[TenTec] signal on 28.634 and other noises

[Jerry Volpe]

I hear the same signals here at my location (near Berkeley, CA). 
Although very interesting they are really only small disturbances 
compared to some other 'garbage' that I am trying to trace out. Others 
here notice the same disturbances so they are not local just to me.

3.543 MHz   High energy, short pulse width, static peaking here at S-7 
or more at night with a total bandwidth of nearly 15 kHz. It is present 
in the daytime too but not as bad.

7.084 MHz    (note the harmonic relationship). Same noise 
characteristics including intensity and bandwidth. Pretty much wipes out 
a lot of digital possibilities.

14,172 MHz   (as above). Same as on other bands with slighly less intensity.

This is really nasty stuff. Noise blankers will knock it down somewhat.

Anyone else hear this of is it local to this area?
