[RFI] [ CBC.ca ] "Something mysterious is blocking vehicle key fobs from working in a small Alberta town"

[Don Kirk]

An easy alternative to a full blown spectrum analyzer is a  chesp ($25)
RTL-SDR dongle receiver plugged into a laptop with portable directional
antenna.  Full coverage from 25Mhz to 1.7 GHz.  Easy to view the key fob
frequencies with this setup.  I use this type system all the time with an
additional HF  upconverter for tracking down MF and HF RFI.
