Just to add, it seems that I over extended the hf band the cut off as was
correctly pointed out was 30 mhz I believe.

And if anything since friday the vhf band seems improved, 2 meters has
been quite good.

I'd say that I have not noticed any disruption although I've heard tell of
disruptions in the gps network I haven't experienced them personally.
