[TowerTalk] HFT

[David Propper]

HI All,

just fyi,  Rhode Schwartz has put together an excellent presentation on the “re-birth” of commercial HF communications.  And yes, the stock traders are using HF to combat the lag time of conventional data networks.

73,
Dave, K2DP

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
