Is my ADSBx feed live?

Hello I'm new here.
I think I'm probably feeding, but not showing up as a marker on the map.
My local area is changing from red to green, have I missed something, or does the update process take a while?
I'm on my test system with the antenna indoors at the moment, so not seeing many aircraft, but MLAT is working from PiAware.

Also http://adsbx.org/sync

 

It took a while to show up, but now working well with external antenna.

 

Yea that map updates every few hours.

It's best to use.

Can I run two feeds from the same site for experimental purposes?
Do they show up correctly or does it confuse MLAT?

 

Just be sure to give it a different mlat name.
