One had 3 big yagis, one was a big SteppIR by itself and the other had 2 big SteppIRs. All were pointed fixed east (I'm in the Seattle area).     Turns out that these are probably used in High Frequency Trading. That is, stock trading where fiber wasn't fast enough and the users have turned to HF to decrease the lag time. I thought it was pretty interesting and I'm curious how much this is being used. And at least they're not in the ham bands - hi.  Cheers,Steve    K7LXC

I'm surprised HF would be used - I've heard of old microwave links being 
reconstituted, but HF is interesting. HF trading usually focuses on 
getting to the computers in NY area. I suppose you could do that on a 
skywave path "sometimes".
