Every day around 22z - 0z and 10z - 12z my CPU starts working a little harder.  At the same time the noise level goes up around 6db and my monitoring sees fewer planes, etc.\r\n\r\nIs there a connection?  Does the CPU go up because the noise has risen or is the noise an artifact of the CPU?  I don't know, but found it curious.\r\n\r\nNone of this would have been possible to notice before this wonderfully high res graphing.  I have already used it to find a sweet spot for my indoor antenna.  A few inches can make a huge difference.\r\n\r\n![ads b feeder performance graphs](https://cloud.githubusercontent.com/assets/3851061/13200605/3c5fabc6-d805-11e5-9f3a-7b0eb6bdf09b.png)"},"comment":{"url":"https://api.github.com/repos/jprochazka/adsb-receiver/issues/comments/187514848","html_url":"https://github.com/jprochazka/adsb-receiver/issues/103#issuecomment-187514848","issue_url":"https://api.github.com/repos/jprochazka/adsb-receiver/issues/103","id":187514848,"user":{"login":"geofffox","id":3851061,"avatar_url":"https://avatars.githubusercontent.com/u/3851061?v=3","gravatar_id":"","url":"https://api.github.com/users/geofffox","html_url":"https://github.com/geofffox","followers_url":"https://api.github.com/users/geofffox/followers","following_url":"https://api.github.com/users/geofffox/following{/other_user}","gists_url":"https://api.github.com/users/geofffox/gists{/gist_id}","starred_url":"https://api.github.com/users/geofffox/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/geofffox/subscriptions","organizations_url":"https://api.github.com/users/geofffox/orgs","repos_url":"https://api.github.com/users/geofffox/repos","events_url":"https://api.github.com/users/geofffox/events{/privacy}","received_events_url":"https://api.github.com/users/geofffox/received_events","type":"User","site_admin":false},"created_at":"2016-02-23T03:53:36Z","updated_at":"2016-02-23T03:53:36Z","body":"I will observe for a few days.\n\nIt is cool to hear a copter fly overhead, look on the computer and know who\nit is!\n\nOn Mon, Feb 22, 2016 at 7:46 PM, Joe Prochazka <notifications@github.com>\nwrote:\n\n> Yeah looks like dead times for the most part just the huge spike in\n> outgoing bandwidth dropping down to not near as much that you pointed out\n> which has me scratching my head and why I was wondering if something else\n> was installed which was kicking off at those times.\n>\n> I would say if it is a clean installation with only the software installed\n> by these scripts give it another day and see if the spikes happen again.\n> Maybe something downstream having to do with one of the aggregate sites?\n> not sure...\n>\n> —\n> Reply to this email directly or view it on GitHub\n> <https://github.com/jprochazka/adsb-receiver/issues/103#issuecomment-187512326>\n> .\n>\n"}}
