"Does Homeland Security OTHR Affect HF?

This past weekend, '9-11' 2005, several of us in the central Texas area heard unusual pulsing or popping signals on the bands, especially on 7 MHz. I had a QSO with a Oklahoma station on 7 MHz Sunday evening who had just talked to a Florida station about the same thing, and both had also heard such signals.

The fellow in Oklahoma thought it sounded a lot like the old Russian woodpecker (over-the-horizon radar). If I hear it again, I will try to record it, but it did sound at least similar to the old woodpecker.

At first I think we all worried that BPL was revenging us already, but could we have heard The Relocatable Over-The-Horizon Radar (ROTHR) for Homeland Security described in this Raytheon pdf brochure?
The AN/TPS-71 ROTHR is also discussed on the Federation of American Scientists' web site. "

Code may be taking a back seat for now,
but the pioneering spirit that put the code
there in the first place is out front of it all.
