Hello!
If these channels are used on indoor AP's, it would not be a very big problem.
But, these channels are allowed for outdoor AP's.
And that's the problem!
We have a central MSP customer, in the middle of an austrian City, operating an outdoor AP.
It took only two weeks after deployment until a radio measuring vehicle of the federal radio authority (I hope this is translated well enough) appears, and the customer and us got a warning.
We got a deadline to fix this, because we interfered with a weather radar (in austria, weather radar is starting with channel 144).
If not, there is a penalty.
So, it is very urgent to fix the DRT File.
We checked some IAP Clusters, it happens very often that the AP hopps to channel 149. Especially in the near of an Airport.
Now, the most of our Customers opperating outdoor AP's, are MM or Master/Standby Customers.
I have not checked them until now.
But I'm convinced that the controllers acting in the same way.
The "workaround" is, to overide the ARM channel selection by now.
But this is not a glorious way for us, because well known SOHO vendors do not interfere out of the box with our federal wether radar.
