Hello,
I have setup second ADS-B device and successfully claimed it.
But I don’t get a new SITE associated with the new device in my account. So, I can’t see its statistics and assign position for MLAT functionality.
How to add new SITE for account?
Under Dmitry Konnov ADS-B Feeder Statistics - FlightAware you should be able to select your sites. Click on the Chevron to see all your sites.
I have two running at the moment(Two are down)
Ahh. yes.
thanks, John for bringing my focus.
It first glance I thought there just 1 item in the combobox. The top one is colored differently, so it misleads.
I think you can have unlimited sites. I have 12 active ones under my account, and they just keep adding to the dropdown.
I agree, 17 sites and counting 
Anyone here who has only 1 site, and NOT counting?
I have two, but only because FA gave me a UAT FlightFeeder. If not for that I would only have the one I’ve had running since June of 2019.
