Interesting - the email I just received.  It starts by saying "we apologize" for this email being late.  It then goes on to say that since I am not within 1 KM of a power line using PLC, I am authorized to use 630 and 2200 meters.  Okay!  Meanwhile, I think by law they had 30 days to reply after which I was in the clear and they missed their date....but why push things?

I urge everyone to send in the permission email.  Even if you never plan to operate there:
1.  You might change your mind.  For FT8 lovers - this is new fertile territory.
2.  The more permissions granted the more we "lock in" those bands for our future use.
