Re: [WISPA] RADAR lockouts
I don't know the specifics, but all of the negotiations about changing the rules for 5.2 and adding 5.4 GHz was with the DOD, so I doubt those RADARs that you describe are the culprits.

RE: [WISPA] RADAR lockouts
I'm not sure the airport really means much- we have some 5.4Ghz deployed at several locations within 6 miles of Dulles and we have not seen anything yet.

RE: [WISPA] RADAR lockouts
They show up on the Spectras as 10 MHz.
