Topband: RADAR or whatever

[Tom Rauch]

Ken K4ZW was nice enough to send me a file of the QRM.

Unfortunately it looks like I either need a much wider 
bandwidth file or an oscilloscope snapshot  of several 
pulses with very wide bandwidth (perhaps 100kHz).

I need a time-domain picture of the waveform through a very 
wide filter to see if it is blankable. Right now it looks 
like a normal noise blanker would have little or no effect 
on the signal.

If there is anyone who can get a 100kHz bandwidth time 
domain (oscilloscope) snapshot of the signal or a recording 
of the signal through a 100kHz wide IF system and detector 
then we will know if it is fixable through blanking. It all 
has to come through a very wide bandwidth system. Once it 
goes through a 6kHz filter it is not fixable with blanking, 
so at least we know that much.
