Infamous Channel 132 - 5GHZ in Canada

[RaphaelL]

Hi ,

I'm trying really really hard to understand why channel 132 in not available in Canada for my MR33/MR36 BUT channels 134 ( 40mhz ) and 138 ( 80mhz ) are available.

How can 134 be available when 132 in not available ? 134 will be using the 132 bands... no ?

MR33 : 

MR36 seems to follow the expected behavior :

I don't know the answer.

I see channels 120, 124 and 128 are not allowed in Canada (reserved for weather radar).

Could it be that a 40Mhz channel consumes channels (131,132), and the weather radar can also consume channel 131?  Or perhaps there is some kind of mandated separation?

Disabling random 20mhz channels does disable it's associated 40mhz channel. All except for 134... which I don't get at all. And only on MR33s... :

Template , non template , I have tried 'em all.
