Bob,
We spent the afternoon trying to characterize the pulses that I see here with my antenna pointed north. See my last plot for details:
http://www.juanr.com/pages/hobbies/ham_radio/Eagle/PAVE_PAWS.htm
You'll see several evenly spaced areas showing many hits over about a 30 minute span. They are too evenly spaced to be random but they don't conform to the PAVE PAWS band plan that I pulled from environmental impact reports from years ago. Because of the recent push to clear ham repeaters off of the air anywhere in the vicinity of a PAVE PAWS site, we know something has changed, but what?
To resolve all of our questions we'll need to move to an unobstructed location atop a local mountain and try again. That will take a few weeks. Until then I would be cautious about using my .wav file. It might be the neighbor driving around the block on his Harley.
73, Juan

Hi Dave,
I noticed that too. I killed the AGC but didn't think of the noise
blanker.
I'll take a look and try again if it was on. Right now I can't
communicate
with the CAN-Do module or I would switch to the 70 cm prototype receiver
and
repeat the test.

Yes, please. I have some interesting noise blanker stuff I want to work on to eliminate PAVE PAWS pulses on board the SDX transponder. This is the PERFECT set of signal collection (SDR-IQ of IF) for doing that work.
Thank you very much once again Juan for your extremely valuable contributions and your unbridled enthusiasm. It is very welcome indeed.
