    I am running on a A99 antenna. I am getting about a S7 on 10 through 15 meters , and others. 20 Meters quiets right down. Also 40 is quiet. Not talking on 40 with this antenna just for testing purposes. My 2 meter hand held also is very quiet also not going through the A99.
    I also notice the noise seems worse on SSB than AM. If I am on 10 meter and switch to my 6 meter antenna the noise goes away. I tried tracking this down with a AM radio and a hand held but really find no transformers near by where the noise gets worse. Could this be a antenna problem?

    Have you tried running the radio on just a battery and switching off the power through the circuit breakers?

    Also the farther away from resonance you get the less noise and signal is heard.

    I am going to try the battery next. I went out with a AM transistor radio and found 2 transformers on poles that show a bit more noise.

    Aluminium 5/8. Sirio 2008 or similar. Proper grounding and choke baluns are essential too.

    Is your radio capable of going mobile? If so put your radio in your vehicle and drive around the neighborhood. If you find a house with high noise levels DO NOT make contact! It could be a grow house for "Herbal Incendiaries". As you drive around when your noise goes up take notice of telephone poles and transformers. If you can map out the locations and when you call the power company you can give them a copy of your area test. They will then know you did your homework and then they have to do theirs. They will still do their survey and likely discover any grow houses in the area and fix all of the insulators and transformers.
    They are required by the FCC to investigate all radio noise complaints.

    Are you capable of stringing up a horizontal of any kind?

    Unfortunately my new pick up is aluminium and slapping on a magnetic antenna on it is not too easy, a idea i have thought of.
