6400 Noise Floor

I have seen lots of questions about why the noise floor is about -110.  How do you lower it and is there a setting to make it better.  Note: My preamp/RFgain is not on.

    The best way to lower the noise floor is to move to some remote island where you are the only person and your Flex is the only electrical device within 10,000 miles. The radio hears what is there so go where it ain’t... the internal noise of the Flex is not worth mentioning

    Your noise floor is determind by your radio invirement. Some people live in a high noise floor and others in a lower noise floor. . We use the AGC-T settings, this makes the noise floor sound more tolerable.

    I live out in the country and the noise floor on my 6500 is -110. Nice and quiet.

    Fred-
    Thanks for the info, from your first post could not understand if you had a lot of antenna noise or the settings on the preamp was causing the high base line.
    8 ele log antenna probably has a lot of gain so sounds like everything is fine.
    If you rotate the beam does the noise go down? Maybe you are pointing at a noise source?

    Bill, yes part of my problem is some powerline noise and when I am 90 degrees to the noise it goes down significantly.  I have the power company tracking it down. I have been providing them with some data to help. They are supposed to dispatch a crew to correct a couple of transformers about a block south of me. I am hopeful that will take care of the issue. Thanks
