FEDERAL COMMUNICATIONS COMMISSION
FINDING YOUR EXISTING UNICOM LICENSE

If you already have an FCC Unicom Station license, to get a reference copy

To begin, click this link   FCC Advanced License Search

From within the window, select MATCH ONLY
and from the pull-down "AF," to limit the to "Aeronautical Fixed"

Then proceed directly to searching by location,
clicking on the link on the bottom of FCC web page

In the next page, I just enter the zip code of the airport location
For some unknown reason, with 1 km it cannot find the licenses, but 4 seems to do the trick
I leave it kilometers because it is one less click, and it makes the Belgians feel good.

Then, once again,  hit 

It will seem as if the FCC system has hung, just wait. 

Eventually you will see a listing of stations for that location 

Next click on the FCC ID (which has no relationship to anything else in the universe)

Then click on Reference Copy  to get a PDF link for your license

And PRESTO, there's your reference copy!

Wasn't that easy, intuitive, and straightforward?
