Re: [RFI] Power spectrum analyzer

[Jim Brown <jim@audiosystemsgroup.com>]

I hate to be the bearer of bad news, but DC to AC inverters that don't 
make a lot of RF noise are hard to find.  A better solution is a low 
cost SDR that can run on the USB port, and find a laptop that's RF quiet 
to run the software. In addition to being cheaper, they're also far 
better spectrum analyzers in many ways. Several specific recommendations 
here.
