Anyone know of a way to find out what freq a weather radar is operating on? I know of several local ones and would like to know what freq they operate on for safety sake. Any ideas? I've looked everywhere and found nothing?

IMO, it is "iffy" for the reason you mentioned. The FCC (at the request of the FAA and the NTIA) appears ready to deny use of the 5.6 spectrum in areas where interference with airport weather radar takes place. I doubt that any WISP would ague that their use of that spectrum is more important than safe operation of commercial aircraft. I expect that newly certified 5 GHz equipment will soon (within the next year) include a updated DFS algorithm that looks for the presence of 5.6 GHz radar and switches away from 5.6 when radar is detected. Your existing equipment may remain technically "legal" but you do run the risk of possibly being blamed for aircraft crashes assuming you are unlucky enough to be using 5.6 near airports where you could cause actual interference to Terminal Doppler Weather Radar systems. See <http://tiny.cc/LIlqB> for more information. jack Travis Johnson wrote: It's "iffy" because the FCC allowed the specific band, and now they are trying to take it back away... two years later. If I never upgrade my radios, does that mean I'm legal to run in that specific band forever? I just don't understand how they can allow it for 2 years, and then try and take it away and think they are going to clean up the airways.

I don't understand what is "iffy" about the band... Canopy operators have been using it for two years or so now legally, and while DFS still has issues in its current implementation, the FCC is working to make the DFS detection better on the radio side and in turn make it harder to radio manufacturers to allow clients to avoid using DFS Daniel White 3-dB Networks http://www.3dbnetworks.com -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Jack Unger Sent: Friday, November 20, 2009 11:02 PM To: WISPA General List Subject: Re: [WISPA] 5.6 GHZ? 5470 - 5725 is a legitimate band but DFS2 must be used on the radios. There is currently FCC activity to modify the DFS profiles for all newly-certified radios to avoid aircraft radar system in the 5.6 GHz part of the 5470-5725 band. The bottom line is - it's pretty "iffy". jack Forbes Mercy wrote: My new MIMO radios have 5.6 GHZ on them, I don't recall that frequency being available in the US. Is it?
