[RFI] SDR, Software Defined Radio?

[Jim Brown]

I've not had a radio of the sort you describe, but I do own a K3 with P3 
that allows me to do that with a max bandwidth of 200 kHz centered 
anywhere it can tune. It has I/O for transverters, and I have one for 2M.

I DO find it quite helpful in identifying the generic type of noise that 
I hear - that is, arcing, or electronic, computer clock or free-running 
device like a SMPS. There's no doubt in my mind that a SDR with 
broadband display capability and good adjustability of sweep width would 
also be quite useful if it, and the computer used with it, were 
sufficiently portable and free of noise itself.
