Subject: [WISPA] RADAR lockouts
What RADAR is on 5.2 GHz? This would be C band, I think.
I'm getting my first DFS lockouts and boy is it frustrating!
It is frustrating about the initial scan period and its frustrating when
channels lock out and disable.
It was frustrating enough to make me temporarily go back to 5.8, which was
a
pity due to the shortness of the hop (1 mile). I have the radios at 5dBm
and
still have a -59 at each end!
As soon as I can have enough time allocated to run to the other end (very
difficult access Govt bldg) in case I screw up, I am going to try with the
power all the way down.
The one end that looks towards an airport does get about 3 times the hits
as
the one looking away.
RADARs I can think of are:
Approach Control (not likely- I know where it is and its far away and on
1.290 GHz)
WX RADAR on a plane at the airport
WX RADAR at a TV station (most of them have pooled them or gone to a
service
or located them away from town though)
Airport RADAR - this is the one on the tower I think and is for the
ground
ops and close in stuff.
This airport is about 5-6 miles away. The most events (hundreds) are on
channels 116 and 124 with a few on the 50ish channels too.

PS- if you want to see what the bad news looks like when delivered, I have
