Peter,
The other signals you have heard in the 70 cm band seem to be similar in
description to signals heard here in the Upper Midwest shortly after 9-11.
A number of us in a wide area (large portions of MN, IA, WI, IL, MO) have
heard those sweeps multiple times. One ham made a digital recording, and
Ed, W1RFI, posted that in an earlier message. In general, the signals
sweep from about 430 to 439 MHz. I am not aware of the signals (presumably
radar) going above 440 MHz. As you may recall, the AWACS aircraft have
been pressed into service in a "border patrol" function, and those aircraft
have a lot of radar aboard.

Dale et al,
I looked around 433.92 MHz in my area and so far I've seen about six very
low level signals approx. -110dBM with very short duration bursts.
I listen to 432.100 MHz in the shack extensively and never noticed them in
this area. I do often receive a signal here on the Jersey Shore that runs
from S1 to 30db over S9 sweeping across a broad range of frequencies. It
sounds like some type of alien attack ( best guess it's military in
nature).
One day I'd like to find out exactly what it is...
