[TenTec] 40M Band Sweeps

[Paul Christensen]

> Is it limited to 7.0 - 7.3 MHz?

No, I now see that is it much broader than just 40M.  From my location, 
signal strength is about +35/S9 at any time of day.  So, it does appear to 
be some form of governmental or research-based chirping system as Stuart 
points out.  It also seems to track with such systems at 100 kHz per 
second -- just enough to be painfully annoying.

Perhaps my location is unusually sensitive to the sweeps, but I am a bit 
astonished that this deliberate interference is allowed to persist around 
the clock, albeit in short bursts.  No station identification seems to be 
required either.   Pretty amazing, but government organizations and the 
military seems to qualify for special exemptions from "good operating 
practices."
