Topband: electrical QRM during contest!

[Gary Smith]

Did anyone hear massive QRM around 6:00Z during the ARRL contest last 
night? I've been trying to isolate a noise source but this was unlike 
than anything I have heard since the woodpecker and it had a fast 
attack like the woodpecker but was not the same sound. It extended 
into 80M as well and my local QRM I am DFing does not do that. When 
it started it seemed like the band activity dropped concurrently & I 
wonder if it was more than local.

Thanks
