[RFI] HF Handy Talkie for RFI Detection?

[Tom Thompson]

Tony,

I have been using an SDRPlay ($150 from HRO) and a small laptop or 
tablet running HDSDR (free).  If you build or buy a high impedance 
preamp, you can use a 3 ft. whip with a magmount and you have a wide 
band set up that will show you the spectrum of the RFI from your car.  
When you get closer you can DF it with a loop.  I have found that being 
able to look at the whole spectrum is really helpful in tracking down 
the RFI because you can really keep track of the RFI signature.  The 
SDRPlay allows you to look at about 5 MHz of spectrum from 100 kHz to 
about 2 GHz.
