Attached is a Matlab plot of Juan's SDR-IQ PAVE PAWS capture...
In the plot, you can really see the noise-blanker suppression after each spike...

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.
