nothing to do with your antenna. Think about these questions and try to figure out what time it comes on. Is it around sunset and/or same time each night?

Swamper, do you use a power supply?

well it seems to be more at night but im not on much in the day since im at work.but sometimes i do hear it in the day on the weekends when im on in the day.and no im not using a power supply.all the radios i use are base radios.if it is a neighbor with a flourescent light i still dont know how to get that sound out of my radio.i even called the local power company to check the trasformer on the pole near me,but they never showed up go figure.oh well maybe someday i will find out what it is.or just blow up the transformer on the pole..haha......j/k |

Swamper, we all suffer noise problems form time to time, that is the nature of wireless communications and you would just be lucky if you never noticed.
From your post it seems to rule out the antenna itself. Did it start about the time you replaced the coax or did you change the coax because of the noise?
You say you drove around with a hand held and you could not find the source. I guess that means you still had the noise, but you just could not find out where it was coming from, right? If so, then I guess raising or lowering the A99 would not help either.
Maybe you are just unlucky. The seasons are changing, so maybe your luck will too.

Swamper, I guess you know that some computers can cause inference on the CB band. Some of the ones in the 100-166-200 meg range are really bad. I've seen a 5 noise level from some of them. A loose connection on your outside transformer will also cause havoc, and will be worse in dry windy weather. As an electrican, I argued with power companys for years about this problem, finally came to this conclusion, if you tell'um its bothering a CB, they want help, if you tell'um its causing a 'white band' of interference on your TV when the wind is blowing, they will check it out. scrapiron |

Funny thing, my computer is pretty close to my radio.
One day it made me so mad I killed everything in my room one at a time and found it was my router.
It puts out a high pitch tone |

Swamper,
I had my Antron 99 since 1986, and a few months ago i had retired it, and replaced it with a new I-Max 2000. The new I-Max made a big difference in the static noise in my recieve, now it's very quiet. Also i used my old ground plain kit (GPK)from the 99 with the new I-Max 2000. All you have to do is put at least one inch of mast above the easy mount flange and attach the doughnut to the mast, then screw on the radials, center the radials around the mast, tighten the bolts on the doughnut, and your done. There is just enough room to do it. I did a check of the SWR before i put on the GPK it was about 1.4, and then again after putting on the GPK. My SWR is flat as a pancake thoughout the regular 40 channels, & i never touched the factory setting on the adjustable rings. You can do the same thing, and if you do, you will be a happy camper. Also make sure you have a good ground on your antenna, as static build up can cause a bunch of static in your recieve. Good luck and keep us posted. :-) |
